Screw up while doing a puzzle? Did you [[BlockPuzzle move the blocks]] the completely wrong way? Accidentally destroy the crate you needed to reach the high ledge? You're [[{{Unwinnable}} completely screwed]], right?

Nope! Simply exit and reenter the room, and more than likely everything will have been restored back to its default position. Convenient, isn't it?

Particularly pragmatic developers will include a Puzzle Reset for puzzles that ''should'' be impossible to get stuck in, to avert a possible GameBreakingBug.

Cousin to EverythingFades and RespawningEnemies. This appears very frequently with {{Block Puzzle}}s. An [[AcceptableBreaksFromReality Acceptable Break From Reality]], because it would not be that fair to make the puzzle unwinnable because the player accidentally blocked completion.

* It's interesting to note that, in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', you can't PuzzleReset the Gerudo Training Grounds if you start using keys on the wrong side of the final room. However, there are enough keys to open every door, it's just that some of them are only available after you get the Silver Gauntlets, which you don't have when the Training Grounds are first accessible.
** ''VideoGame/TheLegendOfZeldaALinkToThePast'' had one puzzle (the infamous Ice Palace) that required PuzzleReset to beat. It was so annoying and non-obvious that the UpdatedRerelease replaced it entirely. That said, in the original version you could still skip the puzzle by completing a later dungeon first, giving you access to, essentially, the Cane of Puzzle Skipping.
** This is the one thing that most fans dislike about ''VideoGame/TheLegendOfZeldaPhantomHourglass'', which has a dungeon -- the Temple of the Ocean King -- that must be revisited over and over. Each time, all previously-solved puzzles have reset themselves and must be redone in order to advance farther down in the dungeon. Did we mention this is a ''TimedMission''?
** ''VideoGame/TheLegendOfZeldaMajorasMask'' exaggerates this with the GroundhogDayLoop mechanic. Every time you play the Song Of Time to go back to day one, all dungeons and side quests are completely reset, and you lose your InterchangeableAntimatterKeys as the doors are relocked, among other things.
* ''VideoGame/{{La-Mulana}}'' goes out of its way in the manual to tell you that there are things you can [[LostForever screw up forever]]. Strangely enough for a game that proclaims its difficulty loudly, most puzzles are resettable (including the complicated {{Block Puzzle}}s in [[BrutalBonusLevel Hell Temple]]), and you always have the option of loading a save and trying again.
* ''VideoGame/GoofTroop'' makes resetting a puzzle after making a mistake just a matter of crossing back to the last screen for a moment.
* In ''VideoGame/GodOfThunder'', not only can you reset a room by leaving and coming back, you can literally [[PressXToDie Press D to Die]] and do it right now. This rolls back everything you did since you came in, so you can also use it to undo mistakes like killing an NPC (which [[VideoGameCrueltyPunishment costs points]]).

* ''VideoGame/GodOfWar'' takes this one step further, as you needn't even leave the room for the puzzle objects to reappear. For example, at one point early in the game you're tasked with pushing a crate past a group of archers on a higher ledge. If the enemies destroy the crate, a new one automatically appears in the original position mere seconds later.
* A particularly weird example appeared in the ''Franchise/TombRaider'' series--boulder traps would often reset, as if the boulder had spontaneously rolled back uphill, until they were successfully passed. And sometimes then, as well. Occasionally the opposite would happen, usually when it was least convenient.

* Both ''VideoGame/AnotherCode'' games let you simply back out of the puzzle with no harm done.
* ''VisualNovel/HotelDuskRoom215'' and ''VisualNovel/LastWindow'' both normally let you just back out to reset any puzzles. However, doing so in one puzzle in Chapter 9 of ''Hotel Dusk'' will get you a GameOver, since doing so means you're giving up on someone and failing to save their life.
* ''VideoGame/{{Myst}} IV: Revelation'' is notable for having certain puzzles (such as one involving moving monkeys around trees in order to lure a carnivore, blocking your path, into a trap) which do not reset after leaving. (This is particularly ironic in light of the fact that the above puzzle clearly shows the carnivore leaving the area to follow you -- and then returning to exactly the position it was in before you left.)
* Phenomenally generously for a ''Creator/{{Sierra}}'' game, there's a section in ''VideoGame/SpaceQuest 5'' where you have to punch holes in certain sections of a card to get it to let the correct lasers through a security lock to open it - and if you get a position wrong, the game explicitly tells you that you've messed it up and gives you the opportunity to reset it, at the cost of a few points. Of course, more traditionally, if you didn't actually pay attention to where said lasers were when you had the opportunity to look at them a while ago, [[{{Unwinnable}} you're stuffed]].

* The sliding-block puzzles in ''VideoGame/StarFoxAdventures'', specifically, the ones where a simple shove sends them sliding like they're on ice, only require that a block hit a wall in order for the puzzle to reset.
* ''VideoGame/DeBlob'' has a strange take on it. Your color meter, as well as your color itself, are reset to how they were before you started a mission, yet nothing else is.
* In ''VideoGame/{{Purple}}'', you can find doors whose only function ''is'' for reseting a puzzle.
* [[VideoGame/NoTimeToExplain No Time To Explain]] has certain hazards that are utilized in small puzzles that cause you to restart entire levels if you die on them, like fire. Some spikes do this too.

* The ''{{DROD}}'' series is particularly egregious, as due to its use of monsters as puzzle elements you get both RespawningEnemies and puzzle reset. It even resets some puzzles that have been solved (those these usually have the potential to make the game {{Unwinnable}} otherwise). The games usually manage to work in at least one puzzle that relies on this behaviour for its solution.

[[folder: Roguelike ]]

* The [[BlockPuzzle Sokoban]] sub-level in ''VideoGame/NetHack'' most definitely does not reset under any circumstances. Fortunately, you don't ''have'' to finish it; you just get one of two very useful magical items if you do, plus a pile of gold. Additionally, there are several ways to "cheat" if you mess up, though each act of cheating grants you [[LuckStat bad luck]].

[[folder: Role Playing Game ]]

* In the ''Franchise/{{Pokemon}}'' games, this can be done while [[BlockPuzzle pushing boulders]] in caves and dungeons. One puzzle in Sylph Co requires a version of this (where mooks are sent back to their original position) to beat.
* ''VideoGame/PokemonXDGaleOfDarkness'' has one puzzle that can ''only'' be solved using the reset - a crate that must be slid into one passageway to unblock another, and the only way to get through the freshly-blocked passageway is to exit and then reenter using the passageway you unblocked.
* Puzzles in ''VideoGame/BreathOfFireIII'' would do this.
* Same goes for ''VideoGame/SkiesOfArcadia''.
* Exception: in ''VideoGame/SecretOfEvermore'', if you screw up the jumping puzzle in the pyramid you have to reload and do it again. Unless you saved after screwing it up, in which case your game is now {{Unwinnable}}.
* ''VideoGame/VagrantStory'' would do this with failed and ''successful'' puzzles alike, forcing you to redo them just to get back to where you needed to be. On the plus side, it would occasionally time and rate your completion of a room on subsequent visits.
* The puzzle-rich ''VideoGame/LufiaIIRiseOfTheSinistrals'' included a "Reset" spell to reset any puzzle you screwed up, in case [[GhostButler leaving and re-entering the room isn't an option]].
* ''VideoGame/GoldenSun: The Lost Age'' actually has solving a puzzle depend on the room resetting when you leave. (To move a pillar needed to reach a treasure chest, you need to step on a breakable floor tile. This makes it impossible to actually GET to the treasure chest without falling through the floor and resetting the room. To get the chest you need to exit through an exit near the pillar, go back in, move it, then cross the floor tile that would be already broken if not for this trope.)
** Another puzzle uses a lever to reset it because you can't leave the room (unless you use magic to leave the entire dungeon).
* In ''VideoGame/WildArms1'', where puzzle segments are heavily based on ''Zelda'', there was an actual ''item'' to reset the room, but it was almost never used. The rooms reset if you leave them anyway. It ''does'' save the player the trouble of walking all the way back to the entrance though.
* ''ShadowHearts: Covenant'' has a variation - the adjustable stairs in the Neam Ruins won't reset unless you leave the dungeon entirely, which can be a hassle if you screw it up so badly that you can't get it back to the neutral position.

* The ''Franchise/ResidentEvil'' series features this a lot. Except in the case of one sliding block puzzle in 4.

* Freddiew's [[http://www.youtube.com/watch?v=dXmMQJMFL_I Zelda Pot Smasher video]] illustrates perfectly the ridiculousness of how things that have been smashed into smithereens become perfectly fine when you just go out from a room and come back again.
