Color by logic. Reveal the picture. Optimized for iPad and iPhone Duo. PixelFlow is a nonogram — the picture cross puzzle also known as a griddler or hanjie. 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 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 — each 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. - We don't monetize your data — your play stays yours. - Calm by design — no lives, no energy meters, no countdowns. - From a studio of puzzle aficionados who believe games should be worth your time.
