You start with a blank field, a few wheels, and one goal: get that little object to the target zone. So you grab building rods, snap them together, and bolt on spinning whels to create a rolling, rocking, totally ridiculous machine. Hit play and physics takes over, your contraption lurches forward, climbs hills, and hopefully drags the goal piece across the finish. It's part puzzle, part engineering sandbox, and 100% trial and error in the best way. Think you can build something that actually works?
How to Play & Controls
- Left Click / Drag to place and connect rods and wheels
- Click and drag joints to reshape or reposition parts
- Press Play / Spacebar to run your machine and test the physics
- Reset button to wipe the run and tweak your design
Tips & Tricks
- Build a wide, low base so your machine doesn't tip over on slopes.
- Use clockwise and counterclockwise wheels together to balance your drive direction.
- Place a wheel directly under the goal piece to push it instead of dragging it.
