475% up to €3,000

Don’t be fooled by its goofy-looking mascot; Captain Marlin Casino is the real deal. This fun, community-focused non-Gamstop casino offers plenty of excitement to players in the form of “battle” tournaments – where the top-ranked players all win cash prizes – while daily “prize box” lotteries can give away everything from gadgets to bonuses. How many will you be able to reel in?

Captain Marlin is leading the charge of the next generation of non-Gamstop casinos. Every aspect of this casino is polished and professional, and if it’s not one of the industry’s biggest names in a few years we’ll be shocked. Huge bonuses, great games, lovely people, and an all-round secure platform.


Welcome to our Captain Marlin Casino review! After pouring hours into testing the platform and pestering the support team with endless questions, we’ve managed to put together the most comprehensive Captain Marlin review on the internet. From games to bonuses, from support to banking, we’ve covered every angle. 

And unlike many non-Gamstop casino reviews, we’ve actually verified our information with Captain Marlin staff so that you know exactly what you’re getting here. Let’s dive in.

Bonuses and Promotions

One of the defining strengths of all world-class online casinos is lucrative, straightforward bonuses. Well tell you what, Captain Marlin has put in some serious work creating several of the best promotional opportunities we’ve seen for a while. From the mind-bending 475% deposit matches to €40,000 lotteries, this place seriously has it all.

Casino Bonuses

Captain Marlin Casino has an impressive welcome package. Players can redeem up to €3,000 in bonus cash across 3 deposits, each with 3-figure deposit matches as follows: 

  • 1st deposit—200% up to €1,000
    • Minimum deposit €40
  • 2nd deposit—150% up to €1,000
    • Minimum deposit €100
  • 3rd deposit—125% up to €1,000
    • Minimum deposit €200

The general bonus terms are outlined below:

Promo Code

The terms and conditions for this welcome package are pretty standard. In order to take home any profits, players need to clear the 40x playthrough requirements. This can be done exclusively through video slots. Bets from table games or live dealer games will not be counted; nor will individual bets over €2. 

Across all 3 deposits, players will more or less double their money across these bonuses. While 40x playthrough isn’t negligible, some casinos put these as high as 70x or more! Players can also choose an alternative welcome bonus: 

  • 200% deposit match up to €1,000
  • Exclusively for sports betting
  • 35x wagering and €2 maximum wager size

Other Promotions

There are two further opportunities to bring in bonus cash: battles and prize boxes. 

  • Prize boxes—These are the most lucrative of all bonuses at the casino, with prize pools of up to €40,000. Incredibly, only five winners are picked for the biggest lotteries! The idea is that rather than hundreds of players winning small sums, a handful of players win life-changing money. Players must deposit between €50 and €300 to get involved. 
  • Battles—Captain Marlin runs twice-weekly slots tournaments (aka “battles”) with alternating prize pools of up to €2,500, plus additional rewards like smartphones and other tech products.

Unfortunately there isn’t a Captain Marlin Casino no deposit bonus. However, given the sheer quantity of awesome paid-for bonuses available, players can’t complain too much!

Casino Games and Game Providers

Unlike most online casinos which obtain licenses to a broad range of game developers, This Is Vegas Casino is powered entirely by Rival Gaming. This means the platform exclusively uses their famous i-slots, including: 

  • Dublin Your Dough
  • 5 Reel Circus
  • All Aboard
  • Party Parrot
  • Ocean Treasure
  • World of Oz
  • Panda Party
  • Viking Victory

There is a simplicity to gaming at This Is Vegas which we quite enjoyed: instead of getting bogged down in finding super-specific games from big-time developers, players can simply focus on picking a game and then working away at their gigantic bonus or using up their This Is Vegas free spins. (Because let’s be honest, that’s what players are really here for!)

In addition to video, classic and jackpot slot games there’s a generous range of table games. These include: 

  • Baccarat
  • Roulette
  • Blackjack
  • Pai Gow
  • Craps
  • Video Poker

We do have some bad news for hardcore table game fans though — there are no live dealers. If your main ambition is to play variations of table games (both RNG and live dealer) then it’s probably time to find another top casino.

Payment Methods

The team at Captain Marlin keeps everything to do with payments simple and straightforward.


The only available payment methods at Captain Marlin Casino are Visa, Mastercard, and Bitcoin. For players that don’t already have a Bitcoin wallet set up (or who have no real idea what Bitcoin is) the casino’s helpful staff will walk them through creating and funding a cryptocurrency wallet. 

Players can actually choose to set up recurring payments on their preferred schedule, working like a direct debit, for regular deposits. Note that the casino cannot process withdrawals to Mastercard (per their T&Cs) so we recommend depositing using Visa or Bitcoin to save hassle.


Unlike many new non-Gamstop casinos, Captain Marlin has withdrawal limits which are both generous and logically scaled: 

  • Per transaction—€500
  • Daily limit—€2,000
  • Weekly limit—€10,000
  • Monthly limit—€40,000

Players should note a couple of unusual rules regarding withdrawals: 

  • There must have been at least one real-money deposit made within the last 30 days of any withdrawal request; 
  • In order to withdraw profits from live dealer games or video poker, players must wager any previous deposits at least 5 times. 

The withdrawal processing time is up to 48 hours.

Help and Support

Even during peak hours, we received excellent care and attention from the live chat support team at Captain Marlin—shout out to Amelia and Alex! While the team is reachable by email or phone (details below) we recommend players use live chat as a first port of call. 


Like most non-Gamstop casinos, Captain Marlin has to work extra hard to guarantee its reputation as a safe and secure establishment for players—mostly due to the fact the casino doesn’t have a UKGC or MGA license. However, these licenses aren’t actually a requirement for running a casino. 

Captain Marlin implements its own strict rules regarding player safety & security, transactions, and data protection. The casino also takes an active interest in the welfare of players with its Responsible Gambling page sharing advice for self-diagnosing gambling addiction, self-exclusion and links to support sites.


Usually we’ll end a review reflecting on the primary strengths and weaknesses of a casino. However, the team is almost at a loss trying to find the weaknesses! Sure Captain Marlin could add a couple of payment methods and maybe drop the (industry average) wagering requirements, but that’s about it. 

The strengths are numerous: lucrative welcome package and ongoing promotions; incredibly deep field of top-quality slot and table games; the ability to withdraw up to €40,000 a month; responsive and genuinely personable customer support—the list goes on! 

If you’re in the market for your next non-Gamstop casino, this is the one.


  • What are the deposit limits at Captain Marlin?

    The casino doesn’t put any limits on the amount players can deposit—after all, they know players need to win at their games in order to take it out again! The withdrawal cap is €40,000 a month, but even if a player wins more than this they can simply cash out every month until it’s all in the bank.

  • How quickly are winnings paid out?

    It can take up to 48 hours for withdrawal processing to be completed. After this time, the money should be sent instantly using your chosen method. If your withdrawal has been processed but you haven’t received your money, please contact support.

  • Can UK players become members of Captain Marlin?

    Absolutely. Non-gamstop casinos are all about serving the UK market without the red tape and restrictions of those licensed under UKGC rules. Players signed up to Gamstop can still create an account with Captain Marlin and play as often as they like.

  • Who provides Captain Marlin’s gaming license?

    Like most non-Gamstop casinos, Captain Marlin is actually self-regulated. This means the casino follows its own laws on key subjects like data protection, transactions, fair game payouts and much more.

  • I’ve registered with Captain Marlin Casino—how do I activate my bonus?

    You should have been instructed by Captain Marlin to navigate straight to “my account” after depositing. There, you’ll find the option for activating your welcome bonus. Remember that you can only have one active bonus at a time, so work fast if you want all 3!

  • Is there a Captain Marlin no deposit bonus?

    Unfortunately all of the promotions at Captain Marlin do require a deposit. However, if you deposit more than €40 you can enroll for free in one of the regular lottery (or “prize box”) promotions running at the casino.

  • Does Captain Marlin casino have a mobile app?

    The customer support team confirmed that their developers are working on an app, but for the moment mobile players must visit the website manually using the browser on their device. This will work seamlessly for both smartphones and tablets, with all games and the full user experience optimized for mobile.
