A Sports first deposit bonus offer will be paid off one time only. Such an offer is only available on the first deposit a player makes with 10Bet Sportsbook.
The bonus will be granted once the initial deposit has been rolled over with odds higher than 2.00.
In order to withdraw the bonus, customers should roll over their initial deposit at least 10 times. Only Sports bets will be considered in calculating the roll over. Any other bets such as Casino, Games and Poker, for example, which are made with deposit money, will not be considered for the roll-over and will be deemed an abuse that may cancel the bonus.
In the process of fulfilling the roll-over requirements above, all wagers should be laid on any Sports bets offering odds greater than 2.00.
This offer is available with a 20 times rollover requirement prior to a withdraw to customers from the following countries: Russia, Ukraine, Moldova, Georgia, Kazakhstan, Azerbaijan, Romania, Belarus, Croatia, Armenia and Uzbekistan.
If a withdrawal is requested before the roll-over requirements are met, the bonus will be automatically cancelled and withdrawn from the customer’s account.
On completion of the required roll-over, bonus money is converted to real money and customers are given the option to use it in any way they like.
Promotions may change. Management decisions are final.
These Terms & Conditions are part of the General 10Bet Terms & Conditions.
