Price Boost is when the odds for an event are presented to you higher than normal under a campaign. The maximum amount you can bet may vary depending on the campaign conditions. Earnings from the price boost will be credited to your account as a bonus.
A match has 1.50 odds normally but a 10.0 odd is offered as a price boost. In this case, your winnings will be credited in your account as 10 x 1.50 = 15 TL as withdrawable balance and 10 x (10-1.5) = 85 TL bonus.
