How to play Nonogram

Use the number clues to fill in squares and reveal a hidden picture.

The rules, step by step

The numbers beside each row and above each column give the lengths of the runs of filled squares, in order.
A clue of "3 1" means three filled squares in a row, then at least one empty square, then one more filled square.
Tap a square once to fill it. Tap again to cross it out, which means you know it is empty. Tap a third time to clear it.
The puzzle is finished when every row and column matches its clue.
You never need to guess: every puzzle can be solved by logic. Press Check to see wrong squares, or Hint for one square.

In a line of 5, a clue of 5 fills every square. A clue of 4 must fill the middle three squares whichever way it sits.

Once a row has all its filled squares, cross out the rest of that row.

Begin with the longest clues: they overlap the most.
Work back and forth between rows and columns. Each filled square helps the other direction.
Cross out squares you know are empty. It keeps your thinking tidy.
