A Quaddie bet, or Quadrella bet as it is fully known, is available on most thoroughbred, harness and greyhound race meetings.
A quaddie is betting on the winners of four nominated races, which are usually the final four races of any meeting, and is a very popular bet. All quaddie bets go into a pool and a dividend is paid out for those successfully predicting the four winners of the races in question.
Punters can pick one horse per race or opt for several horses per race and hope the one of the selected runners win in each of the races, which will diminish the potential return.
To win a quaddie, you must have selected all four winners. A dividend is then paid out and declared as a $1 unit, and can range from $50 up to hundreds of thousands of dollars.
With a quaddie, you can set the budget you are willing to spend and ensure your spending does not get out of control.
WHERE TO PLACE A QUADDIE
You can select any number of runners in each race to maximise your chances of picking the winner. For every runner you do select, however, you are reducing the percentage of the dividend you will collect.
HOW TO CALCULATE A QUADDIE
To calculate the quaddie you have to multiply how many runners you have nominated for each leg. For example if you select four runners in the first leg, three in the second, one in the third and two in the fourth your outlay will be $24 to get a 100% return on your bet.
If one or more of your selections are declared non-runners or are scratched after you have placed your bet, your scratched runner will be replaced by the substitute runner which is declared by the based on the runner with the greatest number of win units invested upon it.
