Reveal the hidden picture by filling cells according to the number clues.

1. The numbers on each row and column describe runs of consecutive filled cells, in order. "2 1" means a run of two, then a run of one, with at least one empty cell between them.
2. In Fill mode, tap a cell to paint it. In Mark mode (or with right-click), put an X on cells you know are empty.
3. Start with the big clues: a 5-cell row with clue "5" is fully painted; with "4", the middle three are certain.
4. Cross-reference rows and columns: every cell you settle tells you something about the other direction.
5. When a line's clues are satisfied they get crossed out. Satisfy them all and the picture appears.
