How to play Picross (Nonograms)
Picross — also called Nonograms, Griddlers or Hanjie — is a picture logic puzzle. Each row and column has a list of numbers; each number is the length of a run of filled cells, given in order, with at least one empty cell between runs. By cross-referencing the row and column clues you can deduce exactly which cells must be filled, and a hidden picture gradually appears. There's no guessing in a well-made nonogram — every cell can be reasoned out.
Tips
- Start with the big numbers. A clue close to the row or column length overlaps itself — those overlap cells are always filled.
- Cross out the empties. Marking cells you know are blank is just as important as filling — it stops you re-checking them and reveals new deductions.
- Work the edges. A clue starting at an edge fixes the first run's position immediately.
- Switch between rows and columns. Each fill you place gives the crossing line new information.
Grid sizes
- 5×5 — quick, friendly puzzles to learn the rules.
- 10×10 — the classic size, a satisfying few minutes each.
- 15×15 — larger pictures with more deduction.
- Daily — one shared puzzle that changes every day.
