What is the experimental principle of board games?

The movement of body center of gravity and the strength of leg muscles. The checkers game is to move the body center of gravity forward, then use the strength of leg muscles to jump up, then move the body center of gravity forward, and finally land on the target board. The principle of this experiment lies in the movement of body center of gravity and the strength of leg muscles. Only when the two are in harmony can we complete the skipping. Checkers is not only a children's game, but also an exercise to exercise physical coordination and muscle strength, which can promote physical health.
