Online Slots

The average casino offers hundreds of games. The majority of the offer consists of online slots, which are considered as the standard casino game. This is not surprising; online slots are the way to gamble directly with real money, they are easy to play, and the number of slots is enormous.

New slot machines, older slots, classic slot machines, and jackpot slots. The list of titles is overwhelming; therefore, finding the right game can be a drama when you don’t know the name. But what about those online slots, and what do you really need to know before you start playing?

What are online slots?

Online slots are games in which symbols on different reels give a random outcome on every spin. To set the slots in motion, determine the odds, and click on “Spin.” The reels move, and when they come to a stop, the profit or loss is realized.

That sounds simple, but playing on slots is no longer that easy. There are more exceptions today on all those standard slot machines. This is why it’s good to first have a look at the conditions before you start playing. We usually choose to play for free a few times before we play for real money.

In this way, you can not only see how the slot machine works, but you can also see whether it’s a slot machine that you want to play with real money. Because let’s be honest, not all slots are the same.

Online Slot Providers

 Online casinos offer numerous slot machines, but it’s not the casino itself that creates these online slots. Software developers all over the world are producing the slots. Well-known names in the industry include:

  • Net Entertainment
  • Microgaming
  • Playtech
  • Play ‘N Go
  • Betsoft
  • NextGen Gaming
  • NYX Gaming
  • Yggdrasil
  • ANY Gaming

The list of software developers is much longer. It is estimated that there are more than 100 companies that work on new slots every week.

These software developers create the games. When a casino wants to offer certain games to their players, they have to purchase a license. These licenses can cost thousands of dollars, depending on the quality and popularity of the games.

Not all casinos can offer all popular games. After all, this is far too expensive, and a selection must be made from the providers. If you want to know more about this, take a look at our casino reviews.

How many slots are there?

It is impossible to calculate how many slots there are. Not all slots from all developers are registered, and new games are created daily. Probably the number of slots would be somewhere in the thousands.

No casino can offer all slot machines. Besides, the costs there’s simply no room for it. But this isn’t a bad thing because there many outdated and low-quality slots that nobody wants to play anymore. However, few software developers remove slots. In fact, it shocked some casinos when developer Net Entertainment decided to take down some titles.

Usually, only new games are added. And that ensures that the number of online slots continues to increase.

What are the differences between slot machines?

Many people complain that all the games are very similar. But not all slots are created equally. For example, put the online fruit slots next to the new online slots from developers such as Net Entertainment. The essence of the game is mostly the same because else the games could not be classified as slot machines. There are reels with symbols on all slots, and the outcome is determined by an RNG (Random Number Generator). But it also ends there, because there are more differences than similarities.

The differences and similarities

It is not easy to keep all types of slots apart. That’s why we made an overview of several prominent variations. In this way, it becomes a little easier to find a slot machine that you would like to play.

Old slots, a bit of nostalgia
Old online slots are the slots that are very similar to the offline slots that you used to find in arcades, cafes, and cafeterias. Simbat is one of the most famous developers in this field. These slots are often referred to in the casino as “classic slots.”

The classic slot machines are often simple and consist of two parts. The bottom part is the place where you start playing with a credit (coin). If you have made a profit, the profit goes to the club meter. You can then go to the top game when you have collected enough credits on the meter. The top game is played with more pay lines and offers higher wins. If you do not have enough credits to continue playing here, you have to go back to the bottom game.

Online fruit slots

Unfortunately, slot machines are often thought to be old slot machines by definition. That’s not correct, many developers regularly release slots with fruit symbols on the wheels. These slots can be inspired by the old slots, but that is not always the case.

In the online casino, you can find many slot machines where fruit symbols have the leading role, but also include various features such as free spins or bonus games. If you see a slot with fruit symbols (grapes, cherries, strawberries, melons, and more), this does not always mean that it’s an old slot.

New Online Slots

New online slots made by modern software developers don’t even look like the old slots anymore. They look more like complete video games in which the graphic elements are very high quality. These slots often have different functions and features. You can think of:

  • Wild symbols;
  • Random features, not related to certain combinations;
  • Bonus games in the game itself;
  • Bonus games in another screen;
  • Free spins;
  • Additional elements outside of the slot machine wheels.

These unique features make new online slots particularly attractive for most players. Classic slot machines lovers will immediately walk away when they see such features.

If you like to play slots like the old machines from the past, then the latest video slots are not recommended. Are you looking for games that use all technologies and that are graphically similar to a video game? Then it is definitely worth looking at these games.

Jackpot slots

The last category that we definitely want to mention is the category where dreams come true. Jackpot slots are a real hype at the moment. Online slots are played worldwide, which causes more and more gamblers are playing these games. What happens when you place a progressive jackpot on a slot machine that is offered in casinos worldwide?

Right, you get millions of winnings and jackpots that keep increasing in value as you play. The quality, functions, and graphics of jackpot slots differ widely. Below are some of the most popular online jackpot slots that you can play in some of the better casinos:

  • Mega Moolah
  • Mega Fortune
  • Mega Fortune Dreams
  • Arabian Nights
  • Hall of Gods
  • Rango
  • Major Millions
  • King Cashalot

Jackpot slots often are not free to try out. NetEnt jackpot slots are an exception to this, as they can always be played for free before playing with real money.

What should I pay attention to?

Playing online slots is fun when you find the right slots that suit you, and when you find a provider with fun promotions. Here are some useful things to know before you start playing slots:

Bet level with online slots
Each slot machine has its own betting options. Usually, you play with a specific coin value that you can adjust before you start playing. It’s good to pay attention to this because slots are not set up standard on the lowest bet when you open the game.

NetEnt slot machines often have a two-part betting method. On one side, you have a coin value that you can set, and on the other hand, you work with a bet level. That way, you have even more options to adjust your bets.

Slots can often be played for a few cents per spin. The maximum bet depends very much on the developer and the game. Often you will face a maximum bet of $50, but there are also slots where you can bet more than $200 at once.

When you play with multiple pay lines, this means a higher bet. If you play with a coin value of one euro and you have ten pay lines, the total bet is $10. Therefore, do not look at the coin value before you spin, but look at the total bet per spin. This must always be stated at the bottom of the slot during playing.

Possible bonus play and/or free spin
Slots are fascinating when you know what can happen. Therefore, first look at the information on the slot machine itself (usually indicated with an “i” or “paytable”). What exactly do you need to get on the wheels to unlock a bonus game? When do you unlock the free spins, and what about any extra features on the slot machine? If you know what to pay attention to what the possibilities are, then playing online slots is usually a lot more exciting!

Online slots and payout, how about that?

Slots generally pay out around 95%. This means that on average (over 1000 spins or more), you must have recovered 95% of your total stake. The rest, of course, goes to the casino. However, it’s not the case that all slots have the same percentage. You can compare slots to play the best paying slot (BloodSuckers from NetEnt). Whether it is worth playing like this is still the question. A more beautiful slot machine with a less percentage payout can be more attractive to play for a longer time.

Online slots pay much better than offline slots. Online slots in casinos that are regulated in Malta must payout at least 92%. For comparison: at landbased casinos, this is only 82%. And in Las Vegas, the payout percentage is around 75%. Clearly, the house has many more advantages there.

The slot machines in licensed casinos are also regularly checked to see if the payout percentages are fair and correct.

Play for free

Because there are so many different slots on the internet, it’s challenging to find a game. Fortunately, there is a solution: play free slots. Most of the time this is a possibility and sometimes even without creating an account.

Playing free slots is, of course, not as exciting as with playing real money. However, it makes it possible to take a quick look at the structure of the games. If you feel that you really like a specific slot, you can decide for yourself whether to continue playing for free or whether you are trying to get a nice profit with real money.

Play online slots on Android or iOS, is that possible?
In almost all cases, they have adjusted the software, so games are compatible with multiple platforms like Android and iOS. Winvio actually no longer lists any casino that is not suitable for mobile players. Of course, you will find this info in all of our casino reviews, so you immediately know whether you can play on your mobile.

Nowadays, it’s standard that new online slots are made immediately suitable for mobile players. Because of the simple reason that there are more mobile games at the moment.

Best casinos to play

Are you a fan of a particular software developer? Do you like to play jackpot slots all evening, or do you want the broadest possible range with new slots? That is definitely something to take into account when choosing a casino.

All casinos have many slots, but the selection of slots is not always the same. Are you looking for a casino to play online slots, then it’s wise to first look at the offer before creating an account.

Casino promotions on slot machines

Don’t you have an account yet in an online casino, and are you looking for fun slots to play? Don’t forget to take a look at the welcome bonuses. Many providers give free spins to new players. These free spins can only be used on slot machines (not on baccarat or online roulette). The bonuses always have specific conditions, but at the same time, they are an excellent way to make a nice profit.

It is smart to look at the offer before creating an account. Take a look at the casino reviews on our site to you to know what to look out for.
