In these scheduled tournaments, players compete against each other for cash prizes or other exciting rewards. While the base game may deliver more frequent wins, it is the bonus round that unlocks premium symbols with the largest multipliers for the biggest payouts. UK players have also claimed impressive jackpots, such as £6.3 million on Hall of Gods, £6.2 million on Jackpot Giant and £5.1 million on Beach Life. These individual slot games can still pay out staggering jackpots, including the €17.9 million won on Mega Fortune by a Finnish player. However, WowPot regained its crown with a world-record online slots jackpot win of £33 million, won in late 2023 on the aptly named Wheel of Wishes. The biggest online progressive jackpot payouts have primarily come from the WowPot and Mega Moolah series of slot games. Such massive potential wins are among the reasons why Nolimit City slots have become a favourite for many UK players. However, Nolimit City’s Tombstone RIP now tops the charts with an unprecedented 300,000 max payout, which was first hit shortly after its release in 2022.
