How Mobile Casino Sites Are Rated
Device Compatability
The most significant area of contention has to be when it comes to device compatibility. In short, in today’s age, it is more or less essential that any mobile slot site works on every device. Gambling providers do this in various ways, either in the form of a mobile slots app, which will be separated into one for iOS and one for Android. Secondly, they will offer a completely responsive experience from your smartphone browser. Both methods have their benefits and drawbacks and some companies have a complete suite of apps but also allow browser-based gameplay as well. Lastly, they can’t negate desktop play, if everything looks fantastic from your mobile phone but then on desktop, everything is not how it should be, this is a serious drawback.
Choice of Slot Games
The next area of important consideration has to be with regards to game selection. Does the online slot site feature a wide portfolio of gaming titles? Are they all available to both app and browser-based players? Do they feature the latest HTML5 technology? All of these questions are important and bingo sites without the essential prerequisites are rated lower in our rankings.
Likewise, it’s not just slot games, we try to build a holistic picture and take into account the presence of bingo games and casino table games also. After all, most of the visitors to our website would like to play at a brand that features it all.
Speed and Software
Another important area we look into is with regards to the software platform the website is based on. Do they work with the leading iGaming software providers such as NetEnt, IGT, Barcrest and Yggdrasil? Aside from slots games, we also look at how fast the games load, whether the software is clunky and if there are any bugs that slow things down.
Bonuses and Promotions
It’s not all about software and technology related to phones! We know what customers care about and most of all, its about getting a nice and juicy welcome bonus. We provide higher ratings and superior rankings to brands that offer a generous bonus. We take into account what is offered in terms of the bonus amount, the number of free spins and the wagering requirements.
Wagering and Withdrawals
Likewise, it’s critical to easily deposit and withdraw from a website. We only work with brands that offer swift deposits using debit cards, along with many of them featuring e-wallet compatibility such as PayPal. We check if a site makes it easy or difficult to get your money on and off the website and what kind of verification is needed to do so.
UKGC Licensing
Last but not least, we do not recommend any mobile slot sites unless they are fully licensed by the UK Gambling Commission (UKGC). This is because the UKGC has stringent standards when it comes to offering gambling services and providing a safe gaming experience. If a website doesn’t bare the seal of approval from the regulator, our advice is to move on and find one that does.
