Read full descriptionHide full description
Bringing the Casual, back to Casual Games A premium, minimalist physics puzzle game where logic is your only tool. Solve intricate mechanical boards by unscrewing various puzzle pieces using a 100% realistic physics engine. Only Screw Puzzles features no ads every tap, no pay-to-win mechanics, no deceptive levels, and no bloated mini-games. Experience pure, tactile, and fair mechanical challenges. Only Screw Puzzles was inspired by my own need for a casual game that was actually casual. When I want a five-minute break to release some puzzle pieces, I don't want to be shown windows of upgrades or forced to play mini-games for a high score. I want the game to just start. I created this game to focus on the core, mechanical gameplay. No noise, no fluff — Only Screw Puzzles. No Ads every Tap or for Bonuses — Only Screw Puzzles I am not interested in pulling you into an endless loop of watching ads just to get an upgrade or move to the next level. I respect your time. In this game, you only watch a single ad, and every tool or upgrade is yours for the entire level. You can stay in the flow without being interrupted every thirty seconds. No Pay-To-Win Microtransactions — Only Screw Puzzles You cannot buy your way through these puzzles. There are no super-boosters or paid skips designed to take your money. Whether you solve a level depends entirely on your own spatial reasoning and logic. It is a fair challenge, every single time. No Deceptive Levels — Only Screw Puzzles I don’t use psychological tricks to get you to watch ads. Many games in this genre are designed to look solvable, only to reveal an impossible bottleneck right when you are close to completion. They wait until you’ve invested time and effort before forcing a "fail" state that requires an ad to fix. In Only Screw Puzzles, every board follows the laws of physics consistently from start to finish. There are no hidden traps or scripted failures. If you can see a solution, it will work. No Mini-Games or Side-Quests — Only Screw Puzzles You don’t have to deal with unwanted bloat here. There are no side-quests to play just to get upgrades, and no chores to complete before you can progress. I focused 100% of my energy on creating high-quality, realistic physics puzzles. This isn't a game about decorating a house, managing a farm, or playing match-three sub-games—it is exactly what the name says. Full Control with Custom Levels We all have days where we want a brain-melting challenge, and other days where we just want to unwind and watch things fall. If you hit a complex level but just feel like relaxing, you have full control. My Custom Level mode lets you set the following rules to fit your mood: • No. of Layers • No. of Puzzle Piece Shapes • Puzzle Piece Materials • No. of Puzzle Piece Screws • No. of Screw Colours • No. of Screws in Boxes Realistic Materials and Weight To make the physics feel truly authentic, I’ve included the following materials that have their own physical properties for different physics. You’ll feel the difference in how they swing, collide, and drop, adding an extra layer of tactical depth to every move you make. • Foam • Wood • Metal • Stone Only Screw Puzzles is an honest, premium experience built by someone who actually loves the genre. If you are looking for a tactile, realistic physics puzzle that stays out of your way and lets you play, this is for you. ———— Apple Terms Of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
