Mad Casino games review — a big lobby, and how to read it

Reviewed by Callum Reid · Last checked 7 October 2026

The game library scores 8 out of 10. The catalogue is large and built on studios with long track records, but a big number tells you little on its own. Here is how we judged it and what you should look at before spinning.

Size and suppliers

More than 2,000 slots are advertised. The names that matter most to UK players are present: Pragmatic Play, whose Sweet Bonanza, Gates of Olympus and Big Bass titles fill most modern lobbies; NetEnt, behind long-running classics; and Play'n GO, whose Book of Dead remains one of the most-played slots in Britain. Games from established studios are independently tested before release, which is one reason we weight supplier quality above raw numbers.

RTP versions: the check most players skip

Return to player is a long-run average, not a prediction for a session. Several big studios release the same slot at more than one RTP level, sometimes several percentage points apart, and the casino chooses which to offer. Open the information or paytable screen before playing and look for the stated RTP. If a favourite title shows a noticeably lower figure than you have seen elsewhere, you are playing a lower-paying configuration. We cannot audit every title, so we treat this as something each reader should verify and have not given the lobby full marks.

Tournaments

Slot tournaments run alongside the main lobby. Leaderboards usually reward volume of play or biggest multipliers, which means they favour heavier players. Read how points are earned before joining and do not chase a leaderboard position with higher stakes than you planned.

Finding your way round

With a lobby this size, filters by studio and game type matter more than banners. Bonus players should also check the excluded-games list in the bonus terms, because some high-RTP and jackpot titles do not count towards wagering. Playing one of those by accident while a bonus is active wastes stakes.

Our score

Full marks for supplier quality, a deduction for the variable RTP question and a smaller one because a catalogue of this size inevitably includes filler. Eight out of ten.
