Each player places atoms on the board during their turn.

When a cell reaches its limit, it explodes, spreading atoms to nearby cells and taking control of them.

This can trigger powerful chain reactions that spread across the board and eliminate your opponents.

Careful strategy, timing, and positioning are the key to victory.

Create massive reactions, control the board, and defeat every opponent.
