25×25 Nonogram puzzle
Every puzzle verified — one solution, pure logic, no guessing
Clue numbers count consecutive filled squares. Tap or drag to fill, right-click or long-press to cross. Full rules
The size a scene needs
At twenty-five squares a side a nonogram holds a real subject: a galleon with rigging, a peacock with its fan, a dinosaur from nose to tail. These are the pictures the smaller sizes cannot carry.
Built for long work
The pinned clue gutters, the corner map, per-size zoom memory, and automatic saving exist for exactly this grid. Crosses stay where you put them, the undo history runs fifty moves deep, and nothing asks you to start over.
Verified like every other size
Big does not mean ambiguous. Each 25×25 is checked to have one solution and one only — the same promise the five-minute grids keep.
Common questions
- How long does a 25×25 nonogram take?
- Plan for one to three hours. It is a sitting, not a break — which is exactly what the size is for. Progress saves automatically, so it can also be three evenings.
- How do I keep my place on such a big grid?
- The clue gutters stay pinned while the board pans, and the corner map shows the whole picture with a frame around the region on screen. Tap the map to jump. Your zoom level is remembered per size.
- Is a 25×25 harder than a 15×15?
- It is longer more than it is harder. The techniques are the same — and every grid is verified unique, so patience always beats guessing. The Logic readout says how deep the reasoning runs.
