This puzzle is a level 10 sequential movement puzzle. The goal is to allow an internal ball to move through the puzzle, following the arrows, until ultimately it can escape out of the puzzle. This can be accomplished by manipulating the dials. The puzzle is not ‘blind’, as it allows you to see your progress through each set of dials.

The size of the puzzle is 1-3/4” x 4-1/2” x 4-5/8”, (45mm x 114mm x 117mm).
