BetMGM Acca Boost
Last checked:
A percentage added to the winnings of a multiple, usually rising with the number of legs. BetMGM run their own version, and what decides whether it's worth anything to you is the small print rather than the headline. Here's theirs, read from the promotion itself.
What BetMGM's terms actually say
- Restricted to selected players or races — worth checking it applies to your account before you rely on it.
BetMGM's wording, in full
“Stake up to £500 on a sports acca with at least 3 selections at 3/10 or higher per leg. Profit boost automatically added to betslip. Boost your winnings by up to 200% extra. Number of selections determines boost percentage: 3 legs = 3%, 4 legs = 5%, 5 legs = 7%, 6 legs = 10%, 7 legs = 12%, 8 legs = 15%, 9 legs = 20%, 10 legs = 25%, 11 legs = 35%, 12 legs = 45%, 13 legs = 50%, 14 legs = 60%, 15 legs = 75%, 16 legs = 100%, 17 legs = 125%, 18 legs = 150%, 19 legs = 175%, 20 legs = 200%. Selected players only. Min odds: 3/10 per leg. Max stake: £500. Max win: £250k per boost. Cannot be used with other offers including free bets and odds boosts. If any selection is postponed or voided, boost applies but percentage reflects actual number of winning selections. Cashed out or voided bets do not qualify.

Things worth knowing about acca boost
- The boost applies to returns, not to each price
- A 50% acca boost doesn't lengthen your selections — it adds a percentage to what the multiple pays if every leg lands. One losing leg and the boost is worth nothing.
- Minimum legs and minimum odds both matter
- Most boosts need four or five legs before they start, and set a minimum price per leg to stop people stacking odds-on shots. Both are in the terms below.
- There's nearly always a cap
- The headline percentage is the maximum, and the cash value of the boost is usually capped too. A big percentage on a small cap is worth less than it looks.
