When jumping, first put a stone or a disk made of coarse tiles (also sandbags) on the first side, and the jumper focuses one foot on the stone.
Gently kick into the first square, then jump into the first square with one foot, and kick the stone into the second square with the supporting foot. Go on in turn until the stones are kicked all over the squares.
If you are tired on the way, you can rest in the stipulated "old nest" box. If someone is kicking, the stone is pressed on the line, not on the line, or the stone passes through two squares.
Phenomenon, the calculation fails once, and the next round jumps from the first grid. The first person to reach the finish line should put the stone on the instep and walk out of the box gently. Finish everything first.
The actor wins, and the loser is punished by the winner.
