Object: Eliminate all Bumper Cars (except one).

You may only click a Car that can bump into another Car (see below)!

The Car will rotate 90, 180 or 270 degrees then drive as far as empty space is available.
If after a rotation of 90 degrees there is no empty space in front of the Car, then the Car will rotate 180 degrees.
If after a rotation of 180 degrees there is no empty space in front of the Car, then the Car will rotate 270 degrees.
If after a rotation of 270 degrees there is no empty space in front of the Car, then the Car cannot move.

If after its rotation and driving the clicked Car 'bumps' into another Car, then this second Car will be disappear.
The tricky bit is that in this game you can only click a Car that will bump into another Car.
If you are not sure which car can move, hit key F7.

You win when only one Car is left on the road.
The colour of the cars have no effect on the rules.

Randomized variants: Click the board to create a random setup of 8, 12 or 16 Cars.
Eliminate as many Cars as possible.
