Portal is a single-player first-person action/puzzle video game. The game was released in the bundle package The Orange Box for Microsoft Windows and Xbox 360 on October 9, 2007, and for the PlayStation 3 on December 11, 2007. The Windows version of the game is also available for download separately through Valve's content delivery system, Steam, and was released as a standalone retail product on April 9, 2008.

The game consists primarily of a series of puzzles that must be solved by teleporting the player's character and other simple objects using the Aperture Science Handheld Portal Device, a unit that can create an inter-spatial portal between flat planes. The player character is challenged by an AI named "GLaDOS" to complete each puzzle in the "Aperture Science Computer-Aided Enrichment Center" using the Portal Gun. The unusual physics allowed by the portal gun are the emphasis of this game.
