Equipment
The chessboard has 9 straight lines and 10 horizontal lines, which form 90 points, and the chess pieces are placed on the points. It is divided into two sides by a river in the middle. At both ends of each side, a territory is formed by 3x3 straight lines and 4 diagonal lines.
There are 32 chess pieces, divided into two sides: red and black. Each side contains 1 elephant, 2 lions, 2 tigers, 2 leopards, 2 wolves, 2 monkeys, and 5 rats.

Movement
*The Elephant can move one point vertically or horizontally, but not diagonally. It is confined to the territory.
*The Lion moves one point diagonally. It is also confined to the territory, like the Elephant.
*The Tiger moves two points in any diagonal direction and cannot jump over the middle piece. It can only move on its own side and cannot cross the river
*The Leopard can move any number of points horizontally or vertically. It cannot jump over pieces on its path.
*The Wolf moves one point horizontally or vertically, and then one point diagonally. It cannot move in a direction if there is an object in its path blocking it.
*The Monkey can move any number of points horizontally or vertically. To capture, the Monkey must jump over a chess piece, whether friend or foe, along its path of movement.
*The Rat moves and captures by pushing forward one point. Once the rat crosses the river, it may also move horizontally and capture one point. The rat may never back away, thereby retreating.

Rules
*The player with the red pieces always makes the first move, and then the next player goes.
