Casinos can block winnings, but usually only if there’s a violation of terms—like using multiple accounts, bonus abuse, or providing false information. That’s why it’s crucial to verify your account and always read the rules before playing. I’ve played at kingdom casino and never had issues with withdrawals, but I make sure to follow their guidelines closely. If you play fair and stick to one account, most reputable casinos won’t give you trouble when it’s time to cash out.
