What is the bet365 acca boost?

If you’re a fan of football or tennis then odds are that you’ve heard of an accumulator, and perhaps placed one on any of our top 20 betting sites in the UK. But if not, allow me to explain. An accumulator is essentially a bet with multiple selections within it which can include multiple bets on the same game, or multiple games within the same tournament. The more selections that you place in an accumulator, the higher the potential return could be. But there’s a catch! All of your accumulator selections need to win for you to get this increased potential return. If one of the selections loses, then you’ll lose the accumulator (unless you cash out early but let’s keep it simple for now).

With the bet365 acca boost, you have the opportunity to boost your potential return by up to 100%. It’s a little different to the standard bet365 super boost since the exact amount you’re able to boost your accumulator returns by will depend on the number of selections you choose. You can make between two and 20 selections on any combinations of qualifying sports.

There are a few US major leagues that are eligible for this promotion too, just like with other uk betting promos. However, Bet365 acca boost primarily focuses on football and tennis match.

20-folds100% boost

If you make the minimum selection of two bets, then you could potentially boost your winnings by 2.5%. The more selections you make, the higher your potential bet365 acca boost, simply because the odds of you landing 10 selections for example, is much lower than two. If you make the maximum 20 selections and they all win, then you’ll boost your return by up to 100%, effectively doubling your winnings. This is one of several promotions available at this betting site that can boost your return, like the sub on play on offer.
