Emily E. ★★★★★

It's rare to find a puzzle book that actually makes you groan and smile at the same time, but this selection from the old Cyclopedia nails it. The famous 14–15 puzzle alone is worth the price, and the trickiness of the other entries keeps me flipping pages every night.

Amelia W. ★★★★★

The trickiness is exactly what I wanted—every puzzle makes you think you've got it, then pulls the rug out. The 14–15 puzzle alone kept me busy for an entire evening, and the whimsy in the selection is unmatched.

Emma G. ★★★★★

I’ve been scratching my head over the 14-15 puzzle for hours, and the sheer trickiness of it is just delightful. The selection from the Cyclopedia feels like a hidden gem, full of bizarre originality that keeps me coming back for more.
