History Main / LightAndMirrorsPuzzle

* In ''VideoGame/LordOfTheRingsOnline'', a main quest and a group instance take place in the Mirror-halls of Lumul-nar in Moria. At a few stages in each level, the player(s) must use mirrors to direct a light beam to shrivel up webbing that covers the entrance to the next chamber.

* The ''VideoGame/{{Minecraft}}'' [[VideoGame/MinecraftAdventureMaps adventure map]] ''Diversity 2'' focuses on this sort of puzzle for the first half of the Adventure Branch. The twist is that the mirrors are hidden throughout a mansion, and you need to find all 8 of them to complete the puzzle.

%%* ''VideoGame/TheDig'' has one of these.

* In ''VideoGame/UnleashTheLight'', the Alien Moon has several puzzles where you have to direct the spotlight to the light-powered pyramid using reflective pillars. The arrows on the pillars indicate the direction the beam of light will take upon hitting them. Some of the puzzles require the beam to be of a certain color, and you have to combine the colored lights to get it.

* In ''VideoGame/UnleashTheLight'', the Alien Moon has several puzzles where you have to direct the spotlight to the light-powered pyramid using reflective pillars. The arrows on the pillars indicate the direction the beam of light will take upon hitting them.

* ''VideoGame/UnleashTheLight'': In the third stage of the Alien Moon, there's a pyramid that needs to be activated by light in one cave room and a pillar in another. You need to press and drag the pillar into the spotlight so it can shine a beam into the pyramid to open the next room.

* 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.

* A staple of ''[[VideoGame/TheRoomMobileGame The Room]]'' games, usually involving crystals as the source of light, or as prisms.

* ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'': One of the many Zonai devices in this game is a portable mirror that reflects sunlight as a beam. Some puzzles require you to use these mirrors to shine a beam of light onto a solar panel, usually to open a door. The Lightning Temple in particular makes heavy use of this kind of puzzle, including using mirrors attached to movable pillars in the central chamber to shine light between different floors.

** There's a Dwemer ruin where you need to focus multiple beams of light onto a central object. This is done by using the two most basic fire and frost spells to expand or contract the focusing crystals. You can also use the more advanced spells, but these will realign the beams to a much stronger degree, making the puzzle nearly impossible to figure out, and it can be quite a challenge even if approached the intended way.

* ''VideoGame/HalfLife1: Opposing Force'' had a variant early on where rather than moving the mirrors you had to break one of them.
** ''VideoGame/HalfLifeDecay'' included a laser and mirror puzzle.

* ''VideoGame/TheElderScrollsVSkyrim'' has this in the "Discerning the Transmundane" quest. You must orient a set of lenses to shine light on a massive dwarven sphere to gain access to [[spoiler:an Elder Scroll]], but in fact all you have to do is press the leftmost button repeatedly until the next one to the left becomes usable, and rinse and repeat until you are on the last button.

* ''VideoGame/{{Portal 2}}'' replaces them with [[EnergyWeapon Thermal Discouragement Beams]] and Discouragement Redirection Cubes.

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.

* ''VideoGame/TombRaider'':

* ''VideoGame/DragonQuestIX'' is a subversion, as the mirrors are already in the correct positions and the player needs only to turn on the lights (as simple as walking up to them and pressing "on", no less).

* ''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.

* There are a couple of these in ''VideoGame/DevilMayCry3''. In a mild twist, you manipulate the light by smashing unnecessary mirrors with your sword.

* 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.

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