Bet365 Bet credits are a simple bonus system designed for new customers who sign up to Bet365 and make a deposit. Bet Credits are used for sports betting and are virtual money, you can use them to place bets just like you do with real money. Once awarded, start betting, and whatever you win becomes real money that is available for withdrawal! It is important to know that any returns made with Bet365 sign up offer and Bet Credits will exclude the stake. For example, a £10 placed will return £10 if your winning bet has been placed on Evens - in normal circumstances, you would get £20 back.
