Combi Boost
When your accumulator grows, so do your odds. Every accumulator with 4 or more selections comes with a built-in odds multiplier. We call it Combi Boost and it runs on its own: nothing to activate, nothing to request, nothing to claim. You see it on your bet slip before you confirm the bet.
The more selections you add, the bigger the extra. A 4-selection accumulator gives you 2% more on the final odds, a 7-selection one 10%, and one with 12 or more selections 50% on top of what you were going to win. Your stake and your risk stay the same: if you win, you collect more, and if you lose, you lose exactly what you would have without the boost.
How it works
Automatic. Build your accumulator with 4 or more selections and the boost shows up on the bet slip before you confirm. It is added to the final accumulator odds and is paid only if the bet wins.
Minimum odds 1.50. Each selection needs odds of 1.50 or higher to count. If a selection is voided or refunded, it does not count towards the multiplier calculation, and if the accumulator is left with fewer than 4 valid selections, Combi Boost does not apply.
Pure odds. Combi Boost creates no bonus balance and no wagering requirement: it is an odds increase on bets placed with real money balance. It applies pre-match and live, on every sport, and Cash Out remains available.
Key figures
The full scale
The more selections you load into your accumulator, the higher the multiplier. Here is the full scale:
An example with numbers
You build a 7-selection accumulator at total odds of 100.40 and stake 100 USD. 7 selections get a +10% boost, so here are the numbers:
That is 1,004 USD extra with the same stake and the same risk.
