Slot machines are among the most iconic games in casinos, both online and offline. Their colorful symbols, spinning reels, and familiar sounds create an engaging experience. But have you ever stopped to wonder what those cherries, bars, and 7s really mean? Slot symbols aren’t just random images—they carry history, gameplay significance, and even psychological appeal. Understanding what these symbols stand for can deepen your appreciation of the game and possibly help you play more strategically. In this article, we’ll break down the origins, meanings, and types of slot symbols, from the vintage classics to today’s wildest icons.
Origins of Slot Symbols
The first slot machines were invented in the late 1800s and featured simple symbols like horseshoes, bells, and playing cards. These early slots were mechanical devices, and their symbols were painted on physical spinning drums. The bell symbol became synonymous with slots due to the Liberty Bell machine, which paid out when three bells lined up. Eventually, fruit symbols like cherries, lemons, and plums were introduced—originally representing flavored chewing gum as a workaround for anti-gambling laws. Over time, these symbols stuck, and even digital slots often include them today as a nod to tradition.
Wilds, Scatters, and Bonuses

In modern video slots, you’ll see more than just fruit and bars. Special symbols have evolved to enhance gameplay. The Wild symbol acts as a substitute, helping complete winning combinations. Think of it as a joker in a deck of cards—it can be whatever you need it to be. Scatter symbols, on the other hand, usually trigger free spins or bonus rounds, often paying out even if they don’t appear on adjacent reels. Then there are Bonus symbols, which often launch mini-games or interactive features. These symbols add depth and variety, keeping the gameplay fresh and exciting.
Classic Symbols and Their Meanings
Classic slot symbols like cherries, lemons, bells, and BARs come from the earliest machines. Cherries typically offered a small win, making them the easiest payout. Lemons and other fruits added variety. The BAR symbol actually stems from the Bell-Fruit Gum Company logo, which used a stylized bar of gum. The number 7 is often considered lucky and traditionally delivers the highest payout in many classic games. These old-school symbols remain popular because they’re easy to recognize and invoke nostalgia, especially for seasoned players who started in brick-and-mortar casinos.
Themed and Branded Symbols

As slot games evolved, developers began adding themed symbols to reflect pop culture, movies, and mythology. In an Egyptian-themed slot, you might see scarabs, pharaohs, or pyramids. In a fantasy slot, dragons, swords, and wizards often dominate the reels. These symbols aren’t just eye candy—they usually tie into the slot’s narrative and bonus features. For example, a wizard symbol might trigger a magical multiplier. Branded slots go further, using licensed content from movies or TV shows. These symbols serve to immerse players in a story, offering an experience that’s as much about entertainment as gambling.
Symbol Placement and Strategy
Slot outcomes are ultimately controlled by Random Number Generators (RNGs), so no symbol placement is ever truly predictable. However, understanding paylines and reel setups can give you an edge in choosing the right game for your style. Some slots pay left to right, while others pay both ways or follow cluster patterns. Knowing what symbols trigger bonuses and which ones appear frequently—or rarely—can help set your expectations. Paytables provide this information upfront, so take time to review them. While there’s no surefire way to beat the slots, awareness of symbol functions can inform smarter gameplay.
