Nonogram
Read the row and column clues to uncover a hidden pixel picture.
How to play
- Read each row and column clue. A clue such as “3 1” means a group of three filled squares followed later by one filled square, with at least one empty square between them.
- Choose Fill to paint squares that belong to the picture. Choose X to mark squares you know must stay empty; on a computer you can also right-click to place an X.
- Use clues from both directions together. Completed row and column clues fade automatically, helping you concentrate on the lines still in progress.
- Fill every square in the hidden picture to finish. Empty squares do not all need crosses, and there is no penalty for checking, undoing or taking your time.
What it trains
- Structured deduction practice — every decision must satisfy both a row and a column
- Visible progress that gradually turns abstract number clues into a recognizable picture
- Four board sizes, gentle tools and no failure state make it easy to learn at your own pace
