What is the 100% Acca Boost?
The 100% Acca Boost is an ongoing promotion that rewards winning accumulators by adding a percentage bonus to your cash winnings. The more legs you include (and win), the higher the boost – up to double your winnings (100%) on 20-fold accas.
The boost applies to specific markets (such as Full Time Result, BTTS, spreads, money lines, totals and certain tennis/MMA markets) across a huge list of qualifying leagues and competitions. It’s designed for punters who already love building accas and want extra upside when they land.
How the 100% Acca Boost works
1. Build a qualifying accumulator
-
Create an acca with 2 or more selections on qualifying markets:
- Soccer: Full Time Result, Both Teams To Score, Result/BTTS.
- Basketball & American Football: Spread, Money Line 2-Way/3-Way, Game Totals, 1st Half & 2nd Half spreads/totals (NFL & NBA only).
- Baseball: Run Line, Money Line, Game Totals, A Run in the 1st Innings.
- Ice Hockey: Puck Line, Money Line, Game Totals.
- Tennis: To Win Match, First Set Winner, Set Betting.
- MMA: To Win Fight, Fight Outcome.
- Selections can be pre-match or In-Play.
- All selections must be from qualifying competitions (top domestic leagues, cups, Euro competitions, World Cups, NBA, NFL, MLB, NHL, top tennis tours, etc.).
- No leg can be priced lower than 1/10, and certain enhanced/alternative markets are excluded.
2. Place your acca as normal
- Place your accumulator from your cash balance (not Bet Credits).
- You can combine different sports in the same acca as long as all selections are from qualifying markets and competitions.
3. Let the bet settle
- If your acca wins, bet365 calculates your standard payout first.
- Then they apply the relevant boost percentage based on the number of winning legs (see the Boost Breakdown Table below).
- The extra amount is paid as cash into your withdrawable balance, normally within 24 hours of the final selection settling.
4. What if a leg is postponed or void?
- If one or more selections are postponed or void, the acca is recalculated with the remaining legs and still qualifies, as long as at least two winning selections remain.
-
The boost percentage is applied based on the actual number of winning legs.
Example: an 8-fold with 7 winners and 1 postponed leg receives the 7-fold boost (15%).

| 4-folds | 7.5% |
| 5-folds | 10% |
| 6-folds | 12.5% |
| 7-folds | 15% |
| 8-folds | 20% |
| 9-folds | 25% |
| 10-folds | 30% |
| 11-folds | 35% |
| 12-folds | 40% |
| 13-folds | 45% |
| 14-folds | 50% |
| 15-folds | 55% |
| 16-folds | 60% |
| 17-folds | 70% |
| 18-folds | 80% |

The maximum extra winnings you can receive from Acca Boost on any bet is £100,000 (or currency equivalent).
Qualifying vs non-qualifying bets
Qualifying accas
- Accumulators with 2+ selections on qualifying markets listed in the T&Cs.
- Pre-match or In-Play bets on qualifying competitions (top leagues, cups and tournaments).
- Accas where all selections are priced at 1/10 or greater.
- Bets placed with cash (not Bet Credits).
Do not qualify
- Bets placed using Bet Credits.
- Bets on alternative lines/spreads/totals, Full Time Result – Enhanced Prices, Double Chance, fixed Parlay Cards, Teasers, Fixed Teaser Cards, Jackpots.
- Combination bets with built-in bonuses (e.g. Lucky 15, Lucky 31, Lucky 63, etc.).
- Accas containing markets under 1/10 or where the outcome can be void despite the event finishing.
- Any accumulator built using Bet Builder or Bet Builder+.
- Accas where a Bet Boost (enhanced odds) has been applied to the multiple itself.
- Bets that have been Cashed Out before all selections are marked as won.
If all selections are marked as winners and you then Cash Out, the Acca Boost can still be applied. Early Payouts that convert a losing acca into a winner do not receive extra boost winnings.
Pros and ideal type of player
Main advantages
- Huge upside on big accas – up to 100% extra cash.
- Works across multiple sports, ideal for weekends packed with football, US sports and tennis.
- Extra winnings are paid as cash with no extra wagering.
- Still applies even if some legs are postponed or void (boost adjusts to actual winning legs).
Best suited for
- Punters who already love accas and build multiples regularly.
- Multi-sport bettors mixing Soccer, NFL, NBA, MLB, NHL, Tennis and MMA in one slip.
- Value-seeking players who understand the risk of large accas but want the maximum possible return when they land.
Responsible betting tips
- Remember that more legs = more risk. The boost doesn’t change the probability of your acca winning.
- Treat Acca Boost as a nice extra when your bets come in, not a reason to stack unrealistic slips or chase losses.
- Set clear stake and loss limits for your accas and stick to them, regardless of how big the potential boosted payout looks.
- If betting starts to feel stressful, compulsive or out of control, use safer gambling tools (deposit limits, time-outs, self-exclusion) or seek professional support.
