In just the last few years, Dama N.V. has established itself as one of the most active players within the online gambling community. In just the last 3 years alone, the operator has introduced close to three dozen online casinos. Among that group of casinos are a few cutting-edge online casinos that focus solely on cryptocurrencies as the site's primary banking option. One such casino is 21Bit Casino.

21Bit Casino was introduced to players in mid-2022. Both Dama N.V. and this casino are licensed and regulated by Curacao eGaming on behalf of the Curacao Government. 21Bit Casino has plenty of well-known casino siblings such as Spin Samurai, 7Bit Casino, Zoome and Jackpoty Casino. So if these top-notch crypto casinos have made an impression on you, chances are good that you'll love 21Bit Casino as well.

21Bit Bonus

21Bit Bonus and Free Spins

Normally, Dama N.V. online casinos will offer a nice variety of bonus promos. That's not really the case with 21Bit Casino. In fact, the website only shows three offers at this time if the standard referral bonus program is included.

The good news is the welcome bonus does offer some pretty good value for new customers. The website's welcome bonus covers each new customer's first four deposits as follows:

  • 1st deposit = 100% match-up bonus to a max of .0072 BTC + 50 free spins
  • 2nd deposit = 50% deposit bonus up to .0097 BTC + 50 free spins
  • 3rd deposit = 50% deposit match up to a max of .0145 BTC + 50 free spins
  • 4th deposit = 50% match up deposit bonus up to 0168 BTC + 50 free spins

In each case, all free spins will need to be directed at very specific video slots. Also, the free spins will be allocated over two days @ 25 per day. After receiving the cash bonus portion, new customers will have seven (7) to fulfill the operator's 45x (bonus and deposit) playthrough requirement.

Other than the welcome and referral bonus, the website shows one other bonus, that being a daily cashback offer. Cash rebates are only available after new customers have made and wagered their 4th deposits. The cashback rate is set at 10% of net losses. We are really vibing the fact that almost all new bitcoin casinos give players cashback bonuses - especially when the wagering requirements (5x) are pretty fair.

21Bit does offer a V.I.P. or loyalty program with additional benefits. The program has eight (8) levels and offers a primary benefit of intermittent cash bonuses that come with a 10x playthrough requirement.

Final Notes: It does appear that all playthrough requirements are focused on video slots only regardless of the bonus source. Also, bonuses are calculated based on each specific type of crypto deposit, but the amounts are always equal to the aforementioned Bitcoin calculations.

21Bit Review

When online gamblers visit a crypto-casino, they usually do so with the expectation of seeing a cutting-edge online casino. 21Bit Casino fits that description to a T. The home landing page looks tremendous with its "space-age motif." The website is very well organized and easy to navigate from a series of navigation menus located throughout each page of the website.

The site features 3,000+ online casino games from close to three dozen top online casino game software developers. Admittedly, top software developer Netent is not participating in the games library. However, other top software developers are plugged into the SoftSwiss casino platform. The most prominent names on that list would be EGT, Betsoft, Play'n Go, Yggdrasil, and Evolution GAmbing contributing live casino games.

Since this is a crypto-only online casino, some casino gamblers might view the lack of fiat currency banking options as a negative. So if you are not looking for a bitcoin casino - then yes, move on to other online casinos. But players who like to play with crypto currencies, will find themselves using an online casino that has a lot of positive attributes.

The operator does support responsible gambling initiatives, and they do use the latest in SSL digital encryption technology to protect the website and its infrastructure.

Verdict: As a new online casino website, online gamblers should proceed with caution until this online casino site has had ample opportunity to mature and build a reputation. With that said, 3,000+ games and a decent bonus program makes this website worthy of consideration from recreational online casino gamblers.


It's true that 21Bit Casino has not yet developed a dedicated native mobile app. However, the website has been optimized with HTML5 technology, which makes it easily accessible by mobile devices that are compatible with the Blackberry, iOS, and Android operating systems. The only other thing needed for mobile access is a standard web browser.

Just type on "Mega Moolah" or "WowPot" to the search box and results will start pouring in. Our favorite at the moment is Mega Moolah The Witch's Moon.
