Extra Odds is when an event bet rate is presented to you higher than usual as a special campaign. For example, if an event with a rate of 1.50 was offered to you as an extra campaign with 10.0, you can make your bet over this 10.0. The maximum amount you can bet may vary depending on the campaign conditions. The extra winnings you earn will be credited to your account as a bonus.
For example, with the real money in your account, you bet on a match of 10 TL and increased from 1.50 to 10.0, and you won. In this case, 10 x 1.50 = 15 TL money and 10 x (10-1.5) = 85 TL bonus will be added to your account.
