Sukaku is an interesting variant of Sudoku. Rather than the standard format of revealing a few known numbers, you are instead given pencilmarks. As a matter of fact, another name for this puzzle is Pencilmark Sudoku. Otherwise, normal Sudoku rules apply. Fill the grid with 1-9 in such a way that no row, column, or 3×3 region contains a duplicate.
Season’s greetings! Today, we have a Tridoku puzzle. In this Sudoku variation, fill in each large triangle with the numbers 1-9 with no repeats. Also, you may not use duplicates in the legs of the highlighted outer or inner triangles.
