How to Play
A nonogram (also called picross or a paint-by-number puzzle) hides a pixel picture behind a grid of numbers. The numbers beside each row and above each column list the lengths of the filled blocks in that line, in order, separated by at least one blank square. Use them to work out which squares must be filled. Tapping a square cycles it from blank to filled to a cross marker and back, so you can mark squares you have ruled out. Play today's picture for a board that is identical for everyone until midnight, or a random picture for endless fresh puzzles. The size selector switches between 5x5, 10x10 and 15x15 grids.
Controls
- Tap a square to fill it
- Tap again to mark it with a cross
- Tap a third time to clear it
Tips & Tricks
- 1Start with the rows or columns whose clues fill the whole line
- 2Mark squares you have eliminated with a cross
- 3Overlap the largest clue with the line length to find forced squares
Frequently Asked Questions
What do the numbers mean?
Each number is the length of a run of filled squares, and runs are separated by at least one blank square.
Is there a penalty for mistakes?
The puzzle counts misplaced marks so you can see how clean your solve was, but it does not stop you.
What is today's picture?
A puzzle generated from the current date, so everyone playing that day reveals the same pixel picture.
