Description
The game consists of box, lid and 20 puzzle pieces. The lid has a small bump on the side that snaps into the box.
The puzzle pieces are used on both sides.
Although there are more than a million different solutions (not counting symmetric solutions), the puzzle is not easy to solve.
The size of the sliding top is crucial. If it's too narrow, the bumps on the top won't snap into place. If it's too wide, the top can usually still be inserted, but it becomes difficult to open.
If the top doesn't fit, it is advisable to adjust its dimensions in the slicer and reprint it. Recommended adjustments are only small increments ranging between approximately 0.2mm and 0.3mm in width (only in width).
