The rules
- Shade cells so no number repeats in any row or column.
- Shaded cells may never touch each other.
- The white cells must stay connected as one region.
- Tap a cell to shade it or ring it (sure white); drag to shade several in a row.
Getting started: When the same number appears three times in a row, the middle one must stay white — otherwise two shaded cells would touch.
