About JohnSlots

Everything to know about JohnSlots, your friendly casino guide

We often talk about all the things we offer, like expert casino reviews and updates on casino bonuses and slots. But the real question is, who are we exactly and why do we do it? Read on to get to know a bit more about our site, our team and why we’re such fans of the online casino world.

What is JohnSlots?

To put it simply, JohnSlots is a slot comparison site, covering all the latest and biggest releases. Each review delves deep into the slot title so that you fully know what to expect before playing for yourself. As well as technical details, we analyse the most important aspects and offer a score out of five.

Our goal has always been to create a simple way for players to sift through information and find what they’re looking for. We’re here to bring you the best and latest slots news to make your casino journey smooth, and most importantly, fun. Our site also has a huge information that covers other casino game types – including bonuses – so there is something for all players.

What do we do exactly?

Anything and everything related to online casino and slots is what we do. From reviews, toplists, comparisons, guides, tips, industry news and more, you’ll find it all here, all in one place.

That includes more than 120 casino reviews (and counting) by expert players who really know their stuff, hundreds of slot reviews from the good to the bad, (we’re crazy about slots and we love discovering new ones), and various toplists to help you choose casinos or games.

What can I expect from JohnSlots?

Our expert team is on hand to give you the inside track on the slots industry. From playing guides to the newest releases, we have it all and if it is slots-related then you will find it here in an easy-to-understand way.

We ensure the safety and legality of all casinos and games mentioned on our site, so you can always rest assured that you’re playing with casinos you can 100% trust. Additionally, JohnSlots has unique bonuses that you won’t find anywhere else.

Which slot should I play next?

You have come to the right place! JohnSlots can help you narrow your search for a new favourite; in a few clicks you can be reading an in-depth review and then taking a few spins for real if you like what you find.

Whether you are aiming to try a fresh provider or are after a specific theme, our useful slot navigator tool can assist you based on your custom parameters.

How can I win when playing slots?

As you will know, slots come down to luck, but there are certain things to consider to help increase your chances of landing a win. This can include RTP and volatility – and our reviews have all the information you will need.

It can also pay to take advantage of deposit bonuses and/or free spin offers, both of which can be used on online slots.

What should I know about new slots?

Besides testing promising new online casinos, we also test all interesting new slots!

We have hundreds of slot reviews and new reviews are added every week. By checking our slots page you’ll always know the most interesting upcoming slots to see which of them will be worth your time and money.

New online slots mean not only new innovative features but online casinos often offer promotions for you to test the new games for free.
