No more going to the casino, for example, because with online slots you can spin those reels as much as you want from your own home! 

And it’s not just this fact that online slots have resulted in, because online slot titles these days can be monumentally complex, with all manner of different game mechanics, themes and bonus rounds available – check out our blog here. Gamblers just cannot get enough of online slots, and there isn’t any surprise when you consider how good some of the top slot games of all time are. Keep reading for our rundown of the top 5 slots games of all time. 


Centurion by Inspired Gaming is a relatively new slot, something that is immediately evident when you start playing it due to its outrageously good HD graphics, and tailor made mini-game-esque style bonus features. The developer has gone with an Ancient Roman theme here, with particular emphasis on the Roman legions and amphitheatres. 

Whilst this online slot is wonderful to look at, the real selling point is in its gameplay, which utilizes a range of modern features to ensure an exceptionally exciting gambling experience. And its lucrative too, with a maximum slot win that can easily exceed 5,000x your wager. Nice! 

Rainbow Riches Pick N Mix 

The Rainbow Riches slot series is almost definitely the most iconic that the slots industry has ever seen, with the first Barcrest Rainbow Riches slot machine coming out all the way back in the 60s. Since then the Rainbow Riches franchise has become immensely popular, and has also pretty much singlehandedly commercialised the “luck of the Irish” theme too. 

Whilst many of the Rainbow Riches slot games are incredibly good, there is no beating Rainbow Riches Pick N Mix, which goes straight into our top 5 slot games of all time. The reason why? Rainbow Riches Pick N Mix features all of the best bonus rounds from previous Rainbow Riches games, something that ultimately results in a crazy 99% RTP rating. 

Mega Moolah 

Huge slot jackpot hunters can’t speak highly enough of the Microgaming slot Mega Moolah, and this is because its progressive jackpot system has paid out over a million to several people in the last few years alone. 

The cartoon style safari theme is also a great plus! 

The Codfather 

Sometimes it’s the comedy element that makes people love certain online slots, and NextGen Gaming’s The Codfather is a perfect example. Ever wondered what a marine mafia boss would look like? Look no further than The Codfather.


Bonanza by Big Time Gaming was the first slot from the new developer to go truly viral, mainly as a result of its incredibly unique and innovative Megaways game mechanic.
