"Warning:SCAM CASINO: This casino demands numerous fabricated charges to be paid for their services. However, regardless of payments received for processing, verifying, or unblocking, withdrawals are still not carried out. We strongly recommend not to pay any fees that may be requested on top of your active balance or pending withdrawals, as this is not something that any legitimate casino would ask for."
