Combo Booster – Double your winnings thanks to your accumulator bets!

It’s time for the final Grand Slam of the year in New York. Will Federer be able to win his 3rd Grand Slam of the year? Will Nadal be able to keep his first place position in the rankings? It’s going to be a fun few weeks!

What’s more, accumulator bets on US Open matches could be very profitable for you! For every winning accumulator bet you will be receiving a cash bonus depending on the number of selections included in your accumulator. The more there are, the bigger the bonus!

How does it work?

The Combo Booster offer will be taking place from Monday 28th of August until Sunday 10th of September 2017. This can be applied to all US Open matched offered on Winamax.fr (singles and doubles, men’s, women’s and mixed).

For every accumulator including at least 3 selections (exclusively on matches from the New York tournament) your winnings will be boosted, starting at a 5% bonus for an accumulator with three bets, up to a 100% bonus for an accumulator with 15 or more bets!

For instance, if you bet €10 on an accumulator with 12 selections with total odds of 8/1 and your accumulator wins, you will pocket €80 in winnings plus 50% x €70 (net winnings) on top thanks to the combo booster, thus boosting your winnings to a total of €115!

Details

  • Selections with odds of less than 1.10/1 are not taken into account. Thus, if you place an accumulator bet with 5 matches with 4 selections at 2/1 odds and one selection at 1.05/1 odds, your bonus will be the equivalent to a bonus from an accumulator with 4 selections.
  • System bets are not taken into account. All types of In-Play or pre-match betting are taken into account (match result, number of games etc.).
  • Qualifier matches for the US Open are not taken into account.
  • If one of your selections is cancelled, your bonus will be recalculated in order for it to correspond to the number of non-cancelled selections from the accumulator. For example, if you bet on an accumulator with 7 selections which has one of its selections cancelled, your bonus will be the equivalent to that applied to an accumulator with 6 selections.
