How to Get a 100% Boost On Your Next Accumulator (Across 10+ Sports)

Online sportsbooks come with plenty of unique yet generous bonuses, one of my favorites being accumulator boosts. Accumulator boosts are very simple in theory: you place a bet, and when you win, you get up to a 100% profit boost.
The accumulator boost bonus is relatively common, with bet365’s new 100% Acca Boost offer being a sterling example of the promotion in practice. In this guide, I’ll show you how accumulator boosts work in detail and how to get a 100% boost on your next accumulator bet across 10 sports on leading online sportsbooks.

What’s an accumulator boost bonus?
An accumulator boost is a popular bonus type on sportsbooks that boosts the outcome of your parlay by up to 100%. The bonus typically comes with very specific terms and conditions, often dictating what types of bets you can place, odds limitations, and how the number of games in your parlay affects the boost percentage you’ll get.
A good example of an accumulator boost bonus is bet365’s 100% Acca Boost offer. The promotion is an alternative welcome bonus for new users placing their first accumulator bet on the platform, and it works across a variety of sports: UFC, soccer, basketball, baseball, hockey, football, you name it. When you make a parlay bet consisting of between 2 and 20 selections, you get an additional 2.5% to 100% on the bet’s outcome if you win.
bet365’s Acca Boost bonus comes with plenty of restrictions and terms. For one, it doesn’t cover all sports and betting markets—only the Result/Both Teams To Score markets are covered in soccer, for example. Also, the bonus will be void on bets placed using Bet Builders or Bet Builder+ and any parlay that includes odds less than 1.10. The accumulator boost on doubles is only 2.5%, trebles are 5%, and 4-folds is 7.5%, with gradual increases up to 20-folds that pay the full 100% boost.
Not all accumulator boost bonuses work exactly like bet365’s, but most high max payout betting sites offer similar terms on the bonus. Before opting for one, consider going through the bonus terms to have a good idea of how the bonus works.

How to get an accumulator boost
Here are the steps you’ll typically have to follow to claim an accumulator boost on an online sportsbook:
Most accumulator bonuses are welcome offers, so you only get them if you’re signing up as a new user, making an initial deposit, and placing your first accumulator bet. At this stage, you only need to find a site that offers acca boosts, like bet365, sign up for an account, and make your first deposit to enable you create a parlay.
Next is making an accumulator bet, a relatively straightforward process on most sportsbooks. Most sportsbooks already order their games beautifully with the associated odds; you simply tap or click on the odds corresponding to the bet you intend to make to add the selection to your parlay. Do this several times to create a bet slip, choose a bet amount, and confirm your selections.
Note that some sportsbooks, like bet365, will offer limited boosts depending on how many games are in your parlay. On Bet365, for example, doubles only come with a 2.5% boost, while 20-folds come with 100%, so you want to check the bonus terms before locking in your selections.
Accumulator boosts often come with all sorts of terms and conditions to keep the game fair for everyone. Defaulting on any terms could lead to forfeiting your bonus, an outcome you want to avoid. Before locking in your bet, consider going through the bonus page to skim through the terms and conditions to ensure you’re not defaulting on any.
After placing your bet, you can wait for the outcome of your bet to confirm if you qualify for the accumulator boost. Most accumulator boost bonuses, including bet365’s, pay out only when the bet is resolved in your favor. If you lose your initial bet, you may have to forfeit the bonus or try again on another bet, depending on the specified bonus terms. So, it’s best to stick with probable outcomes and lower odds when using the bonus.

Accumulator boosts are my favorite kind of bonus on sportsbooks, as they offer the potential for up to 100% extra on your first parlay win. The offer has its downsides: you miss out entirely if you lose your bet, for example, and they also tend to have stringent bonus terms. If you follow the terms and stick to the approved sports and betting markets, however, getting an accumulator boost bonus shouldn’t be too challenging.
