In a competitive world such as the online slots casino industry, developers are constantly looking for new ways to import innovation into their slot games. Almost every theme from fantasy worlds to everyday events have been covered in terms of graphics and animation. This is why developers are now looking into creating more exciting gameplay with better incentives and more bonus features.

This blog post will primarily be talking about the Stacked Wild feature - a relatively newer mechanic, but something that has been incorporated into over hundreds of slot games since its original release.

What Are Stacked Wilds?

A stacked wild is essentially a wild symbol that covers an entire reel when it drops onto the makeshift slots on the screen. A stacked wild is in fact similar to a wild symbol, however, instead of replacing one particular symbol on a reel, a stacked wild replaces every symbol on it.

Understandably enough, the chance of triggering a winning combination using a stacked wild is a lot greater than its regular counterpart. These symbols can appear on any reel, but are normally seen on reels 2, 3, 4, and 5 in slot games with an average of 5 reels.

Another important factor to consider is that stacked wilds are usually seen in games with either high or very high variance. This isn’t to dissuade low-rollers from exploring the excitement of a game with stacked wilds, but to understand the dynamics of a game with them.

Who Created the Stacked Wilds Feature?

There isn’t much information on which developer actually came up with the idea of a stacked wild, but it is fair to say that certain games popularized the mechanic more than others.

For example; IGT’s Western Belles uk slot games is a great example of an online slot game that uses stacked wilds. When Western Belles is played in a maximum of 40 lines, one reel in the game is guaranteed to generate a stacked wild symbol.

Some games feature stacked wilds in the base game while others might feature the mechanic in either the free spins round, mini-game round, and other bonus rounds.

What are Normal Wild Symbols?

A wild symbol is a symbol that acts as a replacement to any other symbol in the game or at least has the potential to replace most of them. These symbols have special characters or logos on them and are not a part of the slot’s usual symbols; the low-paying and the high-paying ones.

Think of a wild symbol as a joker in a pack of cards; the joker can be used to substitute for any other card in the deck. However, there are certain slot games wherein the wild symbol can only work so far. There’ll still be some symbols that the wild symbol can not substitute for. These symbols are usually bonus symbols such as scatters or money symbols.

In a typical, three-reel slot game with one payline, the wild symbol is definitely going to be there. If a player lands two matching symbols and a wild symbol, they can generate a winning combination because the wild symbol can act as the symbol they would’ve needed to win.

Developers are using animations, video footage and sound effects to signify wilds, and with five or seven reels and multiple paylines, there are plenty of wins to be generated when a wild symbol hits the reels.

How Does a Stacked Wild Work?

Stacked wilds work in more or less the same way as expanding wilds. Stacked wilds, however, have a single symbol that falls onto the reels which then expands to fill designated spaces around it. A stacked wild might expand to fill up an entire reel or just to fill the top or bottom sections of it.

Every game has different rules attached to stacked wild symbols. These rules can be accessed in the instruction panel of the game or are displayed on the paytable. It is important to understand that stacked wilds work in different capacities in different games.

However, a general rule is that stacked wilds appear as several wild symbols that are stacked on top of one another. These stacked symbols then cover all of the reel or parts of it.

Recognizing a Stacked Wild Symbol

If a slot features a stacked wild symbol, it would be pretty easy to spot. Gameplays that incorporate stacked wilds usually have them placed on the same reel and feature wild symbols making their way onto other reels. This wild symbol then moves around filling the reel.

These symbols typically stand out from the rest of the game's graphics, having a coloured stripe that follows around them. Other animations include an abrupt expansion of the base wilds. Games even feature wild slots that simultaneously take up multiple rows on the same grid layout, usually showing a triumphant move whenever a player makes one during any round of the game.

Wilds will not generally be found in classic slots and will be found almost always in the best video slots online.


Mini-games are bonus games apart from the base game of a slot. These mini-games feature the theme in a more animated way. To simplify, a slot with a Wild West theme would have a one on one shootout in its bonus games. Basically, a mini-game is a part of a game that’s made to be a whole lot more exciting. Think of it as a reward for excelling in the base game.

As part of your reward, you’ll get a chance to access bonus features that include stacked wilds. For instance, while playing the game Dolphin Quest, players get to play a mini-game featuring a 3-reel slot, giving them a chance to cash out 100 to 5000 coins.

Free Spins Rounds

The Free Spins Round of any slot game has its own perks (as the name implies) and it goes a step further by incorporating other features and bonuses. This includes the stacked wild feature.

Free Spins Rounds are triggered when a particular number of scatters appear on the reels in a traditionally played slot game. Once the symbols appear, a player is redirected to the Free Spins Round.

Here they have the chance to play with free spins and added bonuses. Mostly, the bonus is a random multiplier or a progressive jackpot. With both of these, a stacked wild is a great feature to have to make the gameplay all the more exciting.
