In promotions where your stake can be returned if a certain event happens (a goalless draw in football for example), the return is in the form of Bet Credits if they were used for the bet. You can use the Bet Credits on all the many markets that are available on the site.
Once you have met the qualifying conditions, you can use your Bet Credits to stake bets without risking your own cash. Bet Credits can be used on any sport across a wide range of markets. Any returns from bets placed with Bet Credits are added to your Withdrawable Balance, returns exclude your Bet Credits stake.
