21bit Casino Deposits – Payment Methods, Limits and Step-by-Step Guide

All deposits are made at Account – Cashier – Deposit; the cashier is accessible from the account icon in the top navigation after logging in.

Funds are credited to your account balance as soon as the payment provider confirms the transaction – for most methods this is instant.

A first deposit also triggers eligibility for the welcome package; confirm that no active bonus is blocking the offer before proceeding if you intend to claim it.

Accepted Payment Methods

The cashier supports card payments, e-wallets, and major cryptocurrencies – all displayed at Account – Cashier – Deposit with current availability confirmed in real time.

How to Make a Deposit – Step by Step

The deposit process takes under two minutes from the cashier screen to confirmed credit on most methods.

Log in and click your account icon in the top navigation
Select Cashier, then choose Deposit from the menu
Pick your preferred payment method from the list shown
Enter the amount you wish to deposit
If you have a promo code, enter it in the bonus code field now – before confirming
Follow the on-screen prompts specific to your chosen method
Confirm the transaction; funds appear in your balance once the provider confirms

Depositing with Cryptocurrency

Crypto deposits require you to send funds from an external wallet to a deposit address generated in the cashier – the address is unique to your account and session.

Open Account – Cashier – Deposit and select your cryptocurrency
Copy the wallet address displayed – do not type it manually
Confirm the network matches (e.g. ERC-20 for ETH and USDT on Ethereum)
Send the exact amount from your external wallet
Allow the required number of blockchain confirmations – shown in the cashier
Do not send a different coin to the address provided – funds sent to the wrong address are unrecoverable

Crypto deposit addresses can expire after a period of inactivity; always generate a fresh address at Account – Cashier – Deposit rather than reusing a previous one.

Deposit Limits

Minimum and maximum deposit amounts are set per method and displayed in the cashier at the point of deposit; they are not published as fixed figures as they can vary by account status and payment provider configuration.

If you need to adjust your deposit limit for responsible gambling reasons, this is managed at Account – Responsible Gambling where daily, weekly, and monthly caps can be set.

Responsible gambling deposit limits are applied immediately when set and can only be decreased instantly; increases require a cooling-off period before taking effect.

Bonus Eligibility by Payment Method

Some payment methods – particularly e-wallets such as Skrill and Neteller – may be excluded from bonus qualification on certain promotions.

Check the payment method exclusions listed in the bonus terms before depositing
The cashier displays a notification if the selected method will not trigger an active bonus
Card deposits and cryptocurrency are generally eligible for all promotions
Switching method after a failed bonus application requires contacting support – the deposit cannot be reassigned retroactively

Full bonus terms, including method restrictions, are listed on our full bonus page.

Deposit Problems and Solutions

Deposit Failed or Declined

A declined deposit is most commonly caused by a card issuer restriction on online gambling transactions or an incorrect detail entered in the cashier.

Check with your bank that online gambling deposits are permitted on your card
Confirm the card details entered match those registered with your bank
Ensure the billing address entered matches your bank records
Try a different payment method if the issue is card-specific
Check that the deposit amount is within the limits shown for the selected method
Clear browser cache and retry, or switch to a different browser

If the issue persists after checking all of the above, contact our support team with the transaction reference and the error message displayed.

Crypto Deposit Not Credited

A cryptocurrency deposit that has not credited is usually awaiting blockchain confirmation – the required number of confirmations is shown in the cashier after submission.

Check the transaction status on a blockchain explorer using your transaction hash
Confirm the correct network was used – sending ETH on the wrong network results in unrecoverable funds
Allow the full confirmation window to pass before contacting support
If confirmed on-chain but not in your account, contact support with the transaction hash and deposit address

Deposit Credited but Balance Not Updated

A short delay between payment confirmation and balance update is normal – refresh the page after 60 seconds if the balance has not changed.

Check Account – Transaction History to confirm the deposit was recorded
Log out and back in to force a balance refresh
If the transaction shows as complete but the balance is unchanged, contact support immediately with the transaction ID

Deposit Limit Reached

If a deposit is rejected because a self-imposed limit has been reached, the limit is managed at Account – Responsible Gambling.

Check your current daily, weekly, and monthly caps at Account – Responsible Gambling
Limit reductions apply immediately; increases require a waiting period
Contact support if you believe a limit was applied incorrectly
