Is this Sudoku? Well... YES! ...and NO!TriDoku puzzles have the same number ofcells as Sudoku: 81. However, there are norows or columns! Instead, there are triangles.In fact, the whole grid has gone triangular.The "nonets' are there, but instead of being3x3 squares, they've become triangles, too.Oh, and did you know that in Tridoku puzzlesthere are also lots of hexagons?However, despite all those differences, thebasic principle of Sudoku still applies: you cannot repeat a number in any of thedefined regions.It's a lot of fun and a chance to developnew problem solving skills!ENJOY!
