6 Most Popular Slots

6 Most Popular Slots

Elsewhere in our online casino blog, we’ve taken a look at some of the most unique slots available in our collection here at Bet UK, but distinctive and unusual themes, mechanics, and bonuses don’t necessarily equate to making a slot popular. To this end, we’ve done some research into which of our online casino slot offerings continue to be some of the most frequently played, and what exactly makes them so sought after by our players. We’ve narrowed it down to a list of six that offers some diversity, but the truth is that it could have been much longer, such are the number of titles that are loaded up on a consistent basis.

What Makes A Slot Popular?

When it comes to what makes a slot popular, you have to look at several aspects. A lot of slots gain intrigue through word of mouth or associated promotions, and you’ll see some examples of each of those on our shortlist. Others seem to garner attention via their strong themes and graphics, which a lot of modern slots players look for. Then there are those that began life in land-based casino forms and have been modified to suit an online environment. Some players look for elements of all of the above when they choose a new slot game, and some have their feet firmly planted in one particular camp, but all in all, those are the key areas that have led to the below slots making it onto the most played index.

What Are The Most Popular Slots?

Just before we reveal our shortlist of the six most popular slots, it’s worth mentioning that all of them are available to play in demo format, so you can get a proper feel for any that are of interest to you without having to commit to using your own balance. So, even if you’re just curious to see what all the fuss is about when it comes to a title outside of your comfort zone, you don’t have to go anywhere else to experience them in all their glory.

Big Wheel

Perhaps a surprising inclusion from the get-go, Big Wheel slot presents a fantastically simple layout that harks back to the days before online casinos when pub fruit machines were all the rage. With just a single payline in play, players that are used to contemporary slot structures may be a little nonplussed, but for those that are classic slot aficionados, Big Wheel presents a wonderfully nostalgic experience. Only five symbols can appear across the three reels, with Cherries, Oranges, Bells, and Grapes joined by the higher paying Duck icons, three of which can also trigger a chance at a repeat win. The titular Big Wheel feature can award some rudimentary yet valuable bonuses, including Round About, Roller Coaster, Crazy Reels, Ring The Bell, and Duck Shoot.

Book of Dead

Book of Dead is arguably one of the greatest titles ever to grace slot machines, both in land-based and online casinos. Play N Go played a masterstroke when they created this game, where the five reels are set across the backdrop of a vast Egyptian tomb, which innately adds to the gravitas of the slot. The wider visuals are also complemented by the stunning hieroglyphics inspired symbols, which range from playing card values of 10-A to higher value Egyptian deities of Horus, Anubis, and Osiris. The best paying of the lot is the explorer, Rich Wilde, and players who enjoy investigating the aspects of slot games in minute detail may well find a kindred spirit here. So sacred is the mythos surrounding Book of Dead, that it is one of the few classics that hasn’t yet been refashioned into the likes of a Megaways slot or a similar sequel.

We swiftly move from exploring ancient tombs to travelling back in time to the days when the Roman Empire was in its heyday, which is the setting for Centurion slot. A cartoonish Centurion lurks behind the foliage to the right-hand side of the reels, which may initially appear to be part of the charm, but it’s he who can award a wide variety of base game modifiers. These include Five of a Kind - which guarantees a payline filled with a symbol chosen at random, Big Win - which ensures a win formed by the highest paying symbol, Super Bonus Reels - which adds additional scatters to potentially unlock the main bonus rounds, and Reelus Maximus - which adds a colossal 3x3 symbols to the centre of the reels. All of these can prove fantastic, but the Free Spins, pick me, and trail rounds offered by the Bonus Wheel can be even more valuable. The success of the slot has led to adaptations in the form of Slingo Centurion and Centurion Megaways.

You may have heard of the Starburst slot through Free Spins bonus offers, which you could be forgiven for thinking solely contributes to this NetEnt title’s immense popularity. However, that isn’t the full picture, as this casino offering has plenty of depth to it. With an arcade feel combined with futuristic graphics, the Starburst slot is stunning to look at, and the gameplay and layout are easy to follow. The fact you can win from right to left as well as left to right is another huge boost and the kind of modern feature that a lot of players look out for. That said, the Starburst Wilds is the main feature that you’re likely to want to keep an eye out for. They can appear across any of the middle three reels, expanding to cover all the positions of that reel, before a respin is awarded. Further Starburst Wilds can land, with the process repeating itself until all three middle reels are covered. This feature can lead to a win of 500x your stake.

Bet UK’s Most Popular Slots

So there we have it, six of the most popular slots here at Bet UK. While we have many more titles that are played by a whole host of our community, there is a noticeable trend across the ones we’ve included here, namely that despite the fancy Megaways mechanic and the Slingo phenomenon, you seemingly can’t beat a classic slot structure. That’s perhaps the reason that the likes of Starburst have been such a success in recent years, as the graphics are the driving force behind what is ultimately a straightforward composition. However, with the bonus-packed Centurion making an appearance, it remains to be seen if modern players will continue to flock to the archetypal slot format, or if they’ll be after something a bit more unique like Odin Infinity Reels and Star Clusters.
