A Costa Rica-licensed casino built for fiat and cryptocurrency players alike.
18+ · Last updated: 4 Sep 2026
21bit Casino runs on a library of more than 3,000 games from nineteen studios, including BGaming, Pragmatic Play, NetEnt and Evolution. The lobby covers slots, live dealer tables, table games, jackpots and crash titles such as JetX. New players start with a welcome package worth $900 plus 250 free spins, spread across the first five deposits. Payments run through cards, bank transfer and ten cryptocurrencies, with deposits starting from as little as €20 or the equivalent in crypto.
"$900 + 250 Free Spins over first five deposits (also referenced elsewhere as $3,000 + 100 Free Spins over first three deposits)"
The headline welcome offer at 21bit Casino totals $900 plus 250 free spins, split across a player's first five deposits. The first deposit carries a 100% match, the second a 75% match, the third 100%, the fourth 125%, and the fifth 150%. Each stage is only unlocked once the prior deposit and its wagering are accounted for, so the full package is built up over time rather than paid in one lump sum.
An alternative version of the welcome package appears on some pages as $3,000 plus 100 free spins, spread across three deposits instead of five: a 100% first deposit bonus, a 125% second deposit bonus with 25 no-wager free spins, and 75 no-wager free spins on the third deposit. Both versions are aimed at new players only, and players from Sweden are excluded from the welcome bonus entirely.
Whichever version applies, the offer is designed to reward continued depositing rather than a single top-up. Players should check which package is active on their account page before assuming either figure applies automatically.
Spread across first five deposits
Get Started45x wagering applies unless stated otherwise.
The default wagering requirement across 21bit Casino promotions is 45 times the bonus amount, unless a specific promotion states otherwise. Separately, a general anti-fraud rule requires any deposit to be wagered three times before that money becomes eligible for withdrawal, and if several deposits are made without gameplay in between, the wagering applies to the combined total.
Bonuses are non-sticky. For deposit bonuses, real money is played first and bonus money afterwards; for no-deposit bonuses, bonus money is used first. If the bonus portion is lost, the bonus itself is cancelled. A cap also applies to non-welcome deposit bonus winnings, which are capped at five times the bonus issued, and no-deposit bonus winnings are capped at figures such as $50 or the local equivalent.
Bonuses expire seven days after being credited if wagering is not completed; unmet wagering voids both bonus and any winnings, leaving only the original real-money balance. Only one bonus may be active at a time, and only one bonus is allowed per household, device, email, phone number or payment method. Maximum bet while a bonus is active is capped low, around $7.50 or its currency equivalent, and exceeding it can void winnings.
A long list of slot titles is excluded from bonus play, covering many popular jackpot and branded games. Abuse rules also flag behaviour such as depositing without real-money play, switching to low-variance games near the end of wagering, or using multiple accounts to claim duplicate offers.

Reload bonuses, lotteries and daily surprises.
Beyond the welcome package, 21bit Casino runs a Weekend Reload worth 40% up to $150, available every Saturday and Sunday with the code WEEKEND. Tuesday's Book Club lets players choose their own number of free spins with a Tuesday deposit, and Daily Surprise Spins reward any deposit of $20 or more with a mystery reward delivered the next day.
The Top Slots Super Offer runs weekly, giving free spins on featured pokies via the codes TOP40 or TOP100. The Fortune Cruise Lottery holds weekly prize draws, and Cyber Bonanza is a jackpot feature offering three separate large prizes. A Bonus Shop also lets players exchange loyalty points or cash for boxes ranging from a Starter Box with up to 35 free spins to a Premium Box with up to 155 free spins.
All Bonus Shop boxes carry 45x wagering, and only three bonuses can be claimed from the shop per day. As with the welcome offer, Sweden is excluded from every bonus and promotion listed here, including the Bonus Shop.

The 21bit Loyalty Program, also called the VIP Club, awards one loyalty point for every $30 wagered on slots. The ladder has eight ranks starting from New Investor, and points never expire once earned. Climbing the ranks unlocks free spins bundles, access to the Bonus Shop, and tailored VIP rewards such as cashback and extras at higher tiers.
Higher-level players gain faster withdrawals, higher deposit limits, exclusive tournaments and a personal VIP manager. Level upgrades are processed once a month, during the first week, rather than instantly as points accumulate. Players can also reach VIP status immediately by making a first deposit of $3,000 or more.
Anyone holding VIP status at another casino can request equivalent access at 21bit by emailing proof of that status to support. This gives established high-value players a route into the higher tiers without starting from the bottom rank.
Requirement: starting level
21bit Casino combines a large game catalogue with support for both traditional and cryptocurrency payments. Over 3,000 games sit alongside ten supported cryptocurrencies including Bitcoin, Ethereum and USDT, with no upper deposit limit imposed on crypto transactions due to their decentralised processing. Encrypted connections are described as offering blockchain-level protection for account and transaction data.
The platform runs entirely in-browser, with no downloads needed on desktop or mobile. Support is available 24 hours a day via live chat and email, which matters given the range of promotions, wagering rules and verification steps a player may need help with.
The loyalty program adds a long-term incentive layer, with points that never expire and eight ranks to climb. Combined with weekly reloads, a lottery, and a Bonus Shop, there is a steady stream of smaller offers beyond the initial welcome package.
From registration to first deposit in a few steps.
Signing up starts with creating a new account, or logging in if one already exists. During registration, players provide their date of birth alongside valid ID confirming they are 18 or older, plus their full legal name, residential address and a working email address. This information forms the basis of the account before any deposit is made.
Before a first withdrawal, further checks apply. Government-issued photo ID such as a passport, driver's licence or national ID card is required, along with proof of current address like a utility bill or bank statement. A photo or screenshot of the credit card used, front and back, may also be requested if a card was the deposit method.
Once registered, the minimum deposit across the site is €20 or the equivalent in another supported currency or cryptocurrency. Players depositing with Bitcoin must complete age verification with valid ID before any bets using BTC are unlocked. Additional documentation can be requested at any stage before an account is considered fully verified.

Nineteen studios power the 21bit catalogue.
The 21bit catalogue is organised into six main categories: slots, live casino, table games, jackpots, crash games and game shows. Slots make up the bulk of the library, sourced from providers such as BGaming, Pragmatic Play, Spinomenal and Play'n GO, and include mechanics like Hold & Win and Megaways.
Live casino tables are streamed by Evolution, Pragmatic Live, Winfinity, Platipus and ICONIC21, covering roulette variants such as Immersive Roulette and Auto Roulette 500X, plus blackjack tables including VIP Blackjack Emerald and Gravity Blackjack. Named live shows include Crazy Coin Flip and Gonzo's Treasure Map.
Jackpot titles such as Fat Panda, Bonanza Billion and Royal Kitties sit apart from the regular slot pool, and progressive jackpot wins are paid out in full without counting toward standard withdrawal limits. Crash games, including JetX, round out the faster-paced side of the lobby.
No app, no download, browser-based play.
21bit Casino is built for mobile browsers, with every game optimised to run without a separate app or download. Players log in directly through their phone or tablet browser and reach the same lobby, promotions and account tools as on desktop.
Instant play applies across the platform, meaning games load directly rather than requiring installation, and live streaming for the live casino section works the same way on mobile as it does on a computer. This keeps the crash games, live tables and slots equally accessible on the move.
Because there is nothing to install, storage space and device compatibility are less of a concern than with app-based casinos. The trade-off is a dependence on a stable internet connection for live dealer sessions and streamed content.
21bit Casino accepts Visa and MasterCard, with deposits between €10 and €4,000, plus Bank Transfer with a minimum withdrawal of €20 and a maximum of €10,000, processed over roughly three business days. Bank transfer payouts in USD are not available. Ten cryptocurrencies are supported for both deposit and withdrawal, including BTC, ETH, LTC, USDT, XRP, TRX and BNB, each with its own minimum deposit and no deposit fee.
Crypto transactions are converted using real-time rates via Coinbase Converter at the moment of the transaction, and direct exchanges between crypto and fiat are not supported. Because crypto transactions are decentralised, no upper deposit limit is imposed on them, unlike card and bank transfer methods.
The main currency is EUR, though the platform also supports AUD, MYR and several crypto denominations. Deposits site-wide start from €20 at minimum. Any Paysafe transaction is processed by the payment agent Tronabriz Limited, and deposits must come from a payment account registered in the player's own name; third-party deposits result in confiscated winnings and return of the original deposit to its rightful owner.

Daily, weekly and monthly caps by currency.
Withdrawal limits at 21bit Casino are set daily, weekly and monthly. In euros, the daily cap is €1,000, the weekly cap €5,000 on a rolling seven-day basis, and the monthly cap €15,000, resetting on the first of each month. Equivalent limits apply in other currencies, such as $1,500 AUD/NZD daily and $8,000 AUD/NZD weekly.
Minimum withdrawal is €20 or its equivalent, including a crypto equivalent available on request. Withdrawals are aimed to be processed within 72 hours of approval, though the approval step itself can take up to 72 hours on top. Winnings from a player's first three deposits are capped at €5,000 total regardless of bonus use, with any excess forfeited, though this cap does not restrict withdrawal of deposited funds that were never previously withdrawn.
Balances exceeding €15,000 may be paid out in monthly installments of up to €15,000 each until the full amount clears. Accounts inactive for 12 consecutive months incur a monthly dormancy fee of €25, or the remaining balance if lower, until the account is reactivated or the balance reaches zero.

Against typical crypto-friendly casinos, 21bit Casino stands out for the breadth of its cryptocurrency support, with ten coins accepted and no upper deposit ceiling on crypto transactions, something fewer competitors offer across the board. Its game count of over 3,000 titles from nineteen providers is also on the larger side for a site of this type.
Where it is more conservative is in withdrawal limits and bonus terms. The 45x wagering requirement is on the higher end compared to some rivals, and the first-three-deposits winnings cap of €5,000 is a meaningful ceiling that not every competitor imposes. The restricted-country list is also broader than average, spanning multiple EU member states alongside the usual exclusions.
For players focused on crypto flexibility and library size, 21bit compares favourably. For those prioritising low wagering requirements or the lowest possible withdrawal caps, it sits in the middle of the field rather than at the front.

Documents needed before your first withdrawal.
Verification is required before any withdrawal request is completed, and separately before a player can bet using Bitcoin, where age verification with valid ID must be submitted first. The standard document set includes a government-issued photo ID such as a passport, driver's licence or national ID, plus proof of address such as a utility bill or bank statement.
Proof of the payment method used may also be requested, typically a photo or screenshot of the credit card front and back, or an e-wallet screenshot. Documents must be in Latin or Cyrillic script; otherwise, video verification is required, where the player holds their ID and states their name and date on camera.
Withdrawal requests stay pending until every required verification step is complete. If 21bit cannot reach a player by phone or email within two weeks of a withdrawal request, the account is locked and the withdrawal is cancelled. Once an email address is verified on the account, it cannot be changed afterward.
Enhanced checks can include live phone verification alongside standard document review. If a player is later found to be underage, the account is closed, transactions are voided, genuine deposits are refunded, and any winnings already withdrawn must be reimbursed.
Pending time: up to 72 hours for approval
Withdrawals go back to the deposit method
Regulated by the Tobique Gaming Commission.
21bit Casino is operated by Novatrix SRL, registration number 3–102–893958, headquartered in Costa Rica. The site holds e-gaming licence No. 0000002, issued by the Tobique Gaming Commission. Payment processing runs through the payment agent Tronabriz Limited, and disputes are escalated through EGIS, which operates under Tobique Gaming Commission regulations.
The minimum age to play is 18. A broad list of restricted countries applies, covering territories across multiple continents, and Sweden is separately excluded from all bonuses, promotions, VIP programs and loyalty point exchanges even where real-money play may be permitted.
All disputes with 21bit Casino are resolved exclusively through arbitration in Costa Rica, which means players do not have recourse to courts in other jurisdictions. This arbitration clause sits alongside the Tobique Gaming Commission licence as the primary regulatory and dispute framework governing the site.
Australian Communications and Media Authority (ACMA)
In Australia online casino games are prohibited under the Interactive Gambling Act 2001, enforced by the ACMA, which blocks unlicensed sites; sports betting is licensed by the states and territories. BetStop is the national self-exclusion register. The legal age is 18.
Minimum age: 18+ · ACMA website
21bit Casino provides several tools for players to manage their spending and playtime, including a Deposit Limit, Loss Limit and Wager Limit that can be set on the account. These sit alongside a Cooling-Off Limit, which can be applied for one week, one month, three months or six months to pause activity temporarily.
For longer breaks, a Self-Exclusion Limit is available for six months, nine months, one year, or permanently. Once set, the account is immediately disabled, excluded from all promotions for the chosen period, and blocked from further deposits or play, though a manual withdrawal via support remains possible during self-exclusion.
Active self-exclusion does not remove the requirement to complete standard verification procedures if a withdrawal is requested. These controls sit alongside the operator's 18+ minimum age policy as part of the overall approach to player protection.
Gambling Help Online · BetStop
Live chat and email, available around the clock.
Support at 21bit Casino is available 24 hours a day, seven days a week, through live chat and email. The support email address is [email protected], which handles account, payment and verification queries alongside the live chat option.
Given the number of active promotions, wagering conditions and verification steps described elsewhere on the site, players are likely to need support most around bonus eligibility, withdrawal delays pending KYC, or clarifying which welcome package applies to their account.
No specific list of supported support languages is published, so English-speaking players can expect service through the standard live chat and email channels without a separate stated language guarantee.
21bit Casino's strengths centre on its game library, crypto flexibility and loyalty structure. Over 3,000 titles from nineteen providers, ten supported cryptocurrencies with no deposit ceiling, and a loyalty program with points that never expire all add tangible value for a player who plans to stay active on the platform for a while.
The drawbacks sit mostly in the fine print. The 45x wagering requirement, the €5,000 cap on first-three-deposit winnings, and the low maximum bet allowed during an active bonus all require careful reading before opting in. The two-week KYC response window and the fixed monthly dormancy fee after twelve months of inactivity are also worth noting in advance.
Taken together, the casino rewards players who read the terms closely and manage their bonuses deliberately, rather than those looking for the simplest possible no-strings offer.
21bit Casino positions itself as a crypto-first casino with a large, varied game library and a loyalty program built for the long term. Ten supported cryptocurrencies, no crypto deposit ceiling, and over 3,000 titles from nineteen providers make it a reasonable option for players who want flexibility in how they fund their account and what they play.
The terms attached to bonuses and withdrawals require attention. A 45x wagering requirement, a €5,000 cap on winnings from the first three deposits, and a broad restricted-country list are all factors a prospective player should weigh before depositing. Verification is mandatory before any withdrawal, and the two-week response window for KYC checks is worth keeping in mind.
Overall, 21bit Casino suits players comfortable with crypto payments, willing to read bonus terms carefully, and who value a large game selection and a loyalty ladder over the lowest possible wagering requirement.
