How to draw the rules of the game and the chessboard like lions, tigers, leopards, wolves, dogs, cats and mice played in primary schools when I was a child?

The order of the size of the pieces in the Colosseum is elephant, lion, tiger, leopard, dog, wolf, cat and mouse. Among them, mice can eat elephants, other chess pieces can eat small ones according to the big ones, and they can eat each other with the same size.

The chessboard in the Colosseum has seven rows horizontally and nine rows vertically, with two squares in the middle. Among them, lions and tigers can jump across the river and eat animals on the other side directly. Only mice can go into the water, and mice in the water can stop lions and tigers from jumping into the river. Two mice can eat each other in the water.

1, liger jump into the river method: There are two rivers on the chessboard. When liger crosses the river, he can jump vertically and horizontally, and he can also eat the enemy's smaller beasts in the jumping box, but if the mouse is in the river, he can't jump if he blocks the jumping route.

2, the mouse into the water method: the mouse can walk into the water when crossing the river (walking in the same way as land). If the mouse is in the river, the animals on the land can't eat it, and the mouse can't eat the elephants on the land. When two mice meet in Hanoi, they can eat each other.
