From the rulebook
Every row and column starts with repeated numbers. Shade cells until each unshaded number appears only once in its row and column.
Shaded cells cannot share an edge, and every unshaded cell must remain connected. Tap a cell to cycle blank, shaded, kept, then press Check when the board is solved.
