Klax

Klax is a 1990 puzzle video game developed and published by Atari Games for arcades; in Japan, it was distributed by Namco. The game was designed and animated by Mark Stephen Pierce, with software engineering by Dave Akers. The object of the game is to catch colored tiles moving down a conveyor belt, and arrange them in matching rows and patterns to make them disappear. Klax was originally released in February 1990 as an arcade follow-up to Tetris (1989), about which Atari Games had been in a legal dispute. It was later ported to several home and handheld systems, including the Nintendo Entertainment System, Genesis, Master System, TurboGrafx-16, Game Boy, and Lynx.
