** The "NAT test glitch" allowed UsefulNotes/XboxOne players to glitch themselves into a solo public lobby[[note]]Simplified explanation: going into the [=XBox=] menu and choosing the "Test NAT type" option would create a lag spike big enough to kick you out of your session and into your own, but not big enough to kick you offline completely[[/note]], meaning you could make money without interference from other players. Unfortunately this was patched in 2021 (with a similar glitch for the UsefulNotes/PlayStation4 patched around the same time), though this became a moot point a few months later when Rockstar lifted all restrictions on private lobbies, making the glitch unnecessary. Rumors quickly spread that Rockstar did this because they noticed a steep drop-off in players, as a lot of ''GTAO'' players (especially the car collectors) would rather not play than deal with [[{{Griefer}} other GTA players]].

*** Thanks to glitchy furniture hitboxes, people have used them to make unusual buildings such as [[https://www.reddit.com/r/Palworld/comments/19cv0wa/found_a_way_to_make_custom_stairs_via_the_use_use/ staircases]] and [[https://www.reddit.com/r/Palworld/comments/19cevlu/found_a_pretty_cool_way_to_build_a_lamppost_to/ lampposts]].

** Using a powerful but long-cooldown attack when mounted on a Pal, then dismounting it will somehow allow the Pal to recharge this attack and likely use it immediately. This allows you to execute attacks like Faleris's Phoenix Flare twice in succession, which can put a good dent in the health of Alpha Pals.

** By getting guards to attack you before entering a Tower to fight the boss, they will spawn during the tower boss fight. As long as the Guards are the only ones to deal damage to the boss, it becomes possible to [[https://www.youtube.com/watch?v=vqShPXmmL0I capture that Tower's boss along with the human]], allowing you to use those bosses as Pals. And ''boy howdy'' can they be absolute {{Game Breaker}}s, given that not only are their boss mechanics and overinflated stats perfectly intact when caught, but they'll only get stronger as they level up. This was removed in version 0.1.5.0 (''unintentionally,'' according to the game's official Twitter/X account which [[https://x.com/Palworld_EN/status/1762375046839083320?s=20 apologized for fixing the bug]] as a consequence of the other stuff they fixed).
** While it was quickly patched out, it was possible for Pals attempting to transport large quantities of materials to get stuck in a loop of picking up and dropping the same objects repeatedly. This would simply be annoying if it weren't for [[ToiletHumor the animation]] making it look like the Pal is [[BowelBreakingBricks uncontrollably defecating wood/rocks]].
** The Nature Preserve islands are filled to the brim with rare, powerful Pals that you can't find anywhere else save for a few available as bosses along with treasure chests full of powerful items, but just setting foot on them is a crime that'll get the PIDF on your trail. However, the emphasis is on "[[LoopholeAbuse setting foot]]": the game never checks if you're actually ON the island until your feet make contact with it, which means staying mounted on a flying Pal like Beakon will let you flaunt your poaching in front of the PIDF Elites patrolling the island who only turn hostile if you're committing a crime, which you technically aren't, because the game says you aren't. This was patched out in 0.1.5.0; now riding in the nature preserves will be considered trespassing and the PIDF patrols there will turn hostile.

** When you attempt to capture a Pal, your Pal Sphere will float in the air until it either fails or succeeds in doing so. In that time, it's possible to jump on top of the ball. After a successful capture, you'll be ''rocketed'' straight up into the sky. Combine this with the glider and it's a pretty useful way to get your bearings in unexplored areas during the early to mid game. Just don't try this if you ''haven't'' unlocked it yet [[NotTheFallThatKillsYou for obvious reasons.]]

** Due to their rotund model and its habitat being full of trees, Mozzarina has a notable tendency to spawn on top of said trees very often. It looks utterly hilarious seeing a plump cow balancing on top of a tree.
** The "Crumbling Wall Exp" glitch consisted of building three platforms, three walls attached to the platforms, attaching a two segment long roof facing outwards, attaching a staircase to the roof and then placing a wall at the junction of the staircase and second segment. This is recognized as a valid building spot, but actually ''attempting'' to build the wall causes the new wall to instantly break, dropping lumber and granting experience points from building the wall.
** If you climb onto a dungeon wall and then feed your pet, then mount it, you're almost guaranteed to end up through/above what surface you were climbing. You can walk, ride, and fly around plenty of out-of-bounds areas with such, and even use this trick to skip a dungeon path and get straight to the boss (and/or the rewards behind it, which normally require the boss's defeat).
** If a mountable Pal clips inside terrain and you attempt to ride it, you'll get pulled inside the terrain. This is easily remedied by releasing your Pal outside the terrain and attempting to ride it, pulling you out.

** When the Mistlands update originally released, a glitch would occasionally make the Mistlands biome boss [[spoiler: The Queen]] [[https://www.youtube.com/watch?v=6C1TOcjejhY spawn outside of the instanced boss arena.]] This also had the unintentional effect of making the boss significantly easer, as it would prevent the boss from burrowing and summoning mobs.

* ''VideoGame/{{Terraria}}'':
** Examples which are still "at large":
*** The liquid physics have their own issues, allowing players to create water and lava "generators" that take a small amount of either fluid and duplicate it infinitely. The basis of this behaviour is that when liquid falls on an elevation that is a single block wide, half of it flows down on either side. Setting up a large pyramid consisting of individual blocks with space between them and pouring liquid on the top will cause it to be divided and divided over and over again until the amount is too small to be divided. The game solves this by having the minimum amount still fall down on either side, doubling it at each division.
*** Minimizing the program in a certain way causes it to run ridiculously fast in the background. This is handy if you want to park somewhere safe and wait for nightfall/daybreak, or if you've set up an automated monster-farming trap and want to wait for a bunch of RandomDrops.
*** The differences between water and air pressure is ignored, so you can dive 300 meters underwater, dig a small tunnel, then dig up a bit into a roomy cavern, and the cavern will not get wet at all (to get the idea, imagine a J-shaped test tube that can fill all the way up on the right side without the left side overflowing).
*** During the Blood Moon, zombies can bash doors open, but only inward. Putting something that occupies the space but doesn't have collision (a cloth banner or another door, open in the opposite direction, for example) will make the door impossible to open inward, meaning that you can come and go freely but the zombies won't get in. It should be noted, however, that goblins (to be more specific, peons) don't have this problem as they bash doors ''completely off the hinges''.
*** With [[{{MenuTimeLockout}} autopause]] turned on, you can swing your sword and pause in the middle of the animation to click a potion up from your inventory, unpausing will consume it, ''even if you have the Potion Sickness debuff that would have prevented you from consuming it in the first place''.
*** Light Discs, the Dao of Pow, and the Shadowbeam Staff, if used in just the right way, can actually glitch through one-block-thick walls.
*** After the 1.2 Big Update, it is possible for worldgen to create a Lihzahrd Temple in the Jungle with a messed-up layout that allows you entry into the Temple without having defeated Plantera and getting the Temple Key to unlock the door.
*** After the 1.3 Big Update, it is possible for worldgen to accidentally generate a Granite or Marble Cave mini-biome that overlaps part of the Lizhard Temple, similarly allowing you to break sequence and enter it long before beating Plantera.
*** An interesting and much-exploited collision detection/clipping/zipping bug that was introduced by the sloped blocks in the 1.2 Big Update has been dubbed the [[http://www.terrariaonline.com/threads/hoik-guide-rapid-player-npc-etc-transport-using-only-sloped-tiles.160618/ "HOIK"]]. Yrimir has demonstrated this bug by [[https://www.youtube.com/watch?v=iHw06h2L-rc slaying the Dungeon Guardian]] with a HOIK setup that allowed him to attack it with impunity while zipping around it in a circle. WordOfGod has confirmed that no specific efforts will be made to fix the hoik glitch.
*** The Lihzahrd altar can spawn directly below a low ceiling on world generation, which completely immobilizes the Golem's main body when summoned by the fact that the golem spawns directly above the altar and main body cannot move through rocks. Assuming you can still get a clear shot at the body in this state and damage it, the fight becomes laughably easy since it eliminates much of the need to dodge the main body's attacks, allowing you to pick off the body parts at your own pace.
** Examples which have been "fixed":
*** Prior to 1.1.1, trying to place a recorded music box on a table would duplicate the item by a massive amount, these boxes sell for two gold ''each''.
*** Like all bosses the Eater of Worlds flees if he kills the player and there are no other players nearby to challenge him. Prior to 1.0.6 the Eater of Worlds was considered ''slain'' when he fled complete with full drops, allowing you to run back to the battlefield and collect its loot.
*** Early after the 1.2 Big Update, canny players were able to use Actuators to force Lihzahrd Bricks into the background, allowing access to the Lihzahrd Temple without beating Plantera and getting the Temple Key. This was soon fixed. Likewise, they used to be able to use a Teleporter to bypass the door. Both of these were 'fixed' by making it so that Teleporters and Actuators could not work in the Lizhard Temple biome ''until'' you defeat Plantera.
*** For a short time (About a Week) of the 1.2.4 update, if you set up minecarts in a particular way and held the break button after getting some automated speed, you could go into hyperspeed. If you used an item during this time, you'd go flying off the minecart and PHASE THROUGH SOLID MATTER.

** The explosion caused by Bile Bombs can actually cause damage through walls. Not the most useful thing normally since it damages enemies very slowly... until you get to the Infested Mines in the endgame, which consist of small tight hallways filled with ''swarms'' of [[DemonicSpider Seekers and Seeker Soldiers]]. Chuck bombs at the walls near them and they will slowly die on their own. A similar trick also works with the shockwave caused by great hammers like Frostner, as the shockwave also can travel through obstacles (big help for dungeon areas)
** The Abyssal Harpoon is a spear with rope attached to it, and it's main purpose is to [[YouWillNotEvadeMe pull enemies closer to you and prevent them from running away]]. But as {{WebVideo/SoundSmith}} [[https://www.youtube.com/watch?v=o8v7HCg-TRs figured out]], speared creatures build up force if they get stuck on something, which when they get unstuck will send them flying a short distance. And because players can be speared as well, and sitting in a chair counts as being "stuck", this exploit could be used to send players to ''the other side of the map'' in seconds.

* ''{{VideoGame/Valheim}}'': The game updates the world less frequently than it does player inventory. This means that after a game crash, the player will respawn at their latest spawn point with their inventory but the world won't change (allowing for things like instantly transporting non-portal items like metals to a home base, or getting a free portal since dismantling one puts the materials in your inventory but the portal will still be there).

* While the Orwellian police patrols have become a source of frustration among players of ''[[VideoGame/MafiaTheCityOfLostHeaven Mafia: Definitive Edition]]'', a bug in the game's facial effects system causes Tommy to somehow lipsync to police reports made by civilians which leads to some rather [[https://www.instagram.com/p/CGHoSR-gOCm/ unintentionally hilarious moments]].

* In the game ''BoneTown'', one is able to have normal sex with the special characters in the Fantasy Mansion. Just need to stand far away from said woman, and slowly move in while hitting the Enter Key until the scene occurs.

* ''VideoGame/GoatSimulator'' is basically GoodBadBugs: The Game. The game outright advertises "millions of bugs!" [[UpToEleven as a feature]], and the devs fix none of them except the ones that outright crash the game, due to RuleOfFunny.

* In ''VideoGame/GrandTheftAutoIV'', there is a swingset in the game's version of Brooklyn that is unintentionally buried inside the concrete under it. The physics engine realizes this is a problem, and constantly attempts to dislodge the swingset with brief moments of infinite force. If you drive a car onto the swingset (or climb on it yourself), said infinite force will destroy the vehicle, kill the person... oh, and [[MegatonPunch launch both of them into low Earth orbit]]. It's a popular spot for Website/YouTube videos.

* Like ''VideoGame/DwarfFortress'', the strange interactions of ''VideoGame/{{Minecraft}}'''s world create a lot these: Swimming up waterfalls? Teleportation via minecarts? Sand-on-torch floodgates? Glitch after glitch has been discovered, explored, and developed by the massive Minecraftian community, before being turned into yet another incredible, important and intriguing tool for future players. They've started fixing them now, much to the dismay of players who can now drown in a small waterfall.
** No mob in the game can see you through glass, they all treat glass as a solid object - until they can 'see' you at least once, following which they will be able to detect you through ''any'' block.
** A (now patched) glitch let you duplicate items by storing an item inside a chest, then closing the chest while still dragging the item, causing a dupe item to drop in front of you. Although the duped item would disappear if the player attempted to use or stack it, it could still be used to craft, making mass production of iron or diamonds a reality.
** The booster cart glitch, which allowed minecarts to speed up considerably, had an entire subway system founded on it. Notch, one of the game developers, didn't get rid of them in a timely fashion, but added in a replacement feature (powered rails) that works without any glitches, albeit differently. He then proceeded to remove the glitch boosters in the next patch, along with boat elevators and rapid-ascent water ladders, to the dismay of the community.
*** In an attempt to make powered minecarts work again, the glitch (albeit weaker, but still useful) was reintroduced. Notch and Jeb just can't win.
** Speaking of rails: a glitch - [[strike:probably fixed by now]] still unfixed as of 2016 - lets players build a contraption of pistons and switches that duplicates powered and activator rails by exploiting the rail mechanics. Make one on top of funnels, tape mouse button down, come back a half-hour later to stacks upon stacks of rails. As this doesn't work on normal rails, you can always tell if a server has players who know about the glitch by checking whether it contains entire railways made of nothing but inert activator rails. Others exploit this by doing away with powered-rail calculations altogether, and just make the whole damn network out of powered rails with redstone torches sprinkled liberally around.
** If a multiplayer server is experiencing significant lag, you can see flying squids.
*** More importantly, if it lags enough that it doesn't generate the terrain quickly enough, it can let you see underground. A split second is all it takes to see hidden mineshafts and structures.
** Normally sand and gravel blocks will be subject to gravity (the only two blocks in the game that are) and fall down if you remove the block supporting them. However, due to the way the game world is generated, you can end up with floating sand/gravel blocks. If you place a block next to one of these, the physics engine will recalculate the floating blocks which can result in large areas of apparently solid land suddenly caving in and collapsing. If done right, you can use this to make pitfall traps, or just make cool floating structures that shouldn't be possible.
*** In some of the older versions of the beta (prior to 0.8), using "404" as a world generation seed would create a gravel patch in this manner; upon destroying one of the gravel blocks, the sand and gravel in a rather large area would spontaneously collapse and reveal a giant sinkhole from sea level to near-bedrock. Various players had thus participated in the "404 Challenge", which involved surviving in the sinkhole with (among other limitations) no torches.
** While not strictly a glitch, the water physics in ''Minecraft'' are very peculiar and players have found all sorts of inventive ways to exploit this to their advantage.
** As of 1.7 there's a glitch that allows the player to duplicate any object they can place in a flowerpot, by destroying or moving the block bellow the flower pot. The use of redstone can turn this into dye factories or semi-automatic tree farms.
** A lot of things done by the Minecraft technical community rely on bugs and glitches to work. Infinite concrete dupers, infinite TNT generators, automatic tree farms, ender pearl railguns, and many more creations rely an various bugs, some of which are so vital people have forgotten they weren't intended features. Quasi-connectivity, which activates pistons in a way that shouldn't be possible, is probably the most widely-used bug.
** The Hypixel server's version of [=SkyBlock=] allows you to fly with DoubleJump and the grappling hook item, [[https://youtu.be/vLLJAiII6p4?t=394 as discovered by]] ''{{LetsPlay/Technoblade}}''.

** If you position your character on a ledge just right as the police are moving in to arrest him, a long line of police will jump onto the ledge and fall off like lemmings. Works when you hide next to billboards too. (See example [[https://www.youtube.com/watch?v=tbIiDVe1qs0 here.]])
