Play Nonogram puzzles online: rules and beginner tips

How to play Nonograms

• Each clue describes the lengths of consecutive filled runs in that line.
• Read row clues left to right and column clues top to bottom.
• Leave at least one empty square between separate runs.
• Make the filled squares agree with every row and column clue.

Your first useful move

A run of 4 in a line of 6 can slide, but its middle two squares are filled in every possible position. Mark only those guaranteed squares first.

Playing on HubbardGames

Tap to cycle between filled, empty (×) and undecided, or use the Fill and Empty brushes. On a computer, right-drag to mark empty squares. Tap a green clue to mark the line’s remaining squares empty.

Choose your difficulty

Begin with 6×6 Easy puzzles, then move to 10×10 Normal or Hard. Ultra uses 15×15 and Giga 18×18; a larger screen gives those boards more room.

Can I practise without affecting the league?

Yes. Choose a puzzle from the Library to practise this game. Library practice does not add league points. You can return to an unfinished puzzle later.
