Stranded
Keep the island whole — don't strand a tile.
A Hitori shading puzzle across five grid sizes: black out the duplicates and keep every white cell connected.
How to play Stranded
- Goal
- Black out duplicate numbers so none repeats in a row or column, keeping all white cells connected.
- Rules
- Shade cells until no number repeats among the white cells in any row or column. Two shaded cells may never touch edge to edge, and the white cells must all stay connected in one region.
- Controls
- Tap a cell to cycle it through shaded and flagged; right-click clears it back to white. Use Check to highlight any duplicate or stranded cells.
