Reversi

Reversi is a turn-based strategy game invented at the end of the 19th century. Two players called Dark (black) and Light (white). Each player puts one piece per turn on the board. The piece must be put on a space so that it sandwiches one or more of the opponent's lines (diagonal or vertical). The sandwiched disks are flipped to the color of the current player. If a player can not play, he must pass his turn. The classic board is a 8x8 grid. The application includes variants with different board sizes and shapes.
