What is 321 Crypto Casino?

321 Casino is a Bitcoin Casino with numerous exciting features. The casino offers a blockchain-related platform where players can gamble using Bitcoin and other cryptocurrencies. Though 321 Casino is relatively new, it is slowly becoming a go-to crypto gambling site because of its exciting features, including games from reputable gaming software developers like BetSoft, Evolution Gaming, Playson, Evoplay, etc.

In addition, 321 offers exciting bonuses to new and existing players. When you register at the casino, you are eligible for a 100% first deposit bonus up to 5000 uBTC + 15 free spins. The Casino is also owned by Rok n Rolla Systems N.V., a casino brand licensed by the Curaçao Gaming Authority, one of the highly revered online gambling regulators worldwide.

Altogether, 321 Crypto Casino is a top online casino for beginners and experienced gamblers. It offers an exciting gambling experience across its mobile and desktop sites. However, on the downside, the casino restricts players in many locations, including the US. Similarly, the casino offers only crypto payment methods, and its bonuses are limited.

321 Crypto Bonus Program

Welcome Bonus 100% First Deposit Bonus up to 5000 uBTC + 15 free spins
Wagering Requirements 35x in 30 days
Other Bonus offers/promotions 120% second deposit bonus up to 5000 uBTC + 25 free spins; 80% third deposit bonus up to 5000 uBTC + 10 free spins
VIP Program None


  • Generous welcome bonus
  • Low minimum deposit
  • Live casino bonus


  • Medium-high wagering requirements
  • No VIP program or existing player rewards

At 321 Crypto Casino, you’ll find a decent number of bonuses and promotions that help you boost your winning chances.

However, the casino’s bonuses are more tilted toward new players than existing ones, which makes the bonus offers limited compared to major competitors.

For instance, new players can enjoy a welcome package up to 15,000 uBTC + 50 free spins across the first three deposits after registering a 321 Bitcoin Casino account. On the other hand, existing players do not have dedicated bonuses but can enjoy the additional deposit bonuses if they were not initially claimed after the first deposit.

Unfortunately, there is no VIP program or other bonus offers for existing players. So you won’t find perks like cashback, tournament prizes, and loyalty rewards at 321 Casino.

All the casino’s bonuses have a 35x wagering requirement that must be completed in 30 days. That means you must play with your bonus money plus deposit 35 times before you can withdraw your winnings. The wagering requirement is relatively high compared to other casinos like Lucky Block or Wolfy Casino (with zero wagering requirement).

Additionally, a minimum deposit of 250 uBTC is required to qualify for the casino’s bonuses, and bonuses are not transferable.

To make the most of your bonuses, we recommend reading the 321 Crypto Casino bonus terms and conditions before depositing money and activating a bonus offer.

We give a detailed breakdown of the bonus program below.

Welcome Bonus Offer

New players at 321 Casino can opt-in for a welcome package up to uBTC 15,000 plus 50 free spins after creating an account and making the qualifying deposit of 250 uBTC.

However, you must enter the correct bonus code when making a deposit. For instance, the casino website states you must click the “1STDEP.100” button on the promotions page to get a 100% first deposit bonus up to 5,000 uBTC plus 15 free spins.

You can also enjoy bonus offers for your second and third deposits at the casino. All the bonuses have different percentages but similar terms & conditions and maximum amounts, as highlighted below.

  • The first deposit can activate a 100% deposit bonus up to a maximum of 5000 uBTC + 15 free spins
  • The second deposit can trigger a 120% deposit bonus up to a maximum of 5000 uBTC + 25 free spins
  • The third deposit can activate an 80% deposit bonus up to a maximum of 5000 uBTC + 10 free spins.

Existing Customer Promos

Apart from the deposit match bonus for the player’s second and third deposits at 321 Crypto Casino, there are no other existing customer promos at the time of writing.

We also discovered during our 321 Crypto Casino review that it offers no VIP program, so there are no rewards or incentives for committed players.

321 crypto casino has thousands of slots, casino games, and live casinos. You can try all the games in the demo version to see if you like the game, and it’s worth betting your money. The game categories are distinct and are filtered based on the software provider. The truth is that you won’t find the top providers, but the game variety is decent.

Slots are divided into three large categories: All Slots, Megaways, New Slots. You will find Betsoft’s ‘Gold Tiger Ascent’ and ‘Take the Kingdom’. In the Megaways section, Playson slots such as ‘Buffalo Power’, ‘Legend of Cleopatra’, and ‘The Fruit’ are available.

Table games fans will find all their favorite classic games with their variations. We singled out American Roulette 3D, Blackjack Lucky 7, and Caribbean Hold’em. If you find yourself having a hard time spotting your go-to game, you can either filter the casino games by clicking on one of the three groups: Table games, Top games, Scratch Cards, or by providers.

Live Casino

The options in the live casino are more limited, but all games are offered by three notable software companies that excel in the live casino industry. The top one is Evolution games, followed by Ezugi and Super Spade. At the moment, the live casino library consists of 54 games: classic games and their variations as well as new types of games. Watch a demo and then play for real: baccarat, roulette, blackjack, poker, dream catcher, football studio, and more.

Provably Fair Games

All the games at the casino are not certified by the e-Commerce and Online Gaming Regulation and Assurance Agency (eCogra) to be provably fair. However, they are from reputable software developers like Evolution Gaming, Evoplay, BetSoft, Playson, etc.

We discovered that 321 Casino offers low house edge and responsive gameplay to offer an exciting gambling experience and also make winning easy for players.


Are there pokies in 321 Crypto Casino? Yes, the casino features over 900 video pokies for players who want access to a variety of pokies machines. Interestingly, the pokies have different titles and game types across the classic and modern eras, making them suitable for both young and old players.

321 Casino pokies are also developed by tested and trusted software providers, especially Evoplay and Evolution Gaming.

Game Fairness & RNG

321 Casino uses blockchain technology with a verified RNG system to ensure winnings are random and fair – whether you’re playing slots, table games, pokers, or live dealer games.

That means you can play your favorite games and get fair and transparent results.

Game Providers

As stated earlier, 321 Crypto Casino partners with reputable game providers to offer its players high-quality and fair games with high return-to-player (RTP) ratios.

You’ll find games from 14 tested and trusted developers at 321 Bitcoin Casino. These include;

  • Evoplay
  • Playson
  • Evolution Gaming
  • BetSoft
  • Booming Games
  • Playstar, etc.

Mobile Gaming

If you prefer to play on your mobile or tablet, 321 crypto casino is optimized for mobile casinos. The mobile version is compatible with both Android and iOS operating systems. At the moment, no 321cryptocasino app has been designed that you can download. If the casino grows more soon, it is likely to develop a mobile app.

Withdrawal Options

All withdrawal requests are processed in 12 hours, which is a lot compared to other crypto casinos. The casino has an Express Cashout Club promising instant cashouts. You can contact customer service to see whether you are eligible to become a member of that VIP club.

The minimum deposits and withdrawals are 250 uBTC. Maximum deposits and withdrawals are 100000 uBTC. Before requesting a withdrawal, you must wager your deposit at least once. If you only play casino table games, you will have to wager your deposit money 10 times.

It’s important to know that you can only withdraw money in the same cryptocurrency you deposited. For example, you can’t deposit BTC and cash out in ETH.

BTC Units Used in 321 Crypto Casino

The BTC unit for deposits and withdrawals in 321 Casino is uBTC. Note that this is different from the popular mBTC that is common at many Bitcoin casinos.

For context, 1 uBTC is equivalent to 0.0001021 BTC, and 1 mBTC is 0.001 BTC at the time of writing. To make conversations easy, 321 Casino has a live uBTC to USD converter. Currently, 1 uBTC equals 0.03 USD using the 321 Crypto Casino converter.

Security and License

License Curaçao (CGCB)
Established 2021
Safety proof Licensed Casino, RNG System, Part of the Curaçao Gaming Authority, SSL Encryption
Safety features Offers Responsible Gaming (Self-Exclusion, Time-Off, External Help)


  • SSL encryption
  • Responsible gambling


  • No provably fair games
  • Mentions Curaçao licence but does not show it on the website

321cryptocasino caters to the safety of its players with a series of measures and certifications it has taken to date. Let’s start with the most basic: the 321cryptocasino operates under the jurisdiction of Curaçao Gaming. At least this is what it states on its FAQ page; however, there is no mention of such licence on the footer of the website where one can usually find such information, nor is there any link on the FAQ mentioning the licence. We are therefore sceptical of this actually being true and suspect it might have either expired or just never existed.

A remarkable casino interested in maintaining a healthy relationship with its players should provide them with the sources to turn to in case of gambling addiction. So 321Crypto Casino offers access to useful websites such as the well-known BeGamble.org.

There is a Random Number Generator (RNG), but no provably fair games are available. We could say that these provably fair games go hand in hand with the term crypto casino. For this reason, when players hear that a crypto casino does not have this software, then they are likely to be discouraged from registering.

Customer Support

Support 24/7 customer support through email, FAQ section
Languages English, German, Spanish, Finnish, French, Polish, Portuguese, Russian, Turkish, Chinese


  • Contact form
  • Extensive FAQ


  • Unknown average response rate
  • No live chat

Before signing up for a new casino, you should always find information about customer service. A collaborative team of representatives can instantly solve any problem you face.

321cryptocasino has an extensive FAQ section in which, as a new player, many of your questions will be answered. However, any setback may occur during the game or the deposit and withdrawal process. The only way to get in contact with casino representatives is either by sending an email to [email protected] or by clicking on Support/Contact where you will be redirected to a contact form in which you can describe your issue.

321 Crypto User Experience

The user experience at 321 Casino is seamless via its website and mobile casino. From the first visit, one would notice the website’s simple and clean design that makes navigation easy.

The casino site has a basic theme with a simple interface. Games are also well categorized and properly labelled into Slots and live casino games. Players who want games from specific providers have the option of choosing their favorite provider and playing only their games.

Beyond the design, the registration process on 321 is pretty straightforward. The casino requires no KYC during registration, so all you need to do is enter your basic information and register an account with a click. You can also use the built-in currency converted to determine how much you want to deposit or withdraw.

When playing games, the casino site offers high responsiveness to swipes or taps. The live casino section also has a fast load speed, making it easy for live dealers to boost winning chances.

However, some Bitcoin casinos allow users to buy cryptocurrencies directly from their websites when depositing funds, but 321 Casino doesn’t have this feature.

Overall, the crypto exchange or marketplace for buying and exchanging cryptocurrencies is the only notable missing feature at 321 Crypto Casino.

Mobile Availability

Another impressive thing about 321 Casino is its support for desktop and mobile devices. Currently, the casino doesn’t have a dedicated mobile app for Android and iOS devices. Instead, it has a mobile-optimized casino site for smartphones.

Once you launch the website on your mobile phone, the site automatically adjusts to the screen size of your device. Interestingly, the mobile casino site is speedy and responsive, making it easy to play on the go.

The best part is that the mobile casino site requires no downloads on the Google Play Store or Apple App Store. Neither does it require extra space on your device.

How Does 321 Crypto Casino Compare to Wolfy Casino and BitCasino

Below, we review how 321 Casino compares to two major competitors, Wolfy Casino and BitCasino

Game Selection

Wolfy Casino has 8,300+ games in its gaming lobby. These include popular casino games like slots, table games, live dealer games, progressive jackpots, poker, and sports games.

BitCasino offers 2000+ games across the same gaming categories. The gaming options include slots, blackjack, roulettes, live dealers, etc. But it provides no sportsbook.

Like BitCasino, 321 Crypto Casino has no sportsbook, and it offers 1000+ games, meaning its game collection is smaller compared to the other two casinos.


Wolfy Casino holds a license from the Curaçao Gaming Authority, and it employs high-level encryption technology to protect customers’ funds and data. The casino also has a compulsory KYC.

The Curaçao Gaming Authority also regulates BitCasino and 321 Crypto Casino. Both casinos use SSL encryption to secure their websites. However, while BitCasino has mandatory KYC, 321 Casino allows players to sign up without identity verification.

Payment Methods

On Wolfy Casino, payments can be processed using 11 cryptocurrencies and 4 fiat currencies. Transactions are also completed between 24 hours for crypto and 2 – 4 days for fiat payments. In addition, the casino’s minimum deposit and withdrawal amount is $20 or its equivalent in other currencies.

BitCasino supports only cryptocurrency payments. With no fiat support, the casino’s payment options are limited. The minimum deposit is 0.25 mBTC or its equivalent using another crypto.

Players can process payments on 321 Casino using 14 cryptocurrencies only. The casino’s payment methods are limited since it doesn’t support traditional currencies. The minimum deposit amount is 250 uBTC, and the minimum withdrawal is 800 uBTC.

Customer Support

Wolfy Casino offers 24/7 customer service in 8 languages; English, German, Greek Norwegian, Finnish, Canadian English, French, and Japanese. However, support is available via live chat and email only.

BitCasino and 321 Crypto Casino also offer 24/7 customer support. BitCasino support is available in 12 languages, while 321 Casino support is available in 11 languages. Both platforms provide support via email and live chat.


Wolfy Casino has a welcome package worth $1000 for new players. The welcome offer has no wagering requirement but must be used entirely on games within the stipulated period.

BitCasino doesn’t have a welcome bonus. Instead, players are encouraged to take advantage of its VIP program.

321 Crypto has a welcome package up to 15,000 uBTC plus 50 free spins for new players. The casino also has a 35x wagering requirement that must be completed within 30 days.

Overall, 321 Crypto Casino and BitCasino are close competitors. 321 Casino offers the best welcome bonus package and competitive customer support. However, Wolfy Casino stands head and shoulders above the two other casinos because of its diverse payment methods and zero wagering requirement that make it a more favorable casino choice for the average player.
