Swedish online casinos accept all imaginable payment methods, but the safest ones are either anonymous (private) depositing gateways that allow you to deposit and withdraw privately or time-tested, reliable gateways for legal players. In addition to traditional credit and debit cards, we would recommend you Trustly with its Pay N Play mobile payment channel, Zimpler, BankID, and Paysafecard. Anyway, keep in mind that safety starts with picking a reliable online gaming casino.
