The ball is placed on the two bars at the bottom of the game, in front of the player. By pushing the bars towards each other with the handles, the ball is pushed upwards. A gentle movement in which the bars move slightly apart gives the ball a small push and it rolls upwards. At the moment that it has rolled the furthest, the bars are pulled completely apart, so that the ball falls into one of the compartments. In this way, a personal record can be built up or played against each other.

Benefits and skills practiced:
- Force regulation: The game requires the correct use of force to move the ball. This helps develop good motor skills and force control.
- Patience: The process is quite challenging and thus requires patience and perseverance.
- Two-handed coordination: Using both hands to move the bars helps improve coordination between the hands.
- Insight and Strategy: Players must develop insight into how the movements of the bars affect the movement of the ball, which helps develop strategic thinking.
So this game not only provides entertainment, but also a good way to practice and improve various motor and cognitive skills.

Playing tip: also a fun tool for open-ended play with other balls and marbles.
