Special variants like sticky, expanding, or stacked wilds create extra winning opportunities. Sticky wilds stay in place, expanding wilds stretch across the reel, and stacked wilds cover multiple positions on a reel.

What Are Wilds in Slots? A Quick Look at 10 Types
Wild symbol variations can significantly impact gameplay. Here’s a breakdown of the 10 most important types of wild symbols at a glance:
These wilds spread across the entire reel and increase the number of paylines. A well-known example is Starburst by NetEnt. In this slot, the wild symbols expand across the entire reel and also trigger a re-spin.
Sticky wilds stay fixed in the same position for several spins, making them especially valuable during bonus rounds. A great example is Dead or Alive 2 by NetEnt, where sticky wilds hold their positions throughout the bonus rounds.
Walking wilds shift to adjacent positions after each spin, creating new opportunities to win with every move. A classic example is Jack and the Beanstalk by NetEnt. In this game, walking wilds move one position to the left after each spin, continuing until they exit the playing field.
These wilds jump from position to position until they disappear from the playing field. A good example of shifting wilds is the slot Divine Forest from Spinomenal. Here, wild symbols move during the spins and create new chances of winning.
Stacked wilds appear in groups, often covering entire reels, and can lead to substantial wins. A great example is White Rabbit by Big Time Gaming, where stacked wilds are used to create the largest possible winning combinations.
These wild symbols appear randomly in any position on the reels during a spin, providing moments of surprise and are often integrated into bonus rounds. Example slot: Gonzo's Quest Megaways by NetEnt.
These wilds not only substitute for other symbols, but also multiply the winnings, often by x2, x3 or even more. They appear in base games or bonus rounds. Example slot: Immortal Romance by Microgaming.
Overlay wilds appear on top of existing symbols without replacing them. They can trigger additional features such as multipliers or bonus rounds. Example slot: Ghostbusters Plus from IGT.
These wilds “wander” between the reels and appear on another reel after a spin, creating new winning opportunities. In contrast to Walking Wilds, this feature is often used in conjunction with bonus rounds, moves between the reels and does not follow any particular order. Example slot: Twin Spin by NetEnt.
Expiring wilds are temporarily active and disappear after a certain number of spins. They are often used in bonus rounds. Example slot: Jammin' Jars by Push Gaming.
Advantages and Disadvantages of Wilds in Slots

- Diverse functions: Different wilds, such as expanding wilds that stretch across the reel or sticky wilds that remain in place, create new ways to win.

- High expectations: The rarity of wild symbols can lead to long waits, which may frustrate players.
