Slot machines are an online casino staple – from first-time gamers to seasoned pros, everyone loves a spin of the reels. While slots are renowned for their accessibility, simplicity and high entertainment value (the reason why they have such a strong appeal to new and inexperienced gamers), they’re also well-known for generating some of the biggest payouts of any online casino game genre. While the chances of bagging a win with any online slot title will always depend on its RTP (Return to Player) rate, it is certainly possible to generate multi-million-pound payouts with the right progressive jackpot slot and a lot of luck. Over the years, there have been a few notable examples of online gamblers who were lucky enough to win monumental slot machine jackpots, often based on minuscule real money wagers from as little as 0.25. If you’re an online reel spinner and you’re looking for a dose of inspiration, check out this selection of the biggest online casino slot machine jackpot winners, updated for 2022:
