For all flavours of 32-bit Windows.
* Can solve puzzles completely automatically if you wish, and copy the result to the clipboard ready for pasting into those competition entry emails.
* It solves using exactly the same techniques that a human would. Only if this doesn't result in a solution does it resort to brute-force trial-and-error, and you can selectively disable this, or any other, solving technique.
* When solving automatically, it can create a log that shows the reason for entering each number in each cell, and the logic that allows for elimination of cell candidates.
* If a puzzle has multiple solutions, it can determine how many there are, and then show them to you.
* Can show the allowed entry "pencil-marks" for each cell.
* It can automatically update the pencil-marks as you enter numbers. This removes the tedium, but leaves the fun!
* Can prevent and/or highlight invalid entries.
* Can show the limitations imposed by the numbers already entered.
* When pasting from the clipboard, it will accept a wide variety of styles. This is extremely useful if you want to copy from discussion forums, websites etc.
* It can print the puzzle, optionally including pencil-marks, enabling you to solve away from your computer if you prefer.
* You can associate sudoku puzzle files, so that double-clicking one will automatically open it in Sudoku
* You can drag Sudoku puzzle files from Windows Explorer and drop them onto Sudoku.
* Small and extremely simple to use.
And, dare I say it, as used by Pappocom when he needs to determine the number of solutions for a puzzle.
