The Big Book of Math Logic Puzzles

تفاصيل الكتاب

The Big Book of Math Logic Puzzles, by Elyas Oulma. Printed puzzle book in English. Read the edition details and check availability on Amazon.

Every puzzle in this book can be solved by pure logic — no guessing, ever. We test it. Ten deduction mechanics, ordered as a ramp: missing-brick pyramids, operator hunts, reverse number machines, cross math, four-op crosswords, big number fits, number locks, shape systems, logic grids and honeycomb rings. Every chapter opens with a solved example; the book opens with one promise, explained to the solver: if you're stuck, there is always a next step — find the cell that's forced. The Grand Mix finale shuffles all ten. • 200+ puzzles across 10 deduction mechanics — every one verified uniquely solvable • Chapters ramp from propagation warm-ups to pure-deduction capstones • Full solutions at the back, grouped by chapter • Big write-in cells, large print, one clean layout • Ages 10-13 · grades 5-8 · 100% screen-free Each chapter comes from a full series by the same author — and when the deduction habit sticks, the Kakuro Masters and Sudoku Masters Collections await.
