Osiris Casino

Last Updated: March 15, 2023

Established in 2015, Osiris Casino is among the newer gambling sites in the UK market. Licensed in Curaçao, it comes with an impressive array of features, including a variety of bonus offerings, and a wide range of casino games. The main inspiration behind the casino’s design is the Egyptian god, Osiris. Hence, the theme is an ancient Egyptian one, with the website featuring various artworks against a dark brown background. Welcome to this in-depth review, as we look closely at Osiris Casino.

With its ancient Egyptian graphics, rendered in rich browns and desert tones, Osiris certainly stands out from competitors, along with its offers for new players. You will find a lavish welcome bonus (which will be fully explained below) offering free spins alongside weekday and weekend bonuses. Besides that, the operator keeps adding new games to its collection, appealing to both new and repeat customers. What’s more, it is quite serious about its customer service, as well as privacy and security for its users.

Osiris Casino Welcome Bonus

The welcome bonus at Osiris Casino is a jaw-dropping one. You will receive bonus money up to £1,800 in matched deposits. The casino bonus itself will be made available in three stages, corresponding to your first three deposits. On your first, you will get a 300% matched bonus of up to £900. The subsequent deposits will net you 350% and 400% in matched bonuses, up to a maximum of £600 and £300, respectively. Moreover, these bonuses cover slots from several leading game providers.

Osiris Casino Free Spins

Besides extensive matched deposits, the welcome bonus also includes generous numbers of free spins. The first deposit will earn you 20 free spins that you can use on the Lost Mystery Chest slot. Your next deposit earns you an additional 30 free spins for Book of Helios. Lastly, you’ll get 40 free spins on the third deposit, usable on Take The Kingdom slot. The best part is that you’re eligible for these free spins on deposits made through any of the payment methods.

Bonus Terms and Conditions

Unless otherwise mentioned, the minimum deposit that you need to make in order to qualify for a bonus is £20. You must also use the bonus within 15 days of obtaining it, otherwise the casino reserves the right to remove it from your account. In addition, any bonus money you earn will be subject to a standard wagering requirement of 33x. Last but not least, you cannot withdraw more than 10x the value of any cash or cash back bonus you receive.

Osiris Casino Games and game providers

The casino features an extensive catalogue of games, covering more than 300 slot titles. These games come from a wide variety of game developers, with titles from both big names and smaller companies. As a user, you will readily find games from BetSoft, Cool Games, Elk Studios, Felix Gaming, NetEnt, Thunderspin, and Zeusplay, among many others. Besides, you can also filter these games by providers and features, including bonus bet options. Regarding the user interface, it’s quite intuitive, featuring user-friendly navigation buttons.

Apart from slot titles, Osiris Casino also brings an exciting collection of table games and live dealer games to the avid gambler. In fact, you can find numerous variations of blackjack, roulette, and poker games. The games are neatly organised into a number of suitable windows, including separate tabs for bonus games, table games, live titles and all games. Although there are no exclusive games currently, the site also provides scratch cards, as well as instant-play titles from developers such as Thunderkick.

Customer service

Osiris online casino does not fall short of expectation in the customer support department either. Quick and professional customer service is available 20 hours daily between 4am and 12pm in GMT or London Time. Furthermore, you can contact support via email or live chat. The support staff possesses detailed knowledge of the casino’s workings. However, one disappointment is the lack of a phone option. While there is no FAQ section, you will find an ‘About us’ page alongside a detailed ‘terms & conditions’ page.

Payment methods

Osiris Casino Deposits

The casino offers an array of deposit methods to choose from. You can easily pay using Visa, Mastercard, Neteller, Skrill, EcoPayz, Paysafecard, and others. Mostly, the processing time is instant and there are no fees for the transactions either. However, note that the processing time may sometimes vary depending on your choice of deposit method. In addition, while the online casino does not charge any deposit fees itself, the payment gateway might. Thus, it is always advisable to check with your payment provider.

Osiris Casino Withdrawals

You can request a withdrawal using credit or debit cards, e-wallets such as Neteller and Skrill, and bank transfers. The processing time for e-wallets is under 24 hours. However, bank transfers may take five days to arrive in your account. Moreover, card-based withdrawals may take even longer, with up to 10 days of processing time. When it comes to withdrawal fees, Osiris Casino does not levy any charges, though some banking providers do. What’s more, you may incur small charges for currency conversion.


Osiris Casino has done a lot of legwork when it comes to providing a safe and trusted gambling space for its players. There is a 128-bit SSL encryption in place, along with firewall protection for the servers. This means that your user data and banking information are safe from internet fraud and theft. The casino further promotes responsible gaming, with strict provisions against underage gambling, for instance. As for legitimacy, the online casino holds an Antillephone N.V. licence from the jurisdiction of Curacao.

Osiris Casino Verdict

Overall, Osiris makes for a comfortable and pleasant gaming experience in a secure and regulated setting. You can try a wide range of titles and enjoy myriad of promotions. Besides the curated games and copious bonuses, you can use your preferred payment method and reach out to a well-trained support service. So, sign up for an account and make your first deposit. And you will be ready to enjoy a welcome bonus, free spins, scratch cards, video slots, and more in no time.
