Players divide into two or more equal-size columns on a starting line, with players separated by about three feet. The first player stands with his feet wide apart; the next bends over in leap-frog position. Positions alternate in this way, down each line. On signal, the last player in each line crawls under the legs of the player in front of him, vaults over the next player, crawls under the next and so on, until he has reached the head of the line. Then the player now at the foot of the line repeats the action, always starting by going under the player in front of him. Thus player alternate their positions, first standing up, and then bending over. The team that completes the action first-so all the players are back in their original places-wins.
