[[quoteright:350:[[VideoGame/StrangeCasesTheTarotCardMystery http://static.tvtropes.org/pmwiki/pub/images/rsz_mirrorpuzzle_8141.png]]]]

Simply put, this puzzle involves a room that contains a light source and a number of mirrors, and requires the player to position the mirrors in a way so that the light will bounce off them in succession and hit a target. May also happen with a laser or magic beam, or [[MirrorsReflectEverything something else entirely]]. (Additional complications can include the beam killing the player if they touch it, so the player may also need to ensure that they have safe passage through it.)

This is cousin to the BlockPuzzle, and may sometimes be ThatOnePuzzle.

[[folder: Other Games ]]


* This is the recurring thematic puzzle in the Spirit Temple in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' (but only for Adult Link, since Child Link is unable to use the Mirror Shield), the Earth Temple in ''VideoGame/TheLegendOfZeldaTheWindWaker'' (with mirrors that always reflect "forward", and notably both you and your EscortMission have reflective items. At times, you must use your shield to bounce light onto her mirror, to illuminate a third mirror, which reflects light onto a series of other mirrors), and the Stone Tower Temple in ''VideoGame/TheLegendOfZeldaMajorasMask'' (where you have to use the Mirror Shield to store light in special mirrors and eventually direct them onto a sun target. For added difficulty, the light is only stored in the mirror for a limited time, so if you are too slow, you have to go back and start over again).
* The Hall of Learning area in ''VideoGame/PrinceOfPersiaTheSandsOfTime''. Another, smaller one occurs at the bottom of the Tower of Dawn.
* Demitel's castle in ''VideoGame/TalesOfPhantasia'' has a variant with prisms.
* Shows up in the Tower of Mana in ''VideoGame/TalesOfSymphonia''.
* This occurs throughout Woohoo Hooniversity in ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]''. The player never gets to directly manipulate the mirrors. Instead, they align themselves as you complete the SolveTheSoupCans puzzles.
* It appears twice in ''DungeonSiege II'': The first one is for the main quest, and the other is for a side quest (albeit an important one).
* There are a couple of these in ''DevilMayCry 3''. In a mild twist, you manipulate the light by smashing unnecessary mirrors with your sword.
* A version of this appears in ''Uncharted 2'' of the ''{{Uncharted}}'' series. Of course, like many aspects of that particular game, while mirrors are re focused, there is also an emphasis on platforming within the puzzle.
* The Luminous Labyrinth in ''VideoGame/SagaFrontier'' which characters must solve to obtain the gift of light magic. Uniquely, it also adds color filters into the mix. You have to hit the exit portal with a certain color of light to escape; hitting it with another color will either give you an item or start a random battle. Simply finding the right color for a single laser beam will open a safe in ''Safecracker''.
* ''VideoGame/RuneScape'' has a very large and very difficult 3D one. It's difficult partly because of its construction (even including multiple colors) and partly because the "Temple of Light" is full of monsters.
** Specifically, monsters that have low hp, high attack, and a high spawn rate, making there no good way to deal with them. If you ignore them they keep hurting you; if you fight them they keep coming back. And even if you're immune to damage with prayer, their attacks still automatically close all menus, meaning you have to click through the menus to rotate the mirror in the second or two between each attack. On the positive side, if you enter the mirror rotation menu before you draw aggro from a Shadow, it will be unable to attack you until you exit the window. This can be utilized to allow your life points and run energy to restore.
* Light and mirror puzzles appear many times in the ''NeverwinterNights'' RPG series.
* ''IcewindDale II'' has one in the Ice Temple.
* In the DS version of ''VideoGame/TheLegendOfSpyro: The Eternal Night'', you often come across puzzles like this which you must olve in order to unlock a new part of the level.
* ''VideoGame/DigitalDevilSaga'' had a few of these in one dungeon. Somewhat justified in this case, as they occur in an amusement park and they're implied to be part of the attraction. They're also much less annoying than most, since enemies don't appear in the rooms they're in.
* One of the {{Boss Battle}}s in ''ZackAndWiki''. [[spoiler:You sometimes need to place a mirror in the hands of the frozen rival captain as part of the sequence, so she can fill in for a broken pedestal.]]
* ''VideoGame/MediEvil2'' features a vampire boss who must be defeated with mirrors, both by directing sunlight at and by [[PlayingTennisWithTheBoss reflecting his attacks back at him]].
* In ''MegaManBattleNetwork 5'', you are in a room on a ship when the lights go out and a valuable program gets stolen. No one in the room has it. The open door, the mirrors and the fact that navis can travel on infrared beams are all important to solving the mystery. Answer: [[spoiler:It's Napalm Man or Tomahawk Man and their operators, depending on the version.]]
* ''VideoGame/MegaManXCommandMission'', on the other hand, had a more traditional puzzle version, with a bizarrely long series of rooms where you just redirected lasers all over the place. Just to make it more annoying, there was often an extra target that would trigger a battle every time you moved a mirror while the laser was pointed towards it. Furthermore, you also need to reflect each beam to a matching-colored object in each room to unlock the item crystals in the floor above, but there's no hint whatsoever you need to do this and once you do the above, there's isn't any kind of notification that you actually accomplished anything.
* ''VideoGame/{{Mega Man X}}6'' has one of these. About half of Shield Sheldon's stage is a LightAndMirrorsPuzzle. Hilariously enough, over half of it is ''entirely unnecessary'' to traverse: the boss is located one-third of the way through the level. The only reason for going through the entire level is to reach the extra "bonus" stage, and get some additional equipment for X.
* ''VideoGame/TombRaiderAnniversary'' has one of these, set in an Egyptian tomb.
* The game (loosely) based off Disney's ''The Haunted Mansion'' has one of these in the Moon Room. The goal is to bounce a beam of light into a "moonstone" by rotating a set of mirrors. Once the light hits the stone, it lights the entire room.
* ''[[VideoGame/{{Zork}} Beyond Zork]]'' had one of these in the endgame, making this ... Older Than Graphics. Fortunately (and atypically for text adventures), there's an onscreen map, which makes working out the correct angles and orientations for mirrors a lot less painful.
* ''VideoGame/BeyondGoodAndEvil'' has one of these it its [[TheVeryDefinitelyFinalDungeon final dungeon]]. The design of the room gives it a few shades of WombLevel, as well.
* ''VideoGame/TheDig'' has one of these.
* In ''VideoGame/KingsQuestVII'', Valanice must complete such a puzzle in the temple to get an important item: [[spoiler: half of the "key" that opens the door to the next section.]]
* The FanRemake of KingsQuestII has a minor one of these where you have to reflect sunlight through an anti-magic gemstone.
* ''VideoGame/{{Portal}}'' has a variation on this in that you must direct energy orbs into receptors that in turn open doors or power lifts etc. The orbs can be bounced off various surfaces, or teleported from one surface to another by the use of portals. The orbs can also be utilised to vaporise oneself if in an UnWinnable position, and push friendly turrets off platforms. Note that, unlike traditional beams of light, the orbs don't need a complete line-of-sight between emitter and receiver, making it a ''lot'' easier to get stuff done. They [[StuffBlowingUp explode]] harmlessly after a while, though, and a new one is supplied from the emitter again.
* VideoGame/{{Portal 2}} replaces them with [[FrickinLaserBeams Thermal Discouragement Beams]] and Discouragement Redirection Cubes.
* Some landscapes in the ''Oxyd'' series have these. The light however is a laser and can open passages by destroying walls. It can also destroy your marble and lose you a life if you're not careful.
* ''VideoGame/EternalDarkness'' has one of such puzzles twice: one with a diorama of a city that unlocks a door, and another with a telescope and mirrors that unlocks the path to the final boss.
* ''VideoGame/SonicAdventure'' used a variant on this in Lost World, where the object was simply to light your path, rather than hitting a target. In the UpdatedRerelease ''Sonic Adventure DX: Director's Cut'', this area is a little lighter. You can get through without doing the puzzle, though you can still do it anyway. Good thing too, because it's possible to get hit while you're turning the mirrors.
* ''VideoGame/HalfLife1: Opposing Force'' had a variant early on where rather than moving the mirrors you had to break one of them.
** Half-Life Decay included a laser and mirror puzzle.
* ''VideoGame/TheElderScrollsIVOblivion: The Shivering Isles'' includes a variation with rotating statues that shoot lightning. Angle the statues properly, and the last lightning bolt will blast down a wall, revealing a secret area. It's entirely optional, however.
* Three of these can be found in Vesplume Tower in ''InfiniteUndiscovery''.
* ''Franchise/ResidentEvil'' games tend to prefer the LaserHallway, but ''Resident Evil 4'' did have one instance of this on the island. ''VideoGame/ResidentEvil5'' does it again, this time several times in succession. And if you touch the beams, [[MalevolentArchitecture they KILL you.]]
* ''[[VideoGame/SilentHill4 Silent Hill 4: The Room]]'' features the infamous [[ThatOnePuzzle water prison puzzle]], which requires [[spoiler:rotating the circular floors of a tower on their axis so as to align four specific holes out of several possible, thus channeling the light from the roof all the way into the basement]]. After you do this once, you must [[spoiler:repeat the whole procedure, this time aligning four different holes over another part of the basement]]. While not terribly difficult to perform, the fact that it requires [[MoonLogicPuzzle improbable logic]] to figure it out usually leaves players stuck at this point.
* ''VideoGame/JadeEmpire'' features an insultingly easy light puzzle in the Great Southern Forest, involving focusing different colours of light through a lens in order to open a portal to another dimension.
* Similar to the ''VideoGame/JadeEmpire'' example, ''VideoGame/MassEffect2'' also has one of these in a side quest that's almost harder to find than the puzzle is to solve.
* ''VideoGame/TorinsPassage'' has one of these at the end of [[LethalLavaLand Aesthenia]], though it is presented as a Light And ''Prisms'' Puzzle.
* Some of the recent ''SpyroTheDragon'' games use these as a SolveTheSoupCans puzzle - you're even forced to [[FetchQuest collect the mirrors]] from around the area before starting the puzzle.
* A minor computer game called ''Hyperman'' had one of these puzzles needed to melt a block of ice and get a key item.
* Used a couple of times in ''VideoGame/NancyDrew'' games to activate mechanisms or open doors.
* The Robinson Crusoe segment of ''Azada 2'' requires you to connect several spots to one another with a single laser beam.
* Opening one of the tusks in ''VideoGame/{{Myst}} III: Exile'' requires you to bounce a beam of light all over the island, and also provides the combination for the door.
* A few of the puzzles in ''SoulReaver'' involve using mirrors to redirect beams of light, when they don't involve [[BlockPuzzle blocks]].
* ''VideoGame/DuckTales 2'' has an extremely simple one where a mirror only needs to be dragged to the left so it reflects the beam of sunlight which breaks the floor.
* The first dungeon in ''VideoGame/GoldenSun'' has a puzzle in which beams of light must be cast onto certain tiles to unlock a portal. The second game has another similar one in which you must open up holes in the ground so that beams of sunlight can hit mirrors that aim it at an extremely photosensitive boss, weakening it.
* ''VideoGame/{{Avernum}} III'' has several of the laser variety in the Golem Factory and the Concealed Passage. The puzzle is generally to put the mirrors in such an alignment that the lasers won't [[InsurmountableWaistHighFence block your path]], but you can also turn the lasers back on the laser generators and destroy them all to express your true feelings for these kind of puzzles. As an aside, this is one of the few places where the game was changed significantly from the earlier ''VideoGame/{{Exile}}'' series, which used conveyor belts in the equivalent dungeons -- these were deemed incompatible with the new engine.
* The final puzzle of ''VideoGame/{{Shivers}} 2'' involves opening up the MacGuffin talisman, an ancient Native American artifact, to find... a laser-and-mirror puzzle inside. The player can choose to avoid this puzzle, getting the second-best ending instead.
* The final puzzle of the IF game ''[[http://wurb.com/if/game/2163 The Erudition Chamber]]'' involves this.
* The platform game ''Challenge of the Ancient Empires!'', with the added twist that the light source is the bulb on your character's helmet, so the light beam must be shot from an appropriate location.
* Oddly subverted in ''VideoGame/DragonQuestIX'', where the mirrors were already in the correct positions and the player needed only to turn on the lights (as simple as walking up to them and pressing "on", no less).
* The Reflector in ''RatchetAndClankUpYourArsenal'' is normally used for these. Different from most other examples in that it incorporates a field that absorbs the beam, and an emitter that can be pointed anywhere.
* ''Darkest Fear'', a mobile phone game set in a hospital infested with light-fearing monsters, consists almost entirely of this.
* ''VideoGame/AssaultOnVampireIsland'' has a variation where you need to rotate the lamp of a lighthouse.
* ''VideoGame/EscapeFromStMarys'' does it, where the goal is to send the beam into a basketball player's eye.
* Feature in the Rube Goldberg Machines you're required to build in the flash game "Electric Box". Some levels even require you to use a mirror to reflect a laser to activate a device that will destroy the mirror so the laser can activate a second device. Only laser beams can be reflected, mirrors have no effect on the light from ordinary light bulbs.
* There's a series of these in ''VideoGame/ProfessorLaytonAndTheMiracleMask'''s daily downloadable puzzles where you have to position mirrors so colored rays of light will be reflected a certain number of times before they hit same-colored ghosts.
* One dungeon in ''VideoGame/TalesOfTheAbyss'' has a couple of oddly half-hearted light and mirror puzzles, as if the designers of the game felt obligated to include every possible type of block puzzle but couldn't be bothered to actually make it require effort. A straighter example can be found in the use of [[RidiculouslyCuteCritter Mieu's]] fireballs, which have to be reflected off things in the final dungeon and several sidequests as well.
* The remake of ''QuestForGloryII'' has a minigame called "Force Bolt Flurry," which can be played by anybody with magical skill and knowledge of the appropriate spells. It's pretty much a Light and Mirrors Puzzle with Force Bolts instead of light, and with the added challenge of preventing your opponent from reflecting his Force Bolts into your territory.
* In ''VideoGame/StrangeCasesTheTarotCardMystery'', the Attic level is one of these puzzles.
* Laser beams and mirror figure into many puzzles in ''VideoGame/{{Dweep}}''.
* One such puzzle appears at the beginning of ''VideoGame/TheBizarreAdventuresOfWoodruffAndTheSchnibble'', in the shop. You must position two mirrors so that they're able to correctly deflect a light beam and hit a nose, making it visible.
* Shows up a number of times in the ''VideoGame/{{Skylanders}}'' series. Sometimes you have to move other blocks out of the way, and sometimes, you need the laser to melt a block of ice so that it reveals yet another mirror.

[[folder: Film ]]

* In the film ''Film/{{Legend}}'', the heroes must reflect a beam of sunshine all the way down to the bottom of hell.
* ''Film/BatmanAndRobin'' had one of these, essentially. [[spoiler: Using orbiting mirrors to thaw a frozen Gotham city.]] A scene very early in the movie had the Bat-signal reflected by several mirrors until it was visible in Bruce's study. That movie might have been ridiculous overall, but in this one case, ChekhovsGun was clearly visible on the mantlepiece.
* While not a puzzle, ''The Mummy'' had the group enter a large, dim tomb. Evie angles a mirror on a stand to direct the sunlight above into several other mirrors positioned around the room, illuminating the room. The Series/MythBusters [[JustForFun/TropesExaminedByTheMythBusters tested]] this. While you can light a room this way, the constantly moving sun means it won't last long, and it is nowhere near the movie's level of light.
* A scene from ''Film/{{Brick}}'' has Brendan using a piece of a broken mirror to reflect a beam of sunlight into a basement.

[[folder: Live Action Television ]]

* An episode of ''The Magic School Bus'' revolves around this, a game of 'Light Pinball'. The objective is using mirrors and prisms to split a beam of light into the colours of the rainbow and redirect them into like-coloured eyes.
* ''Series/DoctorWho,'' "The Five Doctors": The First Doctor and his granddaughter Susan are in a building with reflective walls and a Dalek. They do something that includes sneaking up behind it, dropping to the floor, and by so doing maneuvering it to fire its death beam so the beam bounces off the mirrors and hits the Dalek. Something similar was used in the 2006 episode "Tooth and Claw," where a badly made telescope turns out to be designed to focus moonlight in some special way and then shine it through the Koh-i-Noor, which apparently [[BeethovenWasAnAlienSpy Prince Albert had cut specifically for this purpose]], to zap a werewolf-alien before it kills Queen Victoria.

* In ''Manga/CaseClosed'', such a puzzle is the key to unlocking a mechanism that reveals a hidden treasure in the house of an ex-robber gone legit.

* Gabe from PennyArcade did this in a tabletop game of Dungeons and Dragons, using a laser pointer and some 1'x1' art mirrors.
* In ''Webcomic/{{Homestuck}}'', there is a point-and-click Flash where Jane has to solve one by rotating a set of lanterns to reflect light off the mirrors on ancient obelisks to shine light into several deep pits.

* Setting up an [[http://en.wikipedia.org/wiki/Optical_table optical table]], or adding more lasers to one, can easily be this.
