This page will shine a light on all of the above topics, whilst also helping to point you in the direction of our top recommended casino games.

Online Slots

Online slots are typically the most popular type of casino game for several key reasons. Their potential to deliver huge wins via a single spin of the reels is unmatched by any other iGaming genre. Also, the inclusion of many special features such as free spins, win multipliers and random bonuses help to keep the gameplay fresh and interesting at all times. Jackpot slots are also increasingly popular.

The biggest problem you’ll face, however, is that as there are so many to choose from it can be difficult to figure out where to begin. That’s why, below, we’ve selected 5 of the best online slots currently available. Each game offers a unique array of mechanics and bonuses that help them to stand out from the crowd. So, if you’re looking for somewhere to get started, we highly recommend the following slot games. They’ll provide a superb introduction to the world of reel-spinning action and from there your options are endless!


NetEnt’s Starburst is the perennial classic online slot. Its straightforward gameplay provides an uncomplicated introduction to what could become a magical slots adventure. You simply need to land matching symbols on adjacent reels for a win – it doesn’t get much simpler. Better yet, these symbols pay in both directions courtesy of the pay both ways mechanic. That means you can create wins both left to right and right to left. There’s also a Respin feature that can trigger multiple times to further enhance your chances of hitting big wins worth up to 500x your stake. Additionally, Starbust is routinely in free spins offers at casinos.

Book of Dead

The ‘Book of’ slots genre has given rise to a great many releases but one of the most popular to have ever launched is Book of Dead by Play’N Go. Played on a standard 5×3 grid, you simply need to land matching symbols on a payline for a win. However, what makes this slot stand out is its free spins bonus. Land 3 or more Scatter symbols and you’ll trigger a free spins feature that improves the game’s payout potential via special expanding symbols. Land the required number of symbols and they’ll expand to cover each reel and create the maximum win lines, irrespective of their position on the reels. Furthermore, retriggers offer extra free spins and additional expanding symbols for even bigger wins!


One of Big Time Gaming’s most successful releases, Bonanza introduces players to the innovative Megaways mechanic. Each of the 6 reels can deliver between 2-7 symbols, which can create up to a staggering 117,649 ways to win. As if that wasn’t enough, free spins include an unlimited progressive multiplier that increases with each successful win. Bonanza does feature high volatility gameplay but with a 10,000x maximum win up for grabs, it’s easy to see why it’s a go-to for many players.


Again, Play’N Go features on our top recommended online slots list thanks to the provider’s immensely successful Reactoonz release. This particular game deviates from the standard gameplay model due to its cluster pays mechanic, whereby you’ll need to connect matching symbols vertically or horizontally. As you do, they’ll disappear from the grid and new symbols will appear. You’ll trigger special features as you rack up wins that will help you to unlock the main bonus, which introduces a special 3×3 wild symbol to the grid for huge wins worth up to 4,570x!

Immortal Romance

Another online slot that’s stood the test of time is Microgaming’s Immortal Romance. Much of the reason for its popularity is thanks to its high RTP along with a combination of free spins and multipliers. Gameplay unfolds across 5 reels, which provide a total of 243 ways to win – you’ll still need symbols to land on adjacent reels but not on a traditional payline. You can benefit from wild reels during the base game and 3 or more Scatters grant access to the Chamber of Spins, where 4 special free spins features are available.

Online Slingo
