Slide your purple sticky block through increasingly fiendish levels in this strategy puzzle game. Other blocks stick to yours whether you want them to or not, so you need to plan your moves carefully or end up in the middle of a large, unmovable clump of blocks! Deliver blocks to identically-colored locks to clear up space and pass through to the next level.
Achieve a star rating on most levels by finishing the level with the indicated blocks stuck to your purple sticky block.
There are 50 regular levels, 8 bonus levels, and even some secret levels to discover.
