You can choose between three types of bets: single, parlay and system bets.
For a single bet, you can choose the market you want and place it. Your winnings are calculated based on your stake and the odds at the time of the bet placement.
A multiple bet is a bet type that combines more than one single bets. Winnings are calculated based on the total odds of the bets in the parlay (multiplication of all individual bet odds) and your stake. A bet slip only wins if all of its selections are correct.
In a system bet, 3 or more markets are combined. You can place the bet in the "Multiple" field at the bottom of your bet slip.
The biggest difference between a multiple and a system bet is that the second one can win even if not all of the selections are correct, depending on the type of system that has been chosen. For example, if your bet slip includes 4 selections, and you choose the "Yankee" system, you can place the stake you want in the "Amount" field next to the system type. There, you can also see the odds, which will determine your potential winnings. Your bet will win if at least 2 of the 4 selections are correct and your winnings will depend on the number of the picks that were correct.
