About the game
Two modes! WRECK: jump the rocks — every hit tears parts off, and the car keeps going as long as it has a wheel (down to the last one, you ride ON it). CAREER: the car is your capital and every hit cuts its resale price; earn in races, sell up and work your way from a beater to a supercar.
How to play
Open the game and start right away — no install, no account. On a computer use the mouse or arrow keys, on a phone just tap. Your result is stored on your own device.
