Fill mode: tap or drag to paint the picture. Switch to Mark to X out blanks.
How to play
- Numbers along each row and column tell you the runs of filled cells in order.
- Tap a cell to fill it, or switch to Mark mode to X-out cells you know are empty.
- A clue like "3 1" means a run of three filled cells, a gap, then one filled cell.
- Fill exactly the right cells to reveal the picture and win.
Strategy & tips
- Start with the biggest clues — in a 10-wide row, a clue of 8 leaves little room and forces cells.
- Mark cells you know are empty with an X; ruling out is as useful as filling in.
- Cross-reference rows and columns: a cell filled by a row clue can unlock a column, and vice versa.
- Look for overlaps — where a large run must cover the same cells no matter where it sits.
- Work from the clues you are certain about outward; never guess when a deduction exists.
