I was just reminded of a Sudoku game I was working on a couple of years ago as a fun project during my last semester in school. It's what I'd like to think is a pretty decent Sudoku game for the PC. (Sorry Mac users.)


There are over 4.2 billion puzzle possibilities numbered from 1 on up so you can try the same one multiple times if you'd like. You can just click the "random" button to let the computer select a random puzzle number for you.

There are five difficulty possibilities: easy, medium, hard, extreme, insane. I doubt anyone would be able to solve on insane.

Once you start a game a timer starts so you can track how long it's taking you to win (or lose). You can pause the game while playing, but if you do the puzzle will be hidden so you can't cheat.

You can enter up to 6 possible/placeholder values into a cell when you're unsure which it might be. To decide on a single one, just enter it by itself and hit the enter key. You can also use the arrow keys to move around from cell to cell.

Every five moves you can hit the "Progress" button which will tell you how many of your entries are incorrect, if any. If you're desperate for some help you can use the "Hint" button to allow the computer to randomly fill in a blank cell with the correct value, but doing so will add a 1 minute penalty to your time.

If you give up you can click "Solve It" to allow the computer to fill in the puzzle with all the correct values. Or you can use "End Game" to just quit where you are.

If you're in the middle of a game and just close the game, when you reopen it, it will pick up where you left off, so you can continue as if you never left.

There's also a statistics window that shows the history of all games you've played, including puzzle number, play time, and win/loss.

I'd love it if any of you Sudoku fanatics would give my game a shot and tell me what you think. No one except me has ever played it before, and the last time was 2 years ago.
