19 moves. Size: 2 1/8" x 3" x 3"
Made of maple, ebony, ziricote and brass.

This puzzle box design is what I call a phrase puzzle. It is a sequential movement puzzle where the sequence is designed from a phrase. The sequence is basically like a maze where there is a start and finish with a few dead end paths along the way. 19 moves is all it takes to open this box, but it may take quite a bit more to actually get the box lid to come off.

This is the remaining one of six that were made for the IPP design competition of 2009.
