What are Stacked Wilds?

You must have seen them, right? Stacked Wilds, I mean? But what do they do exactly? Welcome to the Wombat Slot University! Take a seat.

Stacked wilds are a popular feature in online slot games that can enhance the excitement and winning potential of the gameplay. These special symbols are designed to increase your chances of forming winning combinations and securing a win. In this explanation, I will go into the mechanics of stacked wilds, how they function in online slots, and their impact on the overall gameplay.

To understand stacked wilds, let’s first define what a wild symbol is. In slot games, a wild symbol will substitute for other regular symbols, helping you to make up winning combinations. For example, if you have two identical symbols on a pay-line, and a wild symbol appears next to them, it can act as the missing third matching symbol to trigger a win.

Let’s Imagine

Now, imagine a tower or block of wilds that lands in a vertical stack, covering multiple positions on a reel. Rather than appearing as a single symbol, stacked wilds occupy an entire reel or several adjacent positions on a reel, making them more powerful and more effective at making up winning combinations on the reel set.

When a stacked wild appears on the reels, it increases your chances of forming winning combinations. Since the wild symbol can substitute for other symbols, having a stacked wild on a reel means that multiple winning combinations can be created simultaneously. This can lead to decent payouts, especially when stacked wilds appear on multiple reels simultaneously.

The potential for stacked wilds also adds an element of anticipation and excitement to the gameplay. As the reels spin, players await the appearance of stacked wilds, hoping that they will land in strategic positions to generate big wins. The sight of a full reel or multiple reels covered in stacked wilds can be a real buzz, and is often the key to higher wins.

Stacked Wilds Plus

In some online slot games, stacked wilds may come with additional features to further enhance the action. For instance, stacked wilds may come with multipliers, which boost the value of any winning combos they contribute to. This means that not only will the stacked wilds help create more winning lines, but they will also supercharge the associated payouts.

It’s important to understand that stacked wilds are found in specific slots and can vary in their behaviour from game to game. Stacked wilds may only appear during certain bonus rounds or free spins, adding an extra layer of excitement during the special features. But then, of course, you have got to get into the bonus first.

Make sure you understand the rules and the pay table of the slot game you’re playing for a clear understanding of how the stacked wilds function.


Stacked Wilds are an exciting feature to look out for in online slot games that offer boosted opportunities to win. By appearing as vertical stacks of wild symbols, they increase the possibilities of forming winning combinations and lead to some good runs.

Their appearance on the reels all adds to the thrill of the game, and in some cases, they may be linked to multipliers or exclusive bonus features. Remember that each game will have its own rules regarding stacked wilds, so familiarize yourself with the specifics before firing up the game.
