Excellent! It stops me pulling my hair out when I can't find the wrong step that messed it up.
Excellent I only use this when I'm totally stuck and it never fails. Re-another comment, logic tutorials are lengthy but can be found by doing a Google search.
Final completion only. Does not show logic. My mistake, but I hoped for logical step-by-step explanations for the solution to each box.
Not sure why this rates as a game. I think it falls into a category like "reference material" or "logic tools", not games. It also does not show any logic steps, or allow hints to show a logic path. But it does reduce the levels of frustration when a mistake is made.
Sudoku Solver Works perfectly. Source of much frustration relief!
