Nonogram 10×10 (Medium)
Also known as paint by numbers, picture logic puzzles, Japanese crosswords or simply nonograms. Nintendo’s Picross and Conceptis’ Griddlers are the same genre of puzzle.
The 10×10 grid is the classic Nonogram size — room for a proper picture and a satisfying chain of deductions, without a huge time commitment. Our daily puzzle uses this size, and like every board here it is verified to be uniquely solvable by logic. The game below starts on 10×10 automatically.

How to play Nonogram — the rules
- The numbers beside each row and above each column give the lengths of the filled runs in that line, in order. A clue of 3 1 means a run of three filled squares, then a gap, then one more filled square.
- Tap or click a square to cycle it: empty → filled → marked-empty (✗) → empty. Use ✗ to note squares you have proven are blank — it keeps long lines readable.
- Drag across several squares to fill or mark a whole run at once. Pick the Fill or ✗ tool for what a drag paints; long-press (or right-click) uses the other one for a single square.
- A line is done when its filled runs exactly match its clue. As you go, satisfied clues fade and cross out, so you can see your progress at a glance.
- You never have to guess. Every puzzle is verified to have one solution reachable by logic alone — if you are stuck, re-read a crossing line and a forced square will appear.
Keyboard: arrow keys to move around the grid, Space or Enter to cycle a square, X to mark it empty.
Our guarantee, honestly kept: every puzzle is checked by an independent line-logic solver before it reaches you. It confirms the picture has exactly one solution and that pure line-by-line deduction — no guessing, no backtracking — is enough to complete it. Puzzles that fail either test are rejected and regenerated.
