I have been looking for months for a decent suduko game for mac. I have one on my pc and can solve very hard puzzles in 15 minutes or less just because the pencil marks are easy to enter. All I have found are complex time consuming methods of entering pencil marks on mac suduko puzzles. The pc suduko allows me to select a number and then go to all of the squares where that number is a possibility and then just click. It keeps the numbers in sequence from low to high. It does not position the numbers in the same place each time except for #1. It allows as many numbers as there are possibilities for the box even if the puzzle is a 16x16. The only thing the program does not allow is a dubbed puzzle except for a 9x9. I can create puzzles from 4x4 to 4x6 to 8x8 15x15 with the boxes being 3x5 each or in case of 16x16 it can have boxes of 2x8 8 across and 2 rows or 8 rows by 2 columns.
