Stella F. ★★★★★

Turning the square into a decagon took me nearly twenty minutes the first time, and I actually cheered when the last piece clicked into place. The pieces are cut cleanly enough that the decagon comes out perfectly even, no gaps. Great little desk puzzle for anyone who likes a real challenge.

Steven ★★★★★

The heft of the wood pieces feels great in the hand, and the square-to-decagon conversion took me a solid 20 minutes the first time. Now I keep it on my desk and race myself to see if I can flip the same pieces into the decagon without peeking.

Sophia ★★★★★

I left this on my coffee table and my brother-in-law grabbed it before dinner, then spent twenty minutes trying to turn the square into the decagon. The pieces fit together with a satisfying click and the wood grain makes it look nicer than the plastic puzzles I've had before.
