Brix is a puzzle video game for MS-DOS, developed by Michael Riedel and produced and published in 1991.

[2] Brix presents the player with an array of square puzzle pieces that can be moved horizontally across the playing area.

As the player progress through the game's 112 levels, Brix adds more challenging gameplay elements, including lasers, reversing gravity, teleporters, elevators, breakable barriers and acid.

[citation needed] Computer Gaming World in 1994 said that Brix was "somewhat more interesting than the average brain teaser".

The magazine concluded that it was "an entertaining little exercise, although its potential for desktop-based addiction is not quite as high as its package would lead you to believe".
