In Portal, the player is challenged to navigate through a series of rooms using the portal gun. The portal gun can create two distinct portal ends, orange and blue. The portals create a visual and physical connection between two different locations in three-dimensional space. Neither end is specifically an entrance or exit; all objects that travel through one portal will exit through the other. An important aspect of the game's physics is momentum redirection. As moving objects pass through portals, they come through the exit portal at the same direction that the exit portal is facing and with the same speed with which they passed through the entrance portal. For example, a common maneuver is to jump down to a portal on the floor and emerge through a wall, flying over a gap or another obstacle. This allows the player to launch objects over great distances, both vertically and horizontally. If portal ends are not on parallel planes, the character passing through is reoriented to be upright with respect to gravity after leaving a portal end.

The player is sometimes provided with cubes that can pick up and use to climb on or to hold down large buttons that open doors or activate mechanisms.
Although the player is equipped with mechanized heel springs to prevent damage from falling,he can be killed by various other hazards in the test chambers, such as turret guns, bouncing balls of energy, and toxic liquid. He can also be killed by objects falling through portals, and by a series of crushers that appear in certain levels. Unlike most action games at the time, there is no health indicator. Some obstacles, such as the energy balls and crushing pistons, deal fatal damage with a single blow.
Portal was acclaimed as one of the most original games of 2007, despite being considered short in length.
