Highest paying slot games for UK players
Not all online slots are created equal, with some offering better chances of a payout than others. While there’s no way of guaranteeing a win, choosing slot games with higher return to player percentages (RTP) will theoretically give you a better chance at winning real money.
RTP is displayed as a percentage and indicates how much of your money you can expect to get back when playing a casino game over time. The industry average is 96%, but the best online slot payout percentages are 98% and higher. Give these high-paying slots a try to increase your chances of winning when you spin the reels:

The 5-reel, 10-payline slot has a 96.09% RTP and is optimised for play on all devices, including iPhone and Android.

Online slot game features
We’ve already mentioned some of the key features you’ll come across when playing UK online slots, such as symbols and wilds. In this section, we’ll breakdown what each of those mean:
Symbols are the icons that land in place after you spin the reels. Most slot games feature playing cards (Jack, Queen, King and Ace) as lower-paying symbols, while the high-paying symbols typically mirror the slot’s theme. You’ll also find bonus symbols, such as wilds and scatters in modern slots.
Paylines are the invisible lines on which a payout is awarded based on a winning combination of symbols. Classic online slots typically have 10 paylines, but you can find new online slots with hundreds of thousands of paylines. You’ll usually need to match three or more symbols on an active payline to secure a payout.
Online slots with free spins are some of the most-played slot games, as they offer you the chance to spin the reels risk-free. Moreover, a game’s max win or jackpot can usually be triggered during a free spins bonus. Typically, three or more scatter symbols will activate a free spins round, but this will vary depending on the software provider.
Wilds are a special type of symbol that can substitute for all other symbols (except the scatter) to help you land a winning combination. In some games, these can also transform into expanding or sticky wilds to boost your payout.
Scatter symbols can trigger a variety of bonus features. As the name suggests, they don’t need to land on a fixed payline to activate, but can appear scattered across the reels as long as the required number is showing (usually three).
Bonus online slots are incredibly fun to play as they trigger mini-games such as pick-me, spin-the-wheel, respins and more. These games provide additional gameplay to help you maximise your winnings and land instant cash prizes.
