So here is one sudoku I found in some sheet of paper from a puzzle magazine just lying peacefully on my desk.
Click
Well, it um... kinda proved unsolvable.
Then I ran it on the solver above and This has been able to solve every single puzzle I put into it so far(even the unsolvables from sudoku.org) and this it couldn't solve! I'm kinda shocked.
P.S. I double/tripple checked if all the numbers are in the right place(and they are) and now tell me how to solve it without guessing(cuz I find that impossible at the moment). |

Hello martix,
I fed this to a uniqueness-checker and it told me that there are multiple solutions.

My Sudoku Solver also reports that multiple solutions exist for that Sodoku. I Coded my sudoku in Java using a backtracking algorithm with sophisticated guessing. My solver is online and you'll need the Java plugin enabled if you want to use it, click here. |
