Play Online Slots for Real Money

Whenever you have familiarized yourself with a certain online slot machine, you have two choices: continue playing for free or start playing for real money. Before you can play online slot machines for real money, you have to register an online casino account at an online casino. However, Pay’n Play Casinos and Crypto Casinos are an exception to this rule. 

At these online casinos, you can start playing your favorite casino game without having to fill in your personal details or anything. Just like any other online casino, you will receive a generous welcome bonus as a new player like free spins or even free bonus money.

Being vivid fans of online casino games ourselves, we know the importance of playing at the right online casino. You want the casino to handle your personal and banking details with care and its customer service to be available 24/7 by live chat or even by phone when possible. Just this reason alone is why we only partner with the best legal online casinos that have valid gaming licenses in place. 

As a player, safety should be your first priority. Think about reliable online payment methods and the safe management of your data. Are you wondering what casino games a certain online casino has available? Simply check out our overview and comparison tables of different online casinos or read our in-depth casino reviews to find out everything. 

As we like honest online casinos as much as you do, we have detailed casino bonus information available on our website. This way you know what you can expect from a certain online casino bonus and what its wagering requirements are. We have also enlisted all the online slots with the highest RTP for you. 

What is RTP?

Whenever you want to play an online slot machine, you should check out its RTP first. RTP is an abbreviation of Return to Player. This is a percentage that shows you how much you will receive back in the form of winnings from a certain slot. If a slot machine has an RTP of 96%, it means you will receive $0,96 in winnings for every $1 you wager. This return to player percentage is calculated over thousands, if not millions of spins. For this reason, the results of a certain slot session can vary. 

Free online slotsThe RTP of Online Slot Machines vs. Land-based Slot Machines

The average RTP of online slots at legal online casinos is about 95%. There are online slot machines with an RTP of 98% and even 99%, but also with mediocre return to player percentages of about 93%. Most of the times, these slot machines have a built-in progressive jackpot. This means that although your average expected wins are a bit smaller, you do have the chance to win life-changing amounts of money. These types of slots are called progressive jackpot slots

The return to player percentages of online slots are generally higher than those of land-based or physical slot machines. The reason for this is because land-based slots don’t have to have as high RTPs by law. We cannot tell you the exact RTP percentages of physical slot machines because this varies per country or state. Another reason why online slots pay better than physical slots is because online casinos don’t have as many operational costs compared to a real land-based casino.

The Features of Online Slots

Online slots have a whole lot more features compared to physical slots. Not only do they have stunning graphics and epic soundtracks, they also have added gameplay features that are virtually unseen at offline slots. The possibilities are endless, from near-infinite paylines to walking wilds, and even expanding reels. 

Below we will highlight the most popular and common online slot machine features so you know exactly what they do and what you can expect by triggering certain special symbols.

Wild Symbols

You can see wild symbols as a sort of joker symbol. They increase your chances of winning because they can substitute any other symbol. Wild symbols usually transform into the highest-paying symbol or into a symbol needed to form a winning combination on one of the pay lines of an online slot machine. 

Let’s say you have two 7 symbols and just need one more to trigger a payout. In this case, a wild symbol will substitute for a third 7 symbol, causing you to win. However, in most cases, wild symbols cannot transform into jackpot, free spins, or scatter symbols. Almost every modern online video slot has wild symbols and even classic retro slots have them.

Walking wild slotsWalking Wilds

Walking Wilds are a new form of wilds that you will encounter on some of the latest online slots and on NetEnt slots in particular. Walking wilds provide players with a higher chance of getting a winning combination. Whenever a Walking Wild symbol shows up on your screen, it will move one spot to the left or right every following spin. In most cases, this next spin is totally free and practically a free spin, at Jack and the Beanstalk for example. 

The walking wilds are called walking wilds because they sort of ‘’walk’’ across the playing field rather than ‘falling’ or ‘spinning’. When the walking wild symbol moves out of vision, everything turns back to normal and the base game starts again. Not a huge fan of Jack and the Beanstalk? Then you might like the Narcos slot, Halloween Jack, or Creature from the Black Lagoon instead.


Stacked wilds slots

Stacked Wilds

Stacked Wilds must be our favorite type of wilds! They are a bit rarer compared to Scatter Symbols and regular wilds, though. With a Stacked Wild, you have more chances of winning than a regular wild symbol because a Stacked Wild will fill an entire reel with wilds instead of just a single spot on the playing field. One of the most popular online slots with stacked wilds are 2 Dragons and the Game of Thrones slot.

Sticky wilds slots

Sticky Wilds

Sticky Wilds do exactly as they say on the tin. Whenever you get to spin some Sticky wilds, they will stick on your screen for a couple of spins. Every consecutive spin, the sticky wilds act as regular wilds and help you get winning combinations more easily. Some of the most beloved slots with sticky wilds are the Dead or Alive 2 slot by NetEnt and Hellboy by Microgaming.


Expanding wilds slotsExpanding Wilds

Expanding Wilds are wild symbols that expand so that they cover more than just one spot on the playing field. There are 2×2 expanding wilds, but also 3×3, and even ones with 5×5 size. The expanding wilds can substitute every other symbol as per usual, except Scatter Symbols. Because there will be many wilds on the playing field, your chances of winning are greatly increased whenever you get big expanding wilds. 

Expanding wilds can show up randomly on the reels, but you cannot influence where they appear in most cases. With some online slot machines, expanding wilds can only show up on specific reels. It could be the case that expanding wilds only show up on reels 2, 3, and 4, for example. Some of the most popular online slots featuring expanding wilds are Hall of Gods by NetEnt and Wild Blood by Play’n GO.


Wild reels slots

Wild Reels

Wild Reels are a bit similar to Stacked Wilds: instead of a single square, an entire reel gets filled with wild symbols. The beauty of Wild Reels is that the player can trigger multiple at the same time. If you happen to spin more than one reel full of wilds, you’re in for a big win!

Multiplying reels slots

Multiplying Wilds

Multiplying Wilds gives traditional Wild Symbols a unique twist. This type of wild actually doesn’t need any additional explanation: it is just a regular wild, but a bit better as it adds a multiplier to your current payout as well. You will find Multiplying Wilds in casino games like Thunderstruck II and during certain free spins bonus rounds, for example at the popular NetEnt slot Dead or Alive 2.

Online Slot Machines Bonus Features

Bonus features can trigger a prize and generate more action on the reels. Below we will discuss the seven bonus features that you will come across the most whilst playing online slot machines. One of the most favorite bonus features of video slots among casino players is without a doubt free spins

The Bonus Buy Feature is another great feature, especially for those players with a little less patience: for a certain amount of money you can buy a bonus feature directly without having to spin endlessly, hoping to trigger one. Examples of very popular Bonus Buy Slots are Money Train 2, Remember Gulag, and the Megaways slot Extra Chili.

Re-spin slots


Re-spins allow you to win extra money. Re-spins look a lot like free spins, but the difference is that re-spins trigger more often compared to free spins. To activate free spins, you often need to accumulate a certain amount of scatter symbols. A re-spin can trigger at any random moment without having to spin specific symbols. There are a lot of online slot machines with re-spins and some even offer players the opportunity to trigger multiple free re-spins. The most popular online video slots with re-spins are Starburst and Reel Rush, both from the famous casino software provider NetEnt.

Free spins slots

Free Spins Feature

This feature is a bit self-explanatory. Whenever you get to trigger free spins, you will receive a certain amount of spins totally free of charge. Sometimes you will also activate a bonus game when you trigger free spins. In most cases, you can earn more free spins when more free spins symbols show up on the reels. For instance, 3 symbols trigger 10 free spins, 4 symbols trigger 20 free spins, etc. With most online slot machines, free spins are triggered by spinning Scatter Symbols.

Pick and win slots

Pick & Win Bonus

The Pick & Win Bonus is a bonus feature that can be triggered by activating a bonus game. A good example is Blood Suckers by NetEnt, where you get to choose from 12 closed coffins during the bonus game. Each coffin contains either a fixed cash amount or nothing at all. You get to open coffins until you open one with nothing in it. When this happens, the bonus game ends.

Bonus wheels slots

Bonus Wheels

We at assume everyone is familiar with the Wheel of Fortune, right? The bonus wheel feature actually works exactly the same. Whilst playing some online slots, a bonus wheel can appear. On this wheel there will be several prizes you can win, from multipliers to free spins. An example of an online slot with bonus wheel feature is Microgaming’s Mega Moolah or NetEnts Gonzo’s Quest.

Super meter slots

Super Meter

The Super Meter is a bonus feature that appears mostly on classic retro slots. With this feature, the player can risk their winnings or a part of their winnings to have a chance of winning bigger during the next spin(s). This is a great feature for the risk-takers among us who like to take a gamble every now and then. One of the most famous classic slots that feature a Super Meter is Super Jesters 200.000

boss battle slots


Boss Battles

Boss Battles, also known as Beat the Boss, is a bonus feature where the player has to face a boss similar to a normal computer or console game. When the player succeeds in beating the end boss, the player will receive a multiplier, free spins, or a cash bonus. One of the most popular slots with a Boss Battle feature is the Battle Royale slot


Bonus buy slots

Bonus Buy

Whenever you don’t want to spin endlessly to trigger a bonus, you’ll be happy to hear that there are slots that allow you to buy a bonus instantly, known as bonus buy slots. For a certain fee, you get to trigger the bonus instantly. Examples of online video slots with bonus buy features are Remember Gulag and Sweet Bonanza

Casino Bonus Terms 

Most casinos warmly welcome new players with a welcome bonus and almost every casino rewards its players for their loyalty with recurring bonuses such as reload bonuses, free spins, cashback bonuses, and even no deposit bonuses. Note that almost every online casino bonus comes with certain bonus terms. 

These terms, often called wagering requirements, have to be fulfilled by the player in order to be able to withdraw any winnings to his or her bank account or e-wallets such as PayPal, Neteller, or Skrill. If you don’t know what the exact bonus terms and conditions of a certain casino bonus are, feel free to ask us or the customer service of the online casino you’re playing at.

How to Deposit and Withdraw Money at Online Casinos?

At most online casinos, you can easily deposit money from your bank account by wire transfer. Most casinos also accept credit card deposits made by Visa or MasterCard. Other online gambling websites also accept e-wallet deposits such as PayPal, Neteller, and Skrill. There are even crypto casinos that take Bitcoin, Ethereum, Litecoin, and Dogecoin deposits. All online casinos have different deposit and withdrawal policies and limits, so be sure to check those out in our extensive, honest, and unbiased online casino reviews.

What Types of Slot Machines are there?

Nowadays there are many types of slot machines and they literally come in all sorts and sizes. New online slots are released on a monthly basis by the world’s best casino software providers. There are classic retro slots, but also themed slots like Ancient Egypt slots, Viking Slots, Fairy Tale slots, etc. Even movie-themed slots like Iron Man 2, and The Godfather, music band-themed slots like Guns N’ Roses, and Netflix series-themed slots like Narcos exist. All these types of slot machines can be played for free on our website or for real money at one of our licensed partner casinos.

?Jackpot Slots

Jackpot slots are insanely popular nowadays and for a good reason. Everyone wants to win life-changing amounts of money, right? There are basically two types of jackpot slots: progressive jackpot slots and non-progressive jackpot slots. Progressive jackpot slots obviously have higher jackpots. These jackpots are filled by every player playing them. A tiny part of every wager gets added to the jackpot to be won until one lucky player wins it. Slot machines with non-progressive jackpots use fixed jackpot amounts instead. In some cases, there are multiple jackpots to be won such as minor, midi, major, and mega jackpots. The most popular progressive jackpot game across casino players globally is Microgaming’s Mega Moolah jackpot slot.

?Live Casino Games

Although we focus mostly on slot machines on our site, we know many players also love to play live casino games or live dealer games from time to time. Live casino games are a special kind of casino game, where you truly get to experience the feeling of being and playing in an actual casino. These games are presented by real live dealers and the best thing is that you can play them from the comfort of your own home. Examples of live dealer games are live roulette, live blackjack, and live blackjack.

?Modern Video Slots

Modern video slots are feature-packed to the brim! This makes them a whole lot more exciting, as you can receive free spins or trigger bonus games. Good examples of modern video slots are Bonanza Megaways and the ever-so-popular Starburst by NetEnt. Have you never played slot machines before? Then we definitely recommend trying classic slots first, as they don’t have all these features, making them a bit easier to understand.

?Classic Slots

Classic slots are slot machines as you might remember them from your local pub or cafeteria. These games are very easy to understand and usually just have 3 reels and a single pay line. Don’t expect too many bonus features on these types of slots, though. A lot of players love nostalgic slots like Simply Wild and Club 2000, so why don’t you check them out for free?

?Mobile Slots

Nowadays most casino software providers have optimized their games for mobile gameplay. Their games are coded in HTML5 and fully responsive, which means they automatically adjust to the screen size of your mobile device. Some casino software developers went a step further and even developed mobile-only slots with portrait mode and battery lifetime-saving features.  

?Themed Slots

Although classic slots rely mostly on their nostalgic appearance, modern slots are packed with features like free spins, bonus games, and other special built-in mechanisms. Each player is different. You might like Ancient Egyptian-themed slots or Viking slots. For this reason, we have made different sections on our slot machines website covering each theme in detail.
