The gameplay is that you place bets on which car will win. Like the majority of titles that are showing up these days it's a redemption / gambling title rather than something more interactive.
As I said, it's the video equivalent of many of the mechanical games (eg. Royal Ascot etc.) I've seen ones with physical cars on a racetrack too, but can't remember the titles.
