About Nonogrids (BrainBashers)

Nonogrids follows the rules of the puzzle known as nonograms, griddlers or paint by numbers. Beside each row and above each column is a short list of numbers. Each number is the length of a run of consecutive filled squares in that line, and the runs appear in the order listed, with at least one empty square between them. A clue of 3 1 2 means a run of three, then one, then two. Working back and forth between rows and columns, you fill in the blocks until every line matches.

Kevin Stone's BrainBashers posts five grids a day that grow with the difficulty: 5x5 and 10x10 at Easy, 15x15 at Medium, and 20x20 and 25x25 at Hard, with a 30x30 weekly special. The play page has check, answer, print and restart buttons, an option to show mistakes, an optional clock and an alternative border style that helps on big grids. A help page walks through the method.

The set changes at midnight GMT or at the time zone you set, and the date list keeps a few weeks of earlier days. No adverts, no account.

It suits nonogram fans who want a daily set that runs from a one-minute warm-up to a long 25x25.

How to play Nonogrids (BrainBashers)

1. Open the Daily Nonogrids page and pick one of today's sizes.
2. Read the clues: each number is a run of filled squares, in order, with gaps between runs.
3. Fill the squares you can be sure of, and mark squares you know are empty.
4. Switch between rows and columns, using each new square to unlock the crossing line.
5. Check your grid or reveal the answer; new grids appear after midnight GMT.

Tips

• In a line of 15, a clue of 10 fills the middle 5 squares wherever the run starts.
• Add up a line's clues plus the gaps between them; if that equals the line length, the whole line is fixed.
• A 0 or empty clue means the whole line is blank.
• Work from the edges: a filled square at the border starts the first run in that line.
