Nono Zen: Nonogram Puzzle
By Micro App Digital
About this app
The logic puzzle, the way the magazines meant it. Every grid in Nono Zen is certified line-solvable — one solution, reachable by pure logic, with no guessing ever required. A solver proves it before the puzzle is allowed into the app, and any grid that would need a coin-flip is thrown away rather than shipped with a hint. There are no lives here: no hearts, no energy, no meter counting your mistakes. Solve a picture and it blooms out of the grid in full colour and joins your Gallery, titled and dated. Plus a daily grid the whole world shares, and a Zen room of endless certified abstracts.
Features
Certified Line-Solvable
- A solver proves every grid before it is allowed into the app: one solution, reachable by pure logic, with no guessing ever required.
- Any puzzle that would need a coin-flip is thrown away rather than shipped with a hint.
No Lives, Ever
- No hearts, no energy, no meter counting your mistakes.
- Erase, undo and restart as much as thinking takes — none of them carry an ad.
Graded Honestly
- Gentle, Steady, Deep and Master are named for the technique each puzzle actually needs, not for its size.
- The grade and its certificate are printed on the puzzle card before you start.
Assist Or Classic, Your Choice
- Assist flags a slip the moment you make it. Classic flags nothing until you ask, the way paper does.
- Switch between them mid-puzzle. Neither one is a difficulty setting.
Built For Real Thumbs
- Drag-paint with a direction lock, so a slip out of the line simply does nothing.
- Pinch to zoom, or switch to the precision cursor when the cells get small.
Solve It, Keep It
- Every finished picture blooms out of the grid in full colour and joins your Gallery — titled, dated, and yours.
- 26 original pixel-art pictures across six themed packs, from a 5×5 warm-up to a 20×20 evening.
The Daily Grid
- One puzzle per date, the same one for everyone, everywhere.
- Your trophy calendar stamps the days you finish and leaves the days you missed blank. There is no streak to break.
The Zen Room
- Endless certified abstracts at whatever grade suits the evening.
- No picture at the end — just the logic, for as long as you want it.
Works Offline
- Every puzzle, pack and mode works with no connection.
- Your progress, Gallery and calendar stay on your device.
