Duelbits Bonuses

Duelbits has a decent range of promotions on offer, for new and existing players alike. We’re sure you’re dying to hear about them all, so let’s dive right in:

Is There a Duelbits Welcome Bonus?

The question on everyone’s lips! The answer is yes, but it’s less substantial than some competitors’ offerings. Duelbits’ welcome offer comprises a 50% Cashback upon registration. How do you go about claiming this deal? It’s pretty simple:

  • Register an account
  • Make a deposit and play
  • Receive your 50% Cashback

How does Duelbits’ welcome bonus stack up to big names like Stake and BC.Game? Not well, we’re afraid. The former sites have more comprehensive deals on offer. So, if you’re big on sign-up bonuses, you may want to check these casinos out instead.

In the future, we’d like to see a more substantial welcome bonus from Duelbits. But enough about sign-up deals for now! Let’s move on to some of Duelbits’ other promotions:


Duelbits is big on tournaments. Currently, they have 7 ongoing tournaments – and we’re going to address three player favorites:

  • Drops & Wins Slots – $2,000,000: You can win your share of 2 million USD each month. Between April 2023 and March 2024, Duelbits will award a grand total of 24 million dollars to its players. This promotion will be split up into 48 Weekly Tournaments and 366 Daily Prize Drops on select Pragmatic Play slots.
  • Aphrodite’s Golden Touch – $10,000: Play any selected Spinomenal slots (minimum of $0.20 per spin) and collect as many points as you can. The top 120 players will share in the prize pool, with the top player earning $1,400 (or crypto equivalent) and the 120th player receiving $20.
  • Drops & Wins Live – $360,000: Live casino fans, listen up! You can win your share of $360,000 each month by playing your favorite live casino titles. Any real money spin in the participating games may trigger a random cash prize. On the downside, the maximum amount per win is capped at $1,000.

Sports Bonuses

Duelbits Sports Bonuses

Duelbits has a thriving crypto sportsbook, and they’re not shy about doling out regular sports-specific bonuses. We won’t go into the nitty-gritty here, but here’s a summary of some of the bonuses you can look forward to if you start betting at Duelbits:

  • NHL Overtime Insurance
  • Aston Villa – Giveaway
  • 10% Cashback on Tennis Bets
  • Better Odds on European Major Leagues
  • MMA First-Round Insurance

Duelbits VIP

Ace VIP Club

No crypto casino is complete without a VIP program. Duelbits’ program comes in the form of Ace’s VIP Lounge.

This is a non-exclusive program, meaning you automatically join up as soon as you register at Duelbits. It’s also tiered, and you’ll progressively ascend several ranks:

  • Joker
  • Club
  • Heart
  • Diamond
  • Spade
  • Flush
  • Jack
  • Queen
  • King
  • Ace
  • Duelbits

Note that from Jack onwards, each category comprises 5 mini-categories. In other words, it’s going to take you some time – and a lot of wagering – to reach the final tier.

For example, you’ll need to wager $1,000 before you unlock Joker. You’ll need to wager a whopping $1,000,000,000 before reaching Duelbits (sheesh!) Rest assured though, that you can look forward to numerous rewards every time you level up, including an Instant, Daily, Weekly, and Monthly Rakeback.

Look & Feel

Clean, intuitive + vibrant on-site chat


Regarding looks, we’ve got to take our hats off to Duelbits. The casino boasts a clean, dark aesthetic with pops of color reminiscent of a classic arcade.

Aside from this attractive interface, Duelbits boasts an intuitive side menu, populated with neatly-organized categories and corresponding icons. We were able to navigate anywhere on the site with one or two clicks – a huge green flag in our books.

It’s incredibly easy to switch from the casino to the sportsbook, and you’ll find a bunch of helpful links in the footer, too.

Duelbits also caters to players from around the world, and by that, we mean that the site is available in 7 different languages:

  • English
  • Portuguese
  • Italian
  • Spanish
  • Dutch
  • Cantonese
  • Mandarin

Duelbits on Mobile

After extensive testing on multiple mobile devices, we’re happy to report that Duelbits is 100% mobile-friendly.

It’s clear to see that the design team went to great efforts to make the casino accessible for players who like to play on the go. Menus are adjusted accordingly to suit smaller screens and an intuitive carousel showcases the top offers and news.

Duelbits Mobile

We were also happy to see that the casino has an active on-site chat where players share their wins (and mourn their losses) – albeit often through Pepe gifs and emotes. It’s always good to see evidence that players are having fun.

Note that if you want to join in on the discussion, you’ll need to deposit at least $100 at the casino.

Game Selection

Original games + slots galore


Duelbits takes its game offering seriously and has managed to pull together an extensive library stocked with thousands of games. From slots to provably fair games – and pretty much everything in between – not to mention the site’s stellar sportsbook.

Let’s unpack some of Duelbits’ best offerings:

Duelbits Originals

Duelbits Originals

Duelbits has 6 original and 100% provably fair games that you can’t play anywhere else. Provably fair? This means that you can personally verify the fairness of the results. We tested the entire selection, and we managed to settle on a favorite:

  • Crash

It’s no secret that we’re huge fans of Crash, just check out our list of the top Bitcoin Crash casinos if you don’t believe us. Despite the many versions of Crash out there to date, we feel that Duelbits’ adaptation is a solid one.

The design is top-tier, the graphics are smooth, and it runs perfectly on mobile. We’d even go so far as to say that it rivals even Stake Casino’s celebrated Crash variation.

Duelbits Bitcoin Crash

Add in the fact that fairness is guaranteed, and you’ve got a recipe for success.


Duelbits boasts an incredible collection of over 3,000 slots. That’s enough to keep even the biggest slots aficionado busy… for a good long while, at least.

You’ll find titles produced by some of the best software providers in the biz, including big brands like:

  • Pragmatic Play
  • Hacksaw
  • Spinomenal
  • BGaming
  • Evoplay
  • NetEnt

When it comes to slot variations, Duelbits Casino covers the progressive, classic, and video slots genres – the whole shebang, really. It’s unlikely that you won’t find your favorite at this casino. If you can’t, don’t worry. Simply make use of the nifty search bar and type in your desired game.

Live Casino

On the hunt for something a bit more personal? Look no further than Duelbits’ selection of close to 150 live casino titles. Here, you’ll have no trouble finding various adaptations of:

  • Roulette
  • Blackjack
  • Poker
  • Baccarat
  • Sic bo
  • Game shows

Wondering about the software providers responsible for this diverse selection? You have Evolution and Pragmatic Play Live to thank. Truth be told, it would be nice to see a longer list of providers, but we expect Duelbits to broaden its selection in the coming months.

We tried a few different live dealer titles, and we have to say that our favorite – by far – was Speed Baccarat by Pragmatic Play Live.

Speed Baccarat
Try out this fast-paced baccarat variation with an RTP of 98.94%.

Why do we like it so much?

  • It’s simple
  • The hosts are professional
  • It has a decent RTP

But this is just one of the many Bitcoin live games on offer at DuelbitsCasino, and there’s plenty more for you to explore.


Fancy a bit of sports betting with BTC? Duelbits has a pretty decent sportsbook, with over 28 different sports to bet on.

We’ve briefly looked at some of Duelbits’ sports bonuses, but we haven’t really discussed their value. We were actually pretty darn impressed with the sports bonuses on offer at this bookie.

Not only do they offer longer-term promotions, like the MLB Multi Insurance bonus, but they also have a slew of newer bonuses relevant to upcoming games.

Duelbits Sportsbook

So how does Duelbits’ sports book stack up to competitors? So so. It only has 28 categories, while bigger players like Rocketpot and Cloudbet have close to 40.

But, depending on how you view rewards, one could argue that Duelbits Casino makes up for its smaller selection with multiple sport-specific bonuses.

Licensing & Safety

Solid Curaçao license + betting partnerships


Is Duelbits Legit?

Yes, Duelbits is a legit and safe crypto casino. It holds a solid Curaçao gambling license, under license number #365/JAZ. The fact that Duelbits holds this license ensures that the casino upholds the latest security features to protect your data.

As an extra measure, Duelbits Casino also facilitates 2FA.

Further, the casino is an AFA regional sponsor and an official AVFC European betting partner. Both of these facts stand testament to the casino’s good standing in the community.

Does Duelbits Request KYC?

Yup, and if you’re looking for a more privacy-forward site, you may want to check out our list of the best anonymous Bitcoin casinos. According to the casino’s privacy policy:

The formal identification of Customers on entry into commercial relations is a vital element, both for the regulations relating to money laundering and for the KYC policy, namely the verification of ID Card and proof of address.

While Duelbits doesn’t request KYC upon sign-up, you’ll need to provide the above documentation before being able to withdraw your funds.

Responsible Gambling

Here at Casinos Blockchain, we take responsible gambling seriously. For that reason, we like to see casinos putting in a good deal of effort to promote the practice.

So how does Duelbits score on this front? Pretty well.

The casino has a comprehensive responsible gambling section, which includes links to helpful resources, definitions, tips, and what kind of behavioral patterns to avoid while playing.

If you find that you’re struggling, Duelbits facilitates self-exclusion, and you can request this via email. You can put your account on freeze for 1 week, 1 month, 6 months, or permanently.
