This game is based on a very popular game (in Europe). You could play it on a piece of graph paper. You can read about game's history and rules at: http://en.wikipedia.org/wiki/Racetrack_(game).
In this version of the game you will be racing a car along selected race track (four currently available). At any time you got 9 choices to advance your car to: center node and 8 nodes surrounding center node. Your choices are based on your previous move and a center node is exactly at the same distance and direction as your current location is from the previous location. At any time you can not speed up, slow down or change direction by more than one node. So, watch out for corners. Sounds complicated? It is not. You get help from the program. No need to calculate next move, all possible choices are displayed for you. All you need to do is to decide what's best for you. The time of your run on the current lap and your best time lap are displayed. The goal of the game is to beat your best time. You will be able to see a ghost of your current best time run that you want to beat. Good luck.
