You're staring at a tangle of mismatched gears, and your job is to make every single one spin together in perfect harmony. Gears and Chains Spin It is a brain-bending puzzle game where you drag gears onto pegs, link them with chains, and figure out how to transfer motion across the whole machine. Each level locks you with limited spots and a fixed set of pieces, so you've got to think about which gear goes where and how the chains wrap around to keep the rotation flowing. Place one cog wrong and the whole contraption jams up cold. Can you get every gear turning at once?
How to Play & Controls
- Left Mouse Click / Tap to pick up and place gears onto the open pegs
- Drag and release to connect gears with chains across the board
- R to reset the current level if your setup grinds to a halt
Tips & Tricks
- Start by placing the gears closest to the powered source so motion has somewhere to travel.
- Use chains to bridge gears that sit too far apart to mesh directly.
- Leave the trickiest gear for last and build the chain toward it.
