Low volatility slots offer a gameplay style involving smaller prizes awarded at more regular intervals. The most famous low volatility game is the Starburst slot from NetEnt, though there are other popular low volatility slots including Fishin’ Frenzy, God of Storms, Reel King Mega and Clover Rollover 2.

This year has been an epic one for new online slots, with many of the hundreds of new slots going straight into the top 100 popular UK slots. Rising Rewards from Triple Edge Studios has been a massive hit, while Eggs Bonanza, Big Bass Amazon Xtreme, The Goonies Hey You Guys and Eye of Horus Rise of Egypt have also made waves.

High volatility slots like Book of Dead are favoured by slots players who enjoy playing for the chance to play for extremely big prizes that are less frequently awarded. Games like Book of Dead and Big Bass Splash are some of the best high volatility slots, with Bonanza, Fluffy Favourites, Gates of Olympus and Money Train 4 running them close.

These days, every slot is made for mobile phones, so all of our popular slots work super well on your smartphone. But there are some games like Cygnus 2, 777 Strike and Mustang Gold that show us what’s truly possible from a phone slots experience.

There are scores of different slot themes with new genres being created by providers every year. The most popular slot themes, if you go by the sheer number of best slots games, are Irish slots like 9 Pots of Gold, ancient civilisation slots like Age of the Gods, animal slots like Wolf Gold and ancient Egypt slots like Legacy of Dead.

PlayOJO offers games from over 60 different UK slot providers, from massive global companies like IGT to independent game studios like ELK. Ask players whose games they love, and you’ll probably hear names like Pragmatic Play, Eyecon, Blueprint Gaming, Play’n GO and Red Tiger, though there are many more who are releasing popular slots too.

Big Bass Bonanza and Big Bass Splash are the two most popular slots at PlayOJO, alongside older games like Starburst and Book of Dead. Playtech’s recent releases Sahara Riches Cash Collect and God of Storms are also considered some of the best slots online.

It’s difficult to know why some slots like Starburst become instant sensations, but the top slot games often have a distinctive theme, outstanding graphics and animations, and a great set of bonus features. That’s the minimum these days expected by the discerning slots player community.
