Slot machine symbols explained: a beginner’s guide
Slot machine symbols are at the heart of how slot machines work. Whether you are exploring classic slots inspired by the Liberty Bell slot machine or modern slot machines with advanced bonus rounds, understanding the role of symbols helps you play with confidence.
Today’s slot machines combine rich history, innovative mechanics, and blockchain-powered gameplay. If you enjoy playing slot machines at a crypto casino like BiggerZ, knowing what each symbol means will improve your overall experience.
This guide explains slot machine symbols, their impact on payouts, and what beginners should consider before starting to play.
What are slot machine symbols?
Slot machine symbols are the visual icons that appear on the reels of slot machines. When the spinning reels stop, the symbols that land on active paylines determine whether you form winning combinations.
In traditional slots, the structure was simple:
- Three reels
- One payline
- A limited number of machine symbols
The earliest slot machines, including the famous Liberty Bell created by Charles Fey in the late 1800s, featured classic slot machine symbols like:
- Bells
- Playing cards
- Horseshoes
Modern slot machines, however, can include five drums or five reels, multiple paylines, and dozens of different symbols.
So, how many different symbols are in a slot machine?
There is no fixed number. Many slot games use between 8 and 15 different symbols, while more complex slots may include additional bonus symbols and special icons tied to the game’s theme.
A short history of slot machine symbols
To understand the meaning of slot symbols today, it helps to look back.
In the early days, Charles Fey introduced the Liberty Bell slot machine with three reels and automatic payouts. The bell symbol, especially three bells aligned, offered the highest reward.
Later, companies like the Mills Novelty Company added fruit symbols to avoid gambling restrictions. That’s where fruit machines originated. Symbols such as:
- Cherries
- Lemons
- Plums
- Oranges
were associated with chewing gum flavors sold by the Bell Fruit Gum Company. The famous bar symbol also emerged during this era.
Even today, many slot machines include fruit symbols, playing card symbols, and bar icons as a nod to their rich history.
Standard slot symbols
In modern slot machines, standard slot symbols are divided into two main categories:
Low-value symbols
Low-paying symbols usually include:
- Playing card symbols (J, Q, K, A)
- Card suits
- Number icons
These classic symbols appear frequently on the reels and typically offer lower payouts.
[H3] High-value symbols
The highest paying symbols are often connected to the game’s theme. For example:
- Ancient Egypt-themed slots may feature pharaohs
- Adventure slots may show explorers
- Fantasy games may include mythical creatures
These machine symbols appear less frequently but offer a higher payout when part of winning combinations.
Many slot games rely on themed designs to create immersive gameplay with flashing lights, animations, and interactive effects.
Wild symbols explained
One of the most important slot machine symbols to understand is the wild symbol in slots.
What are wild symbols in slot machines?
Wild symbols substitute for other symbols to help form winning combinations. If you have two matching icons and a wild appears on the same symbol’s line, it can complete the win.
There are several variations:
- Expanding wilds – cover an entire reel
- Stacked wilds – appear stacked vertically
- Sticky wilds – sticky wilds stay in place for multiple spins
- Multiplier wilds – increase the payout value
Expanding wilds can dramatically increase the chance of forming multiple winning combinations. Sticky wilds are common in bonus rounds, while multiplier wilds boost rewards.
Wild symbols usually cannot replace scatter symbols or bonus symbols.
Scatter symbols and free spins
Scatter symbols play a unique role.
Unlike regular symbols, scatter symbols do not need to land on specific paylines. Instead, they activate features based on how many appear anywhere on the reels.
Scatter symbol explained simply:
- Land 3 or more scatters
- Trigger bonus rounds
- Often triggers free spins
Free spins are one of the most popular special features in many slot games. During these rounds, players can spin without using their own money while still having a chance to win.
Some games also award scatter wins — direct payouts without activating bonus games.
Bonus symbols and special features
Bonus symbols in slots often include unique icons that unlock interactive features.
These may:
- Trigger bonus rounds
- Activate mini games
- Unlock multiplier features
- Expand reels
- Award extra cash prizes
In today’s slot machines, bonus rounds often include immersive mechanics tied to the game’s theme.
For example:
- Pick-and-click mini games
- Reel expansions
- Increasing multipliers
Bonus games can significantly impact total payout potential, but outcomes remain completely random.
How slot symbols affect payouts
Understanding how slot machine symbols influence payouts is essential before you start playing.
Every game includes a paytable, which shows:
- The value of each symbol
- The number of matching icons required
- The payout multiplier
Winning combinations occur when matching symbols align across active paylines.
Low-paying symbols provide smaller multipliers. High-value machine symbols deliver higher payout potential. Wild symbols improve combination possibilities, and scatter symbols can unlock free spins.
Checking the paytable in more detail helps you understand volatility, RTP (Return to Player), and risk level.

Are there any trademarked slot machine icons?
Yes, some slot machine symbols are trademarked.
For example:
- The original Liberty Bell design
- Certain branded character icons
- Licensed entertainment-themed images
Game developers often protect unique symbols tied to intellectual property. However, classic symbols like cherries or playing cards are not exclusive.
What is the lucky symbol on a slot machine?
There is no universal lucky number or lucky symbol guaranteed to win.
Historically, three bells were considered lucky because they offered the top prize in early machines. In other regions, symbols like the number 7 are considered lucky.
However, slot machines operate using Random Number Generators (RNG). Outcomes are completely random and independent of previous spins.
Tips for understanding slot symbols before you play
Before playing slot machines, consider these steps:
1. Review the paytable
This explains symbol values, paylines, and special features.
2. Understand special symbol rules
Wild symbols and scatter symbols function differently in many slot machines.
3. Choose games that match your risk level
High-volatility slots offer larger but less frequent payouts. Low-volatility slots provide smaller, more consistent wins.
If you are new, start with classic slots featuring simple mechanics before exploring complex bonus rounds.
