ReversiFun is a strategy board game that you play against your device on an 8x8 game board. There are 64 identical game pieces, each of which has a white side and a black side. You and your device take turns to place the game pieces with your assigned color facing up. In each turn, player must place a piece to bind a straight line of the opponents pieces with another existing piece, then these opponents pieces change to the current players color. The game ends when there are no more legal placements and the winner is the player that has more pieces on the board.
