Online Slots with the Lowest RTPs (Progressive Jackpot Slots)
While high RTPs often correlate with the best payout online slots in the UK, it’s also valuable to understand which ones have the lowest RTPs. Despite their lower RTPs, these progressive jackpot games offer larger maximum wins as each stake wagered on them across the network – which can be thousands of players belonging to thousands of casinos – adds to a collective prize pot.
So although, in the long run, the balance of money vs winning returns is heavily in favour of the casino, you could always land a substantial payout with a single spin – like Jon Heywood did in 2015 when he won £13.2m playing Mega Moola.
Slots with the worst RTP but huge top prizes are:
- Mega Moolah (Microgaming): RTP 88.12%
- Major Millions (Microgaming): RTP 89.37%
- King Cashalot (Microgaming): RTP 90.59%
- Gladiator Jackpot (Playtech): RTP 91.46%
- Jackpot Giant (Playtech): RTP 94.22%
- Beach Life (Playtech): RTP 93.25%
- Hall of Gods (NetEnt): RTP 95.5%
- Arabian Nights (NetEnt): RTP 95.6%
- Age of the Gods (Playtech): RTP 95.02%
- Mega Fortune (NetEnt): RTP 96.6%
Understanding RTPs in Online Slots (House Edge)
Every licensed online casino in the UK programs a payout percentage into its slot games. As mentioned above, this theoretical figure is based on spins over time.
For instance, a slot with an RTP of 97% would pay out an average of £97 for every £100 staked. The casino keeps the remaining amount – £3 in this case – this is the casino’s house edge.
The highest payout online slots sites prioritise featuring games with high RTP percentages. Among the best online slots payout percentage UK sites are bet365, Betfred, and 10Bet. These platforms are recognised as some of the best payout casinos in the UK.
These sites host a range of games, from bonus slots boasting RTPs of 98% to progressive jackpots that pay out massive sums, providing some of the best payout online slot game experiences. They cater to every player, offering top payout online slots for those seeking significant returns.

Other Best Payout Slots Considerations

Also, make sure you play responsibly and choose online casinos that are licensed and regulated by the UK Gambling Commission to guarantee your only ever gamble at a platform that provides a safe and fair gaming environment.
Finally, regardless of the payout rate of a slot, only ever play with cash you can afford to lose.
