Madslots Review

Sue Dawson

Rating: 4.8/5

Rating: 4.8/5

Madslots is new for 2023, on a platform that’s a refreshing change from the usual skin sites.


MadSlots is on a casino platform and license provided by Viral Interactive and is one of only a couple of this type of site currently available to UK players.  It’s associated with the rapidly expanding Skywind Group who also own the now closed InTouch group of sites and this explains why MadSlots offers some Slot Factory games which were previously only available at InTouch sites.

Rather than having a lot of different games categories in the lobby or a filtering system, MadSlots serves up curated selections of games, grouped by theme (e.g. jokers, Book Of, fishing), on the casino home page on all devices.  These can be very handy if you’re not sure what to play and are searching for inspiration, if you know what you like and are looking for more of the same, or even if you just want to see all of Pragmatic Play’s Drops & Wins slots in the same place.  Alternatively you can search for games by name, look in the New and/or Popular sections or browse through hundreds of games (1800+, they say) in the Slots or All Games area.

What they don’t appear to have at MadSlots is any progressive jackpots; there’s no area for them in the lobby and a search for known titles turned up blank.

There’s also a live casino area which is largely focused on blackjack and baccarat, with a bit of roulette, and most of the games are by Pragmatic Play.  There’s just one game show – Mega Wheel.

One very innovative feature at MadSlots is the Live RTP page.  This shows the actual RTP for a selection of slot games whch have been played over the last hour (updated every 3 seconds) and over the last 24 hours (updated every 3 minutes).  In each case the 12 games with the highest actual RTP show up in the Hot section and the 12 games with the lowest actual RTP show up in the Cold section. It’s certainly interesting to see just how volatile some very popular games are and which games are currently being played a lot, but important to recognise that past returns on slot games are not a guide to future returns.

Another area of innovation is the deposit methods they offer, including Trustly which is rapidly increasing in popularity and Fonix, a mobile phone billing solution.  It’s common for online casinos to charge players through the nose for using mobile phone billing to deposit, but this is absolutely not the case at MadSlots – Fonix is free to use.

In order to deposit or withdraw via any method you will need to validate your account. For a start, you’ll need a mobile phone as the very first step after picking a password is to enter a code that will be sent by SMS.  After supplying your details, you’ll be asked to upload documents to prove your identity and address .

The promotions page at MadSlots looks very promising. When we visited there were three different deposit offers valid on different days of the week plus Pragmatic’s Drops & Wins and a similar promotion run by game provider Wazdan – so plenty for players to engage with.

With a different to usual range of games, some great features and promotions and a super generous welcome offer, MadSlots is sure to be a hit with UK players.

  • Safer Gambling Provision

    Unusually the Safer Gambling policy statement at MadSlots is all about external sources of help such as Gamstop and ad/transaction blocking rather than about what they have on site.  For information about safer gambling tools, you need to look in the site terms & conditions – and even there it only goes into detail about timeout and self exclusion.  Limits are mentioned but you need an account to see what’s available.  In fact, they have two types of limits – daily, weekly and monthly deposit limits which are exactly what you’d expect, and an affordability limit (a net deposit limit) which is set by the casino, taking into account any other accounts you may have with associated brands.  You can apply to have this raised but you’ll have to supply proof of affordability.
