Slot Machine Symbols: History, Meaning and What They Do

15 October 2026 · Slotupia Team · Slot Guides

Why symbols matter

Symbols are the language of a slot game. They tell you at a glance what's valuable, what triggers features and what the theme is. Knowing what each kind of symbol does makes any new game easy to read.

The original symbols

The Liberty Bell machine of the 1890s used horseshoes, diamonds, spades, hearts and a bell. Three bells paid the top prize, which is where the machine got its name. Those card suits and lucky charms set the tone for decades.

Fruit and the "bar"

In the early 1900s, some machines paid out in chewing gum rather than coins to get around gambling laws, and fruit symbols such as cherries, lemons, plums and oranges represented gum flavours. The BAR symbol is widely believed to come from the logo of a gum company. That's why fruit and bars are still called "classic" symbols today, and why games like Neon Sevens and Fruit Fiesta use them.

Lucky sevens

The number seven has long been considered lucky, and "777" became the classic top combination on many machines. It remains the most recognisable slot symbol in the world.

Bells, stars and diamonds

Bells survived from the Liberty Bell; stars and diamonds were added as high-value symbols that look exciting on lit-up machines. In Slotupia's own icon you'll see a gold star, a cyan gem and the neon S on the reels, a modern nod to that tradition.

Modern symbol types

• Low-value symbols: often card ranks (10, J, Q, K, A) or simple gems. They appear often and pay small amounts.
• High-value symbols: the themed pictures: animals, gods, dragons, treasure. Rarer and worth more.
• Wilds: substitute for other symbols to complete wins. See wild symbols explained.
• Scatters: pay or trigger features anywhere on the reels, usually free spins.
• Bonus symbols: trigger a mini-game or a hold-and-spin feature.
• Coin or cash-style symbols: carry values collected in features (in Slotupia, coin values only).
• Multiplier symbols: boost wins they're part of.
• Mystery symbols: reveal a random matching symbol.

How symbols pay

The pay table lists each symbol with the payout for 3, 4 or 5 matching on a line or way, usually starting from the left. Higher-value symbols pay more, and wilds often have their own top payout too. Learn to read it fast in our pay table guide.

Symbol frequency and reel strips

Each reel has a strip with many positions. Low-value symbols appear on more positions; high-value and special symbols on fewer. That's why premium combinations are rarer. The RNG chooses the stop position, so every spin is independent.

Themes and symbols

Themes change the art but not the job each symbol does. A lion in a safari game and a dragon in an Asian fortune game may both be top-paying high-value symbols.

Tips for tournaments

• Know which symbol is the scatter; three of them usually start free spins.
• Watch for wilds on middle reels, where they can complete many lines.
• Don't chase near misses; they mean nothing for the next spin.

Summary

From bells and fruit to sevens and gems, slot symbols carry 130 years of history. Today they fall into a few types (low, high, wild, scatter, bonus), and once you know them, every game makes sense. Try them in free tournaments.

Symbols in Slotupia's brand

The Slotupia icon shows a three-reel window with a gold star, a cyan gem and the neon S, framed by gold light bulbs like a classic casino machine. It is a deliberate nod to slot history: the star and gem echo the high-value symbols of classic machines, while the S stands for Slotupia itself.

Reading symbols quickly on a small screen

On a phone, symbols are small, so learn their colours as well as their shapes. Most games make high-value symbols larger, brighter and more detailed than low-value ones, and special symbols often carry a label such as WILD, SCATTER or BONUS. After a few spins you will recognise them instantly.

Symbol myths

Some players believe certain symbols are "due" after not appearing for a while, or that seeing two jackpot symbols means the third is coming. Neither is true. Each reel stop is chosen independently by the random number generator on every spin.

Symbols around the world

Different regions have favourite symbol sets. American machines leaned on bars, sevens and bells; British fruit machines kept cherries, lemons and plums; Asian-themed games favour dragons, koi and gold coins; African-themed safari games use lions, elephants and drums. Slotupia's line-up draws on several of these traditions, from neon sevens to safari.

Key takeaways

• The Liberty Bell machine introduced bells, horseshoes and card suits.
• Fruit symbols spread when machines paid out in gum and sweets.
• The BAR symbol is linked to the Bell-Fruit Gum Company logo.
• Lucky sevens became the classic top symbol on three-reel games.
