"Beans" are virtual progress points in the game; they cannot be bought, sold, transferred between players, exchanged, or withdrawn for real money, and do not generate valuable rewards outside the game. There are no real money bets or participation fees, and beans cannot be transferred between two players. Each round starts with a fixed deduction of 5 beans from each player; the winner receives 9 beans generated by the system.

Step onto the chessboard, reveal your mystery pieces, and test your skills against players from all over the world.
