Slots, table games, progressive jackpot slots, video poker, Live Casino, Mobile Casino, and specialty games. Just so you know, the majority of the games are slots.

The UK Casino further divides the slot games into classics, 3D, video slots, and progressive slots. Before you risk your money there is a free slots version too.



Online slots are the beating heart of any UK online casino. Brits love them because they require no skill and they pay out vast sums of money on a single spin.

Slot games offer RTPs in excess of 94% right to 100%. They can be low, medium, or high variance with jackpots of up to 80,000x your stake.

And slots vendors pad them out with Free Spins that have majestic multipliers of up to 50x. The multipliers can also combine to give you an even bigger multiplier of up to 60x!

The remainder of the in-game bonus rounds is Re-spins, standard wilds, Sticky, Shifting, or Expanding wilds. The last bit is the Pick Me game where you click on special symbols to reveal a cash prize.


Best UK Casinos Slots

“Best” can have a negative connotation sometimes because it can sound misleading. We dig the Megaways slots for sure. Therefore, we list the Casinowhizz’ team’s top slots for real money at the moment:

  1. Legacy of The Gods – With its Greek mythology theme it gives you a choice of four Free Spins options with varying degrees of volatility. It offers an RTP of 96.5% and a jackpot of 50,000x your stake.
  2. Blazing Bull – Kalamba Gaming reinforces a popular theme with multipliers of up to 50x in the Free Spins. With an RTP of 97.42%, high hit frequency, and a maximum cash prize of 2,667x your stake. Players will different bankrolls will enjoy the game.

It has Free Spins with big multipliers, gorgeous graphics, a jackpot of 10,000x your stake. And, let’s not forget the RTP of 96.27%. We also advise caution though because the volatility is sharp.
  4. Megah Moolah Absolootely Mad – Microgaming takes progressive jackpot slots to a new level with this release. There’s enough in it to drive any player wild. Not to mention that it offers a nice little windfall of £1 million.
