Finding the Best Online Slot Sites

The best slots casino sites usually come with a few different attributes that ensure you always have a great time playing at them. So, to find them, you need to be on the lookout for certain features

And, of course, what works for one player may not necessarily be the right thing for another. We’ve got a few pointers that you can follow for guidance towards finding the best new slot sites, though. This way, you always know that you’ll be playing new games on one of the most powerful platforms.

How to find the best slot casino site

Number of Slot Providers

It may seem quite obvious to say, but a casino that features a more significant number of game providers contributing their releases to its lobby is going to stand out more. Why? Because, in theory, it will have more games for you to play. Diversity is always a critical factor in an online slot site being known as one of the best. A stronger piece of games will be present with a robust selection of software developers providing their games to a site.

There are so many providers operating and creating online slots today that online casinos have so much to choose from in terms of their lobbies host. And many of them can be considered the world’s top developers, too. This includes companies like the highly popular Netent, the long-running Microgaming, the innovative Thunderkick, the exciting Yggdrasil, the amazing Playtech, the 3D stylings of Betsoft, the fantastic IGT and various others.

The more these companies serve their portfolio of games up to an online casino, the better it is for you, the player. And, of course, consequently, the better it is for the casino, too. And that’s why it’s always better to locate an online slot site with multiple game providers serving them. It’s beneficial to everyone involved, and you get to enjoy some of the best entertainment in various forms.

Here are some of the providers we suggest looking for were hunting a slot casino.

NetEnt Slots and Casinos


NetEnt is an award-winning provider in online casinos, producing many firm favourites of gamblers.

Microgaming Casinos and Slots


Microgaming is the world’s largest offering over 850 casino games and two new titles every month.

Pragmatic Play Casinos and Slots

Pragmatic Play

Pragmatic Play, a software developer that puts simplicity first, has become a casino favourite.

Play'n GO Casinos and Slots

Play n GO

Play’n GO have created a large range of high-quality games available in 30 different languages.

Several Slots Categories

When visiting some online casinos, you will simply see a category labelled as ‘Slots’, and nothing more in relation to such. Even in the social casinos, such as Chumba casino review, you won't find much more than 'Slots', but in reality, there are several slots categories. If you're feeling like trying this social casinos experience, you could redeem the Luckyland Slots no deposit bonus 2024 to try their games.

This sees all of the available slots piled into one area, giving you masses to sift through in order to locate the ones you like the look of for playing. Yet there are those slot sites that incorporate multiple categories for you to check out, incorporating different types of slot games within.

Some of the categories on hand at many of the top slots sites include:

Slot Bonuses & Free Spins

When registering for an account at an online slots site, it is always ideal to benefit from a wonderful bonus spins reward after depositing. Free spins cater specifically to slot machines, and if you can play one or more slot games without needing to utilise your max deposited money on them, what could be better?

Some slot sites offer their new players a set of bonus spins alongside a welcome bonus, giving a double reason to sign up for an account. Those bonus spins can sometimes be used on one specified slot machine or a few selected ones. 

Alternatively, you may come to join a casino that provides a set of no deposit bonus spins instead. These don't even require you to have deposited receiving the associated reward. You register for an account and verify your registration before the batch of bonus spins is credited to your account instantly.

Free spins bonuses, in whatever fashion they are provided, will always be welcome by slot gamers. They offer an insight into one or more slot machines for players to benefit from. And then, once you have checked into these releases, you may wish to continue spinning the reels with the money you have deposited.

Some of the most common slot games casinos create promos for are:

  • Book of Dead

  • Starburst

  • Age of the Gods

  • Gonzo's Quest

  • Mega Moolah

  • Joker Poker

These bonuses have a set of T&Cs players must follow to convert and cash out the bonus to a debit card or e-wallet. Some of these full terms and conditions are the day expiry, minimum deposit, max win, max bet, spin value, and a set of rules about the bonus wins. 

We recommend playing the bonus spins on slots with high RTP to convert it faster.

Solid Gambling Licence

We will always recommend the online casinos that possess an official licence to you to join. However, these are not just any gambling licences. They are from reputable jurisdictions, ensuring that all operations are done safely and securely. A gambling licence from a respected location also means that you, the player, are protected against any wrongdoing by the associated casino.

Some of the best locations for slot sites to possess official licences from include:

  • Malta

  • United Kingdom

  • Alderney

  • Gibraltar

  • Isle of Man

  • Kahnawake

It would be prominent to note the jurisdiction of Curacao here as well, although, in the past, this has not been considered a solid gambling licence location. The steps that a platform has to take to secure such a licence are notoriously simple. It has been discovered that some slot sites haven't had to continue payments to maintain the licences and have not been kept in line with supposed regulations. 

Little repercussion has come from this. And even though many casinos holding a licence from Curacao are operating in a safe, fair and legal way, there are those which do not.
