The first online video slot to introduce a bonus round, Reel ‘Em In, was launched in 1996, marking a major milestone in the evolution of online slots. The first online slots available in the UK were simple, typically played across five reels and three rows. Megaways slots are among the most popular formats, offering countless ways to win on every spin. Exclusive to BetMGM are the thrilling MGM Millions games, where classic slots like Starburst feature a ‘mega’ progressive jackpot, which currently stands in excess of £28 million.

Online casino bonuses are incentives offered by casinos to attract new players and reward existing ones. High payout slots, like Gates of Olympus, mix high RTP with big rewards from bonuses, like free spins or multipliers. Many high payout slots add special modifiers such as extra wilds, increasing multipliers or expanding symbols during free spins. UK players can find this slot at licensed casinos. You can try it out at BetMGM Casino, where new players get a £25 casino no-deposit bonus to spin risk-free.
- The 2026 changes to gambling laws mean bonuses must now be capped at 10x wagering, but that could still mean the headline value of the offer is diminished after wagering has been completed.
- New customers online only.
- Progressive Jackpot slots work by taking a portion of each bet and adding it to a jackpot that gets bigger with every wager.
- While you can get more free spins elsewhere, these free spins carry no wagering requirements and punters have a bigger choice of games to use the bonus on than some rival slot sites provide.
