Gear Flow: Mechanical Puzzles is my Android logic game about finding the connection that makes a machine work. Place gears and follow how motion travels through the mechanism. Direction and speed matter; later puzzles add belts, shafts and clutches, leading to layered mechanisms and machines with multiple stages. Explore 400 puzzles across 34 chapters, from simple gear trains to workshop machines. Solve at your own pace or try optional timed challenges and move targets. Free to download on Google Play, with ads and optional in-app purchases. The attached images are actual game screenshots.
