A puzzle based on the aperiodic “spectre” monotile found by David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss.
I manufactured a small number of these puzzles for friends and family. If you have one, I hope you enjoy it!
Start by assembling the dodecagonal border and then fill it in with the 56 tiles. The border and all of the tiles should be placed smooth side up.
