Randomly, chose the child that will occupy the center hoop.
The 4 players not drawn take place on the 4 corners and the player picked settles on the center hoop.
At the signal of the player in the center, all players change places and the player in the center tries to steal a corner. The one who finds himself without a “corner” has lost and places himself in the center.
The players do it again.
You can complicate the game by keeping count per player, the final winner being the one who has found himself the least often in the center.
