TriDoku: 150 Triangular Sudoku Puzzles

Is this Sudoku? Well... YES! ...and NO! <br/> 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. <br/> The “nonets’ are there, but instead of being 3x3 squares, they‘ve become triangles, too. <br/> Oh, and did you know that in Tridoku puzzles there are also lots of hexagons? <br/> However, despite all those differences, the basic principle of Sudoku still applies: you cannot repeat a number in any of the defined regions. <br/> It’s a lot of fun and a chance to develop new problem solving skills! <br/> ENJOY!
