Click on a square to reduce or increase its value, but be careful: it also affects its neighbors.
Challenge yourself in the Campaign across 75 handcrafted boards of increasing complexity. Plan each move, chain reactions, and empty out every grid!
Remember: you have a limited amount of moves per board: undo and reset are your friends.
Create your own boards via the Creation Center, share them, and play other players' boards via Share Codes.
And when you're finished with the campaign, play as much as you want with the Random Boards Generator.
