Nonograms

Each row and column has a list of numbers. The numbers tell you the lengths of consecutive runs of filled cells in that line, in order. There is at least one empty cell between runs.

• Click an empty cell to fill it in.
• Right-click (or long-press on touch) to mark a cell with an X — useful for cells you've ruled out.
• Click again to clear a cell.
• Check briefly highlights any wrong filled cells in red. X-marks don't count.
• Finish when the filled cells exactly match the hidden picture.

Tip: a satisfied clue line gets crossed out. Use that as a gentle guide.
