🕹️ How to play

  1. How to start: The page opens straight into a 5×5 “Little House”. The tip line walks you through the first rows; follow it or solve on your own. Next time, you'll pick up exactly where you stopped.
  2. How to fill and cross cells: Tap a cell to fill it, tap again to clear it. Press and drag to fill a whole run in one stroke; the drag stays locked to the row or column you started in. Mark known-empty cells with ✕ using the ✕ tool, a long press, or right-click on desktop.
  3. How to tell a line is finished: When a row's or column's filled runs match its numbers exactly, the numbers grey out with a strike-through and the rest of that line shows faint ✕ marks. The Lines counter tracks how many are done; match them all and the picture is solved.
  4. What to do when you're stuck: Tap Check: wrong cells get a red corner so you can fix or undo them. Still stuck? Hint highlights a line you can solve right now, one cell in it, and why, without placing anything for you. A solve with Check or Hint still counts; it just doesn't earn the no-help stamp.

📖 Rules & variants

Nonogram rules: every row (left) and column (top) has a list of numbers. Each number is a run of consecutive filled cells, listed in order, with at least one empty cell between runs; a line marked 0 is completely empty. When every row and column matches its numbers, the filled cells form a picture.

The puzzles here: 16 puzzles at 5×5, 30 at 10×10 and 30 more 10×10 that only appear as the daily puzzle, all original pixel art. A solver checks every one: each can be completed purely line by line, so the solution is unique and you never need to guess. Stars (1–3) mark difficulty, and each pack runs from easy to hard.

Tip 1, overlap: cells that a run covers whether you push it all the way left or all the way right must be filled. On a 10-cell line with clue “3 4”, the runs need 3+1+4 = 8 cells, leaving 2 spare, so cells 3, 7 and 8 are always filled. Bigger numbers and less slack give you more free cells.

Tip 2, edges and elimination: a filled cell touching the edge pins the first run, so count it out and put a ✕ after it. Once a line's numbers are all placed, every other cell in it is empty. Each time you settle a cell, look at the line crossing it. Nonograms are solved by switching between rows and columns.

Common beginner mistakes: filling by feel instead of checking whether the runs fit; treating “1 1” as one run of two; and leaving empty cells unmarked, then forgetting what you've already ruled out. Check only marks mistakes when you ask, costs no lives and doesn't stop the clock.

Modes and records: the daily puzzle is the same for everyone on the same local date and repeats every 30 days. Random practice builds a fresh picture that's still solvable by logic, and you can copy its link to share the exact board. The timer starts on your first move and stops when you switch away. Solved pictures go into the gallery, and results stay in this browser only.

This heart isn't one of the site's puzzles; it just shows the three moves you'll use most.

① Rows 2 and 3 say 5: fill them completely. No logic needed.
1 1553124442
② Columns 1 and 5 (“2”) are now complete, so cross their other cells; row 4 (“3”) fits only in the middle three.

③ Row 1 “1 1” can only go in columns 2 and 4, row 5 “1” sits in the centre, and a heart appears.

❓ FAQ

How do you play a nonogram?
You play a nonogram by filling cells so every row and column matches its numbers, which reveals a hidden picture. Each number is a run of filled cells in order, with at least one gap between runs. Nonograms are also called griddlers, hanjie or paint-by-numbers puzzles.
What does “2 1” mean in a nonogram?
“2 1” means that line has a run of 2 filled cells, then at least one empty cell, then a run of 1 filled cell, in that order. Exactly where each run starts is worked out from the crossing lines.
Do nonograms have only one solution, or do you have to guess?
Every nonogram on this page has exactly one solution and can be solved by line-by-line logic alone, with no guessing. A solver verifies each puzzle, and random practice boards are checked the same way before you see them.
What are the best nonogram solving techniques?
The most useful nonogram technique is the overlap method: fill the cells a run covers no matter where it slides. After that come edge anchoring, crossing out a line once its numbers are complete, and always checking the crossing line of any cell you settle.
Nonogram vs sudoku: what's the difference?
A nonogram has you fill cells from run-length clues to reveal a picture, while sudoku has you place digits 1–9 without repeats in any row, column or box. Both are pure logic with a unique answer, but the techniques are completely different.
What size nonogram should a beginner start with?
Beginners should start with 5×5 nonograms, which take a minute or two and teach the overlap trick. Move to 10×10 once you can finish a 5×5 without Check; they need several rounds of switching between rows and columns.
