It can solve sudoku. It took 119s to solve this easy grid:

_ 7 8 4 1 _ _ _ 9

5 _ 1 _ 2 _ 4 7 _

_ 2 9 _ 6 _ _ _ _

_ 3 _ _ _ 7 6 9 4

_ 4 5 3 _ _ 8 1 _

_ _ _ _ _ _ 3 _ _

9 _ 4 6 7 2 1 3 _

6 _ _ _ _ _ 7 _ 8

_ _ _ 8 3 1 _ _ _



I tried to have it solve an easy Sudoku grid too, but in my case it failed miserably. It kept making mistakes and saying that there was a problem with the puzzle (there wasn’t).


It seems to be unable to solve hard sudokus, like the following one where it gave 2 wrong answers before abandoning.

+-------+-------+-------+ | 6 . . | 9 1 . | . . . | | 2 . 5 | . . . | 1 . 7 | | . 3 . | . 2 7 | 5 . . | +-------+-------+-------+ | 3 . 4 | . . 1 | . 2 . | | . 6 . | 3 . . | . . . | | . . 9 | . 5 . | . 7 . | +-------+-------+-------+ | . . . | 7 . . | 2 1 . | | . . . | . 9 . | 7 . 4 | | 4 . . | . . . | 6 8 5 | +-------+-------+-------+

So we're safe for another few months.
