I've just sent an email to the support, let's see how much time it will take to solve the issue, if it will be fast I will give 4/5 stars on my blog.
Hello Faneagle, you are currently playing on the 10 free credits which unless you win a tournament, sitngo, or play the allotted time to release the bonus, you cannot withdraw. The free credits are not put in place to play 15 minutes and then withdraw. They are to give you an experience of the website and if you win and meet the requirements they are free to withdraw anytime.
The many players that have deposited real bitcoin and litecoin can withdraw right away their deposits and winnings but the bonus has restrictions to prevent the abuse we deal with on a daily basis. Thank you for playing with us.
