What Are Slot Machine Symbols?
Slot machine symbols are the icons that appear on the reels of a slot game. They determine how and when you win, based on combinations that align with the game’s paylines and reels. Some trigger payouts, others activate special features — but together, they decide the outcome of every spin.
Classic Slot Machine Symbols & Their Meanings ?
Before video slots took over, mechanical slots ruled the casino floors — and it was these games where classic symbols originated. And with their iconic status and nostalgic appeal, many remain in use today:
- Bells ?
The first ever slot machine was nicknamed the Liberty Bell, and landing three bells on the reels signaled a jackpot win. This symbol lives on in many classic slots today. - Cherries ?
Later iterations of the Liberty Bell introduced a gum-vending attachment to get around gambling prohibition laws at the time, and so fruit symbols like cherries were introduced to the reels. - Bars ?
Allegedly, the bar symbol’s origins lie in the Bell-Fruit Gum company logo, and it’s often high-paying on classic slots. Single, double, or triple bars usually indicate increasing payouts. - Lucky 7s ?
In many cultures, 7 is a symbol of luck — and on classic slots, it’s often tied to the game’s highest wins.
Modern Slot Machine Symbols
While classic symbols are still used in many slot titles — especially games that mimic old mechanical fruities — modern slots have taken creativity to a whole new level. In today’s slots, you’ll find animated, thematic symbols on the reels that are as engaging as they are immersive, from glowing jewels and mythical creatures to branded characters from pop culture.
Take the perpetually popular Rich Wilde and the Book of Dead from Play’n GO. On the reels of this Ancient Egypt slot you’ll find deities like Anubis and Amun, a selection of ancient artefacts — and, of course, the titular explorer himself. In any case, the sky’s the limit when it comes to modern slot symbols.
Types of Slot Machine Symbols
With the complex mechanics and features available in today’s slot games, it helps to break down slot machine symbols by function. Here’s what you’ll encounter on the latest slot games.
Standard Symbols
The base icons that form the foundation of most slot games, all regular symbols unlock wins when you line up three or more across a payline. These are the simplest symbols, often shown as fruit, card suits, or theme-related objects. The payout size is decided by the ratio attached to each specific symbol, ranging from low to medium depending on the game.
Wild Symbols ?
One of the most sought-after symbols, the wild symbol substitutes for other standard symbols to help form winning combinations. Many games attach extra functionality to wilds, like activating bonus rounds once a certain number have appeared on the reels.
Scatter Symbols ?️
The function of scatter symbols varies by game, but they’re named as such because they don’t have to be aligned on a payline to enhance your gameplay. Landing single scatters often results in an instant payout, while multiple might unlock free spins, cascading reels, or even bag you the jackpot prize.
Bonus Symbols ?
A bit like scatters, bonus symbols are the gateway to the real fun — activating bonus rounds, minigames, and jackpot features. Anything goes here, so be sure to check the paytable and game instructions so you know what each symbol does.
Multiplier Symbols ?
Some slots enhance standard symbols with multipliers that increase payout values, like 2x, 3x, 5x or more. Land these as part of a winning payline and you’ll enjoy a bigger prize. They’re often included as part of free spins rounds too, or are attached to mechanics like avalanche reels where a multiplier bar increases each time you trigger a cascade.
Stacked and Expanding Symbols
Stacked and expanding symbols up the ante even more, appearing in groups on a single reel or stretching across multiple symbol positions. They add a more dynamic, unpredictable angle to each spin — just imagine the possible paylines with an expanding wild on your reels!
High-Paying Symbols and How to Identify Them ?
In every slot game, a few symbols stand out as the true money-makers. These high-paying symbols nearly always reflect the slot’s theme, and spotting them early helps you understand what to aim for during your session.
The best way to identify them is to look at the paytable and find the symbols with the biggest multipliers. But you can also figure out which symbols are the most lucrative as they’ll appear less frequently on the reels, or might be animated or styled more prominently than low-value icons.
Themed and Custom Symbols ?
Whether you’re drawn to mythology, movies, or magic, themed slots bring unique symbol categories to life. Here are some popular themes and how their symbols enhance gameplay:
- Egyptian-themed slots – Ankh crosses, scarabs, and pyramids serve as both regular and special symbols.
- Asian-themed slots – Dragons, koi fish, and red envelopes frequently act as wilds, scatters, or bonus triggers.
- Norse-themed slots – Helmets, ravens, and Norse gods often carry high value or activate bonus games.
Understanding Slot Volatility and Its Impact on Symbols
Slot volatility — also known as variance — gives us a sense of how often and how much a slot machine pays out. It plays a crucial role in how symbols on a slot machine behave:
- Low volatility slots offer smaller but more frequent wins. You’ll see more standard and low-paying symbols, and fewer special features.
- Medium volatility slots strike a balance between modest wins and exciting bonuses.
- High volatility slots reward patience, with less frequent payouts that are larger in size. Gameplay is often shaken up by rare symbols like wilds, scatters, or multiplier icons.
When deciding on what to play, think about your budget and the kinds of wins you want to see. Low volatility is better for smaller budgets, as there’s a better chance of landing some payouts before using up your bankroll. For high rollers, high volatility slots may be more entertaining.

?️ Scatter Symbols (Triggering Free Spins & Bonuses)
Scatters are your ticket to free spins and bonus rounds, appearing anywhere on the reels. You often need three or more to trigger their associated features.

This lucky number is a staple across old mechanical slots, and still shows up in many high-paying combinations. - Gold Coins ?
Nothing beats a simple golden coin — and when it comes to slots, these symbols are frequently tied to progressive jackpots. - Golden Star Symbol ⭐
Golden stars often serve as wilds, scatters, or even jackpot triggers in celestial, outerspace, or magical-themed slots.
? Hidden Features: Secret Symbols in Slots
Modern slots are full of surprises — and that’s where hidden or mystery symbols come into play. These aren’t always visible at first glance but can significantly influence the outcomes of your spins. They can include:
- Stacked wilds that appear together, covering multiple rows or reels.
- Expanding symbols that stretch across adjacent spaces.
- Mystery symbols that reveal themselves after a spin.
- Cascading symbols that disappear after a win, with new ones falling into place to create chain reactions.
- Walking wilds that stay on the board, moving across the reels after each spin.
The Evolution of Slot Symbols: From Mechanical to Digital
Slot machine symbols have come a long way since the days of the one-armed bandit. In early old mechanical slots, simple but charming symbols were painted onto spinning drums, with icons including fruit, bars, bells, and lucky 7s.
With the rise of video slots, symbols began to evolve, with digital slot games introducing animated graphics, interactive symbols, and thrilling features like wilds and scatters.
Fast-forward to today, and symbols and their roles in slot games have expanded dramatically. Not only have innovative features like Megaways changed how they behave, but they’re a way for game designers to immerse players or even tell stories. The result? A more engaging and entertaining experience, with slot themes catering to every taste.
