Griddigit — Classic Sudoku

Griddigit is Sudoku, the way it should be: no ads interrupting your focus,
no ambiguous puzzles, just clean logic from the first cell to the last.

Fill the 9×9 grid so every row, column, and 3×3 box contains 1 through 9
exactly once. Tap a cell to select it — its row, column, and box highlight
automatically — then tap a number to place it.

Every puzzle has been checked by a real solver to guarantee a single,
logical solution. No guessing, ever.
