How to play
- Some cells hold numbers. A number says how many white cells you can see from it, counting itself, looking up, down, left and right until a black cell or the edge.
- Tap a cell to make it black and tap again to clear it. Numbered cells are always white.
- No two black cells may touch along an edge, and all the white cells must form one connected group.
- Any picture that follows the rules wins. Undo and Restart are always available.
Controls: mouse or touch. Made by CalcoTools.
Tips and strategy
- A 1 is boxed in: all four neighbours are black or off the grid.
- A high number needs long open lines, so keep black cells away from it.
- Two black cells never touch, so a black cell has white neighbours on every side.
- Check that a black cell does not cut off a white corner.
FAQ
- Does the number count its own cell?
- Yes. A 1 sees only itself.
- Does the puzzle have one right answer?
- Any picture that follows the rules is accepted.
- Is the daily the same for everyone?
- Yes, on the same UTC day.
