The Board
The 3x3 board contains cells. Each cell may have 0 or more pieces in them.
The Pieces
Two different colored pieces.
Rules
To move: Place a piece into an open box that does not have the opponent's color.
To win: Completely remove all of your opponent's pieces.
Players alternate turns placing pieces into any box or cell that does not contain the opponent's color.
If the cell or box becomes greater than or equal to the number of adjacent cells, then the cell will explode. When this occurs all the pieces in the box are removed except for one. The remaining pieces are distributed to each adjacent box and each box becomes the color of the player who caused the explosion.
Variants
- Misere: If you place your piece into an open box that does not have your opponent's piece you lose.
- Board Size: Vary the size of the board.
