What is it that makes us return to our favourite slots? Some might say it’s the game’s look and feel, or its volatility, but we think it’s slots bonus features that keep us coming back for more. They add some real action to a game and they can give out some big wins too.

How do you know which games are the best to try, though? Well, Frankie and the team have done some digging around and found six online slots with bonus features we think are the best in town.

Jack and the Beanstalk by NetEnt

The character in this legendary slot may be small but don’t let that fool you, because this game boasts a giant of an online slots bonus feature. 

If you land 3 or more of the Treasure Chest symbols you will activate the Free Spins feature and get 10 free spins, while a further 5 free spins will be heading your way if you land a further 3 or more chests. And if that’s not enough, all Wild wins benefit from a 3x Multiplier too!

The Treasure Collection sits within the Free Spins game, where the aim is to collect more and more keys for extra Wilds, Stacked Wilds and Re-spins. There’s also a potential max win of 1,500x your stake in the Free Spins feature.

Rise of Merlin by Play’n GO

What better way to conjure up a slots bonus feature than with the legendary wizard himself?

This slot has a pretty exciting Free Spins feature which can be triggered by landing 3 or more Crystal Ball Scatters for 8 free spins. At the beginning of the feature, one of the symbols is randomly selected to be the special expanding symbol, and when the Free Spins feature kicks in, this symbol will expand to cover the reels.

If you land 3 or more Scatters during the feature then this retriggers the feature for another expanding symbol and 8 extra free spins too. With a max win potential of up to 5,000x your stake, it might just be worth putting on your wizarding cloak.

Game of Thrones by Microgaming 

Just like the hit TV show this game has plenty of action on its reels, and the good news is that you don’t need to be a fan to enjoy this slot game. Its four (yes you read that right, four!) Free Spins features should be enough to make anyone bend the knee!

Land 3 Game of Thrones Scatters to trigger the Free Spins round and get the chance to pledge your allegiance to one of the four Houses of Westeros – each with their own Free Spins feature offering unique Multipliers, Free Spins and Stacked symbols.

Look out for House of Baratheon as it has a max win potential of 20,000x your stake! And, it’s possible to retrigger each of the four Free Spins rounds again too.

Gonzo’s Quest by NetEnt

Gonzo’s Quest was one of the first slots to lose the reels and use the innovative Avalanche feature to power its game with, meaning more chances to win.

Enter the Free Falls feature by landing Free Falls Scatters on reels 1,2 and 3. Scoop 10 Free Falls instantly, while the more Avalanche Falls you get the higher the Multiplier awarded with up to 15x your stake possible and more free spins to be had too.

The action doesn’t stop there though. With a winning combination, the Avalanche Multipliers feature is activated. Multipliers are increased by 1x with every further Avalanche up to 5x.

Legacy of Dead by Play’n GO

With many Egyptian-themed slots out there it can be difficult to decide which one to play. Well look no further than Legacy of Dead, the much anticipated follow up to the legendary Book of Dead.

Trigger the Free Spins feature with 3 or more Scatter symbols to be awarded 10 free spins and up to 200x your stake. An expanding special symbol will also be randomly selected. This symbol can expand to cover the entire reels for more chances to win hidden treasures.

If you progress to landing a further 3 Scatters then it’s possible to retrigger the Free Spins feature many times, for extra free spins and more expanding symbols.

The Dog House by Pragmatic Play

Sink your teeth into this ferocious slot boasting some serious bark and bite, and prepare for a howlin’ good time with an online slots bonus feature promising the chance of big wins.

Look out for the Jewelled Paw symbol, because if you land it on reels 1, 3 and 5 then you’ll activate the Free Spins game, with up to 27 free spins up for grabs.

New reels can also develop in this round with the highest paying symbols appearing Fully Stacked. If you land a Multiplier then this will lock into place until the Free Spins feature is over, with wins potentially being boosted up to 6,750x your stake.
