R3v3rsi

R3v3rsi is a strategy game for two players.
There are many disks which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up.
During a move, any disks of the opponents color that are in a straight line (horizontal, vertical and diagonal) and are bounded by the disk just placed and another disk of the current players color are turned over to the current players color.
The player which ends the game with the more disks of his color win the game.
If a player cannot bound any opponent disks with his move, he has to pass the turn.
