Available Deposit and Withdrawal Methods At 21 Casino
Should 21 Casino’s layout and games entice you to sign up, you’ll be interested to know that the iGaming giant has a wide range of payment methods for customers to use should they wish to deposit. No matter the users' preference, they can choose between a few card payments or the multiple e-wallets that are readily available.
Almost all methods used to deposit can also be used to withdraw funds, minus Paysafecard, which is an option that doesn’t currently exist. Should you wish to use any of the remaining options that are readily available, all can be used. However, make sure to check the terms and conditions; they all individually have different withdrawal times.
Based on your chosen withdrawal method, we understand that when you win a jackpot, most users want to transfer funds from their casino account to their personal account.
Therefore, we need to inform all users that each withdrawal method has a different processing time. While we understand that players want their funds transferred instantly, 21 Casino has a secure process in place to ensure that all money can be transferred safely.
The wait time for each payment method is directly related to the specific process being used. For instance, e-wallets generally have faster transfer times, while wire transfers and card payments take longer due to the security protocols implemented by both the casino and the bank.
