Nonogram Pure

Nonogram Pure is the nonogram app with nothing in the way. No ads, no energy systems, no subscriptions, no accounts, no tracking. Pay once, play forever. EVERY PUZZLE IS PROVABLY FAIR Each board is checked by a logic engine before you ever see it: every puzzle has exactly one solution and can be completed by pure deduction alone. You will never be forced to guess. That is the guarantee serious solvers actually care about. ENDLESS PUZZLES - 5x5, 10x10, 15x15 and 20x20 boards - Three difficulties: Gentle, Classic and Expert - Freshly generated every time, so the puzzles never run out - Solve one, tap Next, keep going THE GALLERY: 36 PICTURES TO REVEAL Every gallery board hides a hand-drawn pixel picture. Solve it and the picture blooms into full colour, then take a moment while a gentle wave sweeps across your finished work. Collect all 36, from quick 5x5 starters to grand 15x15 scenes. A NEW DAILY PUZZLE One shared daily board for everyone, every day, fully offline. Keep your streak alive, browse the calendar to play any day you missed, and share your time with no spoilers. A home screen widget keeps today's board one tap away. BADGES Fourteen quiet achievements that live on your device, from your first solve to a flawless board and revealing the whole gallery. No accounts, no leaderboards, just your own record. BUILT FOR SOLVING - Drag to fill runs, with the line locked to your direction - Mark X's that can never wipe out your filled cells - One-tap undo for the whole stroke - Auto-X completed lines (optional) - Purist mode: no feedback until the puzzle is complete, or assisted mode with mistake highlighting. Your choice - Pinch to zoom on the big boards, plus a one-tap zoom button, with row and column highlighting - Four board colours: Sky, Forest, Rose and Slate - On iPad: hardware keyboard solving (arrows, space, X) and trackpad pointer highlighting - Dark mode, haptics, soft optional sounds, and your progress saved the moment you leave - Reduce Motion support for a calm, fade-only reveal PRIVATE BY DESIGN Nonogram Pure collects no data whatsoever. There is no network code in the app. Your puzzles, times and streak live on your device, full stop. One small price. No catches. That's the whole idea.
