Kugel-Snap-Spiel

The board consists of a grid of 6x6 holes. In each hole is a colored ball. You must collect (according to version) all colors or 3 of the six. To collect, you press a construction in 3 adjacent holes (solo version: 4 holes) and you pick all the 3 (4) balls. If a hole is empty, you don't get a ball there of course.
