Portal is a first-person puzzle-platform video game developed and published by Valve Corporation. Portal was released in a bundle package called The Orange Box for Microsoft Windows and Xbox 360 in October 2007, the PlayStation 3 in December 2007,OS X in May 2010, a Linux version in June 2013, and for Android as a port for the Nvidia Shield in May 2014.

The game consists primarily of a series of puzzles that must be solved by teleporting the player's character and simple objects using "the Aperture Science Handheld Portal Device", a device that can create inter-spatial portals between two flat planes. The player-character, Chell, is challenged and taunted by an artificial intelligence named GLaDOS (Genetic Lifeform and Disk Operating System) to complete each puzzle in the Aperture Science Enrichment Center using the portal gun with the promise of receiving cake when all the puzzles are completed. The game's unique physics allows momentum to be retained through portals, requiring creative use of portals to maneuver through the test chambers. This gameplay element is based on a similar concept from the game Narbacular Drop; many of the team members from the DigiPen Institute of Technology who worked on Narbacular Drop were hired by Valve for the creation of Portal, making it a spiritual successor to the game.
