How can wilds help us when we play online slots?

We love our slots here at but if you’re a beginner or want to brush up on your knowledge of them, we take a look at wild symbols and how they help us win big when playing. Let’s take a look at the different kind of wild symbols you will come across in slots and in our reviews:

Wild symbols (or wilds) act like a joker in slots. For example, if you were to take the classic Cleopatra from IGT, the Cleopatra logo is the wild symbol. If you were to get a scarab beetle symbol on reels 1 and 3 with the wild on reel 2, it would act like a scarab beetle to give you a winning combination.

Basically, wilds replace other symbols to give you the best winning combination possible. However, there are many types of wild symbols which often appear in the bonus/free spins features – here’s some of the main ones you’ll come across:

Wild/Stacked Reels

A wild reel is a reel made up entirely of wilds – it’s also referred to as stacked wilds too as they are stacked to fully occupy a reel. If you take IGT’s Icy Wilds, you will benefit from a wild reel when a full stack of any of the animal symbols appears during a spin – in the next spin, that reel is fully wild.

Sticky/Locked/Frozen Wilds

Sticky wilds refers to wild symbols that remain sticky on the reels – they can also be known as frozen or locked wilds. If you take ELK Studios’ Sam on the Beach, you can benefit from random sticky wilds when Electric Sam lands on the reels. In Playtech’s Superman The Movie, Superman wilds remain locked in place for the duration of the Save The Day Free Games feature.

Multiplier Wilds/Wild Multipliers

Wild multipliers means that wild symbols carry a multiplier value – if you take WMS’ Raging Rhino, it benefits from 2x and 3x multipliers in the Free Spins feature. If you get a winning combination with the tree wild, the wilds change into 2x or 3x multipliers to enhance your win.

Expanding Wilds

An expanding wild is a wild that expands to take over the whole reel – slots like NetEnt’s Starburst offer you the possibility of getting up to 3 expanding wilds on each spin! In WMS’ Black Knight II, you will get a locked, expanded wild in the feature – when the knight arrives (the wild), it expands to take over the reel and remains in place for the duration of the feature. There’s up to 3 to be won in the feature which can lead to huge wins!

Spreading/Walking Wilds

Spreading wilds, also known as walking wilds, are wild symbols that spread to the left or to the right. If you look at NetEnt’s Wild Wild West: The Great Train Heist, spreading wilds turns 1 adjacent or diagonal symbol into an extra wild symbol – it can also be known as contagious wilds. In ELK Studios’ Wild Toro, the bull goes wild and charges towards the matador in the Toro Walking Wilds feature leaving a trail of wilds for the respin.

In NetEnt’s Jack and the Beanstalk, you will get a free re-spin when a wild appears – the wild will also move 1 reel to the left with another re-spin to follow. These continue until the wilds no longer appear on the reels – in this game, it’s referred to as Walking Wilds.

Random/Extra Wilds

Random wilds means that wild symbols are randomly added to the reels – if you take Playtech’s Age of the Gods Fate Sisters, you will benefit from 3 random wilds on every free spin in the Clotho’s Temple Free Games feature. In Playtech’s Age of the Gods, you will get up to 5 random wilds on every free spin on the Poseidon Free Games feature!

Colossal/Giant Wilds

Colossal wilds means giant wilds that appear on the reels – for example, in NetEnt’s Spiñata Grande, a 3×3 colossal wild symbol appears on reels 2, 3 and 4 for colossal wins! In some WMS slots like Giant’s Gold, stacked wilds appear and transfer to the other reel set. In Playtech’s RoboCop, you will get giant 3×3 wilds on each free spin in the Robot Attack Free Games feature.

Duplicating/Replicating Wilds

Finally, we have duplicating wilds – the best way to explain it is using Play ‘N Go’s Grim Muerto where 1 reel is highlighted before each spin – if the guitar wilds lands, it will duplicate to take over the entire reel.

As you can see, there are many types of wild symbols – each software provider has a different name/term for them but the ones listed above will cover most, if not all, of them. All you need now is good luck!
