Shade cells so that no number repeats in a row or column. Keep all unshaded cells connected.
Choose a tool, then tap a cell. Repeat to erase a mark.
Use arrow keys to move and Enter to act. Scroll the enlarged board to reach every cell.
How to play
Shade numbers so that none repeats among the remaining white cells in any row or column. Shaded cells cannot share an edge. All white cells must form one orthogonally connected group. Use Keep white to confirm unshaded cells; a dot marks that decision.

A cell between two matching numbers must be white: at least one matching number is shaded, so the middle cell cannot be shaded. A cell must also stay white if shading it would disconnect confirmed white cells.
