1. What Is an Accumulator Boost?
An accumulator boost (also called an ACCA boost) increases your potential payout by a percentage when you place a multi-leg bet (e.g., 4+ legs). The % boost usually scales with more legs. Always check the minimum odds per leg and eligible markets.

3. How ACCA Boosts Work (Example)
Suppose you place a 5-leg football accumulator with combined decimal odds of 7.50 and a €20 stake. If the site offers a +7% boost for 5 legs and your bet wins:
| Item | Calculation | Result |
|---|---|---|
| Base Winnings | €20 × 7.50 | €150.00 |
| Boost Amount | €150.00 × 7% | €10.50 |
| Boosted Return | €150.00 + €10.50 | €160.50 |
Numbers above are examples. Operators may credit boosts as cash or bonus funds. Check payout type and any wagering rules.
4. Key Terms to Check
- Minimum legs required for the boost to apply (e.g., 4+).
- Minimum odds per leg (e.g., 1.20 / 1.30+).
- Eligible markets (football only? pre-match + in-play?).
- Cash-out impact — usually voids the boost.
- System bets (Yankees, Heinz) often excluded.
- Payout type — cash vs bonus funds and any wagering.
- Regional rules — see our Legal Overview.

6. Strategy Tips to Maximise Boosts
- Target core leagues (Premier League, LaLiga, Serie A, Bundesliga, UCL) where information and pricing are stable.
- Mind the leg count — add legs until the next boost tier, but avoid low-value selections.
- Compare markets (1X2 vs Over/Under vs handicaps) for the best probability/price mix.
- Use bankroll management and value betting principles.
- Check cash-out rules; early cash-out usually cancels the boost.
- Optimise deposits with fast, low-fee methods: PayPal, Skrill, Neteller, Visa.
