Play Online Slots

slots online

Online slots have been around since the 1990s and have seen major evolutions, from the classic slot to the modern video slot. Another reason for its popularity is undoubtedly the free slots that you can find. Almost all online casinos give you the chance to spin on a slot machine for free before taking a gamble with real money. In addition, they also give you bonus money for all games. We discuss the main slot machine types here.

Types of slot machines

Slots come in all shapes and sizes. While they started out with 3 reels and a single payline, nowadays there are seemingly no limits to the range of games available. From traditional slot machines to the most innovative, cutting-edge games with thousands of paylines, exciting features and excellent graphics, you can play them all online. In the next section you will find an overview of all the different types of online slot machines that you can play on.

Online Slots VISA

Slots remain the number 1 hit at all online casinos. Most visitors are interested in the new slots or the most popular slot machines . There are many payment methods to use, but VISA remains the number 1 here. In terms of security and processing speed, they far exceed the competition. Nowadays they also have a good bonus in combination with the right casinos. We have prepared for you the best casinos with online slots VISA so that you only have to worry about choosing from the popular games.

Fruit machines

A fruit machine or fruit slot is a classic type of slot machine. Slot machines are usually found in cafes and arcades in Australia and have more features than a traditional slot machine. Such slots can include gambling features, bonus routes and hi-lo cash ladders, meaning they require more player interaction than a classic slot. Other typical features include hold and nudge options.

Classic slots

When we talk about the classic slots in the online casino, we don't mean the old-fashioned bins of the 80s. They are the simple slots that you found in online casinos in the early 2000s. Usually they have 1 payline and 3 reels. But many online slots are also called classic slots because they mimic the style and simplicity of older slots (read more about 80 's slots and 90 's slots ).

Slots have a long history. From classic slots and fruit machines , old slots from Club 2000 to the modern progressive jackpots from NetEnt, the slot is one of the most diverse and popular casino games. Whether you play online, in an arcade or in a physical casino. Where everything used to be mechanical, today the entire gambling process has been digitized.

While physical slots used to only have fruit symbols and sevens, nowadays there are slots with incredibly different themes. Yet old games are still popular, both with collectors who buy them second-hand, and with casino players who still enjoy playing them. In this article we will let you know all about the history of different slots and how this game came about.

Slots Club 2000

Due to the great popularity of this game, game designer Simbat Entertainment has decided to also market an online slot. The game offers all the game features of the classic slot machine, but has one extra. You can play two games at the same time. This of course gives you double chances of winning. Here too you can win 200 times your bet and the whole thing looks almost the same online. Club 2000 slots featured 3 reels with a single payline, which is typical of old slots . You also found the typical fruit symbols that you find in most old slots. It was a physical slot full of cherries, grapes, melons, lemons, oranges, plums, strawberries and bubbles. But it also had some special symbols like stars, a four-leaf clover and the logo of the famous Club 2000 slots as scatter.

Video slots

Where and when we should draw the line between classic slots and modern video slots is not clear. The development of old-fashioned, slow games to modern slots without Flash player such as Guns'n Roses from NetEnt, Vikings Saga from Yggdrasil or Book of Dead from Play'n Go has been gradual. After all, every year slots get better graphics, more animations, creative bonus games and other crazy game features. Nowadays there are even 3D slots so we will never know where the evolution ends.

Modern video slots; usually they have multiple paylines and 5 reels. You will find plenty of bonus features such as free spins and bonus games. In addition, they usually have a free play so that you can try the game for free.

Jackpot slots

Jackpot slots exist in modern and classic jackpot variants. A jackpot is a large amount of money that you can win as a prize. Several high stakes slots also have a progressive jackpot that can run into the millions. The highest amount ever won with a progressive jackpot is over 17 million euros!

243 way slots

243 ways slots replace the standard paylines with different ways to make winning symbol combinations. In such slots, winning combinations are created by placing the same symbols anywhere on adjacent reels, starting from the leftmost one. During each round, there are 243 ways to win, based on all possible symbol combinations. These games have 5 reels and 3 rows. You cannot adjust the number of ways to win when playing 243-way slots.

No deposit slot machines

No deposit slots bonuses can be found at online casinos. It allows you to play and win real money on slots without having to make a deposit. Such offers may consist of free play money or free spins. You can also play online slots for free at many casino sites without making a deposit.

No registration slots

At a casino without registration you can play free slots without having to create a player account. While many casino sites offer free demo slots, most casinos require you to sign up to play the free slots.

Bonus slots

Bonus rounds are a big draw of slots. They are usually unlocked by spinning a certain combination of special symbols. Bonus features add to the thrill of playing slots as they can reward you with big cash prizes. The best online slots with bonus rounds are so popular with players due to the extra fun and involvement they add to the overall gaming experience.

Branded slots

Branded slots are licensed games based on TV shows, movies, celebrities and other pop culture themes. They have proved very popular with the players. These games feature authentically themed symbols and creative, exciting brand-related bonuses and features. Among the most popular branded slots you will find Game of Thrones, Guns N' Roses and Gladiator.

Bitcoin slots

Bitcoin slots are quickly gaining popularity with players who appreciate the security and anonymity that comes with depositing with the cryptocurrency. Bitcoin is not widely accepted in slots. Still, more operators are starting to support the payment method. The top Bitcoin casinos have a wide variety of slots to choose from. The highest paying ones are those of the slot adventure type.

PayPal slots

PayPal slots casinos allow you to play online for real money with the added layer of safety and security that the e-wallet provides. The best casino sites that accept PayPal have a rich and diverse selection of games. You can play video, 3D, progressive, classic and other types of slots with the added peace of mind that your financial information is protected.

Penny slots

Penny slots allow you to play a classic slot machine for just a penny per payline. Most slots offer adjustable coin values, so you can choose the bet that suits your budget. Many have multiple paylines, so in most cases it costs more than 1 cent per round to play with all betlines. You can play slots online for free on 1 cent.

High stakes slots

High stakes slots are suitable for high stakes players and experienced high rollers. Some high stakes slots have relatively high minimum bets. Others offer adjustable coin values that allow you to wager up to hundreds or thousands of Euros per round. Playing high stakes slots offers the opportunity to win big payouts.

Megaways slots

Megaways is an invention of Australian software developer Big Time Gaming, which has received nothing but glowing player reviews since its launch in 2015. There are a number of different themes and styles that really make Megaways slots stand out. The games are a unique twist on traditional slots, with thousands of ways to win each round. These games contain a 'random reel modifier', which causes the number of symbols to change randomly during a round. This allows many different types of patterns and symbols to be displayed.

Megaclusters slots

At first glance, slots using the Megaclusters mechanism are very similar to the standard cluster plays slot. In these standard cluster pay games you create a winning combination by getting a cluster of matching symbols. These clusters usually consist of symbols that appear next to each other vertically, horizontally and sometimes diagonally. The larger your cluster of matching symbols, the better the potential reward.

When a winning cluster is created, a 'reaction' takes place and the successful symbols are removed from the playing field. It's here that things are slightly different and have the potential to get a lot more exciting. Instead of being replaced by a single symbol falling down, each winning symbol is replaced by 4 smaller symbols. This offers even more possibilities to create an enlarged winning combination. If these new symbols land a win, more small symbols drop down from the top of the reels and the process repeats. The 'reactions' continue until no more new profits are formed. The format is super simple, but the shape-shifting game grid can make for some spectacular action.

WowPot slots

The WowPot slots are inextricably linked to a particular panel of games. In general, the WowPot format jackpots are interrelated. Each time a player places a bet, a fraction of their bet is used to fund a community jackpot, also known as a pot.

The total of the WowPot jackpots can easily run high as thousands of players contribute to its supply. When playing this game format you will notice that the jackpot amount is always displayed above your screen. The essence of the mechanism consists of different types of jackpots that you can unlock once you start betting on one of the games of the format.

Drops & Wins slots

Drops and Wins slots are a fantastic opportunity to get cash bonuses when playing your favorite slot machine. They can appear at any time, in any casino, on all selected slots.

The Drop & Win promotions are of course the ones with the biggest jackpots. The bigger the jackpot, the higher the thrill. Daily, weekly or monthly recurring Drop & Wins are also great as you can plan ahead and know when to start playing to increase your chances of winning big jackpots.

Bonus Buy slots

Bonus Buy slots is a category of online slots that have a buy feature option. Every online slot here has a demo. You can simply pay a certain amount and, for example, immediately enter the free spins rounds. You can also play the bonus bet slots with slightly higher bets per round but higher chances of winning or getting the in-game bonuses.

How do you play slots?

If you like slots and you want to try them out for free, there are several fun ways to do so. Slots are by far the easiest games to play in an online casino. No skill is required. You just press the spin button and hope you get lucky with a winning combination.

Online Slots symbols

The variety of symbols on a slot machine differs from game to game. There are certain types of symbols that are common in slots, such as playing cards and fruits. Others are adapted to the theme of the game. But not only the appearance and design of the symbols vary, also their function. There is a series of special symbols that have specific functions. Some replace others, some activate special features, some increase your winnings. If you want to know what symbols you will find when playing online slots, free slots give you a taste of what to expect. Below you will find out more about all the different types of symbols that you will find in slots and how online slots work.

  • Standard Symbol – you can see all standard symbols and their payouts on the slot's paytable. The more symbols that land on an enabled payline, the bigger the payout. Normally playing card symbols offer lower payouts. The higher value symbols are often designed to reflect the theme of the game.
  • Scatter – scatter symbols can land in any position on the reels. Scatter payouts usually reward you with a payout multiplied by your total bet, unlike standard symbol payouts, which are only multiplied by your line bet. In many online slots, these symbols are the key to triggering free spins or bonus rounds.
  • Multiplier – these symbols multiply a standard payout by a certain amount. A multiplier can be a standard symbol and increases the payout of a winning combo. Some wild symbols also act as multipliers and can increase the payout of any winning combination they fall into.
  • Bonus Symbol – Bonus symbols are the key to unlocking bonus rounds. They often work similarly to scatters in that they don't all have to appear on the same payline to trigger the feature. Bonus symbols usually reflect the theme of the game.
  • Free Spins symbol – while scatter symbols often trigger free spins on a slot, some games have an extra special symbol that can trigger the free spins feature. These must appear in a random position in some games, or on an active payline in others.
  • Wilds – common in slots, wild symbols act as a joker and can substitute for other symbols to complete winning symbol combinations. In most cases, the wild symbol replaces all standard symbols, but not the bonus, free spins or scatter symbols.
  • Sticky Wilds – this type of symbol is an improved version of the classic wild symbol. Sticky Wilds hold their position on the reels for a certain number of re-spins. This increases your chances of winning during the next re-spin(s).
  • Stacked Wilds – a stacked wild is basically a series of wild symbols appearing in consecutive positions on a reel. Stacked wilds can appear as a larger symbol that can cover an entire reel, or they can take the form of numerous regular wild symbols in a row.
  • Expanding Wilds – such symbols replace others, such as a standard wild symbol. However, the symbol expands as it lands in more places. They usually expand vertically to fill entire reels, and in some cases can expand horizontally across several rows.
  • Cascading Wilds – when a wild symbol lands on a reel, it disappears, along with all other symbols in the winning combo, to make way for new symbols that come down from above and fill the space. The cascading wild feature therefore gives you the chance to get more wins on a single spin.
  • Random Wilds – as the name suggests, these symbols can appear randomly during gameplay and replace standard symbols with wilds. Occasionally they appear in the base game, but they are more common in bonus rounds or free spins.
  • Moving Wilds – also known as shifting wilds or walking wilds, moving wilds move across the reels once dropped. They usually move one position on each re-spin until they are completely off the reels. They increase your chances of consecutive wins on every re-spin.
  • Added Wilds – added wilds are extra symbols that function as a substitute wild symbol. Added wilds are more common in bonus rounds or free spins than in the base game. They provide more opportunities to complete winning combinations.
  • Contagious Wilds – here a wild symbol turns the symbols next to it into wilds. Contagious Wilds can appear vertically, horizontally and in some cases diagonally. They can turn a single symbol into a wild or they can turn multiple symbols into wilds.

Slot Variance: Check the volatility of your games

Slot variance, also known as slot volatility, is a term that describes how often you can expect to win when playing a slot. It is a relatively new concept that has become an important factor in the choice of slots for experienced players. While the RTP gives you an indication of the expected long-term profitability of a game, the variance indicates how often you will win and how big the payouts will be. The variance describes the risk level of a game and can have a major impact on the overall gaming experience. It can help you determine how to manage your bankroll as you play. Here you can learn more about the characteristics of low, medium and high variance slots.

  • Low variance slots are low risk slots. While playing you will often find winning combinations, but the payouts will be relatively small. The benefit of the best low variance slots is that frequent wins help stretch your bankroll, giving you a lot of playtime for your money. They allow you to play for long periods of time without your bankroll fluctuating wildly.
  • Medium variance slots are a good compromise between low and high variance slots. They offer a balance, with fairly frequent small wins, but also the opportunity to get bigger wins while playing. Often you will see such slots have a wide range of payouts based on the paytable and bonus features.
  • High variance slots carry a higher level of risk, but they offer the potential for greater rewards. When you play on such slot machines, you will not often get winning combinations. However, when you win, the payouts will be big. You can see your bankroll drop significantly before you make a decent profit, so these are best for experienced players with a big budget and a lot of time.

How to win at slots? [Guide]

We've all been there – wondering how to win at slots and roaming the deep darkness of the internet. There are some popular myths, such as the hot and cold slots, but they simply don't hold up because of the random number generators. The RNG used by reputable casinos ensures that all spins are truly random, and not fixed in any way. That's why many well-known strategies for winning at slots just don't work. Slots are games of chance, where it comes down to luck whether you win or not. That said, there are some slots tips you can use to improve your overall gambling experience.

  • Play with a casino bonus .
  • Play reliable slots with the highest payouts.
  • Determine the volatility of slots to estimate the risk.
  • Choose a software provider you feel comfortable with.
  • Try out slots for free.
  • Play at recognized, trusted online casinos.

Always take advantage of free slots

While it is true that you cannot win real money playing free slots, you should not underestimate the value of demo slots. Playing free slots gives you a chance to check out the features and get a feel for whether you like the game before spending any money. Almost all slots are available in free mode, so you can try out the different types of slots and find the ones that suit you perfectly. You can try out the different options and settings, adjust the coin value and change the number of bet lines to fully prepare for real money play.

Play with no deposit free spins

Playing is fun, but in the online casino it is even more fun. Many casinos give free spins without a deposit . You can use it to test slots such as Starburst , while you also have a chance to win real money prizes.

Play with bonus

In addition to the free spins, you will also receive a welcome bonus at every decent casino that amounts to at least 100% of your deposit. That free money with no deposit bonus is another way to play with a slots bonus .

How do I find the best casinos with online slots?

The most important thing to look for is the casino license . All casino websites must be licensed by an accredited body. In addition, it is a matter of personal taste. Find a casino with a large selection of slots in the library, and a theme that you like. Also look at the bonuses and casino promotions that the casino offers. Many casino sites have regular promotions that take you way beyond the welcome offer, and VIP schemes for loyal players.

Are slots really random?

In a word, yes. If you are playing at a licensed and regulated casino, the slots are controlled by the RNG and the casino cannot interfere with the game. This means there is no 'good' time of day to play, and the chances of hitting the jackpot don't increase or decrease the longer you play. It also means that the games are completely fair.

How can I win a progressive jackpot?

The chances of winning are pretty slim, but with such a big potential payout, it's hard to resist. Most progressive slots require you to place the maximum bet each round for a chance to win.

Which slot themes are available?

Almost anything you can imagine. There are many slots based on famous movie and TV franchises, for example. With many thousands of slots on the market, you are sure to find a slot that suits your taste.

Have the slot demo modes been sabotaged?

Not at all! Some people are suspicious that when a slot is in demo mode, the game has been manipulated to appear more favorable and thus encourage you to play it with your own money. In reality, the demo mode free slots are controlled by the RNG in exactly the same way as the real cash games. The experience is identical - except, of course, that you can't win money in demo mode.

What is the payout percentage of a slot machine?

Usually slots are programmed to pay out between 82% – 99% of all money wagered. This theoretical payout percentage is known as the RTP or Return to Player percentage. The RTP of a slot machine is usually stated in the game rules. Online casino slots with the best odds are those with a high RTP.

Are the slots manipulated?

Slots are not tampered with when you play at a reputable casino. Licensed casinos use a random number generator (RNG) to power their games and ensure that all results are fair and not false in any way. In addition, reputable casinos invite independent testing of their RNG and game payouts to verify their integrity.

How do slots pay out?

Slot machines are programmed to pay out a certain percentage of all money wagered on them. This payout percentage usually ranges from about 82% to 99%. For example, if a slot has a payout percentage (RTP) of 95%, for every AUD100 wagered on the game, AUD95 will be paid out to players as long-term winnings. Check out our best paying slots guide to find slots with the highest payouts.

What is the minimum deposit required to play at the top slots sites?

All slots casinos have different deposit requirements, which can also vary depending on the payment method chosen. In general, however, most online casinos require a minimum deposit of AUD20, although they may also accept a minimum deposit of AUD10 . For more information, we recommend reading the corresponding review and terms and conditions of each slot casino.
