PaintCan is an addictive puzzle game where you try and find an efficient sequence of steps to turn the entire grid the same colour. Use your moves wisely as there are only a limited number of them. Finishing each grid with as few moves as possible yields additional bonuses that allow you to keep playing further.

Two modes of play are offered: untimed and timed. In untimed mode, you are given an unlimited amount of time to ponder your moves, but there is a limit on the number of moves available to you. Additional moves are added based on how you complete each grid. In timed mode, you have a finite amount of time in which to complete as many boards as possible. Additional time is added as you complete each grid.
