About Paint by Numbers
Paint by Numbers (also called Picross or Nonogram) is a logic puzzle where you fill cells in a grid to reveal a hidden picture. Each row and column has a list of numbers called "clues" — these tell you how many consecutive filled cells appear in that line. Use logic to determine which cells to fill!
Controls
- Left click / tap — Fill or unfill a cell (in Fill mode)
- Right click / Mark mode — Place an X to mark a cell as empty
- Fill / Mark buttons — Switch between fill mode and mark mode
- Check button — Highlight any errors in your filled cells
How to Play
- Numbers on the left = clues for that row (groups of filled cells, left to right).
- Numbers on the top = clues for that column (groups of filled cells, top to bottom).
- A clue of "3 1" means: a group of 3 filled cells, then at least one gap, then 1 filled cell.
- Fill cells to match all clues simultaneously — no guessing needed!
- Use X marks to track cells you know are empty.
Frequently Asked Questions
Multiple numbers mean multiple separate groups. "2 3" means a group of 2 filled cells, then at least one empty cell, then a group of 3 filled cells — in that order.
No! Every puzzle has a unique solution that can be found purely through logic. Start with rows or columns where the clues are large relative to the grid size — those constrain the solution the most.
The X mark (right-click or Mark mode) helps you track cells you've logically deduced are empty. It's optional but very helpful for keeping track of your reasoning. Marked cells don't count as errors.
