What’s included. 21Bit Casino offers a first-deposit welcome package of 100% up to €500, plus 200 free spins. The free spins are credited as 20 spins per day for 10 days and are tied to a selected slot from the promo list inside the cashier/bonuses section.
How to claim (step by step). Create an account, confirm your email, and complete your profile details. Open the cashier, choose a deposit method, and deposit at least €20. Select the welcome bonus in the deposit screen (or enter the bonus code 21BITWELCOME if the cashier requests it), then confirm the deposit; the matched bonus funds are added right away, and the first batch of free spins appears in the “Bonuses” area.
Wagering requirements. The deposit match comes with a 35x wagering requirement on the bonus amount, and free spins winnings are credited as bonus funds with a 35x wagering requirement. Slot play contributes 100% toward wagering, while table games contribute 10% and some games may be excluded by the bonus rules list.
Time limit. You get 10 days to use the free spins from the moment they start dropping, and 14 days to complete wagering on the bonus balance before it expires. While wagering is active, the maximum cashout from bonus-derived winnings is capped at €5,000.
Open the sign-up page, enter your email and a password, then confirm your email link. You can finish identity checks later, but withdrawals can pause until verification is done.
You’ll see the welcome offer in the Promotions area after you log in and make an eligible first deposit. Bonus money is locked until you meet the wagering requirement shown in the bonus terms on the promo page.
Yes—games load in a web browser on desktop and mobile, so you don’t need an app. If a game doesn’t load, switching browsers or turning off an ad blocker usually fixes it.
Crypto withdrawals are typically faster once your account is verified, while bank-style payouts take longer due to payment processing steps. The cashier page shows the available methods and expected processing times for your region.
Verification commonly requires a photo ID and proof of address, and sometimes a payment-method check. Cashouts stay on hold until the documents are approved and the account details match the withdrawal request.
Use the Responsible Gaming tools in your account settings to set deposit limits, session limits, or a timeout. Self-exclusion blocks access for the selected period and support can’t remove it early.
Use live chat from the site menu for the fastest help, or send an email if you need to attach screenshots. Keep your username and transaction ID handy so support can trace the exact action.
21Bit Casino credits a 100% bonus on your first Bitcoin deposit. The bonus is capped at 1,000 mBTC and is added after the deposit is confirmed.
Up To 0.5 ETH
Every Wednesday, 21Bit Casino applies a 50% reload bonus to a single Ethereum deposit. The offer is limited to one claim per account per Wednesday.
21Bit Casino returns 10% cashback on weekend net losses across eligible games. Cashback is calculated on Monday and credited as bonus funds.
A wagering requirement is the number of times you must stake the bonus amount (and sometimes the bonus plus your deposit) on eligible games before you can withdraw bonus-related winnings. At 21Bit Casino, the playthrough is calculated from settled bets only, and different game types can contribute at different rates.
