What can you do with an empty space? That one missing spot is what makes the whole puzzle move — slide, rotate, repeat.

A hands-busy, oddly satisfying puzzle that moves using one empty space.  This twin pack includes a small Level 1 puzzle (easy place to start + pocket-sized) and a larger Level 2 puzzle (more of a challenge). Great for waiting, listening, winding down, and anyone who loves a good pattern-y brain itch.
