One of Mostbet‘s popular offers is the “Express Booster” – a special bonus for fans of betting on expresses. It gives an opportunity to get an additional increase in odds under certain conditions.

The essence of the promotion is that a player can activate a special bonus “Express Booster” when making a coupon containing four or more events. This bonus will increase the total final odds of the express, making the potential profit even more attractive.
And the more events a player includes in his express, the higher bonus he can get under the “Express Booster” promotion. Thus, by collecting large coupons with many outcomes, you can count on a very solid improvement in the final odds.

This bonus is activated automatically when 4 or more events are added to the betting pool, each of which has odds higher than 1.2. It doesn’t matter whether you form an express from the pre-match line or live bets – the booster will be triggered in any case.
The size of the “Express Booster” is calculated using a special formula: 1 + 0.01 * (N – 3), where N is the number of events included in the express. Thus, the more outcomes will be in the coupon, the higher the bonus coefficient the player will get. The maximum possible value of the booster is 1.2.
However, it should be noted that bets made with the Express Booster may not be eligible for some other bonuses, such as the First Deposit Bonus. This happens when the odds of a non-booster express do not meet the wagering requirements. Therefore, you should always read the terms and conditions of promotions carefully to avoid misunderstandings.
