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:
A less common puzzle type for solvers who want something fresh beyond standard Sudoku and other familiar number puzzles. Progressive challenge with smaller puzzles at the beginning and larger, more demanding grids later in the book. Helpful sum-combination lists printed below each grid to support structured solving. One solution per puzzle so every result is earned through logic rather than guesswork. Deduction-based solving that rewards careful comparison of neighboring triangles and possible combinations.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.
