Online slots are an incredibly popular choice among players at LeoVegas UK – we have over 2,000 different titles for players to browse through! These are made up of familiar genres, like fishing, car racing, Irish legends, and many other branded and seasonal themes. Most slots share the same gameplay mechanic, so they are easy to learn, and beginners will soon be able to take advantage of all the special features.

From free spins to scatters and wilds that can take the place of other symbols, there are many ways that basic online slot games are enhanced and improved with different features. One of the most innovative is the stacked wilds; these are special symbols that expand across the screen and can take over an entire reel when they appear!

What are stacked wilds?

Stacked wilds are similar to standard wild symbols but there are some crucial differences. They often arrive in clusters of two, three, four, or even five icons. This is in contrast to standard wilds that tend to arrive alone or in a pair and occupy just one or two spots on the reels. In some slot games, stacked wilds will only ever appear on one of the reels, so players always know where to look for them. In others, they can pop up on every reel at any point in the game so that they can take players by surprise!

Stacked wilds also vary in terms of what triggers their appearance. Some slot games only feature stacked wilds during a bonus round. The stacked wilds can often be combined with other specials like multipliers to potentially boost a win when playing these titles.

How do stacked wilds work?

Anyone who has ever played a slot game that includes expanding wilds will be familiar with the concept of stacked wilds. They affect the game similarly, but the main difference is that with stacked wilds, a single wild drops onto the reel as the feature begins, and it grows to take up many spots. However, stacked wilds are still, basically, wild symbols. They are designed to help a player complete a combination that results in a payline by replacing other symbols on the reels.

More experienced players go for games that include a stacked wild element because they can offer a higher winning potential than standard wilds. Stacked wilds expand across the grid to create many potential wins. In contrast, a single wild will usually only cover one spot on the reel.

Choosing slots with stacked wilds

Those who are looking for slots with stacked wilds can go for titles they know have multiple paylines because that's often where they can be found. They can fill entire reels when they appear in the game and stack up on top of each other. This feature can be helpful in a game with numerous paylines!

Depending on the game's rules, a stacked wild could grow to take up the whole reel it lands on, or it could just occupy the top or lower area of the reel. Look at how stacked wilds work in a particular game before playing in the paytable area. When coupled with many paylines, stacked wilds can create many potential wins.

Stacked wilds slot games

Those who want to see how slots with stacked wilds can play out, here are a few games they could try.

Double Dragons

Double Dragons is a myths and legends-themed slot with gorgeous graphics and plenty of unique features. The stacked wilds can take up between seven and 28 symbols and are triggered by the Double Dragon's special feature. Players will need a run of consecutive wins to get to this round.

Wild Mantra

Wild Mantra has a golden stacked wild that works in two ways: a soothing slot with a zen-inspired theme and a backdrop of lush mountain scenery. It can act as a substitute for other symbols, like a regular wild, or be stacked over the reels to form more possible wins.

Gold Mine Stacks

Set in the Wild West, Gold Mine Stacks is a mining slot that transports players deep underground to hunt for a seam of glittering treasure. The full wild stack respin feature is triggered by landing enough wild stacks to fill an entire reel. Once that happens, a bonus round begins with the final stack becoming sticky and the other reels respinning. Landing another wild stack at this point triggers even more respins until the last of the stacks land.
