How to solve this nonogram

Read the numbers beside each row and above each column to work out which cells must be filled. A clue like "3" means three filled cells in a row; "2 1" means two filled cells, at least one empty cell, then one filled cell. Start with the longest clues, mark cells you've ruled out with X, and re-check neighbouring lines until the picture comes together. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.
