The Top 10 Online Slot Machines

As a slots afficianado and having played most online slots, I thought it would be fun to create a list of what I consider to be the Top 10 online slot machines. While a lot of this input is personal, I have also taken into account general opinions gleaned from the player forums that I particpate in, moderate, or simply read.

I’ve limited the list to the main software providers – those that I know provide a fair game – and all of these slots can be found across a number of online casinos. These include, Microgaming, RTG, Cryptologic, Wagerworks (Flash only) and Playtech. Of those, Cryptologic, Wagerworks and Playtech do not, at present, accept USA residents. I have included links to the casinos where I play the slots in this list, and it’s worth mentioning that you can sign up as a “guest” at any of the casinos to try them out for yourself.

So here goes…in order of preference:

#1 Thunderstruck

This is the granddady of all free spins slots and is available at Microgaming casinos. Three or more scatters awards 15 free spins where all wins are trebled, and the free spins can retrigger if you get another 3 or more scatters during the spins. The paytable is well balanced for some good wins (medium variance) in normal mode and a wild symbol is present on all reels. The Number 1 slot for 3 years and set to continue as the most popular online slot – and that’s a general concensus. Also note that “Spring Break”, “Summertime” and “Ladies Nite” on the same platform are exact clones. Read the Thunderstruck review…

#2 Cleopatra

Cleopatra is a Wagerworks Flash-only slot following the format of the popular IGT Las Vegas slot of the same name. No surprise considering IGT own Wagerworks! Like Thunderstruck, you get 15 Free spins, all wins trebled in the bonus round, triggered by 3 or more scatters and with retriggers. The only difference is that Cleopatra is a 20-line slot.

#3 Hitman

Hitman is a new (as I write) slot from Microgaming, based on the PC FPS game from Eidos and with stunning graphics and sounds. Three different bonus rounds including an 18 free spins/all winds doubled, plus an expanding wild symbol. Excellent entertainment with some potentially huge wins. Read my Hitman slot review…

#4 Avalon

Yet another Microgaming slot with free spins – this time 12 with a random multiplier between 2x and 7x, plus an additional wild symbol during the free spins. Low/Medium variance – so you get a good run for your money – retriggers during the free spins and good entertainment all round. Had some great hits during the free spins. Read my Avalon slot review…

#5 Aladdin’s Wishes

Aladdin’s Wishes is an RTG Real Series slot with a free spins bonus (surprise!) of 25 spins and a “random jackpot” of at least £1,000, normally much more. Actually you are not always guaranteed the free spins during the bonus – depends if you pick the Genie from the lamps – but its a good slot for decent wins during normal play and marginally my favourite on the RTG platform.

#6 Ronin

Another RTG “Real Series” slot with a random jackpot (minimum £1,000) and three seperate bonus rounds, all triggered by 3 or more scatters (including one on Reel 3) and selected randomly. Each bonus round comprises free spins and can retrigger. It’s one of those slots that can eat and eat, but a good bonus round can really pay back big time, which is why I like it so much.

Play Ronin at: iNetBet, [Club USA]

#7 Isis

A high variance free spins slot for the high rollers with some huge payouts on certain symbols and an excellent 20-30 free spins at 6x multiplier depending on whether you get 3, 4 or 5 scatters. This slot is not for the faint hearted. Long dry spells and the occasional monster hit makes it frustrating at times, beautiful at other! The slot “Supe It Up” on the same platform is a replica of Isis with a car theme incidentally. Read my Isis slot review…

#8 50,000 Pyramid

This is a Wagerworks slot that I work my way to after Cleopatra. The bonus round, triggered by 3 or more scatters, is a pyramid where you pick free spins and multipliers up to a maximum of 40 at 7x. Can be frustrating when you hit the bonus only to get 8 at 1x, but the free spins are pretty frequent which keeps the fun factor flowing. No retriggers on this one, but the scatters pay during the free spins. Read my 50,000 Pyramid slot review…

#9. Kathmandu

A Microgaming slot with 15 free spins at a random multiplier between 2x and 5x. The free spins pay a little less than other slots like the aforementioned Avalon, which is a similar principle, but happen reasonably regularly when 3 “bell” scatters are in view. The free spins can retrigger and there are lots of small/half-decent payouts in normal play making this a decent low-rolling slot.

Play Kathmandu at: 32Red, Roxy Palace, [Mummys Gold], [King Neptunes] (USA)

#10 Desert Treasure

The only Playtech slot to make my list, and one for low rollers. It’s hard to get a really really high payout, though it can happen and I’ve had 500x bet on the odd occasion, but generally it keeps you going a long time and has lots of half-decent wins, along with two bonus rounds – one a free spins (10 at 3x) and one a “pick ’em” style bonus. There’s something about this slot, even though it’s a low variance slot.
