How to play
Fill squares so every row and column matches its numbers. Each number is a run of filled squares, in order, with at least one empty square between runs. Finish and a picture appears.
-
3 1
3 1 in five squares fits one way: three, a gap, one.
-
4
4 in five starts at either end, so the middle three are filled either way.
- Tap a square to fill it; tap again to clear it.
- Hold or right-click to mark a square empty (a dot); again to clear.
- A number fades once its run is finished and closed off by a dot or the edge. That's your bookkeeping, not a check: only the finished picture says you're right.
- Drag to fill a line, or a block: drag across and down.
- Arrows move · Space fill · X mark · Z undo
- Bottom left: undo, start over, mark mode (taps mark instead of fill). Tap the level number to pick a level.
