Instructions:

Bounce the balls with the help of the paddle. The paddle has 4 (prime) numbers on it, while the falling balls have numbers composed out of the ones on the paddle. If the number on the paddle divides the one on the ball, the ball gets smaller and you earn points. On the other hand, if the ball falls, you lose energy. Once the energy reaches 0, it’s Game Over. When a ball reaches 1, and thus cannot longer be divided, you can safely let it go.
