Yeah, I remembered it now. That's why this "Riobet" sounds familiar to me. Regarding my experience there, I won some but I wasn't able to make deposits to cash out my winnings from free spins since I failed to gather information about them. I wish this casino could be trusted.
Can you still see your winnings on your account there? Have you checked your account balance yet? I hope you remember your login information.
I believe he won't be able to see the free spins winning amount in his account. Because there is a expire limit of the bonus balance. If a user doesn't meet the wagering requirement before the expire date then the winning amount will disappear. Welcome free spins had 7 days expired date at the time. I had posted a
screenshot here.
In their bonuses and promotions page ‘General Casino Bonus Rules’ says that
1.5 Unless otherwise stated, all Bonuses expire after 30 days from the time they are received. If the relevant Bonus Conditions are not met during this time, the bonus will be canceled.
