Online Gambling Sites To Try

We’ve compared a multitude of sites to see which ones offer the best features and opportunities to make a profit. The casinos listed below are 100% safe and secure, tested, and reviewed by our team.

  • MrSmith Casino

If you’re looking to play at an online casino that knows what it is doing, MrSmith is a great option.

A little over two years ago, the UK company Harry Casino was bought by betting giant Bettson and rebranded to MrSmith Casino.

Under the wings of the giant bookmaker, MrSmith has made great strides, establishing themselves as reliable Casino with a vast selection of games, all from the gambling world’s top software providers.


The site features an extensive variety of branded slots, high-definition video slots, and games inspired by TV shows, famous stories, and myths.

These include Jurassic Park, Cleopatra, Spartacus, Viking Runecraft, Game of Thrones, and much more.

Taking everything to the next step, Mr Smith has opened its doors to the rest of the continent by opting for a Net Entertainment software platform.


Punters who sign up with MrSmith Casino get their first deposit doubled. Punters can deposit up to £200 to play with £400.

What we don’t like about this promotion is the hoops one has to go through to actually get the money – The Bonus must be wagered a minimum of 35 times within 14 days of the Bonus being claimed.

On a positive note, on top of the return on the first deposit, new players also receive 20 free spins on NetEnt’s Blood Suckers II, and that is definitely a good incentive to use this bonus.


Mr Smith Casino’s live chat representatives are available 24/7 to answer any questions.

Players can contact an associate by clicking the menu icon on the top-left and hit “Su­ppo­rt” in the drop-down.

They can also be contacted via email, social media platforms, and you can also access their telephone number in the Contact Us section.The number is Maltese, but this is okay – English is spoken fluently in Malta.


Mr Smith Casino passed this criterion with flying colours.

Their range of payment options is arguably one of the largest amongst casinos. Furthermore, If you use NETeller or MoneyBookers, you are guaranteed same day cash outs, which is the industry standard.

Bonuses And Promotions

We personally compare online casino bonus offerings; this is where gambling knowledge is key.

Some bonuses may look great from a distance, but a good look at the terms and conditions tends to filter out casinos who are actually offering a profitable promotion from those who just want to lure you in.

The Games

Finally, we look at the fun part – the games.

The software that online casino sites use is an important factor in online gambling, influencing the type of games on offer, their accessibility, graphics, etc.
