Sticks (walls) of any color according to the image, 1 car on each player’s start space, 3 discs (gears) per player.
Increase gear (take 1 disc).
Decrease gear (return 1 disc).
Do not move but turn your car if the direction changes. Then your move depends on the current gear, direction changes and blocks in the way. (Check the back of the card for details.)
The first player to cross the goal line wins.
