"The Room" and its sequels are puzzle games released for iOS and Android by Fireproof Games.
The games are played from a first-person perspective, with the player able to freely rotate the camera and zoom in and out on objects. The user can interact with objects when zoomed in using the touch-screen, e.g. to flick a switch or rotate a handle. A key element is an eyepiece which, when selected allows the player to view items or objects which are otherwise invisible or hidden inside other objects.
The gameplay revolves around investigating and manipulating objects in a room. For example there may be a box on a table in the room. Investigating the box, possibly using the eyepiece, may indicate a sliding panel which reveals a keyhole. Investigating the table legs may find a section which rotates to reveal the key. Using the key in the hole may cause a section of the box to fold out revealing a further puzzle to solve.
The story is told through reading notes found around the objects, charting the story of a researcher who came before you. Repeated symbols of power give a Lovecraftian feel.
Many puzzles are of the "find an object, fit it in the correct slot" type, and in this way the games can be seen as an evolution of the classic point and click adventure. However there are a wide variety of other puzzles, including mazes, "Simon" style repetition games, and many others. The puzzles are not particularly taxing, and a generous help system means that the user will never be stuck for long. Much of the entertainment therefore comes from the environments and the intricate interactions as each puzzle solved causes changes to the objects in the room.
