Synopsis

Experience the Original: 150 TriDoku Puzzles in a Triangular Grid

Refresh your passion for logic with the first-ever collection of TriDoku. If you are tired of standard 3x3 grids, this book introduces a revolutionary triangular architecture that will sharpen your existing skills and force you to learn entirely new solving techniques. Each puzzle is played on a massive triangular grid where nonets are triangles rather than squares, creating a sophisticated mental workout.

The Unique Rules of TriDoku

TriDoku abandons traditional rows and columns in favor of geometric complexity. To solve these grids, you must master several unique constraints:

  • Triangular Nonets: Each of the nine large triangles (drawn with thick lines) must contain all numbers from 1 to 9.
  • Outer and Inner Edges: The three sides of the large "big" triangle and the three sides of the "inner" triangle must each contain the digits 1 to 9 without repeats.
  • The Touching Rule: No two cells that touch—even by a single angle—can contain the same number. A single cell can touch up to 12 adjacent cells, allowing for rapid elimination of candidates.
  • The Hexagon Rule: Any six cells forming a hexagon must contain unique digits, providing a powerful secondary deductive tool.
Professional Challenge & Variety

This landmark first edition features 150 puzzles that escalate in complexity, including two elite variants for the advanced solver:

  • 10 TriDoku Star (TriDoku X): Features three additional lines where numbers cannot repeat, similar to Diagonal Sudoku.
  • 10 Killer TriDoku: The ultimate "beast" of the collection, replacing clues with cages and sums for a deeply satisfying arithmetic challenge.
Expertly Crafted by Djape
