Screw Drivers

Kings love fast cars, crazy creations, and crashes. Let’s find out why!
Build cars with combustion or electric engines, or maybe both? You design the powertrain using axles, gears and suspensions to get the power from the engines through the wheels and onto the asphalt. Whether you build rear-wheel-drive, or power all 30 wheels of your speed machine, as long as you engineer a gear transmission, you are guaranteed to go!
Design and engineer your own car, truck, tank, plane or whatever you can think of in the easy-to-use build editor. Whether you have 4 wheels, 16 wheels, propellers, pistons, or 50 engines... vehicle construction is all yours!
Realistic or ridiculous – it’s up to you!
There’s a group of fancy royals convinced they have the best cars in the world, and who better than you to prove them wrong! Each monarch uses different building blocks to activate special mechanical features in their vehicles. Challenge them and beat their creations to unlock new engines, wheels and gears.
Take your top turbo-powered creations, start up a multiplayer server, and invite your friends to race around the island together in a variety of tracks and challenges!
