Play Klustar Online
You rotate your block cluster to absorb incoming pieces, desperately trying to form squares that collapse in big, satisfying chain reactions before everything spirals out of control.

Klustar came out in 1999 for the Game Boy Color, developed by Rebellion. It was part of that wave of puzzle games that tried to do something a little different on the handheld, moving beyond simple line clearing into more spatial territory.
You control a cluster of blocks in the center of the screen, rotating it to catch falling pieces. The goal is to form solid squares of a single color; completing one makes it vanish, often triggering a chain reaction. The real challenge is managing the constant influx of new pieces while your cluster grows and becomes harder to maneuver. It starts calmly but builds into a tense race against the inevitable pile-up. The feeling is one of frantic, geometric problem-solving, where a single good move can save you from disaster.
