Do you love a flutter on the slots? Find the best games and casino bonus offers here at Slot Sites. We have been helping players to find the top deals and games since 2011!

Slot machine have come a long way since they first went online in the late 1990s. In the early days, the games were pretty basic compared to what you would find on the casino floors of Las Vegas, Monaco or Macau.

That is no longer the case! Fast forward to today, and the tables, or should we say the machines, have turned. Land-based slots often lag behind online slot games. They are feature rich, bonus heavy and evolving fast.

Which are the Best Slots?

That’s not an easy question. With so much choice on the Internet, it’s practically impossible to single out the best slots out there as everybody’s taste is different.

But we never duck a challenge! You may not agree, but for us these are some of the best games out there. These are pure entertainment.

The Stars of the Show

Our “out and out favourites”, if we had to pick a top 5 are Starburst, Sweet Bonanza Esqueleto Explosivo, Book of Dead and Wild Wild West.

We also spend quite a bit of time on Playtech slots- games like King of Olympus (from the Age of the Gods range), Epic Ape and Top Gun. They have some fantastic games themed on movie blockbusters.

Their DC Comics range like Batman, Superman II and Green Lantern are firm favourites, and Gladiator remains a classic despite its age.

Microgaming (or Games Global as they are known these days) have some classics under their belt with games like Mermaids Millions, Immortal Romance and Thunderstruck 2. These days, they work with smaller innovative studios like Gameburger who are launching smash hits like 9 Pots of Gold and 9 Masks of Fire which have some big scatter pay jackpots.

Then there are the IGT slots you’ll be familiar with if you have ever been to Vegas. Games like Siberian Storm, Pixies of The Forest (with tumbling reels) and Cleopatra should need no introduction.

Swedish Slot Gurus

guns n roses slot

NetEnt games like Gonzo’s Quest, Finn and the Swirly Spin, Narcos, Starburst and the Guns ‘n Roses slot deserve a mention. It is no exaggeration to say that this developer has “upped the ante” with the quality of the graphics and their innovation on game-play.

And if you are looking for more Swedish stars, then check out Play’n Go. This design studio continues to push out new games at a pace, with titles like Athena Ascending, Rise of Merlin, Clash of Camelot and Reactoonz all making a big splash on the scene. The original Book of Dead remains their most popular release.

Nolimit City is also making waves with popular titles including Deadwood, San Quentin, and El Paso Gunfire X-Nudge. They are pretty famous for their high volatility games like Punk Rocker.

Keep coming back for new games on Slot Sites- we are building out the best of Games Global (Microgaming), Playtech, Next Gen and IGT games as well as adding more ELK and Thunderkick titles, as well as a range of Megaways slots from Big Time Gaming and other suppliers.

The variety on the Internet is incredible- the sky is the limit!

Slot Tip

Decide how you like your slots. Do you prefer more frequent, lower payouts or less frequent higher payouts? Then choose a low volatility slot for the former and a high volatility slot for the latter. We cover slot variance in our game reviews.

Other games we are looking at include Western Gold 2 from Just for the Win and Microgaming, Dungeons and Diamonds, Golden Catch from Big Time Gaming and the Funk Master slot from Net Ent (we love the soundtrack on this one).

Western Gold 2 (Double Barrel) has an RTP of 96.15% and claims to be double the fun of the original game. This sequel is bigger, better, and more exciting. The Wild West dusty small town invites you to collect golden horseshoes and find hidden treasures. Spin a special feature barrel to boost your Free Spins with multipliers and cash prize upgrades plus a chance at the generous Super Free Spins. Sounds good!

Progressive Jackpots

The slots jackpots continue to head up on many casino sites. The number of games you’ll find online surpassed Las Vegas a long time ago, and while the big progressive jackpots are not quite at the level of the $39.7 million won on the Megabucks slot (an offline IGT network) at the Excalibur, they are catching up with prize pools in millions thanks to the networking power of the web. And the trend is upwards.

In 2013 a player from Finland won $24 million on NetEnt’s Mega Fortune. And there have been multiple 8 figure wins on Microgaming’s Mega Moolah jackpot including a new world record of the top jackpot prize in April 2021 when a Belgian player won $23.5m on the Absolootly Mad Mega Moolah slot game. The WowPot Mega jackpot is also making waves these days.

mobile slots

The big area of development in the last 5 years has been in the field of mobile slots. The latest phones like the iPhone 14 and the Samsung Galaxy S22 are fast. Combine that with quicker connection speeds and playing slots on your mobile or tablet has never been more entertaining.

Just try playing the Guns ‘n Roses slot on an iPhone 14 Pro or the latest Google Pixel 7, for example. We prefer playing on a phone versus a laptop these days!

Developers like ELK and Thunderkick have always specialises in designing games for smaller screens. is fully optimised for mobile- we will recognise your device and display the best slot games that are compatible with your phone or tablet. All you need to do is tap and swipe.

Slots Providers

If there is one area that has seen huge growth in the online slots world, it is in the development of the games. There a number reasons for this, including:

  • Growth of the overall slots market.
  • Faster internet connections and more powerful devices (laptops, tablets, smart-phones).
  • Growth of the smaller design houses. Companies like NetEnt have spawned whole ecosystems including newer design studios like ELK and Play ‘n Go.

The slots landscape today is very different to 20 years ago when there were 5 main game developers including Microgaming, Playtech and IGT.

Newer kids on the block like Gameburger, ELK, Blueprint, Thunderkick, Play’n Go, Slingshot, Neon and many other smaller studios working are producing top quality, innovative games that the long established players are struggling to match. In some cases (Games Global/Microgaming), the bigger companies are working with the smaller design houses like Stormcraft and Just For the Win to help distribute their games. For a fee of course.
