Easy challenges: Rotate the game board to the right orientation, so that the position of the vertical ribs on the game board matches what is shown in each challenge. Note the orientation is always the same for the early, easier challenges.
Difficult challenges: The orientation of the game board is not shown in the challenge! Finding the position of the vertical ribs is part of the challenge. Therefore the orientation of the game board can be different for every challenge.
1) Choose a challenge from the booklet. Place the puzzle pieces on the game board as shown in the challenge. Puzzle pieces are made of balls of different sizes. The biggest balls only fit on the outer side of the game board. The smallest balls only fit on the central part of the game board.
2) Fit ALL the remaining pieces on the game board. Puzzle pieces cannot overlap the vertical ribs on the game board. All pieces are double sided and either side can be used.
3) There is only one solution for each challenge, which can be found at the end of the challenge booklet.
