Do you think working on an assembly line is boring? Not if you're manufacturing Factory Balls! Your job in this clever logic puzzle game is to custom-craft each ball. You’ve got all the tools you need to fulfill every order... except the instruction manual. Yes, the classic Factory Balls puzzle game is back with fresh ideas! And this time, the balls might even have arms and legs, welcome to Factory Balls Go! In each level, you’ll see the target design of your ball on the shipping box. Starting from a plain white ball, get to work by dipping it into paint cans, using tools, and figuring out the correct order of actions to manufacture the right ball. For example: the target ball might be red on top and blue on the bottom. Maybe you should paint the ball red first, then put on a helmet to protect the top half before dipping it into blue paint... If you enjoy clever puzzles and a satisfying mental workout, Factory Balls Go! will keep your brain busy with 100 original levels. Stuck on a level? Tap the light bulb button in the top right corner for a hint. An optional in-app purchase removes ads that appear before hints. Factory Balls Go! is a game by puzzle maestro Bart Bonte.

About

Sparrows on Clotheslines

Features
Read full description

Sparrows on Clotheslines is a cozy, one-finger physics hopper. You're a little brown sparrow making its way across a sun-warmed storybook city — hopping along sagging clotheslines, gliding between terracotta rooftops, and snacking to keep your wings going. It's all one finger: • On a line or a roof — stand still to rest, hold to walk, tap to jump. • In the air — hold to fly up and forward, release to glide. Flying is fast but drains your energy. • Walk off the edge of a clothesline and you flow straight into flight — no extra buttons. Energy is the whole game. Flying across a gap is quick but costly; walking the line is slow but free. The only way to refuel is to EAT — snap up crumbs and seeds strung along the lines to top up your energy bar. Run out of energy in mid-air and you'll tumble, so plan your hops and keep your beak fed. Drift across a multi-level network of clotheslines strung between buildings, each line swaying and bending under your weight. Keep an eye out for trouble: cats lounging on the rooftops, magpies cutting across the gaps, and flowerpots tipped from glowing windows. • Cozy storybook art — soft blue skies, drifting clouds, pastel laundry and warm rooftops • Simple, gentle one-finger controls anyone can pick up • Endless, relaxing runs — perfect for 2 to 10 minutes • Instant restart, never punishing • A journey through changing cities and seasons No accounts, no nonsense — just a calm little flight from rooftop to rooftop. How far can your sparrow glide?
