of tools—such as advanced graphics, animation, and sound effects—help elevate the gaming experience. But just as important is the development of gameplay itself. That means crafting fresh narratives, introducing new events, and adding elements that players haven’t encountered before.
This approach is especially common in the world of video slots. New slot machines regularly feature special symbols with unique mechanics. Among the most dynamic of these are Wild symbols, which often come with unpredictable and exciting properties.
Today, we’ll take a closer look at how Wild symbols work in modern slot machines.
The role of the Wild symbol in the overall structure of slot machines
No matter how much players enjoy a particular slot machine, playing the same game for too long can become repetitive. That’s why many players switch between three or four different slots in a single session. Game developers understand this need for variety and continue to expand their portfolios with diverse titles to keep things fresh.
Even studios known for a distinct visual style release a wide range of games to appeal to different preferences. After all, every player has their own favourite themes, reel layouts, bonus mechanics, and gameplay elements. Bonus symbols, especially Wilds, play a crucial role in enhancing that experience.
Before diving deeper into how Wilds function, it helps to look at what makes up a slot machine. Every slot includes:
- A specific number of reels
- A set number of paylines
- Symbols that form winning combinations
- Bonus rounds or bonus features
Each of these components can vary, creating different gameplay experiences. More reels can mean a larger variety of symbols on screen. More paylines increase the number of possible combinations. Symbols and bonus features, meanwhile, introduce unique mechanics that add depth and unpredictability.

Wild symbols stand out as elements that often bring immediate or future benefits. When a Wild lands, it may trigger a sequence of events that increases a player's chance of winning—either by substituting for other symbols, activating bonus features, or unlocking enhanced payouts.
All functions of Wild symbols
Wild symbols—often simply called "wilds"—are a key element in both modern and classic slot machines. The term itself comes from English and refers to a versatile icon that plays a special role in the game. While the word appears in other gaming contexts, here it has a specific function and significance.
Their main role is to substitute for standard symbols. In a traditional slot, wins are formed by matching icons along predefined paylines. When one of these special symbols lands in place of a missing icon in an otherwise winning line, it completes the combination, making it valid. This increases the chances of payouts, even when the required symbols don’t appear in perfect order. In many cases, such combinations are also treated as one symbol longer, potentially boosting the reward.
Another notable feature is the ability to multiply winnings. It’s common to find games where a combination including one of these special icons comes with a multiplier—often x2 or more. This means that the payout can be doubled or even tripled. This mechanic was especially popular in titles released during the 2000s and 2010s.
Newer slot releases may not always offer multipliers, but often introduce creative twists. Some of these symbols expand across reels, stay sticky for several spins, or trigger cascading wins. These mechanics help keep gameplay dynamic and engaging.
In some slots, wilds can even help trigger bonus games or features, although this role is more commonly assigned to scatter or bonus symbols. Still, when wilds do act as a key to bonus rounds, they often contribute to some of the most exciting moments in the game.
Perhaps most rewarding of all is when wild symbols form their own winning combinations. In many slots, if multiple wilds line up on a payline, they award one of the highest possible payouts. You’ll usually see these combinations highlighted in the paytable. Some exceptions apply—for example, in games where wilds don’t appear on the first reel, they may not form standalone combinations. However, developers often balance this limitation with enhanced wild features during bonus rounds.
Speaking of bonuses, wilds often become even more powerful during free spins or other special features. A wild may carry a higher multiplier, expand across reels, or become sticky (remaining in place for several spins), significantly increasing the player’s chances of a big win.
Special wild symbols
Today’s slot developers continue to make wild symbols even more exciting by combining them with powerful bonus features. These enhancements not only increase the chances of winning but also keep gameplay fresh and engaging. Some of the most common and innovative wild features include:
- Increasing multiplier
This feature is often found in slots with cascading wins or repeated combinations. When a wild symbol takes part in multiple consecutive wins, its multiplier grows. For example, the first win might apply a x2 multiplier, the next x3, and so on—boosting your payout with each successful combination. - Stacked wild symbols
Stacked wilds appear in vertical blocks, often covering 2 or more positions on a single reel. This design allows for bigger and more frequent wins, as entire reels can be filled with wilds, significantly increasing the number of potential combinations. - Expanding wilds
These wilds grow to cover more positions on the reel, either upward, downward, or both. Once a wild appears, it expands to occupy adjacent sections, helping create more winning combinations by covering an entire reel or multiple symbols. - Sticky wilds
Sticky wilds stay locked in place for several spins, giving players more chances to land winning combinations. They are often triggered during free spins or bonus rounds and can lead to long chains of wins if several sticky wilds remain active. - Floating wilds
Unlike sticky wilds, floating wilds move around the screen. They stay in play for several spins but change position after each one, potentially affecting different paylines and combinations every time. - Gravity-based wilds
Found in some modern slots with gravity-style mechanics, these wilds don’t disappear immediately after a win. Instead, they fall down one position with each spin, remaining active until they are no longer part of a winning sequence. This mechanic allows wilds to contribute to multiple wins in a single session. - Extra wilds
In certain situations, games may randomly add additional wild symbols to the reels. This can happen as part of a special feature or during specific bonus rounds, instantly boosting the player's chances of hitting a big win. - Guaranteed wilds
During free spins or respins, some slots offer a set number of guaranteed wilds. For example, a feature might promise that every spin will include at least two wilds, increasing the likelihood of forming valuable combinations across multiple spins.
The best slot machines with wilds
Last but not least, let's talk about some well-known slot games that have added even more fun to these special symbols. These titles show how they can be used to make gameplay more engaging and increase the chances of a win.
Starburst by NetEnt is a classic example. When one of these icons lands on the reels, it expands to cover the entire column from top to bottom. The player then gets a free respin, and the expanded symbol stays locked in place for that spin. This creates more chances for combinations and bigger payouts.
Queen of Hearts by Novomatic is another slot that offers big potential. A player can win up to 10,000 times their line bet by landing a full line of substitutes. During the free spins feature, extra ones appear more often, giving players more opportunities to win without placing additional bets.
Dolphin's Pearl Deluxe, developed by Octopus, sticks to a more traditional mechanic. Here, if one of these symbols completes a winning line, the payout from that line is doubled. That x2 boost adds value to each completed combination.
In Elements by NetEnt, different bonus rounds feature various types of these symbols. Some move around the grid, while others remain fixed for several spins. The game’s dynamic structure and varied features make it engaging over longer sessions.
Another recent release, Cygnus by ELK Studios, includes multipliers tied to these icons. These bonuses can increase during the bonus rounds and continue stacking up if the same symbol remains part of winning combinations, leading to even higher rewards.
All of these games show that these versatile symbols can do far more than just substitute for others. They can expand, move, grow in value, or appear in larger numbers during bonus features. Thanks to clever game design and advanced mechanics, they’ve become one of the most exciting elements in today’s most popular slot machines.
