Symbols are the essence of online slot games because they form the winning combinations that provide prizes. If you are new to reel-based games, our guide on how to play slots explains how symbols, paylines, and spins work together. Different slots have their own icons based on their themes, but for classics, you’ll find mostly the same options — fruits, hot 7s, bells, and bars. Some games include extras that trigger bonus rounds or offer more coins. Before diving further into how classic slot machine symbols work, let’s go back to their roots.
History of Classic Slot Symbols
In 1895, Charles Fey in San Francisco invented the Liberty Bell, which became known as the first slot machine. The game had three spinning reels with five symbols: diamonds, spades, hearts, horseshoes, and a liberty bell. It introduced the mechanic of pulling a lever to spin the reels and winning when you land the same symbols. Lining three Liberty bells resulted in the largest win; hence, the machine’s name.

The Liberty Bell’s popularity became so widespread that many other companies created similar machines. Fast forward to the early 20th century, when slot machines faced their first major hurdle due to the implementation of certain gaming laws. These restrictions prevented vendors from paying actual funds to winners. To circumvent these laws, manufacturers offered gum prizes instead.
All manufacturers then rebranded slot machines to feature fruits that matched the gum flavors they offered. So, if players land three oranges, they get orange-flavored gums. The cherry became one of the most iconic during this period because it provided the highest prize. Soon after, developers introduced candy bars to these games.
As technology advanced, so did slot machines. Software providers entered into the picture, creating online versions of these games. Many companies explored other themes, introducing various icons, each with their respective payouts. However, some recreated the nostalgic effect of land-based slots by producing online classics with the same fruity theme and symbols.
You’ll find the best free slots inspired by land-based games at top sweepstakes and social casinos. Such sites in the U.S. offer no deposit bonus coins that you can use to spin the reels of these games without spending anything. You only have to register and verify your identity to get started.
Common Classic Slot Symbols and Their Meanings

One of the fastest ways to identify classics is by their symbols. Some titles also have names that reflect their theme. However, you’ll immediately notice the familiar fruits and hot 7s once you look at their display icons Here are the most common classic slot symbols and what they represent:
Fruits
Watermelons, oranges, lemons, and grapes became popular when there was a federal ban on gaming activities. These symbols have since stuck, becoming a preferred option to horseshoes and poker card suits that appeared in the Liberty Bell.
Among these fruits, the cherries are the most appealing. That’s because they pay out the most. Plus, unlike other symbols that must land on a line to pay, three cherries only need to appear anywhere on the reels to gift players.
Bars
These are other slot machines symbols that have stood the test of time. They are represented by a single, double, or triple bar. The logo of the Bell-Fruit gum company inspired these icons. Today, they appear in online versions but as regular icons like fruits.

Bells
Bells were part of the earliest slot machines. They were included as a nod to the Liberty Bell and remain one of the most crucial icons in slot games. Some online slots now make bells and special symbols that give players more coins than other symbols.
Lucky 7s
The number 7 is like the main character of classic slots. While it wasn’t in the first machine, it appeared in other early versions. Manufacturers added these slot machine symbols due to religious beliefs and old superstition.
Many people consider 7 to be the luckiest number. Slot designers grabbed onto this idea and ran with it. The Hot Triple 7 slot is a clear example of how lucky 7s became the centerpiece of classic-style reel design. In most games, landing three 7s is like hitting the jackpot, as it often triggers the biggest payout in the game.
Lucky 7s remain one of the most recognizable classic symbols, and they appear as premium icons in Diamond Explosion 7s.
Special Symbols in Classic Slots

In addition to the regular classic slot machine symbols, you’ll find other significant icons in these games. These unique options were not in the early slot machine versions; developers incorporated them mostly in online variants. Below are the most common ones:
Wild Symbols
The wild is one of the most beneficial additions to online slots. In some games, these symbols can stand on their own and give you a prize if you land three or more of them on an active winline. However, their major function is being able to replace other symbols and complete winning combinations.
For instance, you need three lemons on a winline to get a prize, but you only land two. If the third icon that falls on that winline is a wild, you get your corresponding gift because the wild acts as a lemon. While these symbols can substitute for other icons, there is one it cannot replace — the scatter.
Scatter Symbols
These unique elements in online slots function differently from standard reel symbols. Their primary characteristic is the ability to award payouts or trigger special features regardless of their position on the reels.
In most slot games, scatter symbols don’t need to appear on a specific winline to be effective. They typically activate when a certain number (usually three or more) appear anywhere on the reels during a spin.
Bonus Symbols
Earlier slot machines had a basic gameplay – spin the reels and hope to win. However, slot developers took their gameplay to another level by including bonus features like free spins. These extra elements might not be as many as those you’ll find in more sophisticated, but they provide larger wins.
Triggering these features is possible when you land bonus symbols. Some of the clearest examples of symbol-driven bonus play appear in Hold and Win slots, where bonus symbols lock in place during respins. The exact bonus symbol depends on the game. Sometimes, it might be a different-looking hot 7 or a flaming bar icon. You might also need to land a specific number of these bonus symbols to kickstart the bonus round.
The Role of Classic Symbols in Modern Slots
Classic slot symbols like cherries, bells, and lucky 7s aren’t going anywhere. Game developers have found clever ways to keep these old-school icons fresh and exciting in today’s digital slots, and our Joker’s Jewels review shows how one modern release keeps that classic reel identity intact. You’ll often see fruit symbols with a modern makeover with glossy 3D graphics or quirky cartoon faces to make the experience more exciting. Lucky 7s might burst into flame or start spinning when you hit a winning combo.
These symbols tap into a sense of nostalgia for many players. There’s something comforting about seeing those fruits line up, even if you’re playing on your phone instead of pulling a physical lever. For older players, it might bring back memories of casinos from previous decades. Younger folks might associate them with retro design or their grandparents’ favorite games.
Significance of Slot Symbols in Modern Games
Slot symbols have grown past fruits, bells, and bars. Now, more modern games have better-looking icons, depending on their themes. For instance, you’ll find Pharaoh, scarab beetles, and other symbols in an Egyptian-inspired option.
Besides slots, there are crash casino games that have a different but also simple gameplay. They revolve around multiplier values that increase at the beginning of the game round. Your goal is to take out your winnings before the game crashes.
Conclusion
Now that you know the meaning of slot machine symbols, you understand their significance in these games. Without them, the reels will be bare, making it impossible to play, let alone land winning combinations.
