Finally a Sudoku program that also handles 16 x 16 sudokus. I like the interface by Andrea Arevalo better however (sorry guys), because it is closer to the way you would make a sudoku on paper. I also feel it is much more powerful to only write in those numbers where there are e.g. no more than 2 cells in a square of three that could have a particular number. It is part of the art of making a Sudoku.

This is just awesome! It makes Sudoku so much easier for me! Simple but nice and clear interface. Thank you very much!

This is a great stuff. By this I can solve even the evil sudoku in small time.Thanks.

ptlboi & Everman - Look for "Pltboi Option" in Preferences,(2.3).
Icarus - You're right, I'll save that glassy button for later.
Eric L - I think a minimize button would be great, I'll work on it.
Geo Atreides - No can do on the Undo, but I'll think about the stats thing.

I would agree that it would be great to just have the squares blank at first. Then when you click on it you would be able to add your own possibilities.
