An odds boost is a type of promotion that increases the odds for a bet you place, usually for a specific match or bet. For example, a 100% odds boost would double the base odds of your selected bet. If the odds were 2.00, it would boost them to 4.00, thereby doubling your potential winnings as well.
To use the odds boost, it has to be selected in the bet slip before placing your bet.
Important: Odds boosts have a maximum bonus winnings amount so always check the promotion terms in the Promotions tab or in your account under My promotions before placing your bet!
