All balls are distributed in the centre of the playing area (e.g. in vaulting box elements, hoops or on soft mats). The groups start behind their baseline and try to fill their depot (e.g. vault elements, tyres or soft mats) with balls after the start signal. Only one ball may be transported per run (if necessary, define the method of transporting the ball: carrying, bouncing, dribbling or rolling). Which group has collected more balls after a certain time?
Variant:
As soon as the supply of balls in the centre has been used up, balls can be stolen from the other team's storage area.
