Objective: Race your car to the goal area in as few moves as possible.
(12 variants, two of them randomized, nine of them create-your-own-track)

This classical pencil-and-paper game simulates a car race.
Click the 'Start' button first to let the system display the racetrack.

To drive, click one of the yellow target positions.
With each move the speed of your car can only be changed incrementally, as indicated by the white target squares.

The green areas are no-go areas. If you don't manage to stay on the track, you lose.
However, if you drive fast enough, you can 'jump' over small green patches.
You win if your last move ends in the grey goal area.

The red patches on the track show potential oil slicks. By default the oil slicks are deactivated.
You can activate the oil slicks by clicking the 'Oil' button at the right border.
You can select this button only just before you move your car the first time.
If you drive your car onto an active oil slick you will lose your steering.
You can make the (active or inactive) oil slicks invisible via the View/SwitchPieceSet menu option.

At the right border, the top number shows the best race count, underneath it the current round is shown, and below this we see the current speed in the x and y directions (hor. and vert.).

• Variant 1: Martin Gardner's version.
  Try to use 36 moves or less (with oil slicks off). The best known solution is attached.
• Variants 2,3: Randomized racetracks.
  These racetracks are loosely based on the track of variant 1.
• Variants 4,5,6: create your own track.
  First you drop 20, 30 or 40 green blocks of size 7x5 anywhere.
  Indicators on the right border show how many blocks are left to be dropped.
  Then you drop your car and the goal area (size 6x4).
• Variants 7,8,9: create your own track.
  Click the 'Start' button first. The system will display a green canvas.
  Now drop 20, 30 or 40 rectangular racetrack pieces of size 7x5 anywhere.
  Finally you drop your car and the goal area (size 6x4).
• Variants 10,11,12: create your own track.
  Click the 'Start' button first. The system will display a green canvas.
  Now drop 20, 30 or 40 round racetrack pieces of size 7x5 anywhere.
  Finally you drop your car and the goal area (size 6x4).

To drive a blue car, choose an alternate piece set.

The ability to create your own racetracks makes this game stand out from similar Windows games by other authors.

You can also edit the given tracks with mouse clicks before you move the car:
DEL+Mouseclick eliminates green area and hence increases the track area;
CTRL-C and CTRL-V together with Mouseclick copies green area and hence can reduce the track area.
