Hmm, I have tried this but didn't get far. So I tried to check it with various solvers, and they all claim that there is no solution. So is it correct? Is your solver doing something no one else do? Just wondering... exactly one solution. You tried the wrong solvers Yes, there is only one solution. My solver can do it in the fastest time it can solve any sudoku (16 ms) so I would not consider it as very hard / tricky!
