Best slot machines online in 2022

There are as many opinions as there are slot machines online. What is certain is that some are more popular than others. Although the preferences of USA players vary, some classics and newcomers receive extra attention. Others get a few favorites that they easily fall back on after trying new and modern video slots.

We have talked to our recommended USA casinos online and compared their statistics with the number of Google searches each month on the different slot machines and composed a list of the best online slot machines. In that list you will find games from NetEnt, Play'n Go, Microgaming and Thunderkick.

1. Starburst – NetEnt

Starburst is an old classic with simple mechanics. It is referred to as the clearest star in the casino sky due to its popularity among USA players. Neither maximum benefit, volatility nor RTP are groundbreaking on this slot machine, but what role does it play when it is obviously so popular. One trait Starburst has is that you can win both ways, which captures the attention of the player and makes it more interesting. It also has re-spins and expanding wilds.

  • Volatility: Low
  • RTP: 96.09%

2. Jackpot 6000, NetEnt

With the Jackpot 6000, NetEnt also gets off with 2nd place among the best USA slot machines. This classic vending machine belongs to the past, but remains part of the future of countless USA online casinos. Both volatility and RTP are high, making the potential great and the joy of gain even greater. With well -known and dear casino symbols, this slot machine has won the heart of thousands of USAs.

  • Volatility: High
  • RTP: 98.90%

3. Sweet Bonanza, Pragmatic Play

In 3rd place in the ranking we find a more playful and sugary slot machine than the first two. Sweet Bonanza from Pragmatic Play has been a few years old, even though it feels like it just came out. The game grows in popularity for each month that runs due to its extremely high volatility that produces YouTube moments in a row. In this USA slot machine, the bonus round is the big and in many online casinos you can buy right into it.

  • Volatility: High
  • RTP: 96.48%

4. Book of Dead, Play’N GO

We will not go back many years before we find Book of Dead first in all such rankings around the world. But the world is moving forward and unfortunately for this casinosity it means that new games are taking over. It is nevertheless the fourth most popular in USA, which means 2000-5000 players each month. The Book of Dead combines a fairly high potential in the basic game with a huge potential in the bonus round, which has led many to have been seduced by Rich Wilde over the years.

  • Volatility: High
  • RTP: 94.25%

5. Fire Joker, Play’N GO

There will be fiery in the casino classic Fire Joker from Play'n Go. The wheels catch fire when Wilds lands randomly on one of the 3 wheels and forms winning combinations, while USA players across the country enjoy high potential and endless tension. Four Joker sneaked into the top charts many years ago and still seems to set fire to the moods of many.

  • Volatility: Medium
  • RTP: 94.23%

Slot machines on mobile

In recent years, the requirement for technology in slot machines has increased sharply. Before, most people had to log in to PC to play slot machines online. Now the technology has come so far that most people play slot machines on mobile.

All USA casinos online offer games on mobile. The games have become responsive and have menus well adapted to both iPhone and Android screens. In addition, the casinos have worked extensively with technology that improves the mobile experience. This applies, among other things, to speed on the page, how long it spends loading and navigation. Below you will find a small overview of the very best online casinos for people who like slot machines on mobile.

Volatility in USA slot machines online

Volatility is a debated topic and there are many preferences among USA players. Some prefer high volatility, while others want it as low as possible. You have certainly seen overviews of the best USA slot machines where some of the information is about volatility.

But what is it and why is it so important? Volatility controls how often and how much you can win at a slot machine. Some casino games rarely pay, but produce bigger winnings and others will pay less winnings much more often.

A high volatility slot machine will pay rare, but at the same time have the potential to pay out the biggest gains. As a result, you can get many dead spins or spins without gain in anticipation of anything bigger. Such slot machines can quickly empty your casino balance.

Low volatility slot machines will be perceived as more generous because they pay more often. You will still experience spins without gain, but not so many and the prizes will generally be better distributed. These games rarely have a great maximum benefit, but there are also exceptions from this rule.

What is RTP and how does it affect a slot machine?

RTP stands for Theoretical Return to Player and means a refund percentage in USA. RTP is a difficult topic with many misunderstandings and myths. Unfortunately, even experienced casino players misunderstand how this works and it leads to unrealistic expectations of slot machines and classic table games.

Here at Byteballjs we know exactly what RTP is and how it works and now we will clean up all the misunderstandings once and for all. The first myth to be revealed is that RTP is not personal, related to a player or to a great extent gives some good indication of how much you can expect to win back.

The repayment rate is calculated over billions of spins and indicates how much a slot machine will on average repay the total bet over 1 billion spin. This means that for every billion spin, an average of a percentage rate will be paid out in prizes distributed to all players who have played the game all over the world.

Of course, this can be used as an indication of how well a slot machine pays out, but because we as casino players are such a small part of the basis, volatility and maximum gain will be a better guideline when playing in a casino online.

How to win on slot machines

Ever since the first slab bandy saw the light of day until today, new ways of winning in slot machines have emerged. In recent years this has exploded and in this section A of our article on USA slot machines online we will go through how you win.


Pray lines are a popular way to win in a slot machine. The mechanics are simple and this was used in the first slot machines. Walking lines are lines on a slot machine where the goal is to get so many symbols to hit continuously on this line from left to right. In recent times they have also made slot machines where you can win both ways. Often there are requirements for 3 equal, continuous symbols on the same line before you win.

Ways to win

Ways to win has similarities to paylines, but must not be confused. While the symbols are required to hit a specific line in a slot machine with paylines, a game with Ways to Win will only require that you have one specific symbol of each of the three wheels farthest to the left. This means that you often get far more ways to win in such a vending machine.


Megaways are the extreme variant of "Ways to win". Here, the number of ways of winning will vary for each spin, either by the symbols having different sizes or the game surface expanding so that it can accommodate more symbols. While in Ways to Win often wins 256 ways to win, you will be able to get over 100,000 ways to win in a megaway slot machine.


Cluster has rejected the idea of collecting symbols from left to right or having to be in line. Cluster pay means you need a certain number of symbols to each other anywhere on the slot machine. Often this is the number of five symbols. Example of such games are Jammin 'Jars and Reactoonz
