The Moscow Puzzles: 359 Mathematical Recreations

My grandfather had this exact edition when I was a kid, and flipping through these 359 recreations brings back that same musty-paper smell of his study. The range is incredible, from simple arithmetic tricks to geometry puzzles that still stump me after an hour of doodling.

My grandfather had a worn copy of this and I finally tracked down my own — the 359 problems are exactly as clever as he always said, and the decades-old Soviet puzzle logic still feels fresh today. The translation reads smoothly, so nothing gets lost in the math.

I've had this book for three weeks and I'm only a third of the way through, because each puzzle makes me stop and actually think. The range is incredible—from simple logic tricks to ones that still have me sketching diagrams at 2 a.m. It's the kind of collection that makes you feel clever one minute
