How Online Casino Slots Work

Random Number Generator

Before you play slots online for cash, it pays to research the subject at least a little bit.

This type of casino game relies purely on chance. When you press the Spin button, a random number generator (RNG) creates a 100% random outcome.

If the outcome it stops on is a winning one, you get paid. If it's not - better luck next time.

RTP & Variance

RTP (aka return to player) is a percentage relation between the total amount of bets that are placed in a slot and the total amount of winnings and the total amount of money it will pay out to players. RTP is expressed as a percentage. The higher it is, the fairer the slot machine.

The figure will always be below 100%. This difference is what allows the casino to cover operating expenses and still turn a profit.

If you are looking for a bargain, look for slots with an RTP of at least 96% or higher.

Volatility is a figure that tells you how often you will win money in online slots. It can be low, medium, and high. The lower the volatility, the more often you will win, but the lower your winnings will be. High volatility slots, on the other hand, have less frequent but larger payouts.

In general, players seeking to get the most entertainment for their dollar tend to choose low volatility slots.

On the other hand, high rollers who are interested in maximizing their win potential tend to prefer high volatility slots.

Pay lines and Rows

The pay lines are the lines that are counted for the purposes of assembling winning combinations.

To win, you usually need to line up at least three symbols on a pay line. If the three symbols appear on the reels but not on a pay line, you do not win your bet.

Every machine has its own pay line layout. The simplest machines can have as little as one pay line. The most complicated ones can have hundreds of thousands, with pay lines that can be activated horizontally (from left to right or vice versa), vertically, diagonally, on different levels, etc.

Scatters and Wilds

A Wild refers to a symbol that can substitute for any other symbol in the game to help the slots player create a winning line.

Scatters are unique symbols that don't need to appear on the winning line to help you win. In many cases, getting three scatters on the screen will launch the free spins round. It doesn't matter where they appear on the screen: the moment you see them, you can win!

Free Spins and Bonus Rounds

Bonus rounds are additional game rounds that you can unlock by landing a specific combination of wilds or scatters. It is exactly in these modes that most of the slot’s real money wins are to be found.

Bonus founds can appear in different forms: free spins, mini-games, risk options, etc.

Most of the slot machines that you will find at 20Bet offer one or more types of bonus rounds.

Among our best online slot bonus games, we can mention the one in Wolf Hunters by Yggdrasil.

This game not only has great free spins but also has a sticky wild that spices things up. If this symbol appears in the reels, you will receive several respins from which you can get many winning combinations.

Another casino game we recommend you try is Van Helsing's Book of the Undead from 1x2 Gaming. This one comes with an expanding symbol that occupies several reels to generate more winning combinations. It also comes with a different free spins feature for each high-value symbol, so you won't be wanting for variety.

Types of Online Casino Slots

Slot players love variety. Software providers know this, which is why there are so many different slot types in the world. Our top online casino has all the slots for real money you can think of. Here are just a few of the options.

Fruit Machines or Classic Slots

These are the slot machines that you could expect to find at your local bar a couple of decades ago. They usually have only three reels, just over ten pay lines, and include simple fruit symbols.

Unlike modern slot machines, these games do not typically include any gimmicks like bonus rounds or special gameplay features. So if you want to enjoy classic slot gameplay without any distractions, then this is the genre for you.

Branded Slot Games

Branded slots are games inspired by a pop culture franchise. These can be movies, musical groups, TV series, books, etc.

Playtech and NetEnt are the most prominent providers within this niche. For example, these gaming software developers have acquired the licenses to develop slot machines from the DC Comics and the Marvel universe.

Feature Buy Slots a.k.a. Bonus Buy

At 20Bet, we have a complete section dedicated to Bonus Buy online slots machines.

These games allow you to play a special bet that launches the free spins round immediately. So if you want to skip all the grind and get to the good stuff - this is the genre for you.

Spinomenal is one of the most prominent developers of this type of slot game, with titles like Age of Pirates and Goddess of Lotus being loved by fans.

Progressive Jackpot Slots

Progressive video slots are games with an accumulative jackpot that grows every time someone spins the reels and doesn't win.

In some cases, it is necessary to place a bet with a specific amount to participate in the jackpot. In others, the minimum stake allowed is enough.

At 20Bet, we have an entire section dedicated to this type of game. Currently, the total jackpots won through these games exceeds 57 million euros.

MobileSlots

As the name suggests, mobile slots are games that you can play on the go from your mobile device.

In general, these games have been programmed using HTML5 to guarantee their seamless scaling to any type of screen and operating system. What's more, all of them can be run in your browser, no download required.

New Online Slots on 20Bet Casino

Casino game providers know they cannot rest on their laurels. Which is why they constantly add new slots to their catalog.

You can find all the freshly-released slots in the "New Games" section of our top online casino.

All online new slots are available in demo version and with real cash for the members of our community of players. Every day you will find something fresh from the oven that you can try exclusively.

We also benefit you with specific bonuses for new slots. In addition, we make sure to include new table games to keep the experience fresh for all types of players.

Starburst

Starburst is one of the best online casino slot machines because it transports you to your local pub without leaving home.

We are talking about a slot with five reels and 10 pay lines. One of the reasons for its success is that playing it is very simple and straightforward. There are no multipliers, bonuses, or free spins. It's just you and Lady Fortuna.

Gonzo's Quest

Gonzo's Quest is probably NetEnt's flagship game. It regularly appears on the lists of the best online slot games and it doesn't look like its popularity will wane soon.

It has two unique features. One is an "avalanche" of falling symbols. The second one is the free spins. The avalanche can multiply your winnings by 15x.

Age of the Gods

Age of the Gods features 5-reels, 20-pay lines, and an RTP of 95.02%. It has a rather interesting free spins round and the setting is excellent. You'll meet Greek gods Athena, Zeus, Hercules, and Poseidon. They will offer you lovely prizes and unique mechanics, such as the multiplier, wilds, wilds, etc.

Mega Moolah

This is, without a doubt, one of the most popular slots in the world. Known as the millionaire maker, Mega Moolah features 5 reels, 15 pay lines, free spins rounds, and Wilds. But the reason it is known most of all is the fact that its progressive jackpot has made over 60 people millionaires.

A Night Out

A Night Out is one of 20Bet's best paying online slots. It has an incredibly generous RTP of 97%. This means that, on average, for every dollar you put in, you will get 97 cents back. In the casino industry, only blackjack and baccarat can compete with such a low house edge.

The game comes with two modes. You can choose whether to use 40 bet lines or double the size of your bet and activate the MultiWay mode with 1024 ways to win. Treasures of Troy has 5 reels, each of which has 4 lines instead of the classic 3. The special symbols of the Treasures of Troy slot are the Wild and the Scatter.

Finn and the Swirly Spin Finn

Finn is a magical elf that can help you have the time of your life. This game is considered one of the best online slots of all time by many players. And for a good reason. We are talking about a slot with 5 reels and up to 243 pay lines, with an attractive RTP of 96.62%, free spins bonus rounds, and much more.

Chicken Plinko

Chicken Plinko by Onlyplay reimagines the classic Plinko concept by mixing arcade gameplay with crash mechanics, delivering fast-paced, humorous action where players drop chickens (or eggs) through peg boards to chase multipliers. With adjustable risk levels, vibrant animations, and a 96.14% RTP, it offers a dynamic experience that balances simplicity, excitement, and crash-style tension.

Elvis Frog in Vegas

This online slot machine has a classic 5x3 structure, but its theme and features are pretty unique. This 25 pay line game comes with an impressive RTP of 96%, wilds, and scatters. If you land a combination of Wild symbols, you will receive up to 500x your bet. One scatter offers you 5 free spins, and the other gives you access to consecutive respins that can trigger the Mega Jackpot.
