Chain Reaction is played on an 8 by 8 board. Players take turns to move.
On each move, the player may select an empty square, or one they already
own. Squares belonging to other players may not be chosen. If the square
was unowned, it becomes the property of the player, and is given a value of
1. If the square was owned by the player, the value is incremented.
If the value of a square ever exceeds the maximum permitted of that
square, it explodes. Squares in the corner have a maximum of 1, squares
touching an edge, but not on a corner have a maximum of 2, and squares in
the interior have a maximum of 3.
When a square explodes, it becomes unowned, and it's value is reset to
0. The 4 squares touching it become owned by the owner of the exploding
square, and their values are incremented. If any of these are above their
maximum, they explode, giving rise to the chain reaction.
If, at the end of a move, any of the players have no squares, they are
dead, and get no more turns. When there is only one person left, they are
the winner.
