Description
I haven't used the pre vala-port Sudoku much, but it didn't exactly have an ideal Hints feature.
Here is the discussion regarding Hints we had some time ago -
Should be useful enough to help players once they're already on an impossible track. "If we build it, we have to build it for people that are stuck"
"If I am stuck and I get a mismatch and so on and I press hint, it should maybe show me two numbers I filled in incorrectly. That would be useful. That's what the hint system should do instead of pointing me to the direction of the next wrong number."
Hints should preferably point out wrong things and if you've done everything right, it should point to cells you might be able to fill.
I'd like to add -
We can tie the 'Show warnings' action with Hints. If there are a large no. of cells with warnings at a point, we should enable the warnings by ourselves so that the user does not go on filling wrong values.
Also tie 'Show solution' option with Hints. Details - https://bugzilla.gnome.org/show_bug.cgi?id=734893#c3
