In an accumulator, also called acca, you combine a number of different bets of whole games or single events and consolidate them into one slip. The biggest advantage of multiple bets is that the different odds of the various legs are multiplied, and thus the combined odds are drastically high and you can yield a good profit. That is why this predictions form is so popular with beginners.

Let’s take a look at this scenario: As your first you take the game RB Leipzig vs FC Koln from German Bundesliga. You prediction on RB Leipzig as a (kind of) sure prediction at odds of 1.29. Your second prediction is Schalke vs Mainz at odds of 2.15 on a home team win.

From above, when you multiply those two odds you get your overall odds of 2.78. This is way it's higher odds than if you just predicting on one leg. If you want to further enhance your overall odds, you can add another leg to your acca. This is called a treble.
