real money slots games and jackpots

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.
