The wild is the most familiar special symbol in pokies. Its basic job is simple: it substitutes for other symbols to help complete winning combinations. Yet over the years, studios have turned the humble wild into one of the most varied tools in game design. Some wilds stay put, some walk across the reels, some multiply wins and some cover entire reels in a single landing.
Game resources such as https://thepokies-aud.co list the wild types used in individual titles, and once you understand the main variations, you can predict a lot about how a game will behave. This article explains the most common kinds of wild, what each one does to the rhythm of play and how to read the rules so you know exactly what to expect.
The Standard Wild
The standard wild substitutes for all regular symbols, usually excluding scatters and bonus symbols. It lands like any other symbol and helps complete wins on paylines or ways. In some games, wilds also pay on their own when several line up, often matching or exceeding the top regular symbol.
Even the standard wild varies between games. It may appear on every reel or only on certain reels, commonly reels two to four. Reel restrictions make a big difference, because a wild that cannot land on the first reel can never start a winning combination.
Expanding Wilds
An expanding wild grows to fill the entire reel when it lands. This turns one substitute into three, four or more, depending on the number of rows. Expanding wilds often appear on specific reels and can create several wins at once. Some games add a respin when an expanding wild lands, holding the wild reel in place while the others spin again.
Sticky Wilds
Sticky wilds stay in position for several spins, or for the remainder of a free spins round. They are most common in features, where they gradually accumulate and increase the chance of wins as the round progresses. In the base game, sticky wilds may last for a fixed number of spins before disappearing.
Walking and Shifting Wilds
Walking wilds move one position, usually to the left, on each spin until they leave the grid. Each move typically comes with a free respin, so a walking wild landing on the far right reel can produce a sequence of respins. Shifting wilds move in other patterns, sometimes randomly, creating unpredictability.
Multiplier Wilds
Multiplier wilds apply a multiplier, such as 2x or 3x, to any win they help create. When several multiplier wilds contribute to the same win, the multipliers may add together or multiply each other, depending on the game. Multiplicative stacking can produce very large results, which is why multiplier wilds are often associated with higher volatility.
Stacked and Colossal Wilds
Stacked wilds appear in tall groups on a reel, sometimes covering the whole reel. Colossal wilds occupy a block of positions across several reels and rows, such as a 2×2 or 3×3 area. Both increase the number of positions covered by wilds in a single spin.
| Wild type | What it does | Effect on gameplay | Volatility tendency |
|---|---|---|---|
| Standard | Substitutes for regular symbols | Steady support for wins | Neutral |
| Expanding | Fills the entire reel | Multiple simultaneous wins | Medium |
| Sticky | Stays in place for several spins | Builds value over time | Medium to high |
| Walking | Moves each spin, often with respins | Chains of follow-up spins | Medium |
| Multiplier | Multiplies wins it contributes to | Occasional large spikes | High |
| Stacked / colossal | Covers several positions at once | Big coverage on single spins | Medium to high |
| Random wilds | Added to the grid at random | Unpredictable boosts | Varies |
Random and Feature-Triggered Wilds
Many games add wilds at random during base play or free spins. A character might appear and throw wilds onto the reels, or a feature might convert certain symbols into wilds. These random wild features add excitement to otherwise quiet spins, and their frequency is accounted for in the game’s overall RTP.
How Wild Design Shapes Volatility
The type of wild a game uses strongly influences its volatility. Games built around standard or expanding wilds often feel steadier. Games that rely on multiplier wilds or sticky wilds during free spins tend to concentrate value in rare moments, producing bigger swings. When comparing games, the wild mechanics are one of the clearest signs of how a game will feel.
Reading the Wild Rules
Before playing, check the paytable for the following details:
- Which reels the wild can appear on
- Which symbols it substitutes for and which it does not
- Whether the wild pays on its own
- Whether multipliers add or multiply when combined
- Whether wilds behave differently in free spins than in the base game
These details can change the game’s character dramatically, and they are easy to overlook if you skip the rules.
Wilds and Player Perception
Wilds are visually prominent and often animated, which makes them feel especially significant. A wild landing near a potential win attracts attention even when it does not complete a combination. As with any feature, the excitement of seeing a wild should not be confused with a change in odds. Every outcome is determined by the random number generator when the spin begins.
Many of these wild types first appeared on venue cabinets before moving online, and Australian club players will recognise expanding and stacked wilds in particular from long-running machine series.
Final Thoughts
Wild symbols have evolved from simple substitutes into a whole family of mechanics, each with its own effect on how a game plays. Understanding the differences between expanding, sticky, walking, multiplier and stacked wilds helps you choose games that suit your style and read their rules with confidence.
