Have you ever wondered what all those colorful symbols spinning on slot machine reels mean? From classic fruits and bells to mysterious Wilds and Scatters – every symbol has its function and history. In this comprehensive guide, we’ll discover the meaning of various slot machine symbols, their origins, and how they affect your gameplay and potential winnings.
The History of Slot Machine Symbols
Slot machines have a fascinating history dating back to the late 19th century. The first modern slot machine, known as the “Liberty Bell,” was invented by Charles Fey in 1895.
The original Liberty Bell machine used only a few simple symbols: liberty bells (hence the name), horseshoes, and playing cards. These early symbols shaped a tradition that continues to this day. The bell symbolized America’s freedom and independence, as well as the highest payout in the machine.
With the introduction of Prohibition in the US in the 1920s, gambling became illegal. To circumvent the law, slot machine manufacturers began using fruit symbols, and machines paid out fruit-flavored gum instead of money. This is where the term “fruit machines” originated, which is still used in the United Kingdom.
The transition from mechanical slot machines to digital video games in the 1990s and 2000s revolutionized symbol design. Suddenly, developers were no longer limited by physical reels and could create an infinite number of symbols with special functions and animations.
Classic/Standard Symbols
Fruit Symbols
Fruit symbols are some of the most recognizable elements of slot machines. The most common fruits include:
- Cherries – often offer the smallest but most frequent wins
- Lemons – a classic low-value symbol
- Oranges – usually of medium value
- Plums – traditionally higher value than smaller fruits
- Grapes – typically of higher value
- Watermelons – often one of the most valuable fruit symbols
The symbolism of fruits has stood the test of time and is still used in many modern slot machines, especially those referencing the classic style.
BAR Symbols
The BAR symbol is another classic slot machine element. It was initially modeled after the Bell-Fruit company logo, a manufacturer of slot machines and chewing gum, though this history is questioned by some gambling historians.
BAR symbols often come in three variants:
- Single BAR
- Double BAR
- Triple BAR
The more BAR stripes, the higher the payout. In some machines, a combination of different BAR symbols can also lead to a win, although usually smaller than for identical symbols.
Lucky Sevens
The number 7 symbols are considered some of the luckiest and most valuable in the slot machine world. They derive from playing cards and traditionally offer the highest standard payouts. Red sevens are the most popular, but there are also gold, silver, and other variants.
Card Symbols
Card symbols (A, K, Q, J, 10, sometimes 9) are common in many modern video slots. They are typically the lowest value symbols, with the ace being the most valuable in this group. Their popularity stems from their ease of recognition and connection to other casino games.
Special Symbols and Their Functions
In addition to standard symbols, modern slot machines offer a range of special icons that significantly impact gameplay and potential winnings.
Wild Symbols
Wild symbols work similar to jokers in cards – they can substitute for almost all other symbols (usually except for Scatters and Bonuses), helping to create winning combinations. They are some of the most important symbols in modern slot machines.
Different types of Wild symbols:
- Standard Wilds – substitute for other symbols
- Expanding Wilds – after appearing, they expand to cover the entire reel
- Stacked Wilds – occupy multiple positions on a single reel
- Sticky Wilds – remain in place for several spins
- Walking Wilds – move across the reels in subsequent spins
- Multiplier Wilds – not only substitute for symbols but also multiply winnings
Scatter Symbols
Scatter symbols are unique because they don’t need to appear on an active payline. They can be placed anywhere on the reels and still activate special features. Most commonly, three or more Scatter symbols activate a round of free spins.
Importantly, winnings from Scatter symbols are usually multiplied by the total bet, not just the line bet, which can lead to significantly higher payouts.
Multiplier Symbols

Multiplier symbols increase the value of a win by a specific multiplier. For example, an x2 symbol doubles the win, x3 triples it, and so on. These symbols can be standard symbols or special ones that appear only under certain circumstances, such as free spins.
Multipliers can also be combined with Wild symbols, creating Wild Multipliers that both substitute for other symbols and increase the value of the win.
Bonus Symbols
Bonus symbols are used to activate special bonus rounds or mini-games. These can be “pick a box” games, “pick a card” games, wheels of fortune, or other interactive elements that offer additional chances to win.
Unlike Free Spins, which are often activated by Scatters, bonus games typically require Bonus symbols to appear in specific positions or on winning lines.
Modern Symbol Variations
Contemporary video slots constantly innovate in terms of symbol functions to increase excitement and potential winnings.
Sticky Symbols
Sticky symbols remain “glued” to their position for a specific number of spins or until a special feature ends. These can be both regular symbols and special ones (e.g., Sticky Wilds). As Sticky symbols accumulate on the board, the chance of forming larger combinations and higher wins increases.
Expanding Symbols
Expanding symbols extend to cover the entire reel after appearing, significantly increasing the chances of winning. Expanding Wilds are the most common, but there can also be other expanding symbols depending on the slot machine.
Stacked Symbols

Stacked symbols occupy more than one position on a reel, significantly increasing the chance of forming a winning combination. They can occupy 2, 3, or even the entire reel, and in some slot machines, symbols can be stacked on all reels.
Progressive Symbols
Progressive symbols are associated with progressive jackpots. Collecting these symbols or hitting a specific combination can activate a jackpot round or contribute to increasing the jackpot pool. Winnings from progressive jackpots can be enormous, reaching millions.
How Symbols Affect Gameplay and Payouts
The Relationship Between Symbol Rarity and Payout Value
In slot machines, the reward for a symbol combination is always inversely proportional to the frequency of that symbol. For example, in the popular game “Buffalo,” lining up three common 9 symbols yields a win of 5x the stake, while lining up three rare Buffalo symbols gives 200x the stake.
How Combinations Work
There are two main systems for creating winning combinations:
- Payline system – symbols must appear on specific lines, usually from left to right. Traditional machines had 1-5 lines, modern ones can have 100 or more.
- Ways-to-win system – there are no predefined lines; a win occurs when matching symbols appear on adjacent reels, usually from left to right. Slot machines can offer 243, 1024, or even more ways to win.

Symbol Distribution on Reels
In traditional mechanical slot machines, the distribution of symbols on reels was visible, and you could count the number of individual symbols. A typical reel had about 20 symbols, and an entire machine with three reels allowed for over 8,000 combinations.
In modern digital slot machines, symbol distribution is controlled by a random number generator (RNG), and the probability of each symbol appearing is programmed. This means that rare, high-paying symbols may have a much lower probability of appearing than the reel layout would suggest.
Conclusion
Slot machine symbols have evolved from simple bells and fruits to a sophisticated system of icons with a variety of special functions. Understanding the meaning and functions of these symbols can significantly enhance your gaming satisfaction and help you make more informed decisions.
Remember that slot machines are primarily a form of entertainment. Always play responsibly, set time and financial limits, and never treat gambling as a way to make money.
