Since its establishment back in 2020, Duelbits has become a well-known crypto casino and sportsbook. Along with thousands of games in its portfolio, the casino also offers a range of tournaments and sports-specific bonuses. But does all this make up for the fact that there's no sign-up bonus up for grabs, or the high minimum withdrawal amounts in BTC, ETH, and USDT? Find out in my in-depth Duelbits Casino review.

Sports bonus + tournaments for the win


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 no, there is currently no Duelbits welcome bonus up for grabs. At least, not for casino. Sometimes, the casino has a sign-up bonus in the form of free spins, but we’ll update you if this deal makes a return any time soon.

Sports Welcome Bonus

Are you a sports betting aficionado? If so, you’ll be as happy as we were to discover Duelbits’ generous sports welcome bonus. How does it work?

  • Deposit up to $100 and a 100% bonus in the form of free bets
    Note that you’ll need to meet the 5x wagering requirements to receive your original deposit back as a free bet. You can find the bonus in the ‘My Rewards’ section on the left-hand menu.

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 I’m 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 well-populated 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’ll find 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

I believe that no crypto casino is complete without a Bitcoin 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, so you’ll progressively ascend several ranks as you play:

  • 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!) Some encouragement, though: you can look forward to numerous rewards every time you level up, including an Instant, Daily, Weekly, and Monthly Rakeback.

Duelbits Bonuses vs Competitors

So, how does Duelbits stack up against competitors in the bonus department?

Not too well, I’m afraid. Let’s look at some of the deals other platforms have to offer:

  • BC.Game: It’s hard to beat BC.Game’s combined 1080% deposit match bonus up to $220,000 (or crypto equivalent) spread across your first four deposits. The platform also has a Lucky Wheel where you can snag significant crypto prizes. Add in a great VIP program, regular promotions and boosted odds for a bigger picture.
  • Cloudbet: Cloudbet actuall does beat BC.Game in the welcome bonus department. The casino offers a 100% deposit match up to 5 BTC. That’s really massive, and I’ve yet to speak to anyone who has cashed in the whole 5 BTC, but still. The VIP program is also solid.
  • JackBit: Home to the new JackBit no deposit free spins bonus! Better yet, the free spins are wager-free. However, the most you can win is 100 USD, so it’s on the smaller side. JackBit also has a sports welcome bonus for betting fans. Another excellent VIP program.

So now you’ve had a glimpse of what’s out there, and it’s quite clear to see that even though Duelbits’ bonuses can hold their own, they do pale in comparison to those offered by similar brands.

Look & Feel

Clean, intuitive + vibrant on-site chat


Regarding looks, I’ve got to take my hat 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. I was able to navigate anywhere on the site with one or two clicks – a huge green flag in my book.

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, I 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, I’m happy to report that Duelbits is 100% mobile-friendly.

It’s clear that the design team made 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

I was also pleased 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


I quickly discovered that 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 8 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. I tested the entire selection, and I managed to settle on a favorite:

  • Crash

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

The design is top-tier, the graphics are smooth, and it runs perfectly on mobile. I’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.

Crash aside, I was excited to see that Duelbits is currently working on more original games to add to the selection. I’m not sure they’ll get up to BC.Game’s level any time soon (40+ in-house games) but growth of any kind is always a good sign.


Duelbits boasts a solid 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? Duelbits’ selection of just over 150 live casino titles should have you covered. 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 I expect Duelbits to broaden its selection in the coming months.

I tried a few different live dealer titles, and I have to say that my 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 I 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.

I also like that Duelbits shows the RTP of each game when you hover over the tile (on desktop). It makes it much easier to choose your ideal title. A+ for transparency here, Duelbits!


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

I briefly addressed some of Duelbits’ sports bonuses, but I haven’t really discussed their value. As a general comment, I was pretty 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. If you’ve read any of my other reviews, you’ll know that I’m a big proponent of enabling 2FA on all your casino accounts for added security.

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

I spent a good few hours checking out user reviews on sites like Trustpilot, and it’s clear to see that players are mostly happy. In the case of complaints, Duelbits has an excellent response rate and takes the time to address each comment in great depth. By the way, Duelbits has a steady 4.1-star rating on Trustpilot.

Does Duelbits Request KYC?

In other words, you can’t play anonymously at this casino. If that’s a deal breaker for you, then I suggest checking out our list of the top anonymous crypto casinos out there.

The KYC process at Duelbits is pretty standard (you can check out our guide to KYC checks if you’re unsure, though).

You’ll need to supply a picture of your ID and some other basic information. So be sure to provide accurate details when you’re signing up, or this will bite you in the butt later down the line if your information doesn’t line up.

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.

Payment Options

Both cryptos and fiat accepted


Duelbits supports a decent number of cryptos, and, unlike many competitors, it also accepts fiat payments!

Here’s a list of the 10 cryptos supported:

  • Bitcoin
  • Ethereum
  • Litecoin
  • Dogecoin
  • Binance Coin
  • Solana
  • Tether
  • Shiba Inu
  • Ape Coin
  • Tron

As for fiat, you can use any of the following methods to purchase ‘Gift Cards’ on the site:

  • Visa
  • Mastercard
  • Skrill
  • Paysafecard
  • WebMoney

Duelbits also has an on-site exchange, where you can buy crypto directly using fiat. However, this only works if you’re buying ETH with USD.

Duelbits Deposits

Depositing at Duelbits is a simple process, and I managed to get it done in under 5 minutes using one of my favorite Bitcoin wallets for online gambling – Trust Wallet. I’ll give you a quick run-down of the process:

  • Once you’ve successfully registered, head over the the ‘Cashier’ section in the header.
  • Select your preferred coin.
  • Copy the custom wallet address.
  • Paste the address in your wallet.
  • Input the amount of crypto you’d like to deposit.
  • Hit send!
  • Wait for your funds to reflect.

It took a few minutes for our funds to reflect, but other users have reported instant deposits.

Note that Duelbits has minimum deposit limits, but only on two coins:

  • Binance Coin: $10
  • Tether: $50

I have to say that the min. deposit limit for Tether is really high! I’ve seen a few players complaining about the USDT limits online, and Duelbits has acknowledged these complaints. No changes yet… however.

Duelbits Withdrawals

Once you’ve generated some funds in your bankroll, you’ll probably start thinking about cashing out. Aside from having to submit KYC documentation, it’s a relatively easy process – no different from other successful crypto casinos.

And, like many crypto casinos, Duelbits has minimum withdrawal limits and fees which vary from coin to coin:

CoinMin WithdrawalEstimated Fee
Tether (ERC-20)$50$9.90
Tether (BEP-20)$50$0.12
Binance Coin$25$0.02
Ape Coin$50$7.12

Fortunately, there are no maximum withdrawal limits at Duelbits. Even better, I tested the cashout process and I’m pleased to confirm that the casino facilitates instant withdrawals.

I’m sad to close off this section on a negative note, but Duelbits has some pretty unfavorable minimum withdrawal limits for USDT, Bitcoin, and Ethereum. Let’s compare them with some other top platforms:

Min. Withdrawal (in USD equivalent)StakeBC.Game
Tether$1$11.58 (TRC20)
Withdrawal limits at the time of writing (February 2024) and note that these also vary based on your chosen network.

I think we can all agree that Stake’s limits are hard to beat. But BC.Game still leaves Duelbits in the dust. Something to consider if you prefer to play with – and withdraw – smaller amounts.

Customer Support

On-the-ball team + extra resources


Help comes to those who need it at Duelbits via:

  • Email
  • Live chat
  • Discord

I tested the live chat a few times during my Duelbits test, and I couldn’t have been happier with the results. In each instance, I got answers in under 5 minutes. The customer agents were always helpful and professional, too.

Duelbits Live Chat

Duelbits is also active on Instagram and Twitter, a big plus in my book. The casino’s extensive blog also offers interesting insights and tips – especially when it comes to optimizing bonuses and new features.

I’ve already mentioned the platform’s great response rate on external review sites like Trustpilot.
