Rules of the game

Play!

1. The game is played on a board consisting of several (initially empty) cells.
2. Every player has a distinct color.
3. Players take turns; each turn, a player must place an atom of his color to the game board.
4. Atoms can be placed either to an empty cell, or to a cell which already contains your color.
5. Every cell can contain a maximum of atoms equal to the number of its neighbors (4-side neighborhood).
6. When the amount of atoms in a cell exceeds that cell's maximum, the cell explodes: one atom jumps to every neighbor.
7. Jumping atoms instantly re-color all atoms in target cell to their own color.
8. Player owning all cells on the board wins.
