Combo Boost
When your parlay grows, your odds grow too.
Every parlay you build with four or more selections comes with a built-in odds multiplier. We call it Combo Boost and it runs automatically: nothing to activate, nothing to claim, nothing to ask for. You see it on your Bet Slip before you confirm your bet.
The more selections you add, the bigger the multiplier. A four-selection parlay gets you two percent extra on the final odds. A seven-selection one, ten percent. A twelve-selection one, fifty percent on top of what you were going to win.
Each selection needs to have odds of 1.50 or higher to count toward Combo Boost. It doesn't change your bet, your stake, or your risk. If you win, you just collect more. If you lose, you lose exactly what you would have lost without the boost.
No fine print to dampen the flavor of your parlay.
How it works with an example
You build a seven-selection parlay at total odds of 100.40 and stake 100 USD. Here are the numbers:
| Without Combo Boost | With Combo Boost | |
|---|---|---|
| Parlay odds | 100.40 | 110.44 |
| Stake | 100 USD | 100 USD |
| Winnings if you hit | 10,040 USD | 11,044 USD |
| Combo Boost extra | — | +1,004 USD |
The full scale
The more selections you load into your parlay, the higher the multiplier. The full scale is this:
| Selections | Boost extra |
|---|---|
| 4 | +2% |
| 5 | +4% |
| 6 | +7% |
| 7 | +10% |
| 8 | +15% |
| 9 | +22% |
| 10 | +30% |
| 11 | +40% |
| 12 or more | +50% |
Terms & Conditions
Who can participate
Combo Boost is available to all users with an active Betamina account. No additional registration or manual activation required. The promotion is permanent and applies automatically to every bet that meets the conditions.
When the boost applies
Combo Boost applies to parlay bets with four or more selections where each selection has odds of 1.50 or higher, in both pre-match and live markets. It applies to every sport available on the platform.
How the boost is calculated
The multiplier is added to the final parlay odds and applies only if the bet wins. The boost is shown on the Bet Slip before you confirm the bet.
If a selection is refunded or canceled, that selection does not count toward the multiplier calculation. If the parlay ends up with fewer than four valid selections, Combo Boost does not apply.
What bets it does not combine with
Combo Boost does not apply to System bets (Trixie, Yankee, Canadian, Heinz, Patent, Lucky 15, Lucky 31, Lucky 63 and variants). It also does not combine with Freebets, Early Payout, or bets flagged as Enhanced Odds on individual banners.
Cash Out remains available for bets with Combo Boost applied.
General rules and maximum winnings
Maximum winnings per bet are set by Betamina at the platform level and also apply to bets with Combo Boost. If the boosted payout exceeds that limit, Betamina will pay up to the maximum allowed.
Combo Boost does not create bonus balance, does not require additional rollover, does not block withdrawals, and does not affect wagering requirements for other active bonuses. It is a pure odds boost on bets paid with your own balance.
Betamina reserves the right to modify the terms of the promotion, change the multiplier scale, or discontinue it with prior notice on this same page. Changes do not affect bets already confirmed before the adjustment.
Bets detected as systematic abuse of the boost (arbitrage patterns, coordination across accounts, multi-accounting, automated use) may be canceled in accordance with Betamina's General Terms. The original stake is returned to the player's balance.
