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.

Verdict
The clearest difference is in-app purchases: Shikaku at none against PixelFlow's 4. Shikaku also leads on iOS requirement (15.1 vs 17.0). PixelFlow's advantage is ads (none vs shown). On price and device support there is nothing between them.
