Players take on the role of blocks on a grid, bumping into each other in a rhythmic pattern to gain points. Each player's goal is to bump into the other blocks in a way that allows them to survive, while avoiding being hit.
The game requires timing and spatial reasoning as players control the movement of their block to meet the inbound blocks exactly, creating chains of reactions to earn high scores. The game runs directly in a web browser and can be played without a download or registration required.
