21Bit Casino has quickly ascended to the top of the cryptocurrency gambling industry. The platform is owned and operated by Dama N.V., which itself holds a Curaçao eGaming licence. As one would expect from a crypto casino, you can use various digital currencies to facilitate near-instant and low-fee transactions.
More than 5,000 casino games await you, as well as a rewarding eight-ladder loyalty programme. So let’s check out why 21Bit Casino is much coveted among crypto-savvy players.
21Bit Casino Bonuses
21Bit Casino puts a strong focus on its welcome bonus, but once you are done with it, you will instantly be entitled to a range of other promos—reload bonuses, free spins, missions, and whatnot. To claim any bonus, just click on the “Get Bonus” button, and then you will be redirected accordingly. Let’s explore the bonus section in more detail below:
Standard Welcome Package
For your first three deposits at 21Bit Casino, you can choose between two welcome bonus options, depending on the minimum deposit you make.
Let’s start with the first one: $750 bonus + 250 free spins valid on your first five deposits:

To trigger the welcome bonus, you need to make a $10 deposit minimum. You can withdraw up to $670 from the cash bonus and $50 through the free spins bonus. The wagering requirements for the cash bonus stand at 45x, but they will vary for the free spins in each offer:
- 1st deposit: 45x
- 2nd deposit: 40x
- 3rd deposit: 35x

Daily Sunrise Spins
Players who have deposited at least once during the previous day can receive the Mystery Daily Sunrise Spins. A deposit of $20 will be enough to trigger this bonus, after which you will need to open the Mystery Box to see the hidden prize. Note that before requesting a payout, you must wager the free spins winnings 45 times, and you have three days for it.
Top Slots Super Offer
All players who make three successful deposits of at least $20 at 21Bit Casino can claim up to 100 free spins. The wagering requirements on winnings generated through free spins stand intact—45x the bonus and free spins result amount. You have three days to complete the requirements before the bonus expires.
Fortune Cruise Lottery
With each $20 deposit you make at 21Bit Casino, you can claim one lottery ticket. Collect up to five and you will enter the weekly Fortune Cruise Lottery promotion where you can get a bonus prize with 20x wagering requirements. Check your account every Saturday to see what type of bonus you have received and use it to boost your bankroll on eligible games.
Cyber Bonanza
Moving on, the Cyber Bonanza promotion includes three jackpot levels with a minimum bet requirement for participants:
- Cyber Jewel: $1
- Cyber Fortune: $3
- Cyber Trove: $5
All you need to do then is load an eligible game, make your bet, and enjoy the offer. The best aspect of it is that there are no wagering requirements attached.
Crypto Wheel
21Bit Casino seeks to keep you engaged and incentivised by offering you the chance to spin a crypto wheel with numerous prizes. To participate, you need to deposit at least 20 USDT, and all bonuses you get must be claimed the same day. Wagering requirements from any free spins you manage to obtain stand at 45x.
Tuesday’s Book Club
By making a deposit on Tuesdays, you will be able to choose the number of free spins you want to receive, so bonuses won’t come any better than this. The standard wagering requirements apply here, as in other free spins bonuses:
- 7-day validity
- 45x wagering requirements
- $5 maximum bet
- $50 maximum withdrawal
Weekend Reload
Your Saturdays and Sundays are about to get much more exciting thanks to the 40% weekend reload bonus of up to $100. Deposit at least $20 and enter the bonus code “WEEKEND” to claim the offer.
Be aware that this is a bonus valid for players who have already used the welcome bonus. Again, the wagering requirements are 45x, and the bonus is valid for 7 days upon activation.
21Bit Missions
Missions at 21Bit Casino are available for players who have made at least one deposit. Complete different achievements, such as phone verification, email confirmation, first withdrawal, installing the app, etc., and you will receive various rewards, including free spins.
Tournaments
We recommend that you consistently monitor the “Tournaments” page at 21Bit Casino, as it frequently showcases competitions that are both time-sensitive and potentially lucrative. Participating in such tournaments often requires you to make a mere minimum deposit on an eligible game, secure wins, and climb the leaderboard. Top-ranked players always get the biggest slice of the usually hefty prize pool.
Loyalty Programme
Every $20 wager you make on any slot at 21Bit will get you 1 loyalty point. Collecting points will help you climb the loyalty ladder, where each new level unlocks different free spins rewards. Moreover, you can trade the generated points for boxes with different cash prizes in the 21Bit Bonus Shop.

To access all games, simply click on the “Play” button on the homepage and navigate through all titles either by choosing a specific category or by selecting a certain provider.
The lobby features all the newly released games, and for even faster access, it stores all the games you have recently played in a separate section.

There is no general “Slots” section where all games under this umbrella are listed, but you can narrow down your choice for a game by entering a specific sub-category, including:
- Bonus Buy slots
- Jackpot slots

- Daily Drops & Wins
The list of providers powering up the slots section is as extensive as it gets, with prominent names including Pragmatic Play, Evoplay, Relax Gaming, Mancala Gaming, Quickspin, NetEnt, and Wazdan, just to name a few.
RNG Table Games
Clicking on the “Table Games” tab at 21Bit will uncover all card games, but unfortunately, even live dealer games are included here. To see all the different RNG-powered table games at 21Bit, you will need to use the “Search” bar and enter a specific game name.

Roulette games are stored in a different section, where you will find 50+ different variations—both RNG and live dealer titles.
Live Casino
As leaders in the live casino world, the likes of Pragmatic Play, Evolution, and Playtech have ensured that players have access to the most comprehensive list of live dealer games at 21Bit.
Live blackjack and roulette games are in different sections, but if you would like to give game shows, baccarat, or poker a go, you will need to navigate your way in the live game lobby through the tearch bar.
Video Poker
Finally, if you would like to refresh your online gambling experience a bit through different types of games, you can always turn your attention to the video poker section. Habanero developed the vast majority of RNG-powered video poker titles here, and notable examples of popular titles include Tens or Better 50-Hand, Joker Poker 10-Hand, Bonus Deuces Wild 50-Hand, and Aces and Eights, among others.
