Slots are the most popular games that are played globally in both brick-and-mortar casinos worldwide as well as those online.

Well, if this is the case, you should definitely try to find a site that offers the online gambling site on mobile and desktop. Many casinos offer real money slots mobile and some sites even offer no internet slots.

Classic Slots vs. Casino Slots Online Games 

online slots

Although most casinos now have reels which are button operated (unless you’ve found yourself playing slots in a land-based casino frequented by dinosaurs), the original aforementioned slot machines needed a much more athletic arm to guide the playing process than new casino slots games as they were operated by players pulling down on a side lever. It was this particular part of the machine which earned this much-loved contraption the tongue-in-cheek moniker of the “one-armed bandit” (it was called this due to the fact that it had a reputation for “robbing” players of all their money deftly). Nowadays, this term has been extended to the player himself, with players who strategically operate a number of machines at once being labelled “multi-armed bandits” (or maybe we should just call them greedy).

The principle behind the slot machine, like the game itself, is a simple one. Slot machines are embedded with currency detectors which validate the money inserted to play (much like you would find in a drinks machine) and the amount one gets in winnings depends on the patterns of symbols which come up when the reels stop turning. Traditionally, the more uniform horizontal or vertical patterns you got, the bigger the payout, however, modern technology and particularly online casinos have made winning easier by introducing a bevvy of variants on the traditional patterns. It is truly not for nothing that slot machines are the most loved games and constitute roughly 70 per cent of the average online casino USA's income. Big money slots have become big business for all those want a piece of the million-dollar slots pie!

  Facts about Slots:


  •  Slots are the most played casino games at land-based casinos as well as on desktop and Mobile Casino;
  •  New Slots games at many an online casino are introduced every week due to the high demand;
  •  There are three types of slot casino machines: multiplier, multi-line & progressive slot games;
  •  Very often Slots players benefit from special types of bonuses such as Free Spins Bonuses.

How to Play Slots Online: Tradition and Technology at war!

Since online casinos are not brick and mortar casinos, players will obviously be partaking of digital or video slots machines which don’t have moving parts as such, but graphical representations of symbols instead. It is thanks to this flexibility in design that many video slot machines come with further interactive elements such as advanced bonus games and graphics. Furthermore, because there are no mechanical restrictions, the number of reels offered are often different. In fact, you’ll notice that many online Slots out there have five reels rather than the standard three which leads to a wealth of possibilities.

The reality is that even if you prefer to use no-download software to play slots online, you really should know that the game variety online is pretty huge and you’ll be able to find everything from classic one-arm bandits (without the energetic pulling), to very advanced video-slot machines that more resemble video games than the old 3-reeled games.

Slots Online Games are Relatively Simple to Play

Slots online machines are relatively simple to learn how to play, but there are plenty of variations and it does pay to take the time to understand them instead of diving straight in. Ultimately, which Slots online game you choose to play is obviously a matter of taste as while some players look for popular slot games and want their games to be very straightforward with one pay-line and the classic cherries, bars and sevens generating (modest) winnings, others look for slot machines online with elaborate rules, large progressive jackpots, 20 pay lines, bonus rounds, and maybe even a story-based game that takes them through different stages.

  Things to remember when playing online Slots: 


  •  Although the underlying rules of Slots are predominantly the same, you must remember that each casino slots game has different rules; 
  •  The lion’s share of Slots games have a very high house edge;
  •  Progressive Jackpot Slots are the most lucrative types of Slots online games but have the highest house edge.

Slots App vs. Free Slots App

As the use of mobile devices increases, there has become a greater demand for both the real money slots app and the free casino slots app. While a real slots app will mean that people will finally be able to play for real money while being on the go, a number of people are looking to download the best slots for free app where they can play for free and practice all their skills before moving onto the real thing. While in the past the average app with slots free constituted the basic three-reel format that we saw in many classic slots app, times have indeed changed and you would even be able to get a free scatter slots app if you were to look hard enough.

 Using a Strategy for Playing Online Slots With Real Money 

Once you’ve learnt the basic rules of slots online, it’s time to think about something a bit more complex - online Slots Machine Strategy. Ultimately, learning how to implement a strategy while playing online slots for money can help you bag even more cash than you typically would without using strategy. There are several ways of improving your chances at winning at internet slots and these are covered in depth in our slots online strategy guide.

Slots Money Management

Slots money management is an important feature of effective gambling and your luck will be in for a much smoother and easier ride if it comes with a plan and a purpose that you unflinchingly stick to.  Below we have outlined the top slots money management tips:


Understand how much money you need in your bankroll for an enjoyable slots experience and when you discover precisely this, come hell, high water or the second coming, YOU DON’T BUDGE.


Now that you’ve decided on your amount and the machine you want to play at, the next part of being a slots money management king or queen involves you figuring out how much you are willing to wager in an hour.


If you do finally manage to make a tidy sum at the slots, then do yourself a favor and don’t put all of it straight back into the machine again. Try to keep a percentage of what you have won separate from what you plan to play with and don’t touch it


The faster and longer you play, the more money you will lose in the long run. You can slow down the rate at which you lose if you play slower. In addition to this, if you decide to make a habit of playing slower at all casinos, chances are you will be able to make better decisions about your next move because it would have been more thoroughly thought out.

Different Varieties of Online Slots For Real Money 

Online slot machines are relatively simple to learn how to play and pretty much do what it says on the tin. That said, there are plenty of variations and it does actually pay to take the time to understand them instead of diving straight in. The three main types of games that you will have to choose between are multiplier, multi-line and progressive slot games. Here is a brief overview of each:

  Classic Slots Games or Fruit Machines

Classic Slots Games found online are digital replicas of fruit slots and other old-school slots games that are generally found at brick-and-mortar casinos. So if you like the timeless look and feel of fruit slots and you can do without all the flashy symbols and music, Classic Slots are probably the best fit for you. You can just sit back relax and enjoy the wild rush of the spinning Slots reels as they come to a dramatic halt.

  Video Slots

In this day and age, Video Slots are perhaps the most popular out of the lot that can be found on the net. They mesh classic gameplay together with captivating modern design. Provided that you wish to find interesting Video Slots to play, you’ll be able to find an interesting range of themes ranging from Egyptian themes, Superhero themed Video Slots, Fantasy themed Slots games and many, many more. Unlike traditional mechanical machines, video slot machines are designed for players to play multiple lines in any patterns designed and integrated by the manufacturer. This could mean that winning lines can be from side-to-side, corner-to-corner, or even from the middle of the game face upwards.

  3D Slots

Do you like a good story? If so, you’ll be happy to know that not only do 3D Slots are part video game, part Slots. As you spin the Slots game’s reels, you’ll be able to progress through different levels, work on mini-challenges and more.

  Multiplier Slots

The rules which govern the multiplier game are pretty simple, in fact, the more coins you put in (up to a maximum which is often five coins but can be more) the more money you will be eligible to win. Indeed, when it comes to multiplier games, each extra coin multiplies the pay-out, so that if three bars pay 10 for one coin, they will pay 50 for five coins. Furthermore, some slot symbols will only multiply your wins, while others will only count towards your line bets and total bets. Each game offers its own instructions with regards to the use of symbols; therefore, it is important to understand the worth of each symbol you are dealing with based on the game you are playing.

  Multi-Line Slots Games

In a traditional slot machine, you only get paid if the three symbols on the center line match (or if you get some kind of special symbol that pays off without having to match all three). Although you might be able to see three lines in most machines, the matching of three symbols at the top and bottom lines do not offer any return. In a multi-line machine, you can activate those lines by adding extra coins. Some machines allow you to play 20 or more by having, for example, five symbols across with pay-outs for horizontal, diagonal and angled lines. Thus, one doesn’t have to wait for the traditional three in a row to make a decent killing.

  Progressive Slots Games

Despite not being part of the original set-up, progressive machines form part of the most popular types of slots, both live as well as online. A progressive jackpot is a jackpot which is usually linked to a gaming machine which takes a portion of the amount invested by each player and puts it in a progressive pool with a large, hard-to-hit jackpot. Everyone who plays on the machines which participate in the progressive pool contributes to this jackpot, and when it is hit, it can even reach dazzling heights of $1 million or more. Interestingly, while the linking of machines usually happens at the same location, casinos in New Jersey, Nevada and South Dakota are now offering multi-state progressive jackpots which obviously have huge payouts. You must play the maximum amount of coins per spin that the machine allows in order to be eligible for the progressive jackpot. The thrill of playing slots online is almost synonymous as playing the multi-reeled game at brick and mortar casinos in the world's gambling meccas. However, one must say that there's way more to choose from online. If you've never played slots before and would like to give playing the casino game a shot without having to pay real money in the process, we suggest you try it for free right here at CasinoTop10!

  Virtual Reality Slots Online

Although VR Slots online are not the most popular Slots variations you’ll be able to find online, they are slowly gaining popularity as many players opt to invest in proper virtual reality headgear to use whilst playing their favorite VR games. So far amongst the most popular titles available at Slots casinos are Beanstalk, Starburst, Dracula and more. Provided that you’d like to learn more about VR at casinos, we recommend heading to our Virtual Reality Casinos page which provides a detailed guide to what you can expect at casinos that support VR as well as the most popular games that are available to play.

What are Scatter Slots?

Scatter slots are called so because of scatter symbols. Scatter symbols are symbols which can set an entirely new sequence of events into motion and affect a slot machine's payout or bonus. Although many players are of the belief that scatter symbols solely exist to sweeten the pot by ALWAYS multiplying your winnings, unfortunately for us and you, this is not always the case. The reality is that while scatter symbols can often be used to multiply the amount you can win, by definition that is not specifically what the “scatter” term means.

In a great number of scatter symbol games, if two scatters appear anywhere on the screen, you will double your prize amount on that particular spin. Moreover, three scatter symbols will quadruple your win, and four scatter symbols will give you nine times the original payout. However, not all scatter symbols are created equal and in fact, in some particular slots online games found bouncing around the net, scatter symbols have been known to trigger a bonus game or even a fixed prize for combining three specific scatter symbols. What is imperative for you the player to remember is that scatter symbols don’t actually say anything explicit about the kind of prize that you will be receiving, only that you will get a prize no matter where on the screen the scatter symbols appear.

Slots Bonus Game - The gift which keeps giving!

A slot online bonus game is a game that you will receive access to when you hit a required combination. The combination required can be anything from three scatter symbols, to three specific bonus-game symbols, or perhaps even a certain symbol on a specific reel. When it comes to slots online bonus, the important thing to remember is that online slot games with bonus rounds are not simply played on "normal" machines which mean that you need to ensure that your machine actually does offer slots bonus games before dropping your cash. When it comes to slots bonus games, the machines either have regular reels which have been altered especially so that a plethora of other symbols appear, or the normal symbols remain intact but have a different value from what one would usually find. In addition to these changes, some machines even have additional reels added to them. That said, these mechanical changes are obviously not possible on new advanced video slot machines due to the fact that everything is conducted digitally, thus, if you want to play slots bonus games online, you need to choose the specific game from the get-go.

Free Spins

Who doesn’t like free stuff? Free spins are exactly of that category, if you hit a particular, required combination, you will receive a number of free spins that will keep you occupied for hours at a time. Feeling greedy and wanting even more free spins? Ironically, the payout for certain combinations is increased even more during free-spin mode! Thus, not only are you winning extra spins whilst playing for absolutely free, but if you manage to hit new, free spins during the free game you’re playing, these are added to your running spins. One game that offers free spins is the Book of Ra game which is especially popular with Europeans. 

Wild Symbols - It's a jungle out there!

If you google what wild symbols are, you’ll find anything from urban legends to full-page descriptions about the origins of this much-loved wild card in the slots pack. For those of you who are still green and fresh to the slots world, a wild symbol is the metaphorical joker in the pack and acts as a substitute for other symbols in order to aid you in creating winning combinations. That said though, despite the fact that wild symbols are indeed fancy, they can’t usually be substituted for bonus symbols or scatter symbols, but then again, this does differ from machine to machine which means that you should always read the terms and conditions of every game you sign up for beforehand (this is something that we really can’t stress enough whether you’re playing slots or anything else for that matter). Choose wisely and you might even end up with a series of wild symbols which will give you a big, fat paycheck.

The Colorful History of Casino Slots

The Early History of Real Money Slot Machines

casino slots

Whether you’re a gambling connoisseur or a green newbie just starting to dip your toes in the casino pool, there are few people on earth who haven’t heard of or played the iconic game of slots which has been reincarnated in dozens of different shapes and forms. Indeed, so well-known is the once humble slot machine that its actual name exists in several different forms which are widely used by people coming from different countries and cultures. Indeed, while the British refer to slots as ‘the fruit machine’ which makes a contextual reference to some of the first slot machines where the player would need three or more matching fruit symbols to win, the Scottish like to call it ‘a puggy’, and Australians and New Zealanders refer to this pop culture icon as ‘pokies’.

Undoubtedly, while there is a vast divergence in the names used to describe slot machines, it is widely corroborated by aficionados everywhere that the granddaddy of the modern machine was born in Brooklyn, New York in 1891. Based on poker, this particular gambling machine created by Sittman and Pitt consisted of five drums which had a total of 50 card faces and after players inserted the mandatory nickel and pulled down on a lever, they would wait till the drums stopped spinning to hopefully give them a good poker hand. Ironically, the first slot machines didn’t offer any payouts whatsoever and in fact, winners would be rewarded with a number of drinks and cigars based on how good their win was. Sometimes, in order to make the odds better for the house, two cards were taken out of the deck: the ten of spades and the jack of hearts. These particular cards double the odds against winning a royal flush. Furthermore, the drums could also be rearranged to further reduce a player's chance of winning.

This version was soon followed up by a device made by Charles Fey of San Francisco, California which was composed of a much simpler automatic mechanism which had three spinning wheels which had a total of five symbols: horseshoes, diamonds, spades, hearts, and a Liberty Bell. In fact, it was the bell itself which gave the machine its name. By replacing the ten cards with five symbols and using three reels instead of five drums, the complexity of reading a win was considerably reduced which allowing for Mr Fey to come up with an effective automatic payout mechanism.

The Advances of Real Slot Machine Games

By the turn of the 20th century, these machines were a common sight in New York bars and soon spread further afield. However, it was ultimately improvements in technology which led to the first electronic slot machine in 1963 followed by the first video slot machine in 1996. The Bally Company was the first to develop a fully electromechanical slot machine, which is the basis for the mass-produced slot machines that appear in row after row of casino floors today. The slot games quickly branched out to include various themes and methods of winning, including multi-line payouts and multiplier machines that pay more per spin the more you put in.

Modern Slot Machines for Real Money 

Today, Slots machines are fully computerized. Many no longer take metal money, requiring patrons to put in paper money for multiple spins or to use a pre-paid card. Online casinos also have no shortage of slot action, with countless variations on slots according to theme, style and payout structure.

Biggest Slots Wins of All Time

There is a feeling of excitement you hear about or even see someone score big in a casino, whether it happens at a high stakes blackjack table, with one spin of a roulette wheel or on a progressive jackpot offered from a stingy slot machine. Many people have seen their lives change, and many wealthy individuals have become even wealthier based on a single play. Here are some of the biggest casino wins of all time.

Kerry Packer Scores Millions at the MGM Grand

The year was 1997, the scene: MGM Grand, Las Vegas, Nevada. The late Australian billionaire and high roller Kerry Packer strutted into the Las Vegas MGM Grand and strutted out over $20,000,000 richer.

Though local lore has pushed the amount to potentially 40 million, it can be confirmed that the final tab was between the 20 and 40 million dollar mark over the course of a few days. Though this certainly qualifies as one of the biggest casino wins of all time, it doesn't really offer more than the raise of the brow to the regular guy or gal. After all, Packer is a billionaire. It might be more impressive to know that he lost 28 million in a single, quick stretch only two years later.

Good Things Come to Those Who Wait

At the age of 76, Elmer Sherwin scored on a megabucks jackpot progressive slot scoring a cool 4.6 million. He soon found that his desire to see the world had a nearly unending source of financial backing. Not to be labelled a one-hit-wonder, Sherwin hit the same jackpot again 16 years later in the year 2005 at the age of 91 for a whopping 21 million. Visiting the fabulous Fremont Hotel and Casino in Las Vegas, tourist Amy Nishimura, boasting the young age of 71, also saw a huge return on an investment after plugging an approximate $100 into a megabucks jackpot slot. She scored a hit of 8.9 million dollars. After scoring her hit, she claimed to have dreamed of the moment during the nights leading up to the event.

A Single Hit for the Ages

The Excalibur Hotel and Casino boasts a wonderful reputation for great gaming, and during March Madness (NCAA basketball tournament) of 2003, a young man from Los Angeles chose to kill some time between games by plugging a few bucks (around 100) into a slot machine. No doubt when he plugged his cash in, he hoped for a small return, but instead, he became the largest hit in Las Vegas casino history: 39.7 million dollars - taken in 1.5 million dollar annual increments, of course.

Historic Life-Changing Internet Slots Wins at Casinos Online

Some of the biggest casino wins in gaming history have happened online - usually in online slots - and this branch of the industry has its own unique jackpot statistics. The first multimillion-dollar jackpot was awarded online in 2002. A progressive online jackpot in the amount of $1.59 million was awarded, and online casinos became more viable in the gaming industry than ever. A new record was set in 2005 when a woman from Florida hit a $1.96 million progressive jackpot through an online slot game. In May 2009, this record was shattered when a Microgaming online player scored a €6,374,434 jackpot, around $8.69 million US. This staggering amount went to a business owner from Greece, who could easily create a new business by offering online gambling tips!
