An invisible wall or invisi-wall is a video game term for a boundary that limits where a player can go in a certain area, but doesn't appear in-game as any kind of visible obstacle, or as an obstacle that in reality could easily be bypassed, such as a mid-sized rock or short fence. In 2D games, the edge of the screen itself can form an "invisible wall", in that a character in play may be prevented from travelling off the edge of the screen. In 3D games, invisible walls are used similarly to prevent a player leaving the gameplay area. This is often done in preference to using a more visible boundary, as this can reduce the realism of the environment.

“It is hard going to the door
cut so small in the wall where
the vision which echoes loneliness
brings a scent of wild flowers in the wood.”
—Robert Creeley (b. 1926)
