Color by logic. Reveal the picture. PixelFlow is a free-to-start, ad-free nonogram — the picture cross puzzle also known as a griddler or picross. The numbers along each row and column tell you which squares to fill. Work out the cells you can be sure of, fill them in, and a small picture quietly appears under your fingers. No ads. No data monetization. No pop-ups begging for your attention — ever. Just clean, quiet, thought-provoking and calming puzzles that respect your time. WHAT'S INSIDE - 150 logic-checked puzzles — each has a single logical solution, so you never have to guess. - 16 themed Picture Packs, from Garden, Voyage, and Tide all the way to Aurora, Meridian, and Frontier — every pack with its own mood and palette. - Hold HINT for a gentle nudge — it reveals just one row and column, never the whole answer. - No timer pressure, no countdown, no way to lose. Prefer a clean board? Turn the stopwatch off. - Plays entirely offline. A FREE PUZZLE EVERY DAY A new Daily Puzzle every day, free — a quiet ritual, and a streak if you want one. BEAUTIFUL ON iPAD On iPad, PixelFlow uses the space instead of stretching into it: the board, menus, and layouts are tuned for the larger screen, in portrait and landscape. HOW TO PLAY A clue like "3" means three filled squares in a row. "1 1" means one square, a gap, then one more. Cross-check the rows against the columns to find the squares that can only be one thing — and the picture builds itself. WHAT WE BELIEVE - No ads, ever. - Privacy-first. No data monetization. - Exercising your mind through puzzles is fun. - From a studio of puzzle aficionados who believe games should be worth your time. THE PUZZLE MASTER COLLECTION PixelFlow is part of the Puzzle Master Collection, alongside ColorFlow, ColorFlow: Worlds, Juliet's Dilemma, and more from our growing family of calm, ad-free games. The Collection is free on the App Store — one download, every game, free to try. The Starter and Grove packs and the Daily Puzzle are free for good; when you want the rest, unlock every Picture Pack once and keep them forever — or choose the optional Puzzle Master Pass and play the whole collection. Fully localized in 12 languages — menus, puzzle packs, and even the picture names.
