If you enjoy number puzzles but want something beyond the usual formats, this collection offers a distinctive and rewarding alternative. Trigons are not Sudoku—they are triangle-based number logic puzzles that require patience, analysis, and careful deduction.
Your goal is to place digits on the sides of each triangle so that they add up to the sum shown in the center. Possible sum combinations are listed below each grid, giving you a practical tool to narrow down options and solve each puzzle logically.
What makes this book different:
This collection is especially well suited to puzzle fans who enjoy discovering unusual numerical formats and learning a new solving system. Once you understand the rules, Trigons become a satisfying test of logic, elimination, and pattern recognition.
If you are looking for a puzzle book that feels genuinely different from standard grid-based logic books, this Trigons collection offers a distinctive challenge and a strong change of pace.
