Best Math Puzzle Books for Middle School (Sudoku, KenKen, and More)

April 5, 2026 · 7 min read · By Infinilearn Team

Math puzzle books are an underrated tool for middle school math practice. They're screen-free, portable, work without WiFi, and engage the brain in the same way that crossword puzzles engage word lovers. For students who like puzzles, a good math puzzle book can produce more voluntary practice than any worksheet — and the practice transfers to school math more than most parents realize.

Best Math Puzzle Books

Sudoku Puzzle Books

Sudoku isn't directly math, but it builds logical reasoning and pattern recognition that transfer to mathematical thinking. Start with easy puzzles and progress to medium and hard. A 100-puzzle book provides hours of focused logic practice.

KenKen Puzzles

KenKen is sudoku with arithmetic operations. Each "cage" has a target number and an operation. Students fill in digits that produce the target using that operation. KenKen books practice arithmetic AND logical reasoning simultaneously. Will Shortz publishes excellent KenKen books at multiple difficulty levels.

The Moscow Puzzles by Boris Kordemsky

A classic collection of mathematical puzzles from Russia. Many are accessible to middle schoolers and develop creative problem-solving skills that go beyond standard curriculum. The puzzles range from simple to genuinely challenging.

Brilliant Puzzles and Mathematical Recreations Series

Martin Gardner's mathematical recreations books are legendary in math education. They introduce students to topics they'd never see in school: probability paradoxes, geometric oddities, number theory curiosities. Many puzzles are accessible to bright middle schoolers.

Math Olympiad Contest Problems

Books of past Math Olympiad problems (MOEMS, AMC 8, MATHCOUNTS) provide extreme math challenges. For a student looking to push themselves, these problems develop problem-solving skills that standard curriculum doesn't.

Why Puzzle Books Work

  • Voluntary engagement. Students choose to do puzzles because they're inherently interesting — not because someone assigned them. This intrinsic motivation produces better learning than forced practice.
  • Screen-free. In a world of constant screens, puzzle books provide a different kind of focused attention. Many students find puzzle books relaxing in a way digital practice isn't.
  • Portable. Take a puzzle book on a plane, in the car, to a doctor's office. Math practice happens during what would otherwise be wasted time.
  • Builds problem-solving stamina. Puzzles often require sustained thinking — 5, 10, even 30 minutes on a single problem. This builds mathematical patience that transfers to test situations.

Combining Books with Digital Practice

The best math practice approach uses both. Puzzle books provide the screen-free, voluntary, problem-solving practice. Digital tools like Infinilearn provide the adaptive, standards-aligned, fluency-building practice. Together, they cover everything. The parent dashboard tracks the digital practice; the puzzle books speak for themselves.

The Bottom Line

Math puzzle books are screen-free, portable, voluntary practice. Sudoku, KenKen, classic puzzle collections, and competition problem books all develop mathematical thinking in formats that engage students who resist traditional practice. Buy a puzzle book, leave it on the kitchen table, and watch what happens.
