Description
Hashtag – Intermediate Sliding / Take Apart Puzzle
Hashtag is a cast-metal sliding take-apart puzzle designed by Yoshiyuki Kotani and Kirill Grebnev and produced by Hanayama. Four plate-like pieces overlap in a balanced arrangement, with each part affecting the movement of the others.
Work the plates apart, then rebuild their original arrangement. The visible straight-line movement provides the starting point, but making sense of how the pieces interfere with one another is the real task.
