A Bet Builder bet offers more possibilities than a normal combi bet. You can place several tips on a specific event or combine it with other matches. You can even combine Bet Builder bets.
But take note: If one tip of your Bet Builder bet is voided, the whole Bet Builder bet itself will be voided too - regardless of the outcome of the other tips.
How can you place a Bet Builder bet? Simply choose the desired event, click on the tab "Bet Builder" in the bet overview and select the tips you want to place.
