The player may pass the ball once to his teammate who can hit the ball on the wackitbase.
This pass helps to bring the ball closer to the centre where the wackitbase is positioned.
IMPORTANT:Passing the ball this way must be done with a bouncepass. So the ball must bounce on the floor before your teammate may hit the ball.
Passing the ball is allowed but is not mandatory. So if a teammember can hit the ball directly back on the wackitbase after a service or during a rally, than that is fine.
