Single bet is when you pick the outcome of one event. You can win the odds multiplied by your stake. You can make a series of single bets using the ‘Single’ tab at the top of the betting slip.
Parlay bet is a bet that depends on the outcome of more than one event – you can add up to 12 events. This is an parlay and you need to have predicted every event correctly to get a return. If you win, your stake will be multiplied by the total odds of the selected events.
