### Go Play Sudoku Website

Hi Guys, I'm Jerick. I developed an online sudoku game. There are 3 levels Easy, Normal and Impossible. Until now no one can solve the Impossible level. I'm challenging you guys to solve the impossible level.

### Great website to play sudoku

GoPlaySudoku.com is a good website to play with. It has 3 levels. Easy, Normal and Impossible. Easy level is a good level to practice because it will highlight the wrong answers by red after you submitted it. Normal and Impossible levels don't tell you the wrong items. I just checked it and until now no one can solve the Impossible level.

I have to agree with Jason: according to my sudoku program that puzzle has 195153 solutions!!
I checked another in case it was a one-off:
Code: Select all
`6.1.....44..8...5....6......19.34......5............481......7......34...7.4....5`

and this one has 51276 solutions.
The property of uniqueness must be satisfied. I think you need to go back to the drawing board.

The easy puzzle below has only one solution, which is good, but 29 of its 36 clues are individually redundant: the puzzle is not minimal. A version that is still easy but minimal is

Code: Select all
`.....75..5..1...94.62.3......43...572.8..6......5..1...3.86...1.8................`

That's why it's called "impossible".

Hi Bill,
Nice to see you still here.
Are you still doing Kakuros or Slitherlinks? Have you found any interesting new ones?
