Food Chain

1. Both sides of the game control their own eight pieces of "like lion, tiger, leopard, dog, wolf, cat and mouse";

2. According to the size relationship: A. elephant > lion > tiger > leopard > dog > wolf > cat; b. Lion > tiger > leopard > dog > wolf > cat > mouse; c. Rats > elephants can eat chess pieces smaller than themselves;

3. Finally, when there is only one piece left on the chessboard, the game ends and the remaining pieces win. When there are only one 4 or more pieces left on both sides, the "larger" side of the remaining pieces wins;

5. Each player is limited to 30 seconds for each move, and the overtime is judged as negative. Within the time range, players can choose to open a "closed" chess piece or move their own "open" chess piece.
