Today’s online gambling market is saturated with hundreds of casinos, making it difficult for players to decide which site is best for them. That’s why we set out to offer online casino players honest and unbiased reviews of the best slots casinos out there, so you can easily determine which operators cater to your tastes and are worth your patronage.

Large Game Selection

Players at online casinos should be given a great selection of games to choose from, and our favourites are those that have hundreds of games on offer. We like to see online casinos with a wide variety of jackpots, branded games, themed slots and unique formats.

If we were to pick our favourite casino based on game selection, we would certainly go with Slots Million. Currently, the online casino offers up over 1500 online slots for players to choose from, including games from top-performing developers like Microgaming, Net Entertainment, iSoftBet and Pragmatic Play.

Mobile Optimisation

With the majority of the population preferring the access the Internet using their smartphone or tablet, it is crucial for online casinos to ensure that players can play their favourite casino games on the go. Ideally, casinos should have browser-based game selections, which means that players do not have to download any additional software to their mobile devices. It also ensures that the games can run on various platforms like iOS, Android and Windows.

Our picks for best mobile casinos are Viks and BGO. All three of the online casino provide players with instant access to a huge range of online casino games that can be access from web browsers – with user friendly interfaces that cater to all types of players.

Impressive Customer Support

What really sets online casinos apart from one another is how they take care of their players. So, we value gaming sites that prioritise their customer service facilities. It is important for a site to provide live chat at all hours of the day and night to help players deal with any issues that they may encounter.

If we had to choose one online casino to play at based on its customer service, it would be Trada. Over the years, Trada Casino has been recognised for its commitment to providing great customer support and has even won awards for it. Trada also provides some of the fastest withdrawal times in the online casino market, with payouts processed in under 6 hours.

Generous Bonuses And Promotions

The best online slots casinos are those that reward their customers for their patronage. So, we’re always excited to see when gaming sites provide plenty of great bonuses for players to choose from. In addition to generous welcome bonuses, slots casino should offer up a wide range of online promotions.

G’Day Casino is one of the best slots casinos in that capacity. Every day of the week, the operator provides players with a different promotion that they can take advantage of. What really makes G’Day’s promotions special is that players are offered up a welcome bonus that has no limit to how much bonus cash they can claim!
