Flip chess, also known as Reversi, Apple chess or Othello, is a two-player chess game.
According to the rules of the game described in Wikipedia: the board has 8 rows and 8 columns, a total of 64 cells. At the start of the game, 4 black and white chess pieces are placed in the 4 squares in the center of the chessboard (there are also changes to place them adjacently). Usually the black ones go first. Both sides take turns making moves. As long as the placed piece is sandwiched between the opponent's piece and any of your own pieces on the board (horizontal, straight, or diagonal), you can turn the opponent's pieces into your own (just flip them over). Every move a player makes must flip at least one piece according to the above rules. If there are no moves to make, the player must give up. When both sides have no moves to make, the game ends, and the side with the most colored chess pieces is the winner.
Remember: gold horns, silver edges, stinky bellies.
This game is a brain exercise and fun.
