The players alternatelly put their pieces on the board.
You can put a piece on an empty square to enclose one or more of your opponents pieces between your pieces and the
piece you want to put down.
All the enclosed pieces of your opponent will turn their color and be yours.
If a player can not make a valid move, then the other player continues to play.
The winner is the player, who ends with the most pieces of his color on the board.
