Reversi/othello/reversi

This is a unique 8×8 Reversi, also known as othello or reversi. Reversi is a classic chess game full of strategic fun. The game is played on an 8×8 square chessboard, and both sides hold black and white pieces respectively. At the beginning, four squares in the very center of the chessboard are placed with two black and two white pieces crosswise.Both sides take turns to place pieces on the chessboard. The rule for placement is that the newly placed piece must sandwich the opponent's pieces. The so - called "sandwich" means that, in the horizontal, vertical or diagonal direction of the chessboard, between the newly placed piece of one's own side and the existing pieces of one's own side, the opponent's pieces are in between them, and there are no blank squares in this direction anymore. When one side finishes placing a piece, the sandwiched opponent's pieces will be flipped to the color of one's own side.Moreover, our unique model is even more ingenious.
