Yes, you can cash out at Rizk Casino. Only one of our testers was asked to upload their KYC, so this may not be needed at all - at least not for smaller deposits and withdrawals.
However, the one tester who was asked had to provide:
Passport
Utility bill
Picture related to your payment method
In the case of our tester, Natster9, he was asked to include a screenshot from his PayPal account.
If you deposit with a debit card you may however need to include pictures of your cards.
Note: Natster9's first screenshot of his PayPal account was rejected as the PayPal logo was not visible. Be sure to include the logo if you are asked to send a screenshot of yours.
