Captain Marlin Casino Review

Complete with its quirky cartoon mascot, Captain Marlin Casino has a firm emphasis on fun, with competitive “Battle” events pitting player against player as they compete for cash and top tech prizes. A rewarding three-stage welcome package will also help new customers get off to a winning start at the site, with almost €3,000 in bonuses available to help them enjoy the thousands of games on offer.

Though somewhat of a newcomer in the non Gamstop casino scene, the team behind Captain Marlin Casino have over a decade’s worth of experience in the industry and know exactly what it takes to run a successful gaming operation. The site boasts a license from the reputable Curacao eGaming board, which ensures provisions such as secure 128-bit SSL encryption and the fairness of all available titles.

As such, Captain Marlin Casino is an extremely safe and reputable place to play, where players can enjoy top games from big-name providers without having to worry about the safety of their personal or financial details. As a casino site not on Gamstop, Captain Marlin also offers an unrestricted gaming experience, making it a top choice for UK players who’ve previously self-excluded under the scheme.

Welcome Bonus

Captain Marlin casino bonus

Captain Marlin Casino offers players the chance to claim a whopping 475% up to €3,000 in bonuses across their first three deposits. Somewhat unusually, the package starts with the biggest of the three bonuses, but the full offer is broken down as follows:

  • First Deposit Bonus: 200% up to €1,000 (minimum deposit €40)
  • Second Deposit Bonus: 150% up to €1,000 (minimum deposit €100)
  • Third Deposit Bonus: 125% up to €1,000 (minimum deposit €200)

Other Bonuses & Promotions

On top of that initial welcome package, Captain Marlin Casino also boasts a number of ongoing offers that provide further value to frequent players. These mainly consist of weekly “Battle” tournaments and lotteries, but reload bonuses are also available periodically. Some of the regular highlights include:

  • 200% Reload Bonus when you deposit €40 or more*
  • Weekly “battle” tournaments with €2,500 prize pools
  • Regular “Prize Box” lotteries offering cash and other rewards

*Although advertised as a “sports bonus”, this offer can be used on any slots or casino games.

With all that and more to choose from, there are plenty of great incentives for players at Captain Marlin Casino. The site also regularly features quick-fire deposit offers and no-deposit free gifts, so players should always keep an eye out for the latest available giveaways on the main promotion page.

Casino Games

One of the most standout things about Captain Marlin Casino is the vast number of games on offer. No matter where they access the site from, players will find an incredible range of over 3,750 titles available from leading providers such as NetEnt, Novomatic, Spinomenal and Quickspin. With almost 90 gaming brands to choose from, players can find their favourite title from the following categories:


With its heavy emphasis on competitive “Battle” tournaments, it’s perhaps not surprising that the bulk of Captain Marlin Casino’s game offering comes in the form of slots. With literally thousands of titles on offer, players will be able to choose from top games like Lord of the Ocean, Thunder of Olympus and Book of Sun or unusual slots from up-and-coming boutique studios like Booongo and 7mojos.

Table Games

While Captain Marlin Casino’s slot selection is truly vast, the site doesn’t skimp on table games either. With casino staples such as blackjack, roulette, baccarat and casino poker all available in versions to suit all budgets and playing styles, you won’t have to look far to find your favourite title. On top of that, the site also hosts a number of more exotic games like Pai Gow, Sic Bo and Three-Card Rummy.

Live Casino

Players looking to crank the excitement level up even further will be pleased to know that Captain Marlin Casino is also home to a live casino section that offers streamed versions of their favourite games 24/7. Popular options like blackjack, roulette and baccarat are available across multiple tables, but if they dig a little deeper, players will also find game shows like Spin 2 Wheels and Keno Deluxe.

Other Games

To round out what is a thoroughly comprehensive game offering, Captain Marlin Casino also offers a number of instant-win scratch cards and video poker titles. Located in the “Other Games” section of the site’s main lobby, players will also find a selection of bingo titles, dice options and fun mini-games that offer pick-up-and-play, arcade-style action with the added possibility of winning real cash prizes.

How to Sign Up at Captain Marlin Casino

Given its fun-first brand position and inviting design, it makes perfect sense that the sign up process at Captain Marlin Casino can be completed in just a few clicks. To get started, players simply need to press the “sign up” button at the top right of the homepage and the first of three pop-ups will launch.

Initially, players will only be asked to provide a valid email address and create a password for their new account. They will also have to check the box to confirm they’ve agree to the site’s terms and conditions. Once this step is complete, a new window will launch requesting a few personal details.

Here players will need to enter their name, date of birth, home address and contact telephone number before hitting the yellow button to confirm their details. This will take them to the third and final step of registration, which is optional and allows players to instantly deposit and claim their welcome offer.

As is usually the case with sign-up bonuses, players should note that once they activate the first part of their welcome offer, they will have seven days to complete all wagering on it and the two deposit bonuses that follow. These all come with 40x wagering, so it’s important to plan your time accordingly.

Deposit & Withdrawal Methods

Captain Marlin Casino offers quick and easy payments via three main options – Visa,  Mastercard and Bitcoin. The minimum deposit limit varies for each payment method and not all can be withdrawn to, so players are advised to familiarise themselves with the table below before choosing the best option.

Payment MethodMinimum DepositAvailable For Withdrawal?

As you can see, players wishing to make instant, charge-free deposits via a method that can later be withdrawn to are best off choosing Mastercard as their preferred payment option. Those who don’t wish to share their financial details with the site, meanwhile, can deposit anonymously via Bitcoin.

While the processing times for withdrawals vary depending on the method used, most cash out requests are returned to players’ chosen account in between 24 and 72 hours. Players should be aware, however, that the minimum withdrawal on the site is slightly higher at €150 for all options.

Support and Security

One of main conditions of obtaining a license from the reputable Curacao eGaming regulatory body is that you do your due diligence when it comes to site security and player protection. There are certainly no exceptions made at Captain Marlin Casino, where users will get to enjoy complete peace of mind.

For starters, the site is protected by secure 128-bit SSL encryption. This means that any personal or financial data submitted at Captain Marlin Casino will be protected from online threats such as cyber attacks or data breaches and that it will only ever be seen by the exact people that its intended for.

In addition to that safety protocol, players at Captain Marlin Casino will also be pleased to note that all of the games on the site have been independently verified as fair and random by a third party auditor. This means the house holds no additional advantage and that all RTP statistics are accurate.

Should players need to contact Captain Marlin Casino, they can do so via email, UK telephone number or live chat. If their query is related to problem gambling, there are also a number of useful resources located in the responsible gaming section of the site, including links to GamCare, Gamblers Anonymous and BeGambleAware. Voluntary self-exclusion at the site is also available on request.


One of the bright young things among the current crop of non Gamstop casinos, Captain Marlin is rapidly establishing itself as the venue of choice for UK-based players who have previously self-excluded under the scheme. The site offers an unprecedented selection of slots, table games and live casino options that can be enjoyed with the help of an incredibly generous welcome package, while the regular “Battle” and “Prize Box” events are a fun and fast-paced way to win further rewards. If we had one minor issue with Captain Marlin Casino it would be that the range of payment options could be extended in future so that players using eWallets and pre-paid cards were also catered for.
