*** The DS version of LEGO Star Wars: The Complete Saga lets you fly as Jar Jar(Who you otherwise have no reason to play as) or a custom character with a blaster by double-jumping with your blaster out and shooting in midair. You can then moon jump without hacks by mashing B and Y over and over. It can also be done as Jango and Boba Fett, but it's not as easy.

* In the ''VideoGame/{{Crusader}}'' games: drop an ammo-using gun. Pick it up. Its clip is now full. Ta-daaa!

** There's a pretty famous bug/oversight in the second game's training course where you can lock Winston, her doddering old fart of a butler in the walk-in freezer, [[ButtMonkey trapping him]]. As he was creepy and sometimes got in the way of Lara's gymnastics, this was helpful.

** The fence bug allows you to slip through gaps between fences. One notable use of this is at the start of the Obelisk Of Khamoon stage. If Lara is positioned just right, she can bug through the fence, allowing her to regain access to the previous level. [[https://www.youtube.com/watch?v=3clzd_Exypo See here.]]
** The trigger bug. Enemies appear when Lara steps on certain floor tiles. In some cases it is entirely possible to glitch past these tiles, preventing enemies from spawning, or have them be ''completely'' unreactive to Lara. Sometimes you can even get past them ''legitimately'' like in ''Obelisk of Khamoon'' where if you go up a winding staircase you'll end up in an area with some chairs and a [[DemonicSpider mummy]]. You don't have to go up their immediately, and the trigger for the mummy is in the staircase, so if you wait until later when you can come in through the other way from the room with the obelisk, the mummy will just ''[[WesternAnimation/SpongebobSquarepants stand there menacingly]]'' but not do anything unless you run down the stairs and hit its trigger.

%%** ''[[VideoGame/TombRaiderLegend Legend]]'' and ''[[VideoGame/TombRaider Anniversary]]'' get the airwalk.

* In ''[[VideoGame/LEGOAdaptationGame Lego Star Wars]]'' on the Wii, there is a wonderful bug where any bonus activated will remain activated if you quit and load a different save slot.
** The DS version of LEGO Star Wars: The Complete Saga lets you fly as Jar Jar(Who you otherwise have no reason to play as) or a custom character with a blaster by double-jumping with your blaster out and shooting in midair. You can then moon jump without hacks by mashing B and Y over and over. It can also be done as Jango and Boba Fett, but it's not as easy.
** The console versions of the game have a glitch dubbed "the triple jump", where by double jumping as any lightsaber wielding character, preforming the slam attack, but changing characters ''right'' as you press the attack button will give you an extra boost. This is best done as Grievous in Prequel Trilogy levels and the Emperor in Original Trilogy levels. Unfortunately, this glitch was removed in newer games.
* ''[[VideoGame/LEGOAdaptationGame LEGO Jurassic World]]'' has the "Haunted Gyrosphere" appear in the level "Gyrosphere Valley". Zach is supposed to be trapped inside of it, but if you can get free by intentionally driving into water, switching to Gray just as it explodes, and back to Zach as he respawns. The Gyrosphere will respawn beside him, and follow you around as if it were a third teammate. It also happens to be quite useful since now you're free to hop in and out of it, making the stage puzzles much easier to solve than normal.

** The trigger bug. Enemies appear when Lara steps on certain floor tiles. In some cases it is entirely possible to glitch past these tiles, preventing enemies from spawning.

* ''VideoGame/BatmanArkhamAsylum'' and ''VideoGame/BatmanArkhamCity'' have an absolutely hilarious glitch with the ground takedowns. Rather than crouch on the poor {{mook|s}}'s chest and hit them in the head, occasionally, Batman will crouch on their head and give them a ball-busting punch in the nuts. An even rarer version has them flipped over as well, leading to Batman punching a man in the ass so hard he's knocked out. And an extremely rare one has him punch someone as a thug is getting up off of the ground, leading Batman to punch them up the ass hard enough they get sent flying.
** Something similar happens with the Multi-Ground Takedown, as sometimes thugs get knocked across an '''entire streetway''' or into the '''ridiculously high''' into the air.
** This gets a little weird when you're playing as Catwoman, because it looks like she knocks thugs out just by slapping their ass.
** Perching on a billboard or on the fences that some building roofs have and facing the corner, and then rapidly shooting quickfire freeze grenades will have Batman slowly inch towards the edge, at which point, he'll start rising into the air. Go high enough, and you can escape the game boundaries and actually fly over the walls to explore the [[SceneryPorn surprisingly detailed]] Gotham City (though there is no collision detection so you only get one glide) or across a vast expanse of water and actually reaching Arkham Asylum island, fully rendered (again with no collision detection) and then either falling through the floor and dying or falling into the water and having Batman use his Grapnel which apparently can reach across a lake back to one of the prison buildings.
* ''VideoGame/BatmanArkhamOrigins'' also has a hilarious semi-rare bug that occurs if you leave an enemy-planted mine alone along the path a cutscene happens towards, where Batman and Harleen Quinzel walk along and, [[https://www.youtube.com/watch?v=3TW_WLYSMHo#t=26s well...]]

** Something similar happens with the Multi-Ground Takedown, as sometimes thugs get knocked across the street or into the air.

* The gnome glitch from the PC version of ''VideoGame/HarryPotter and the Chamber of Secrets'', which let you create hundreds of gnomes in Moaning Myrtle's bathroom and send them running throughout Hogwarts.

** The DS version of LEGO Star Wars: The Complete Saga lets you fly as Jar-Jar(Who you otherwise have no reason to play as) by double-jumping with your blaster out and shooting in midair. You can then moon jump without hacks by mashing B and Y over and over. It can also be done as Jango Fett, but it's not as easy.

* ''VideoGame/BatmanArkhamOrigins'' also has a hilarious semi-rare bug that occurs if you leave an enemy-planted mine alone along the path a cutscene happens towards, where Batman and Harleen Quinzel walk along and, [[https://www.youtube.com/watch?v=Ip8mDUjP-cw#t=26s well...]]

* There are several notable examples of this in the ''Franchise/TheLegendOfZelda'' series:
** The [[VideoGame/TheLegendOfZeldaI original game]] has a number of glitches that allow you to cross multiple tiles of water with the ladder, clip onto blocks (and then exit perpendicular to the angle you entered, allowing you to get through diamond staircases without clearing the enemies), scroll across screens, and even go through locked doors without a key. [[https://youtu.be/HFoZOQoErww?t=1h17m33s The last of these wasn't discovered until July of 2016]], ''over 30 years'' after the game first came out in Japan. (Video intentionally set to a few minutes before the discovery.)
** ''VideoGame/TheLegendOfZeldaALinkToThePast:''
*** The "Death Mountain Descent" [[https://www.youtube.com/watch?v=cRsoMAn4TUI glitch]] allowed Link to access areas in the [[MirrorUniverse Dark World]] that should be inaccessible until after you get the Moon Pearl, which counteracts that realm's BalefulPolymorph effect. Further glitches allowed Link to actually take human form intermittently and complete certain dungeons (but unfortunately not all of them). You can use this glitch to complete the game without getting the [[SwordOfPlotAdvancement Master Sword]], and/or follow up with other illogical things like refining your regular sword into the [[InfinityPlusOneSword upgraded Master Sword]].
*** Using your [[WarpWhistle flute]] at the "wrong" time can confuse the game into [[https://www.youtube.com/watch?v=i6hx52x-Cw0 letting you]] swim on land or become the Green Flash. But this is nothing compared to what happens when you [[https://www.youtube.com/watch?v=eTO_QRPhOaQ run away from your boomerang]].
*** By emulating or taking your controller apart, interesting things happen when you walk up stairs facing downwards by pressing up and down at the same time. Interesting in that you go down a level instead of going up a level, letting you use room exits where there should be none, walking under the entire map of the game. If you use enter the Triforce room while doing this, the ending plays. This is how the game is speedrun in 3 minutes.
*** In dungeons, enemies cannot enter doorways as if there is an invisible barrier where the wall would be if the door didn't exist. This means Link can stand in doorways and be perfectly safe from enemies, but can also swing his sword or throw projectiles at any enemies who happen to come within range or enter his line of sight. This is most useful for avoiding Flying Tiles, as you can [[ProductPlacement grab a Twix]] and cool your heels while they [[NoSell systematically and helplessly destroy themselves]].
*** By attempting to use the Cane of Somaria when your magic meter is completely empty and then going into your inventory and switching to the Mushroom while the error sound is playing, you can use the Magic Powder without actually having it. This glitch has absolutely no purpose in the game as it was originally created as the NPC that you trade the Mushroom to for the Powder is accessible ''long'' before you can get the Cane of Somaria, but it can see occasional play in [[GameMod randomizer]].
*** Another glitch that can be performed in the "vanilla" (aka unmodified) game, but serves no real purpose outside of randomizer (where you may not be receiving items in anything remotely resembling the usual order) involves drinking a potion at a certain point in a hallway in the Dark Palace, preventing the screen from properly locking. Because the camera is misaligned, by walking against the right-hand wall of the next room, all of the "Mimic" enemies in the room will walk to the left and wind up offscreen, and since there are no enemies on screen, the door to the next room will open as if the enemies had been defeated. Since Red Mimics are only vulnerable to the bow, this allows you to sequence break this area if you wind up in Dark Palace without a bow (though you'll still need it later in the dungeon).
** ''VideoGame/TheLegendOfZeldaLinksAwakening'':
*** The warp glitch allowed many bizarre effects and SequenceBreaking glitches, similar to the Death Mountain glitch in ''[=ALttP=]''. This glitch is so popular that many fans actually consider the colorized DX version to be inferior to the original solely because it fixes the glitch. The glitch can unfortunately cause consequences if the player is not careful, like being stuck permanently with a companion that refuses to let you enter dungeons (the ghost Marin glitch), though it has some humorous effects, such as Moblins being replaced with the broom-sweeping old lady.
*** Getting stuck in level architecture is the most common hazard, so waiting until you obtain [[WarpWhistle Manbo's Mambo]] is a good idea if you plan to fool around extensively with the glitch. Saving and quitting is usually enough to fix the problem, but if you attempt to warp to the Face Shrine (the sixth one) or Eagle's Tower (the seventh) before unlocking their entrances and then save, there is no way to get out of them if you haven't yet learned the Mambo.
*** In some versions, warping over the edge of the map while holding everything except the level 2 sword caused you to receive a glitched object, which replaced the original sword. You had to save and quit to exit the room with the object, and loading up the game, end up in Marin's house. If you didn’t corrupt the save file, you might end up with a buggy, extremely powerful sword, which could kill anything in one hit.
*** The doghouse glitch or doghouse world, which works in both the original and color DX version. It is very easy to enter--just defeat a set amount of enemies (not doing so results in Link warping to the desert or the swamp, depending on the version) walk down the side of [=BowWow=]'s doghouse and push left--and is perhaps one of the strangest glitches in any game. It consists of every dungeon room in the game jumbled up in a seemingly random fashion. The graphics are glitched all to hell, Link's movement physics are completely changed (he can usually walk through almost anything), and treasure chests will contain anything from a random text box from the game to items from high level dungeons, which are completely usable. This glitch is almost endless in its useful capabilities, but has never been fully explored.
** While fighting Ganon, the number of bats he summons will ''almost'' overwhelm the graphic processor. You can push this over by throwing your boomerang, slowing down the action considerably and making the bats easier to dodge in a form of improvised BulletTime.
** The first Nintendo 64 offering in the series, ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', has more than a few glitches that are widely known and looked upon fondly by players:
*** Early copies of ''Ocarina of Time'' (predominantly those with a gold-colored cartridge) featured the "Swordless Link" glitch, which involved saving and quitting during the final battle right after Ganon knocks the Master Sword out of Link's hand. Doing so would put you back at the beginning of the final dungeon with no sword equipped. While this may sound lame, it was actually pretty cool -- among other things, it let you use items while on your horse, leading to some interesting and glitchy gameplay scenarios (including being able to use the dungeon-only warp spell anywhere and catapulting yourself out of the game world into the nothingness beyond). It's even possible to do this in later editions of the game, but you need to use yet another glitch which allows you to play almost any item as an ocarina to warp out of the boss's lair with your sword unequipped.
*** There's one involving the [[GottaCatchEmAll Gold Skulltulas]]. One particular Skulltula was in a small cavern. It was possible to kill this spider, use the boomerang to collect its token, then backflip onto the panel that warps you out of the cavern before the boomerang returned to you. This caused the token to be collected, but the Skulltula to return to life, allowing for infinite Skulltula tokens if used repeatedly.
*** The infamous [[https://youtu.be/YejUKyUjqgo bottle bug]] that allows players to replace any item with a bottled fairy. While the fairy in the bottle thus created can't automatically resurrect Link like the fairies in normal bottles can, and the item replaced is gone forever, this can still be quite useful for an emergency life boost in the more difficult sections of the game.
*** Similarly, when you catch a bug in a bottle and release it, three will come out. You never need to release more than one at any time so you're free to release three, catch one, and let the other two do what you needed them to do repeatedly for infinite bugs. This tactic allows for some easy money farming and is invaluable in the Spider Houses of ''Majora's Mask''.
*** Skipping all Young Link dungeons by glitching through the Door of Time and skipping all Adult Link dungeons by using the reverse bottle adventure bug. These and many more can be found [[http://tasvideos.org/ZeldaOcarinaOfTimeTricks.html here]] and make for some impressive speedruns.
*** Some players have found interesting effects by physically interfering with the connection between cartridge and console. If the player slowly lifts up one side of the cartridge while simultaneously running into anything destructible by bombs, Link might pass through the rock/wall/whatever. This allows the player to get into Goron City via the Lost Woods before getting the sword, thus giving complete (but useless) freedom. It can also be used to get past anyone who's blocking your path--like the Kokiri child who blocks your way out of the woods, Mido who stands between you and the Deku Tree, etc.--allowing you to get to Zelda and beyond without ever obtaining a sword.
*** One major glitch is the ability to "Seam Walk" by very carefully walking straight lines up the seams where two pieces of terrain meet at a gradual angle. The easiest place to do this is in the Gerudo horse archery arena but its actual uses include standing next to Biggoron (and passing through him to climb to Death Mountain's peak) and "invading" the oddly water-filled Hyrule Castle. Oddly, this glitch was never fixed: notice that in ''VideoGame/TheLegendOfZeldaMajorasMask'' the glitch is still possible, as Nintendo simply replaced most angled seams with vertical ones.
*** In Ocarina of Time: Master Quest there's an easy-to-do glitch that allows you to get through the [[DownTheDrain Water Temple]] in under 5 minutes, without needing a single key or encountering a single enemy.
*** One of many glitches exploited in {{Speedrun}}s is the "Super-slide", where you roll against something that would cause damage and put up the shield at just the right moment, causing Link to slide backward indefinitely and at tremendous speed. Entering [[CutScene Cut Scenes]] this way has interesting effects. For instance, approaching the Forest Temple the first time as an adult, Link spends the whole cut scene hiding behind his shield, even while playing the ocarina, and mostly doesn't even show up onscreen since he's unable to walk where he's scripted to. Entering the FinalBattle this way prevents Link from [[spoiler:losing the Master Sword]], with the side effect that [[spoiler:it temporarily exists in two places simultaneously: stuck in the ground ''and'' in Link's hands]]!
*** You can easily win the second horse race against Ingo by following him closely, but then stopping just before the stable at the back of the ranch. Turning to the right and then turning back makes Ingo disappear, so you can take your time getting to finish line.
*** Dark Link might normally be an infamous example of ThatOneBoss, but he goes down laughably easy if you face him with a Broken Giant's Knife. Reason being is the programmers never expected this and never gave him alternate programming, so he continues to block and defend against it as if it was the full Biggoron's Sword. Stabs and thrusts from the broken blade slip right past his shield and will kill him in ''seconds''.
*** A minor one is the Redeads in the ruined Hyrule Castle Town. Normally Redeads are annoying DemonicSpiders that paralyze Link with a screech and lurch over to bite and/or hump the life out of him, but the ones in the town aren't able to paralyze, letting Link run past what are effectively non-threats. It turns out that since their paralyze causes a camera zoom effect, it won't work in pre-rendered areas with a fixed camera position[[note]]Though it's fairly likely this was noticed during development and [[ThrowItIn thrown in]] as [[AscendedGlitch a feature]], to save players having to fight their way through a horde of full-strength Redeads every time they loaded a save file[[/note]].
*** The game can only handle one timer at once, so if it would need to count multiple down, it has to pause one. Normally, the developers went out of their way to avoid having multiple timers at the same time. The only time it's possible is entering Death Mountain Crater without a goron tunic on during the Biggoron sidequest, in which case the only timer counting down is until heat exhaustion. Because warp songs technically set the quest timer to 1 second left and don't immediately fail you, this means you can technically teleport to Death Mountain Crater without the goron tunic on, run to the exit to Biggoron's cliff, and finish with just that 1 second left.
*** Messing around with item data can lead to a bug termed [[https://www.youtube.com/watch?v=mjlyi-Ie3Us "ass chest,"]] where Link warps behind the Gerudo running the Horseback Archery Range and does his chest-opening animation. Not only can this be used to get items and aid in hundred percent speedruns, it has the funny effect of looking like he's literally pulling items out of her ass.
** ''VideoGame/TheLegendOfZeldaTwilightPrincess'':
*** A glitch allows the player to [[https://www.youtube.com/watch?v=TQF0s_el7nY get the Master Sword very early in the game,]] which includes the possibility to change form freely, even in Twilight areas. Unfortunately, the bug also makes it impossible to enter the second dungeon.
*** You can get to the City in the Sky early by transforming into a wolf into a crack under Kakariko Village to clip through it and warp the cannon to Lake Hylia. Since the game only checks for the last mirror shard, it allows you to skip a dungeon and a half. Unfortunately, the game will block all access to previous dungeons once you do the skip glitch, as the game discards all the old events because it thinks you already completed them.
*** The "Twilight Hack", a result of a particularly "meta" Good Bad Bug. [[http://catb.org/jargon/html/S/smash-the-stack.html Smashing the stack]] (that is, causing a buffer overflow) using a custom save file containing an overlong name for Epona that contained code that would run right after the save is loaded has allowed people to use the game to boot the Wii into a root-level command prompt and install homebrew software on it. It's not really a bug in the ''strictest'' sense, since (especially after the latest firmware updates, due to later hacking developments including -- and focusing on -- piracy) it can't be accessed without hacking, but its bizarrely beneficial repercussions make it worth mentioning here.
*** It only works in the second dungeon, and even then only in the places with magnet force pillars, but putting on the boots with the D-pad and then replacing them with any other item ''before'' you hit the magnetized surface allows you to move at normal speed on the ceiling. You can't use items or roll, and your hat becomes immune to gravity, but it makes some parts much faster.
*** [[https://www.youtube.com/watch?v=3UhRVt7pqkw&feature=player_detailpage The infinite-bombs-and-arrows glitch]] can be done by exploiting the connection between Iza's Rapid Ride and Plumm's Fruit Pop Flight Challenge up Zora's River. By playing the latter beforehand, and using the clawshots while swimming to clip through a wall, you can purposely fall out of bounds in Lake Hylia. What makes this glitch possible is the fact that when the game respawns you, it returns you to the place you last entered the area -- in this case, at the end of Plumm's game, which can usually only be played while you're a wolf -- however because you died as human Link, you'll be respawned as human Link, in a situation that shouldn't be possible. After a few more deaths and respawns you can get so Wolf Link is playing Iza's game (another impossibility), but isn't in the boat. This allows you to warp out and when you turn human again, you'll still have the infinite bomb arrows assigned to your B button, as though you were still playing Iza's game. Having unlimited bombs and arrows makes the Cave of Ordeals a whole lot easier, [[ThrowDownTheBomblette among other uses]].
*** In the UsefulNotes/NintendoGameCube version of ''Twilight Princess'', pressing the reset button on the console at ''just the right moment'' after Link falls into Lava in the Goron Mines (sometime during the fade to black) causes Link to respawn normally, except in Hyrule Field. He can then run around, and you might notice the title music playing. The Title logo will eventually pop up, and pressing any button besides the control stick will cause the game to go into the file select screen. It's also possible in the Wii version, although the timing must be very precise and it's harder to pull off. Also sometimes Link can spawn on a Bridge of Eldin; in that instance the glitch needs to be used again. If done correctly, the area which supposed to be Hyrule Field rendered ''behind the Title logo screen'' becomes fully ''explorable''. This can lead to going outside the boundaries of the level, including going as far as the end of skybox, or watching the miniaturised textures of places which are in the distance, like Hyrule Castle. Oh, yeah. Epona is a '''MUST''' when going outside the walkable area, so prepare to see some flying horses.
** ''VideoGame/TheLegendOfZeldaMajorasMask'':
*** It's possible to wear the boss-only Fierce Deity's Mask virtually anywhere thanks to the glitch-filled Sakon's Hideout. Simply wear a mask during the second last section as Link, then when you swap to Kafei exchange that mask for the Fierce Deity's. The very first thing Link will do when you regain control of him will be to put on the mask he was "wearing" just moments before, and he will transform. Use that with a bug that lets you enter Sakon's Hideout on [[strike:Day 2]] [[https://www.youtube.com/watch?v=OWnF-n-yZVk Day 1]] and tell the Bomber Kid the password earlier on, and you can pretty much mess around anywhere you want for two full days with newfound superpowers. Just be careful not to talk to anyone whose lines varies based on which of the mask forms you're in -- since the Fierce Deity is boss-only, those [=NPC=]s aren't programmed to properly react to it, causing the game to crash. This glitch also leads to some other weird glitches; if you talk to some characters, they will react as though Link were not wearing a mask at all. Some react to him as though he ''were'' transformed, but they don't make a form-specific remark.
*** You can keep looking through the telescope as the screen fades to black from running out of time. If you then press B to exit the telescope screen, the game does not end. All the time based events disappear and there is no timer. This is commonly referred to as the 4th Day Glitch.
*** The Blast Mask will normally create an explosion that damages you for half a heart when you use the attack button. Put up your shield and then use the attack button, and your shield will protect you from the explosion that's ''on your face''. This is still present in ''Majora's Mask 3D'' and is [[AscendedGlitch referred to as though it were intentional]] by that version's strategy guide.
*** A ''very'' easy to perform glitch allows you to warp to any Owl Statue before you've actually visited them[[note]]It involves learning the Song of Soaring and hitting the "hidden" Owl Statue visible from West Clock Town which has no warp index and no others. Depending on where your menu cursor was before playing the song, the cursor will be placed on one of the destinations to warp to[[/note]]. With this you're able to [[OpeningTheSandbox smash the sandbox wide open]] and gain access to a ton of items, heart pieces, and all the transformation masks without ever setting foot in a single dungeon.
*** In the 3DS version, standing on the edge of a platform and setting up a bomb behind you makes you jump a lot of distance forwards, which can be used to skip the green valve quest of the Great Bay Temple and get the Song of Storms after the night of the first day, among other examples. This trick also exists in the N64 version, but isn't as powerful.
** The ''entire [[NewGamePlus second quest]]'' of the [[VideoGame/TheLegendOfZelda original game]] exists due to a programming error. The map data for the dungeons used only half of the intended memory on the ROM, but Shigeru Miyamoto decided that [[ThrowItIn it played just fine and decided to use the extra space for an alternate layout]].
** The Use Restricted Items glitch in ''VideoGame/TheLegendOfZeldaOcarinaOfTime 3D''. Not only does it allow you to use certain items and weapons in buildings and other areas, but to use Farore's Wind anywhere, letting you use any spot in the game as a checkpoint. It then gets better when you realise that you can use it to escape the final battle without a sword, accessing all known effects of the original Swordless Link gitch, or that you can break the camera system and activate a free camera in areas like the market and Temple of Time.
** In ''VideoGame/TheLegendOfZeldaTheWindWaker'', there's the unlimited potions/soup glitch. Just press the button the item is assigned to and start at the same time, then switch it out for an empty bottle. Link still drinks the soup or potion, but it not only doesn't use up the stuff in the bottle but can even end up half filling the empty one as well. You can also use this to use items you're not supposed to use in certain areas, like bombs inside shops and houses and such like. An interesting thing to note about using bombs inside buildings is that this can be used to blow up the delivery boxes inside Dragon Roost Island. They appear nowhere else in the game and this glitch is the only way to destroy them.
** The main glitch used in speedruns of ''VideoGame/TheLegendOfZeldaSkywardSword'' is nicknamed Back In Time, and it involves dying, selecting Continue and resetting the game immediately afterwards: if done correctly, Link will still be controllable while the game is otherwise in the title screen. Depending on where and how it's performed, you can use it to skip large parts of the game by forcing the game to trigger cutscenes when it shouldn't, instantly warp to another save statue in Skyloft for a major shortcut and end up in partially-loaded dungeon rooms with missing obstacles that you can bypass earlier than you're supposed to.
** ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'':
*** It's possible to skip the boss fight of Skull Woods. When it uses the rocket punch, use the Tornado Rod to fly up, clip into its body upon landing, and then quickly walk through the closed door to the outside. Done correctly, you'll end up in the area with the Skull Woods' Sage portrait. You'll still have to fight the boss if you want a Heart Container (it'll still be there when you return), but for speed runs and [[SelfImposedChallenge three-heart runs]], that's little concern.
*** There's a trick to get Ravio's shop early. You must lure a crow near the entrance of the Death Mountain then getting hit by it as you jumps off the ledge. The Death Mountain eruption cutscene triggers the appearance of Ravio in your house. [[https://www.youtube.com/watch?v=IbSShVKW6pY#t=27 Here's the video.]] Not only is this trick useful in speedrun, but it has funny oddities: if you complete the Sanctuary the cutscene in which Link wakes up is glitched and there will be two Ravios and two Sheerows!
** ''VideoGame/TheLegendOfZeldaBreathOfTheWild'':
*** The Magnesis rune cannot be used to lift metal objects you are currently standing on. However, this can be circumvented if you put ''another'' metal object on top of that metal object. This works best with metal boxes being placed in mine carts, standing on the box, then lifting the cart into the air however high you want. Branli's gliding minigame on the Ridgeland Tower becomes trivial with this exploit.
*** Similarly, if you use Magnesis to push a metal weapon into an object, and walk Link into the object at the same time, Link will push the object aside as though he had infinite mass. This means giant doors, large rock spheres, and other such things can be casually pushed aside instead of puzzled open.
*** Warping from the Trial of the Sword to an incomplete Divine Beast [[https://www.youtube.com/watch?v=L8rTSJKAgxA could be used to activate a bug called 'World Reset'.]] This bug resets all treasure chests on the overworld (including those with gems, money, key items and Champion weapons), as well as lets players get as many seeds from the Korok as they want or farm infinite ancient parts by flipping over a dead Guardian. As you can guess, it completely breaks the game wide open. Pity Nintendo patched it out with an update.
*** There's a trick to get tons of free compendium pictures. Just finish the Sunshroom Sensing sidequest at the Tech Lab up until Symin is about to introduce the photo buying mechanic, then sell a bunch of the same item in a shop. [[https://www.youtube.com/watch?v=qDLGFKoEsPs Once you return, Symin will give you as many free compendium pictures as there were sold items at the shop.]] This lets you finish the materials section instantly, or even unlock pictures of weapons or bosses long before you encounter them.
*** Holding on to objects that have been hit while in [[TimeStandsStill Stasis]] at ''just'' the right way will send Link flying with them[[note]]Normally, trying to "ride" an object under Stasis will simply have Link fall off[[/note]]. In addition to looking cool, it's also useful for speedrunning the early parts of the game, before getting a horse.
*** There's a strange quirk in the game's physics that causes certain airborne objects to speed up dramatically when Link uses his BulletTime ability when they're in the air. A Cryonis pillar just happens to have a few frames where any items on it become airborne for a split second. Shoot at ''just'' the right time in midair, and you now have a functional refuse launcher. This in itself is [[RuleOfFun pretty useless aside from being fun to watch,]] and [[CatharsisFactor blasting away empty chests that had crappy contents,]] as you can't do that to yourself. Normally. There's an advanced version of the bug that involves Ice element weapons, shield surfing, and any enemy that goes into [[RagdollPhysics ragdoll mode]] when stunned or killed, which includes any non-boss enemy other than Lynels, Yiga Clan goons, or Guardians. Freeze your target with an Ice attack, then shield-surf onto their heads from a high place, such as one of the encampment's nearby watchtowers. The enemy ragdolls upon you performing a GoombaStomp on it and bringing it out of the "frozen" state, and this confuses the game and somehow shoots you into the sky like a cannon. If performed on the right angle on the enemy's back and a shield spin is performed at the same time, it sends you flying at Mach 5, fast enough that the game needs to take a breather to load the world, and fast enough to shoot you from the Great Plateau to Hyrule Castle.

* ''VideoGame/YumeNikki'' has a useful glitch that can boost your speed to the max ''VideoGame/RPGMaker 2000'' speed (8x, if anyone's counting), making you amazingly fast. You just had to sit at your desk in the dream world, use an effect (using the bike effect made you even faster) and get off the chair. Especially useful for finding the rest of the effects!

*** If you attempt to warp to the Face Dungeon (the sixth one) and save, there is no way to get out of it, even with the warp glitch.

* ''VideoGame/AssassinsCreedIVBlackFlag'' and the [[https://www.youtube.com/watch?v=9pQ_ZozZIio ascension of the Jackdaw]]. Too hilarious for being told, so it is put under spoiler: [[spoiler:something happens in the code for the ship when at the docks, the sea underlevels, while the crew starts ascending to the skies like Jesus]].

*** It only works in the second dungeon, and even then only in the places with magnet force pillars, but putting on the boots with the D-pad and then replacing them with any other item ''before'' you hit the magnetized surface allows you to move at normal speed on the ceiling. You can't use items or roll, and your hat becomes immune to gravity, but it makes some parts much faster ([[MostAnnoyingSound and quieter]]).

** The first five games have corner bugs, where jumping into a corner at the right angle makes the game think you are on top of it, causing you to warp to the top. This allows access to normally inaccessible areas, and therefore massively increases the amount of possible exploration in the games (as well as being helpful for things like {{Speedrun}}s).

** The [[VideoGame/TheLegendOfZeldaI original game]] has a number of glitches that allow you to cross multiple tiles of water with the ladder, clip onto blocks (and then exit perpendicular to the angle you entered, allowing you to get through diamond staircases without clearing the enemies), scroll across screens, and even go through locked doors without a key. [[https://youtu.be/HFoZOQoErww?t=1h17m33s The last of these wasn't discovered until July of 2016]], ''over 30 years'' after the game first came out in Japan. (Video intentionally set to a few minutes before the discovery).

* ''VideoGame/KingsQuestVAbsenceMakesTheHeartGoYonder'': Play the DOS version with the CD for the Windows version in your disc drive. The game will try to read the audio files off of the disc... [[https://www.youtube.com/watch?v=RqunFIEI1IY the wrong audio files]]. You'll get entirely the wrong dialogue being played with entirely the wrong scenes, turning the plot into gobbledygook, in addition to sound effects replacing dialogue, dialogue bits replacing sound effects, songs from nowhere, hammers going "boo-boop" and rivers telling you to quit.
