Hints

—

Fill every row, column, and irregular region with the digits 1–9, each used exactly once.

Unlike classic Sudoku, the nine boxes are jigsaw-shaped regions outlined in cyan.
Tap a cell, then tap a number — or use your keyboard (1–9, Backspace).
Toggle Notes to pencil in candidates.
Conflicts highlight in red across the row, column, and region.
