About game

Sometimes, a perfect machine lacks just one detail. Select a ramp, spring, bumper, fan, magnet, gravity field, or conveyor. Position it on the blueprint, adjust the angle, and set the mechanism in motion. Help Spark overcome obstacles, gather gears, and reach the portal. What the game offers: • 24 meticulously designed puzzles across four chapters; • a collaborative six-link Daily Machine; • an endless mode for chasing high scores; • relay challenges that you can continue with friends; • free hints without mandatory ads; • intuitive controls for one finger, mouse, or keyboard; • support for English, Russian, and Turkish languages; • local progress tracking without the need to sign in. Each blueprint adheres to a simple rule: add only one part. Yet, there can be multiple brilliant solutions. Experiment, collect all the gears, and turn physics into a symphony of mechanics!

How to play

1. Pick a piece from the lower part of the screen. 2. Move it to the dashed section of the plan. 3. Use on-screen controls or Q/E to rotate the piece. 4. Click "Launch" or hit Space/Enter. 5. Lead Spark to the portal, collecting gears along the way. Controls: arrow keys to move the part, Q/E for rotation, Space or Enter to launch, R to reset, and Esc to pause. On mobile devices, all actions are performed with touches.
