Sudoku ArtSudoku Art's most demanding level
Expert level offers grids with the fewest starting digits and the longest deduction chains. It's best suited to players already comfortable with classic Sudoku.
Who this level is for
If you regularly finish hard grids without a single hint, expert is your next step: it demands patience and a careful reading of the grid before every move.
Challenges worthy of the level
Just like other levels, a finished expert grid reveals a picture and can be sent as a challenge to other players, to see who finishes it fastest, with the fewest errors and hints.
