From vintage bars and bells to dazzling digital displays, slot machine reels have transformed immensely over the years. Once purely mechanical, today's slots combine technology and entertainment, offering more than just a chance to win. Dive into this article to discover the journey of slot reels and how they shape our modern gambling experiences. Let's spin the story!
What are slot reels?
Chances are you’ve at least seen a slot machine in some form. Most people know the general look and design of a slot. Players drop in a few dollars (actual slot tokens or coins in the old days) and then press the spin button or pull a handle.
This puts the reels facing outward from the slot cabinet in motion. These spin vertically and eventually come to a stop, signaling whether a player has won or lost. The reels feature various slot symbols that relay the type of a particular spin. Players will often become accustomed to seeing some familiar symbols that may have been part of the world of slots since their invention in the late 1800s. Some of those common and popular symbols include:
Bells
Bars
7s
Playing card hands (A, K, Q, J, 10)
Playing card suits (hearts, diamonds, clubs, spades)
Fruits
These certainly aren’t all the symbols a player will find in a random slot. However, these classics are still found in numerous games from Las Vegas and Atlantic City to Monte Carlo and Macau. Modern video slots make use of high-energy themes and unique narrative arcs, so many games have moved beyond these classic symbols on the reels.
Some symbols also offer some extra winning power for players. Those include:
Wilds – These can usually be substituted for other symbols on the reels, allowing for more winning combinations.
Scatters – These unlock bonus features such as free spins and other bonus games. These can offer players extra ways to win including the possibility of some big prizes.
Multipliers – These multiply a regular win by a certain amount.
Most games feature three reels but more modern games have seen that expand depending on the game. As slot manufacturers have innovated, additional opportunities to reveal symbols have been added. Some games even feature a completely separate set of secondary reels. But on older reels and even many still today, three reels are a popular combination.
The general idea remains the same, however, more than 100 years after the first slot machines were unveiled for eager players. A player drops in some money and spins those slot reels, eagerly awaiting which symbols show up when those whirling reels come to a stop – hopefully a nice jackpot.
How Many Reels Are On A Slot Machine?
A typical slot machine, whether found in a traditional brick-and-mortar casino or an online gaming platform, typically features three to five reels. These reels are vertical columns that display various symbols and symbols on them, and they spin when a player activates the machine.
The number of reels can vary from one machine to another, with three-reel slots being the simplest and most classic version, while five-reel slots are more common in modern gaming. The number of reels directly influences the complexity of the game and the potential combinations, adding an element of excitement and strategy to the player's experience.
However, there are also specialized slot machines with more than five reels, offering even more diverse gameplay options and winning possibilities for adventurous players.

How do slot machine reels work?
Up until the age of computers and modern technology, slot machine reels would spin because of real mechanical engineering within the slot cabinet. A series of gears and levers were used to crank up those reels. The handle out of the side of the machine was used to “spin” the reels by releasing a braking mechanism and putting them into motion. A series of kickers and a stopper eventually bring the reels to a stop, leaving the gambler with a few symbols showing on the front of the cabinet. If they line up just right on the pay line, the player is rewarded with a payout. Some of those can occasionally be massive jackpots, but those odds are long.
Slot Machine Reel Strips
In the intricate world of slot machines, the composition of the reel strips plays a pivotal role in determining the outcome of each spin. These "reel strips" are physical strips of paper or later, plastic, containing various symbols. Each strip corresponds to a specific reel, and the arrangement of symbols on these strips influences the odds and potential payouts of the machine. As the reels spin, these strips move in synchronization, dictating which symbols align on the payline when the reels come to a halt. The careful design of these strips has a profound impact on the excitement and anticipation of each spin, making them an integral part of how slot machine reels work, both in the mechanical classics of yesteryears and the modern digital incarnations of today.
Most modern slots, however, don’t even feature traditional mechanical reels. Instead, players will find “video reels” that mimic those vintage slots of old Vegas. These machines feature mostly computer and software components, including an algorithm, to make them function. These games use RNGs (random number generators) and an algorithm to make the reels spin and award wins and losses.
Some machines may feature what seem like mechanical reels. However, these reels are spun by the computer and software in the cabinet and not from some mechanical movement generated by the user as they once were by a player pulling an external handle.
The slot’s software has already determined the result of the spin when a player presses the spin button. The reels offer players just a visual representation of that selection with the bells, whistles, music, bonus games, etc., all part of the entertainment that comes with the machine. But those entertaining qualities keep players coming back for more of the action.
Research firm Technavio estimates the industry’s compound annual gross revenue to rise almost 13% from 2020-25, topping out at almost $9 billion. Manufacturer creativity seems to be driving demand for more creative and better products.
The growth of the slot machine market will be driven by the growing vendor involvement in the market,” the study notes. “The vendors in the market are launching new products. They are attracting more consumers by introducing slot machines with improved features. Digital slot machines are considered to be extremely user-friendly because they display all of the information in the form of comments and let players play without any aid or assistance. These characteristics have resulted in high demand for these devices in casinos.

The vast majority of players won’t ever experience those kinds of jackpot odds. Still, many players enjoy some modest winnings and entertainment, spinning slot reels here and there from the couch, subway, or maybe even on a park bench.
