Slot Features Explained: Wilds, Scatters, Multipliers and More
Modern online slots have come a long way from simple reels and matching symbols. Today's slot games can include a wide variety of features, from Wild and Scatter symbols to multipliers, free spins, bonus rounds, cascading reels and jackpots.
But what do all these slot features actually mean?
If you've ever opened an online slot and wondered what a particular symbol or feature does, you're not alone. While the basic idea of a slot game can be easy to understand, the individual mechanics can vary considerably from one game to another.
Understanding the most common slot features is a useful way to see what makes different online slots unique. Here's a closer look at some of the features you'll encounter in modern slot games.
What Are Slot Features?
Slot features are mechanics that add something to the standard reel gameplay of an online slot.
Some can affect how winning combinations are formed, while others can trigger free spins, bonus rounds, multipliers or changes to the reels. Certain features may only appear under specific conditions, while others can be active during the base game.
There is no universal set of features that every slot must contain. Developers can combine familiar mechanics in different ways, which is one reason online slots can offer such varied experiences.
What Are Wild Symbols?
Wild symbols are among the most common features in online slots.
A Wild can often substitute for another symbol when forming a winning combination. However, not every Wild works in exactly the same way.
Some Wilds can expand across the reels, while others may be stacked, move between positions, appear only during free spins, or have additional functions connected to other features.
The role of a Wild is therefore determined by the individual game's rules. The paytable or information screen will explain which symbols a Wild can replace and whether it has any additional functions.
What Are Scatter Symbols?
Scatter symbols are another familiar feature in modern slot games.
Unlike standard symbols, Scatter symbols often have a special function that isn't dependent on appearing along a conventional payline. Depending on the slot, landing a certain number of Scatters can trigger free spins, a bonus round or another feature.
The number of Scatter symbols required and what they activate varies between games, so it's worth checking the individual slot's rules before playing.
What Are Multipliers in Online Slots?
A multiplier increases the value of a qualifying win by a specified amount.
For example, a 2x multiplier represents twice the relevant win, while a 5x multiplier represents five times the relevant win, subject to the game's rules.
Multipliers can be incorporated into online slots in many different ways. They may be attached to particular symbols, appear during bonus rounds, increase during a feature or be activated under specific conditions.
This flexibility makes multipliers one of the most recognisable features in modern slot games.
What Are Free Spins?
Free spins are a feature found across many online slots.
They generally involve a set number of spins taking place within a dedicated feature without a separate stake being required for each individual spin. However, the exact rules differ from game to game.
Free spins can also introduce additional mechanics. A slot might add multipliers, special Wilds, expanding symbols or other features while the free spins are active.
As a result, a free spins round can sometimes feel quite different from the game's standard base gameplay.
What Are Bonus Rounds?
Bonus rounds are special sections of an online slot that operate differently from the regular reel game.
There isn't one standard type of bonus round. Depending on the slot, it might involve selecting symbols, triggering a separate reel configuration, collecting values, completing a sequence, or activating another set of mechanics.
Some bonus rounds are triggered by Scatter symbols, while others rely on specific combinations or features.
The variety of bonus rounds is part of what gives individual slot games their own character.
What Are Cascading Reels?
Cascading reels, also known as tumbling reels, change what happens after certain winning combinations.
Instead of the reels simply resetting after a win, qualifying symbols can disappear and new symbols can fall into the empty positions. This can create another combination within the same sequence.
Cascading reels are often combined with other features, such as multipliers or free spins, creating additional layers to the game's mechanics.
What Are Expanding Symbols?
Some online slots include expanding symbols that can cover multiple reel positions.
An expanding symbol may grow vertically or across part of the reel when a particular condition is met. In some games, expanding symbols are connected to free spins or bonus features.
The exact behaviour depends entirely on the game's design, making the information section or paytable the best place to check how a particular expanding symbol works.
What Are Stacked Symbols?
Stacked symbols are symbols that appear in several consecutive positions on a reel.
A stack can make multiple instances of the same symbol appear together, depending on the game's reel design. Some slots use stacked symbols as part of their regular gameplay, while others introduce them during particular features.
Stacked symbols can also be combined with Wilds, expanding symbols and cascading mechanics.
How Do Jackpot Features Work?
Some online slots include jackpot features alongside their standard gameplay.
A slot may have a fixed jackpot, while another may use a progressive jackpot that changes according to its own rules. Jackpots can also be connected to particular combinations, bonus features or dedicated jackpot rounds.
There is no single way that a jackpot feature works across all online slots, so the game's rules should always explain how its jackpot is awarded.
What Are Collection Features?
Collection mechanics are another feature found in some modern slot games.
These features involve collecting particular symbols, values or items during gameplay. Reaching a specified condition may activate another feature, such as a bonus round or free spins.
Collection mechanics can give a slot an additional sense of progression, with different spins contributing towards a larger feature.
How Do Slot Features Work Together?
One of the most interesting aspects of modern online slots is that features don't necessarily operate independently.
A game might combine Wild symbols with cascading reels, introduce multipliers during free spins, or use Scatter symbols to trigger a bonus round containing an entirely different mechanic.
These combinations allow developers to create distinctive slot games while still using concepts that players can recognise.
It's also why two online slots can both contain Wilds, Scatters and free spins yet feel completely different.
Why Are Slot Features So Important?
Slot features give developers a way to create variety within a familiar format.
The basic structure of reels and symbols can remain recognisable while features change how those reels behave. Themes can also be connected directly to the mechanics, giving a slot game a stronger sense of identity.
For players exploring online slots, features can also be a useful way of comparing games. One slot might centre around cascading reels, another around multipliers, while another could focus heavily on bonus rounds or jackpot mechanics.
Where Can You Find a Slot's Features?
The easiest way to understand an online slot is to check its paytable or information section.
This should explain the game's symbols, winning combinations and special features. It can also provide important information about how Wilds, Scatters, free spins, bonus rounds, multipliers and jackpots work within that particular game.
This is especially important because the same feature can behave differently from one slot to another.
Final Thoughts
Wilds, Scatters, multipliers, free spins, bonus rounds, cascading reels, expanding symbols, jackpots and collection mechanics are just some of the features found in modern online slots.
While the names of these features may be familiar, their functions can vary considerably between games. Developers can combine them in different ways to create slot games with their own themes, mechanics and identities.
Understanding these common slot features makes it easier to explore the world of online slots and recognise what makes each game different.
The next time you open a new slot game, take a look at its paytable and see which features are included. You might find that the reels are only the beginning of what the game has been designed to offer.
