It is clear that video slots are extremely popular among casino enthusiasts, attracting more players than any other type of game. Just like the classic slots that preceded them, video slots are very easy to play, making them a favorite of both novice and experienced players.
Not only are video slots easy to play, but they can also deliver exceptionally generous payouts. This is yet another reason why so many players enjoy wagering on video slots. Moreover, most major progressive jackpots are won on video slots, making this gaming genre even more popular.
No matter which online casino you visit, you will notice that the largest game category almost always features video slots. Most software providers continuously develop video slots with captivating visual effects, engaging themes, and diverse features that can significantly boost one’s balance.
How Video Slots Came to Be
1Creation
Video slots owe their existence to the old-school classic slot machine, which was first invented in the late 1890s. As these classic slots evolved into mechanical one-arm bandits, more players were drawn to the game.
Mechanical slots spread throughout the United States and other parts of the world. This widespread appeal led to continuous improvements, ultimately resulting in the creation of the first video slot machine in 1975.
2The First Video Slot Machine
The first video slot to appear on a casino floor was invented by Walt Fraley in 1975. The Fortune Coin was the first slot machine to feature a video screen that allowed players to watch the reels spin. However, it did not become very popular because most people were skeptical about the fairness of a game that lacked standard mechanical reels.
Since home computers were still uncommon, many players did not trust the computerized outcomes of video slots. In addition, these machines offered no advanced animations or sound effects, and the symbols looked flat and unattractive. These factors made the earliest video slot machines highly unpopular among players.
3A New Era of Video Slot Machines
Just one year later, International Game Technology (IGT) launched a number of video slot machines. The company hired the manufacturer of Fortune Coin and, over time, became the second-largest supplier of video reel slots.
4Video Poker Starts to Gain Popularity
By 1979, video slots had already gained significant popularity, which led to IGT’s launch of the first video poker machine, then known as SIRCOMA. Ironically, video poker became the first video-based casino game to be widely embraced by players. These machines opened the door for other video casino games that would eventually make IGT one of the top suppliers of video slot machines.
5First Video Reel Unit to Feature Several Games
In 1994, video slot entertainment evolved further with the Bally Game Maker, launched by Bally Technologies. It was the first unit to incorporate multiple video games, allowing players to select a title by touching icons on the screen. At the time, video poker and video blackjack were the most popular options, while video slots still had a smaller following.
6The mid-1990s Bring Video Slots More Popularity
Video slots gained wider recognition when Aristocrat Technologies began developing machines with 5 reels and special features. Although they debuted in Australia, these new slots quickly became hits in U.S. casinos. Their success motivated American manufacturers to enhance their own video slot machines and add engaging bonus features.
In 1997, WMS Gaming released Reel ‘Em In, the first wildly successful U.S. video slot machine. The game demonstrated how slot manufacturers needed to innovate if they wanted to remain relevant in the evolving market.
Factors that Made Video Slots the Most Preferred Gaming Option
Several years after the launch of Reel ‘Em In, 3-reel slots were still the top choice among casino players. That said, video slots began drawing in more users by offering advantages that traditional one-armed bandits simply could not match.
Thanks to the fresh designs and special features that manufacturers introduced, more U.S. players started seeking out more exciting slot variations. This allowed them to enjoy generous payouts and a new, engaging way to pass the time at the casino.
Features That Bring Bigger PayoutsTweaks in Design that Made Video Slots More Popular
While 3-reel slots were largely identical, featuring the same fruit symbols, video slots began attracting players with more varied gameplay. Inspired by books, movies, and other pop-culture phenomena, these games quickly became the new favorite way to gamble.
As slot manufacturers tried to draw in a broader audience, they focused on branding their games. Today, casinos feature video slots inspired by Michael Jackson, Lord of the Rings, The Twilight Zone, and countless other iconic pop-culture themes.
Another notable improvement was the addition of animations and immersive sound effects, which make every game even more engaging. Movie-themed slots, for instance, feature recognizable scenes that fans appreciate. To elevate the experience further, developers added audio that perfectly matches each slot’s theme.
Even with high-quality visuals and sound, developers looked for additional ways to enhance gameplay. Some land-based casinos now feature video slots with motion chairs, which sync with in-game actions. These chairs rock and shake, and built-in speakers provide surround sound, making every spin even more thrilling.
Features That Bring Bigger Payouts
Beyond adding animations and sound effects, slot manufacturers also made video slots more enticing by offering generous prizes.
Aristocrat was the first company to add a multi-tier jackpot to its machines, making its Hyperlink games extremely popular on casino floors throughout the Pacific Rim. The company later achieved great success in U.S. casinos with its jackpot slot Cash Express. Today, progressive video slots are often the top choice for players hoping to score substantial cash prizes that can reach hundreds or even thousands of dollars.
Bonus features also propelled video slots to the top of players’ lists. Whereas older machines typically included only a single free-spin feature, modern video slots – both online and offline – offer free spins, pick-a-prize rounds, and many other extras that make every spin more exciting and potentially rewarding.
Penny video slots are equally popular, letting players place very small wagers. To remain profitable, casinos typically offer penny slots with 20 or more paylines. This setup provides plenty of entertainment while giving players excellent value for each spin.

How RNG Ensures Fair Results in Video Slots
As mentioned earlier, back in the day, many players strayed away from video slots as they did not trust the fairness of the computerized spins. As the technology evolved, however, video slots became widely popular, with this genre being also the top pick for numerous online players. However, even in this day and age, there are still some concerns about the way results are determined when the reels spin virtually.
To make sure that the outcome of every spin of the reels is free of any bias, video slot developers are utilizing RNG software. This is a technology that ensures the fairness of slots, with online casinos regularly testing their RNG software to ensure their games always provide random results.
If we take a simpler approach, we might say that the way results are determined in mechanical 3-reel slots and video slots is pretty much the same. A number generator randomly selects numbers that are then translated into the symbols we see on the reels of the slot. There are, however, some video slot specifics that make the determination of an outcome slightly different when playing video slots.

Mechanical reel strips take space and cannot be too long in order for the number generator to determine an outcome

Video slot reel strips can be as long as a programmer needs them to be as they take no space

3-reel slots have fewer paylines or even just a single one so it is easier to generate results

Typically, video slots have multiple paylines that should be considered in the determination of an outcome

Mechanical 3-reel slots have fewer winning combinations

Video slots have a lot more possible winning combinations

It is not that common for mechanical reel slots to have bonus features, which makes generating winning combinations easier

Most video slots have one or more bonus features that must also be taken into account when generating outcomes
Common Features of Video Slot Paytables
In addition to the points noted above, several other video-slot features are worth discussing when it comes to winning combinations. Compared to mechanical 3-reel machines, video slots present both advantages and disadvantages that merit your attention.
Symbols Do Not Need to be Matched on Every Reel
Some Wins Pay Less Than the Total BetSymbols Do Not Need to be Matched on Every Reel
Because video slots feature more than three reels, they provide more opportunities for winning combinations. You don’t need matching symbols on every reel; most games pay out when only three identical symbols land on an active payline.
In an effort to make games even more appealing, many developers award payouts for just two high-value symbols on a line. Typically, these symbols must appear at the start of the payline, beginning with the leftmost reel. That said, some video slots also pay for combinations that begin on the rightmost reel.
Some Wins Pay Less Than the Total Bet
You may notice that some winning combinations pay less than your total stake. When you play a video slot, you set the wager for a single payline. That amount is then multiplied by the number of paylines you choose. Some slots let you select how many lines to activate, while others require a wager on every line.
Because you’re wagering on multiple paylines, your total stake per spin is higher than the single-line bet. Payouts, however, are calculated based on that single-line amount. As a result, lower-value symbols can yield returns that don’t exceed your total stake. Higher payouts usually require combinations of four or five matching symbols, whereas landing only two or three may result in a modest win.
Popular Bonus Features in Video Slots
Earlier, we noted that bonus features helped propel video slots to popularity. When you play online, you’ll find many video-slot variations that pack several bonus games into a single title. These extras can generate generous payouts, making the entire experience even more entertaining.
Free Spins
Cascading Reels
Pick-a-Prize Feature
Gamble FeatureFree Spins
The most common bonus in video slots is the free-spin round. How it is triggered varies from one game to the next.
Certain games grant a re-spin after every win, allowing players to boost returns on the same stake. More commonly, a free-spin round is triggered when a specific number of special symbols – often Scatters – appear. Usually, landing three or more Scatters anywhere in the base game activates the bonus. The number of awarded spins may be fixed or determined by how many Scatters triggered the feature.
During free spins, extra Wilds, multipliers, or Scatters can appear, sometimes retriggering the round and granting additional spins. In some slots, players even choose the number of free spins paired with a particular bonus modifier.
Cascading Reels
This feature is also common in modern video slots. It activates whenever a winning combination forms. The symbols in the win disappear, and those above cascade into the empty spaces.
This mechanism gives players a chance to create new wins without placing another bet. If the fresh symbols create another winning combo, the cascade repeats. Consequently, cascading reels can deliver a series of generous payouts on a single spin.
Pick-a-Prize Feature
Another well-liked bonus lets players pick a prize. Though it looks different in each game, the premise is the same: several concealed options appear, each hiding a reward.
In these rounds, players can win extra cash or multiply their current payout. Often, you’ll have multiple picks, giving you the opportunity to walk away with substantial rewards on top of your base-game stake.
Gamble Feature
Some video slots include a gamble feature that lets players increase their winnings. Unlike other bonuses, this option isn’t random; instead, you choose whether to risk your payout or collect it.
After any win, players can opt to gamble for a chance to double the amount. The risk usually involves a simple guessing game – such as selecting heads or tails or choosing the color of a face-down card.
A correct guess doubles your win and often lets you gamble again to increase it further. A wrong pick, however, forfeits the entire amount. For thrill-seekers, this feature offers the chance to ride a long streak of correct guesses and substantially boost their bankroll.
Popular Video Slots to Try
With so many video slots available online, choosing where to start can feel overwhelming. As major and boutique developers alike release fun, rewarding titles, players can explore games featuring diverse themes, audio, bonus features, and jackpots.
That said, if you want to sample some of the best options, give the following titles a spin. Special symbols, multiple paylines, and engaging bonuses are just a few advantages these games provide.
Immortal Romance
Buffalo Blitz
Wolf Gold
Gonzo’s QuestStarburst
Starburst ranks among the most popular online video slots at NetEnt-powered casinos. Developed by one of the industry’s leaders, it includes all the key elements that make a game both entertaining and rewarding.
The slot features five reels, three rows, and ten fixed paylines. Space-themed graphics and vibrant colors create an engaging atmosphere, and every spin can award up to 500× your stake. Classified as low- to medium-volatility, Starburst delivers frequent, though modest, wins with the occasional larger payout.
Regular symbols consist of sparkling gems plus the classic BAR and 7 icons. The key feature is the exploding star Wild, which appears on reels 2, 3, and 4, helping you complete winning lines. When it lands, the Wild expands to cover the reel and awards a re-spin. Players can enjoy up to 13 consecutive re-spins.
Immortal Romance
Immortal Romance comes from Microgaming, another heavyweight in the iGaming arena. The slot offers five reels and 243 ways to win, giving players ample chances to score payouts. Its medium volatility ensures a balanced mix of frequency and size of wins.
Inspired by vampire romance novels, the game features several charming, mysterious characters that drive its narrative and bonuses. Classic card values serve as low-paying symbols, while thematic items and characters deliver higher payouts. Wilds and Scatters add extra excitement.
Wilds and Scatters unlock several special features, such as turning entire reels Wild or launching tiered free-spin rounds with unique modifiers. The more often you trigger free spins, the richer the rewards become. Overall, Immortal Romance delivers a mix of suspense and solid payout potential.
Buffalo Blitz
Online players should also check out Buffalo Blitz by Playtech. This title from another industry giant offers an action-packed experience and the possibility of hefty rewards. As a high-variance slot, small wins are infrequent, but bonus features can deliver sizable payouts.
The game uses six reels and four rows, providing 4,096 ways to win. Any matching symbols on adjacent reels, beginning with the leftmost, result in a payout – their exact positions on the reels don’t matter.
Low-value symbols pay when three or more appear on consecutive reels, while premium symbols pay with just two. Wilds and Scatters further boost your chances of scoring large wins.
Wilds substitute for other symbols and can apply random multipliers during free spins. Landing three or more Scatters anywhere on the reels awards up to 100 free spins. With a bit of luck, these features can turn your session into a highly rewarding adventure.
Wolf Gold
For an even more exciting session, consider Wolf Gold. This Pragmatic Play release is both entertaining and rewarding, making it well worth your attention.
Wolf Gold features five reels, three rows, and 25 paylines. Any combination of three or more matching symbols on a payline results in a win. Various animals serve as high-paying symbols, while the wolf itself acts as the Wild, substituting for other icons. During free spins, the Wild expands to cover reels 2, 3, and 4.
The slot’s Scatter appears on reels 1, 3, and 5. Landing all three awards five free spins, and hitting another trio during the round retriggers the feature, granting three additional spins. There’s no limit to how many times you can retrigger it.
Another highlight is the full-moon Money symbol, which displays either a random cash amount or a mini or major jackpot. Landing six or more activates the Money Respin feature: the triggering symbols lock in place while the rest of the grid clears. You receive three respins to collect additional Money symbols, and each new full moon resets the counter to three.
Gonzo’s Quest
Another standout title is Gonzo’s Quest. This NetEnt classic invites players to uncover hidden treasures and explore legendary riches.
The game uses five reels and three rows, with wins paid across 20 fixed paylines. As a medium-volatility slot, it offers a balanced mix of win frequency and size.
The narrative follows the famed conquistador Gonzalo Pizarro y Alonso in his quest for El Dorado. Symbols depict animals and ancient masks carved into vibrant stones, paying when three or more identical icons appear on a line.
The slot includes special symbols such as Wilds and Scatters. Wilds substitute for other icons to complete wins, while the Free Fall Scatter triggers ten Free Fall rounds when three land on a payline. The feature can be retriggered for additional rounds.
Gonzo’s Quest also boasts the Avalanche mechanic: after every win, the contributing symbols vanish and new ones fall into place. Consecutive Avalanches can create additional wins and apply increasing multipliers to boost your payout.
