Hidoku is not Sudoku. It's a brand new puzzle game, played on a square or rectangle of any size. Your goal is to fill in the missing numbers from 1 to the maximum number (which is circled) by following one simple rule: consecutive numbers must touch each other either horizontally or vertically or diagonally. In this book there are 150 of these puzzles, which are all solvable by logic and no guessing is ever required.

Is this Sudoku? Well... YES ...and NO TriDoku puzzles have the same number of cells as Sudoku: 81. However, there are no rows or columns Instead, there are triangles. In fact, the whole grid has gone triangular. The "nonets' are there, but instead of being 3x3 squares, they've become triangles, too. Oh, and did you know that in Tridoku puzzles there are also lots of hexagons? However, despite all those differences, the basic principle of Sudoku still applies: you cannot repeat a number in any of the defined regions. It's a lot of fun and a chance to develop new problem solving skills ENJOY
