Then divide the total prize money this horse has won in its entire career by the figure you just got to get a Master Prize figure. When you have done this for each runner, your selection is the horse with the highest Master Prize figure. This is a simple formula, but paper trade it for a while and, like us, you will conclude that it really does help to pick winners on a regular basis. If you want to win regularly, bet only on horses that won their last races. If there are several horses in the same race that won their last races, you can either bet on all of them or you can ignore the race altogether.
Some people limit themselves to betting on a maximum of three previous winners in the same race.
If there are more than three previous winners, they skip that race. By betting on horses that have already proved they can win, you're not expecting them to do anything more than they have already achieved. Rather, you bet according to the parimutuel system. Under the parimutuel system, you are betting against the other bettors on the race. That means if a lot of people bet on the same horse and it wins, each person gets a small payoff.
