Browse Slots by Feature

In the online slots world, developers are always dreaming up new ways to capture players attention. So, we’ve made it is easy for you to browse slots by the features that you enjoy most. Simply click on a feature and you’ll find all of the free slots that include it! 

Browse Slots by Volatility 

Volatility level is important in slots, particularly with regards to bankroll management. We always advise keeping the volatility level in mind when choosing a new game to play, as it will have an important effect on your experience. 

  • Low variance slots: The payouts  in low volatility slots are smaller than you’ll find in other games but these slots offer prizes much more frequently. 

  • Medium variance slots: These games award a nice balance of larger and smaller wins, at pretty consistent frequency. 

  • High variance slots: these games have much higher max wins others, but their prizes are paid out a lot less often so you could be left waiting a while in between wins. 

Most Popular Slot Features

Some types of online slots features are just classic. They are found in tons of slots across the web, and with good reason – they just make the gameplay better. Here are some of the most popular slot features that you should try out if you haven’t yet. 

Free Spins

Common in the vast majority of online slots, free spins allow you to spin the reels without having to wager any cash. They are normally triggered by landing 3 or more scatters, and they can sometimes come with additional features like multiplied wins or extra wilds. 


While Megaways are relatively new, they are incredibly common. These types of slot games have variable winning ways. Most games offer up to 117,649 ways to win but there are some that have over a million. 


These games create wins when symbols land in groups rather than on paylines, and they usually cause cascades.

Hold and Win Respins

This is a bonus round where you can collect cash prizes. As you land symbols on the reels, they are held in place and the rest of the reels respin.

New Slot Innovations

It’s also a good idea to stay-up-to-date with the latest slot trends, as you never know when something new is going to come along that really tickles your fancy.

So, here are some of the freshest features to make their debut in the slots market that we’d recommend trying: 

Slots With Bonus Meters 

Bonus meters are a new addition slot games, allowing you to charge up certain features by collecting symbols.

Slots With Multiple Reel Sets

Why have one set of reels when you could have two – or four?! In some slots like Gorilla Gold Megaways, you start out with four reels. In others, like Butterfly Staxx 2, you have to unlock them in the bonus round. Either way, the fun is multiplied!  

Infinity Reels and Infinireels

Infinity Reels (from ReelPlay) and Infinireels (from NetEnt) are slots with reels that expand horizontally. In most games, your multiplier increases as you add more reels. 

Reel Modifiers 

Reel modifiers are little features that can appear at any time during a slot’s base game or free spins round.

Maybe extra wilds are randomly added, maybe colossal symbols drop down onto the reels from time to time, maybe low-paying symbols are removed - whatever it is, they are random and there are lots of them.

Multi-Level Bonus

These type of slot games allow you to progress from one level to another in their bonuses. Each new level offers bigger and better prizes, so you can work your way up to impressive winnings. 

Are Slots With More Features Better?

In the slots market, it’s not always the best course of action to play the games with the most bonuses on offer. Some feature-rich slots are fantastic but others can fall flat – while some scaled-back slot games are loads of fun. 

Simple Yet Effective

Take Starburst, for example. This game only has one bonus feature – expanding wild respins. It sounds a bit boring -but, then you give it a spin and it delivers all sorts of action. Reactoonz 2 is the opposite – it comes loaded with features but the gameplay is confusing and not entirely interesting. 

Play Free Slots to Discover Your Favorite Features

This is why we always recommend playing free play slots before you decide to wager real-money on any specific game. You should really see why a game like is in action, so you don’t end up spending money on a game with features that sound great in theory but just don’t work out well in practice.
