Online Slots Guide and Tips

If you plan to play high variance slots, for example, you may need to learn more about RTP percentages and volatility levels. This is especially important if you are new to online gambling.

  • Most people are well aware that there are numerous variations of online slots, so let us introduce you to some of the most popular ones you can expect to find at the casino sites listed on this page. In general, video slots are the most popular type of online casino slots. Following the jackpot slots, they have the highest payouts and are readily available on laptops, desktop computers, and all mobile casino sites.

Different Types of Online Slots

Online slot games are available in a wide range of types, providing both novice and experienced slot players with a plethora of options when it comes to their preferred games:

  • Video Slots
  • Classic Slots
  • Megaways™ Slots
  • Cluster Type Slots
  • Branded Slots
  • Progressive Jackpot Slots
  • Virtual Reality Slots

The following section will go over some more details.

Video slot by Nolimit City - xWays Hoarder

Video Slots

Without a doubt, the most popular type of slots online! They’re taking the industry by storm and show no signs of slowing down. With a wide range of options available online these days, it’s easy to see why they’re proving so popular with players from all walks of life. The majority of the slots you’ll find in online casinos are video slots.

Classic slot by Novomatic - Lord of the Ocean

Classic Slots

This type of slots game has only a few reels and pay lines, providing players with an extremely simple slot experience that gives them exactly what they want from their online casino experience.

Megaways slot by NetEnt - Piggy Riches

Megaways™ Slots

Megaways™ slots, which were introduced by Big Time Gaming, are one of the most popular types of slots machines across all online casinos today, and they are becoming more popular by the day. These games differ from traditional video slots in that they use many smaller symbols on each reel while still providing all of the components you would expect from a video slot machine, such as free bonus spins and random features.

Cluster type slot by Big Time Gaming - Star Clusters

Cluster Type Slots

This grid-style slot format is new to the online slot market, but we believe it will be popular in the coming years. These slots are made up of many small falling squares with various symbols on them. The goal of the game in this slot is to match groups of clusters adjacent to each other on the reels rather than symbols in specific lines across the reels.

Branded slot by Microgaming - Game of Thrones™

Branded Slots

Branded slots are usually top-of-the-line online slot machines. Generally, they involve a famous brand, person, superhero, movie or television series within their game design. Some examples include Terminator 2 or Jurassic Park from Microgaming. Such games are typically provided only by the best slot providers and offer slot fans the chance to win big.

Jackpot slot by Microgaming - Mega Moolah Atlantean Treasures

Progressive Jackpot Slots

Progressive jackpot slots are much like branded video slots since they are provided only by the leading iGaming software companies. Take, for instance, Netent’s Mega Fortune or Microgaming’s Mega Moolah — these are the biggest progressive jackpots in the industry that players can win and are offered to play only at the best online casinos.

Virtual Reality Slots

Virtual reality slots are currently among the most realistic slot games available online. These games provide players with a virtual reality experience through stunning 3D graphics that create a fully immersive environment. To try it out for yourself, all you need is a VR headset and a compatible device.

Real Money Slot Tournaments

A real money slot tournament is a popular type of competition among players of online slot machines. They can play their favourite slot games while also having the chance to win exciting prizes if they reach the top of the leaderboard. The majority of races and tournaments are free to enter, and the prizes are cash, casino bonuses, or extra free spins on selected games. Some slot casinos have gone a step further by offering buy-in races in which players compete for real money and, in most cases, larger prizes than in free races.

These tournaments work as follows:

  • you compete to complete the most spins in a limited time;
  • you score the highest equalized win measured in a bet multiplier;
  • you collect special symbols in the fewest possible spins.

The table below lists some of the best online casinos that offer real money slots tournaments online, as well as the total prize money available.

Try Slots for Fun (Free) Before Playing for Real

Most of the slot sites allow you to play free slots without having to download or register. All you have to do is choose a slot game that you enjoy and play with fun credits. As a result, you will learn the game rules, become acquainted with the pay tables and game mechanics, and gain an understanding of what to expect when you decide to play slots for real money.

  • Keep in mind, however, that any winnings in free play are not real money. If you want to play slots for real money, you must first register at an online casino and make a deposit. The best slot sites always offer a wide range of payment options to their customers, including debit/credit cards, e-wallets, prepaid cards, cryptocurrency, bank transfers, and others, so you should have no trouble making a deposit.

Best Paying Slots: Finding the Right Game for You

An excellent guide to finding the best paying slots is the RTP or return to the player. This is a statistical number on how much a game will pay back over a large sample of spins. Simulations for certification purposes are usually done over billions of spins to determine the average return.

  • In general, the higher the RTP percentage, the more money you can win! Obviously, it can never be 100% because all online slots have a house edge that generates revenue for casino operators and game providers.
  • To get the most bang for your buck, look for slots with high RTPs and avoid those with low RTPs. NetEnt slots, for example, have an RTP ranging from 93 to 98%, whereas Microgaming slots have an RTP ranging from 88 to 98%. And, because an additional percentage is reserved for the jackpot, progressive jackpot games typically have the lowest RTP.

The Difference Between Low Volatility and High Volatility Slots

Nowadays, it is common for game providers to state the RTP of their games. Nonetheless, some companies actually disclose more factual information, such as volatility. You might be wondering what volatility is right now. In simple terms, it is a measure of how wins are distributed across a large sample of spins on a specific slot machine.

  • In general, a low volatility slot will give you more playtime with small wins, whereas a high volatility slot will give you less playtime but more significant big-win potential.
  • Going through the paytable is the best way to determine slot volatility. If the difference in payout between hitting two and five top symbols is significant, the slot is most likely high volatility. The inverse is true for low volatility slot games. The following example shows one of each.
High Variance Slots Developer Max Win
San Quentin Xways Nolimit City 150,000x
Dead or Alive 2 NetEnt 111,111x
CherryPop™ Avatar UX 56386x
Lil’ Devil BTG 100,000x
Money Train 2 Relax Gaming 50,000x
Low Variance Slots Developer Max Win
1429 Uncharted Seas Thunderkick x
Bloodsuckers NetEnt x
Esqueleto Explosivo Thunderkick x

The Best Way to Win at Online Slots

If anyone ever tries to convince you that they can give you the best strategy to play slots, you would be well-advised to avoid these people. It simply does not exist. Online slots are games of chance, where pure luck determines the outcome. Hence, when playing slots, you should not worry about how to win but how not to lose your balance.

⒈ The best we can do is set a budget that we want to spend and adjust the bet size to a number that will give us the playtime we are looking for and play at a risk level we feel comfortable with. If you’ve made some good wins that elevate your balance, you can try increasing your bets; this way, you don’t lose your initial deposit but a portion of your winnings. Remember to start reducing it again if it fails to produce another good win.

⒉ The other tip we experienced players can give is to avoid staying too long in the same slot. We all have our favourites! But we usually have the “false” feeling that we know how the slot behaves, and that big win could be just around to corner.

⒊ If the slot feels “cold,” try a different one and change it again if you get the same bad feeling. Simply avoid “hammering” the same slot in the expectation that it will pay out big at some point.

Bankroll Management When Playing Online Slots

The golden rule is to set a budget for the session or even a single game and stick to it under any circumstances. Determine how much money you can afford to lose, as well as how much you would need to cash out. Whatever the outcome, the game session must come to an end!

Here are some of the reasons:

  • When you get a big win, your natural instinct is to keep betting larger and larger amounts in the hopes of getting that one really big win;
  • If you lose a significant amount of money, your instinct is to keep playing in order to recoup it as soon as possible through additional bets.

Losses and wins can both impair your judgement. The desire to recoup losses, or the euphoria that follows a big win, can easily lead to even bigger losses!

Online Slots to Avoid

After more than two decades of internet existence, we’ve all learned that anything related to money attracts scammers. It is the same with online casino slots and games.

Fortunately, there is a simple way to tell whether an online slot is genuine or a forgery. Simply launch a game in demo mode and proceed as follows:

  1. Right-click on the game window and select “Inspect”;
  2. Once an additional screen appears, choose  “Network” .

Now you should see the server address from which the game loads.

Finding fake online slots server with the Google chrome inspect tool

Each game developer has its own server, and by knowing its name, you can tell whether the one you see is legitimate or not (all properly licenced slot games are hosted on the game provider’s dedicated servers).

Note! If many slots of different game providers
are connected to one server, generally, it is fake!

Online Slots FAQs

Online slots that you enjoy the most will always be the best.

Yes. Most of the online casinos listed on this page offer players the opportunity to try their best online slots for free without requiring registration, however, availability may depend on your country of residence.

Online slots can be played via your mobile device or desktop computer at any time, however, on mobile, there are fewer slots to chose from.

Generally, they are mid or low variance slots, however, for more details, you can check out our slots guide above on how to find the best paying slots.

In a nutshell, the answer is no. Any player who has played slots for a while will be able to tell you a conspiracy theory, a dubious spin sequence or chain of events in their session, or what they consider clear proof of games being rigged. In the player community, this is referred to as wearing a tinfoil hat. Because most, if not all, of our experiences, are subjective and are not based on data or large enough samples.

Here’s an example of a 2019 medium-volatility slot where the developer ran simulations totalling more than 200 billion spins before certification:

  • Big Wins: 15x – 1 in 84
  • Super Big Wins: 40x – 1 in 189
  • Mega Wins: 70x – 1 in 444
  • Epic Wins: 100x – 1 in 997

This is done to collect large enough samples that will supply reliable average data on how a math model of a slot will perform in the long run and make sure the game achieves the advertised RTP (return to player).

You can also see the distribution and frequency of larger wins on the slot machine here. That does not guarantee that you will hit them at those times. Modern online casino slots are based on sophisticated mathematical models. For each spin, an RNG (random number generator) result is called up to determine your spin result. You could spin the reels thousands of times without hitting a super or mega win. Even more so when it comes to an epic win. If Lady Luck is on your side, you could hit them all in a row.


Online slot games should be seen as a form of entertainment that will cost you money. Therefore, you must determine the maximum amount you are willing to spend and never cross that line. Equally important is setting a win limit to get up and walk away instead of squandering it back. You have to remember that you cannot always win, that the house always has an edge and that you can never predict what will happen in a game. If it hasn’t been made clear before, sensible bankroll management really is one of the most important things when playing online slots.
