Play Nonogram free and ad-free — picross-style logic puzzles solved from row and column number clues. Three sizes (5×5, 10×10, 15×15), fill / mark-X cells, auto-crossing completed lines, hints, a mistake counter, timer and best times. 100% offline and private. No ads, no signup, no account.
On Mac, Windows, Linux or any computer: just click "Open Nonogram" above — it runs right in your browser, no install needed. To keep it like a desktop app, click the install icon (⊕) at the right of Chrome or Edge's address bar, or use Safari's File → "Add to Dock" on a Mac.
On iPhone or iPad: open it in Safari, tap the Share button, then "Add to Home Screen." It behaves like a native app — full-screen, offline-capable, launches from your home screen.
