Xiangqi: Chinese chess, duel

The game is played on a rectangular board of 9 by 10 lines. The shapes are set at the intersections of the lines. There is a river between the two central horizontal lines, which affects the movement of pawns, knights and bishops. The two areas marked by two diagonal lines of 3-by-3 squares are called palaces. Kings and advisors cannot leave these squares. The first move is made by the red pieces.
The game can be played with artificial intelligence, together with another person on the same device, or with a rival online in multiplayer mode. You can also watch other players' games, act as a spectator, and offer your own version of the player's next move by making it on the board.
