Online Slots With The Best Bonus Features

18+

When playing online slots, bonus features are often one of the most sought out aspects of the game. Free spins, sticky wilds, progressive features, there is a huge list of different slot bonuses that players enjoy.

We’ve put together a list of some games you may not know that have some of the most interesting features. It doesn’t necessarily feature the games you might think – there’s no Starburst, Thunderstruck 2 or Book of Ra Deluxe here.

Instead, we’ve focused on the slot game bonus features, why they work well with the slot and the theme, and what makes them so much fun.

Because it’s better to play games that surprise you, rather than bore you or you’ve tried a hundred times before.

The Invisible Man – NetEnt

NetEnt developed this exceptional slot which is based around the less well-known film from 1933. We love this slot because of its theme. Set against a dark English country village where a scientist discovers the power of invisibility, he then becomes dangerously and murderously insane.

Because of course, he does.

The Invisible Man slot also has a huge array of bonus features that match the theme beautifully.

There are two roaming wilds, one moving left to right and the other right to left which give you a free re-spin of the reels when they show up. One is the invisible man, the other is the policeman and if they meet, mayhem starts with the free spins round.

You also get the opportunity to enjoy two bonus rounds within the free spins, which take place across different locations – keeping the game very interesting.

Yes there are loads of games with Walking Wilds we could have put on this list, from Halloween Jack by NetEnt or even the Wild Seas slot review. But in terms of getting the theme and feature merging beautifully together, we picked The Invisible Man slot.

Hot as Hades – Microgaming

This 5 x 3 reel, 20 line slot is a fun, Greek mythology theme which fully embraces a number of different bonus features.

The ‘Super Mode’ free spin feature is very popular in this game, being triggered randomly and awards players with 5 free spins. This is one of the simplest and most common bonus rounds found on slot games, but can really do wonders for your bankroll.

With this feature, you are guaranteed to be awarded 3 wilds that will remain sticky for the remainder of the bonus games.

Within the game, there is also a bonus game, which is triggered when you land on 3 or more of the Crystal Skulls. The Quest for the Crystal Helm bonus feature is an adventurous trail where you have to work through four rounds characterised by Cerberus, Medusa, Poseidon and Zeus.

In short, The Hot As Hades video slot represents our pick for Microgaming slots that incorporate the features we all know and love in a fun and animated way.

Crown of Egypt – IGT

If you are looking for a gorgeous looking mobile slot which offers 1024 multi-ways to win, this is the game you need to choose.

With interesting graphics flashing on the screen with every win, you are guaranteed to enjoy this real money slot, offering an interesting take on any of the Egyptian themed slots.

The top fixed jackpot stands at 5,000 coins and you can win up to 20 free games which can be retriggered.

Before Megaways you had MultiWay Xtra slots by IGT, which awards pay for matching symbols in any position in adjacent columns starting from the left. If you hit this feature frequently, you are going to be getting some big wins thanks to a generous paytable.

There is also a Free Spins Bonus feature, which is triggered by getting 2 or more Bonus Pyramid symbols on the middle reel. 2 bonus symbols get you 10 free spins, 3 will get you 15 free spins and 4 will get you 20 free spins. The Crown of Egypt slot is simple, but a great way to get started on big win multiple ways to win games.

Castle Builder 2 – Rabcat

This is probably a little bit of a controversial pick because you don’t know whether this is a game or a slot machine… or maybe a little bit of both?

First, you get to pick from 3 different avatars, each with different skill sets. You then have 75 castles you need to build, over 15 different kingdoms and 4 game difficulties which will define how much you win.

In essence, the Castle Builder 2 slot is a 5 reel 15 payline game which you spin to collect building material for your castles. When you finish collecting, you can set up marriages, win cash, and increase the RTP of this slot machine.

Wait, what? That’s right the RTP starts with a low 95.5% but if you get past all the levels, it goes to a super high 97.75% – which is probably one of the highest we’ve ever seen next to Quickspin’s Pirates Charm slot.

If you wanted the most you can get from a bonus slot, you can’t get more creative than this Rabcat video slot.

Rise of Merlin – Play’n GO

You know how we said we wouldn’t have the Book of Ra Deluxe on this list? Well, we didn’t lie, but we weren’t totally honest either.

A list of the best slots with bonus features would not be complete if you didn’t have a game that has expanding scatter symbols. And Rise of Merlin is a good homage, PLUS it’s got a great theme.

A young Merlin is learning all about the world of wizards craft, with dragons and magic potions all set against a beautiful grand hall full of mystery.

The Rise of Merlin slot has 5 reels and 10 payline, where the wild act like the scatter. 3 will trigger 10 free spins where one symbol will be picked to pay like a scatter and expand.

It’s one of the best big win slot feature out there, and with a low minimum bet of 0.10 a spin, everyone can try and aim to catch that 5,000 times your bet.

Viking Runecraft – Play’n GO

You can’t talk about slot bonus features, without mentioning grid slots, cluster pays or avalanching reels. Well, this Viking Runecraft slot game has them all.

This grid slot sits on a 7×7 grid of symbols, where symbols pay when they touch horizontally or vertically in clusters of 5 or more. When you do win, those symbols explode and disappear and more come tumbling down from above in an avalanche of wins.

This is the heart of this Viking Runecraft mobile slot, but it then has so much more to offer. You have 10,000 levels to conquer, and each time you move up a level one of the four gods from Viking Mythology will show up to give you a special feature.

You have free spins bonuses, 4 in-game random features that are charged up on wins, and instant win jackpots. It’s a huge, fun, volatile slot.

Dragon’s Fire Megaways – Red Tiger Gaming

We couldn’t have a video slot with bonus feature list without having one of the Megaways slots. Because you just can’t.

Megaways machines are here to stay and they’ve proven to be so popular, everyone has a version. But we love this addition to the Red Tiger slots collection, because of the way the multipliers work (a feature we still haven’t commented on in this post).

As we write in our Dragon’s Fire Megaways slot review, this has the usual set up: 7 reels, where every row on each reel changes, meaning you can have as few as 729 ways to win all the way up to 117,649 ways to win on any spin.

But what makes this special is that on every win, the multiplier will increase – including in the base game, which is more than you’ll find in Bonanza or Extra Chilli by Big Time Gaming.

During the free spins, the multiplier never decreases, meaning you can get up to 50x multiplier on all wins in the free spins with a whole load of luck.

It’s exciting, it’s certainly wonderful, and it gets you the kind of wins that is hard to beat.
