Customer Reviews (4.3 / 5 · 3 reviews)

Ryan J. ★★★★★

Bending and twisting this thing through the challenge cards is strangely addictive — I lost track of time trying to solve just three. The patterns really force you to think in new ways, and the hinge mechanism moves surprisingly smoothly.

Ellie V. ★★★★☆

The challenge cards really make you think in new ways, and the hinge folds smoothly. Took me a few tries to get the first pattern right, but it’s satisfying once you do.

Madison N. ★★★★☆

The hinge mechanism itself is surprisingly smooth and satisfying to manipulate. I wish the challenge cards were a bit thicker, as they've already started to show some wear. Still, it's a clever little brain teaser that kept me occupied for a good while.
