How to play

Blocks alternate between two horizontal directions. Tap the board or use the Place block button when the block lines up. The overhanging part is cut away. A nearly aligned block snaps into place.

Controls

Use touch or a mouse. Keyboard controls appear inside games that support them.

About your score

Each placed block earns 1 point; the base is excluded. No overlap ends the game. There is no final height. The speed increases as the tower grows.
