About this puzzle
Key 30x30 Nonogram sits in the symbol theme as a medium 30x30 board. 349 of its 900 squares are filled, so it reads as a fairly balanced grid at roughly 39% coverage.
The biggest single run here is 18 cells long — fill that first and the surrounding lines fall into place faster. Expect to spend roughly 10 minutes from a blank grid to the finished picture.
How to solve this nonogram
On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Turn Challenge mode on for instant feedback on mistakes, or leave it off for a calmer solve.

PlayFAQ
FAQ
Which grid sizes can I play the key nonogram in?
30x30, 40x40. Smaller grids show a simpler outline and take a few minutes; larger ones add detail and turn into a longer, more careful solve.
Does this puzzle save my progress?
Yes. Your moves and timer are saved in the browser after every action, so you can close the tab and come back later without losing anything. Each grid size keeps its own progress.
How do I check for mistakes?
Tap Check any time for a manual review, or turn on Challenge mode for immediate feedback as you play.
What do the X marks do?
X marks flag cells you've proved are empty. They don't affect the solution, but they make bigger grids much easier to track.
