- Use the Check Grid button to review your progress.
- Do not guess too quickly; look for rows or columns with only one possible pattern.
Frequently Asked Questions
What is a Griddlers or Nonogram puzzle?
It is a picture-logic puzzle where number clues indicate groups of consecutive filled squares in each row and column.
How do I read the number clues?
Each number represents a consecutive group of filled cells. If a row has clues 3 and 2, it contains a group of three filled cells and a group of two, with at least one empty cell between them.
What does Mark X do?
It marks a square you believe should remain empty. X marks are notes and do not count as mistakes.
What happens if I make three mistakes?
The challenge ends when you fill three cells that do not belong to the hidden picture. You can restart the same puzzle and try again.
What does the Hint button do?
It reveals one currently unfilled square that belongs to the solution. Hints are limited per puzzle.
Can I play different grid sizes?
Yes. Choose 5 x 5, 10 x 10 or 15 x 15 from the Grid menu.
Does the game save my progress?
Your best completion time is stored locally for each puzzle and grid size. Clearing browser data may remove these records.
Can I play on a mobile phone?
Yes. The board is responsive and supports touch input. You can select Fill, Mark X or Erase before tapping a cell.
Is this the same as Minesweeper?
