In this game you are a real Jockey. Train your own horse so that he becomes strong and fast enough to win the race together with you. For every race you win, you get a goblet and a moneyprize, with this money you can buy better food and vitamines for your horse which can result in you winning the next races as well. After every race you won, you get to do a harder race. Fly around the world and collect all the goblets.
