About game

Sometimes a brilliant machine is missing just one part. Choose a ramp, spring, bumper, fan, magnet, gravity field, or conveyor. Place it on the blueprint, find the right angle, and start the mechanism. Guide Spark past the obstacles, collect the gears, and reach the portal. The game includes: • 24 handcrafted puzzles across four chapters; • a shared six-link Daily Machine; • an endless challenge built for high scores; • link-based relays you can continue with friends; • free hints with no mandatory ads; • one-finger, mouse, and keyboard controls; • English, Russian, and Turkish interfaces; • local progress with no sign-in required. Every blueprint follows one simple rule: you may add only one part. There can still be more than one ingenious solution. Experiment, collect every gear, and turn physics into mechanical poetry!

How to play

1. Choose one part at the bottom of the screen. 2. Drag it into the dotted area of the blueprint. 3. Rotate it with the on-screen buttons or Q/E. 4. Select “Launch,” or press Space/Enter. 5. Guide Spark into the portal and collect as many gears as you can. Keyboard: arrow keys move the part, Q/E rotate it, Space or Enter launches, R resets, and Esc pauses. On mobile, every action is available by touch.
