Still, there are some slots that are better than others. In the following sections, you will find out all you need to know about how to play. You will learn about the basic rules, the types of symbols, and how to pick games that give you the best chances of winning.

Basic Rules and Game Layout

When you play a slot machine, the aim of the game is to line up winning symbol combinations on paylines. When you land a winning combo, you will receive a payout. Different symbols have different values, and you will generally get a bigger payout the more matching symbols that appear on a payline. The slot paytable displays a detailed breakdown of the payout for each symbol combination. You can change the coin value and bet level to select the bet size you want to make per spin. You then simply click the spin button to play the game. You can select the autoplay option to play a set number of spins in a row. Some games also feature a quick spin option, which reduces the time taken for the reels to spin, providing even faster gameplay. Free online slots give you the chance to try out all the settings and options before you play for real.

Slot Machine Terms

There is no denying that slots are super simple to play. Yet if you are new to the games, there are a range of terms that you may encounter that you may not yet be familiar with. As a beginner, it is useful to get to know these to help your understanding when you play. There are also some advanced slots concepts that more experienced players could benefit from brushing up on. To make life easier for you, we have put together a list of slot machine terms and definitions that you may come across when playing slot games.

Slot Term Definition

5 Reel Slot The most frequently found layout for modern land-based and internet-based slots. 5-reel slots can feature different numbers of rows and paylines.
Action Slot action describes all the slot playing time a gambler has accumulated. It can refer to the number of bets placed, or the total amount of time spent playing.

Buy-a-Pay Buying a pay refers to making a bet that is big enough to compete for the top prize. Some slot machines require your wager to be above a certain amount in order to award the biggest payouts.
Carousel This refers to a group of slot machines which are placed close together in land-based casinos, often positioned in a cluster. For example, dollar slots may be grouped in a carousel.
Cascading Reels When you line up a winning combination, the winning symbols disappear, making space for new symbols to cascade down and fill their place. Thus, players can win from a single spin.
Certified Certified slots have an RTP which is guaranteed by the casino to be 98% – 100%.
Click and Pick A feature frequently used in bonus rounds. You will be presented with a choice of icons, and you click them to reveal either a coin prize, multiplier, free spins, or another type of special feature.

Slot Symbols

The variety of symbols that appear on a slot machine will vary from one game to another. There are some types of symbols that are often found in slots, such as playing card faces and fruits. Yet others will be crafted to reflect the game’s theme. Yet it is not merely the look and design of the symbols that vary, but also their function. There is a range of special symbols which have other functions. Some substitute for others, some trigger special features, some increase your wins. If you want to know what symbols you will find when you play slots online, free slots give you a taster of what to expect. Below, you can find out about all the different types of symbols that you will find in slot machines and learn about how they work.

  1. Standard Symbol – You can see all the standard symbols and their payouts on the slot’s paytable. The more symbols that land on an active payline, the bigger the payout. Normally playing card symbols offer lower payouts. The higher valued symbols are often designed to reflect the theme of the game.
  2. Scatter – Scatter symbols can land in any position on the reels. Scatter pays usually reward you with a payout multiplied by your total bet, unlike standard symbol payouts, which are multiplied by your line bet only. In many slots, scatter symbols are the key to triggering free spins or bonus rounds.
  3. Multiplier – These symbols multiply a standard payout by a certain amount. A multiplier can be a standard symbol and will boost the payout of a winning combo. Some wild symbols also function as multipliers and can boost the payout of any winning combination in which they substitute.
  4. Bonus Symbol – Bonus symbols are the key to unlocking bonus rounds. They often work in a similar way to scatters, in that they do not have to appear on a payline to trigger the feature. Bonus symbols usually reflect the game’s theme very closely.
  5. Free Spins Symbol – Whilst scatter symbols often trigger free spins in a slot, some games have an additional special symbol which can launch the free spins feature. These may need to appear in any position in some games, or on an active payline in others.
  6. Wild – Commonly found in slot machines, wild symbols act as a joker and can substitute for other symbols to complete winning symbol combinations. In most cases, the wild symbol will substitute for all standard symbols, but will not replace bonus, free spins or scatter symbols.
  7. Sticky Wild – This type of symbol is an enhanced version of the classic wild symbol. Sticky wilds hold their position on the reels for a set number of re-spins. This increases your chances of lining up wins on the subsequent re-spin(s).
  8. Stacked Wild – A stacked wild is essentially a series of wild symbols that appear 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 normal wild symbols in succession.
  9. Expanding Wild – Such symbols substitute for others, like a standard wild symbol. However, the symbol will expand when it lands to cover more positions. They commonly expand vertically to fill entire reels, and in some cases, they can expand horizontally across different rows.
  10. Cascading Wild – When a wild symbol lands on a reel, it will disappear, along with any other symbols in the winning combo, making way for new symbols to cascade down from above and fill the space. The cascading wild feature, therefore, gives you the chance to get more wins from a single spin.
  11. Random Wild – As the name suggests, these types of symbols can appear randomly as you play, replacing standard symbols with wilds. Occasionally they can be found in the base game, but they are more frequently featured in bonus rounds or free spins.
  12. Moving Wild – Also known as shifting wilds or walking wilds, moving wilds will move position across the reels once they have landed. They usually move one position with each re-spin until they work their way off the reels entirely. They boost your chances of successive wins with each re-spin.
  13. Added Wild – Added wilds are extra symbols which function as a substituting wild symbol. Added wilds are more commonly found in bonus rounds or free spins, rather than in the base game. They provide more opportunities to complete winning combinations.
  14. Contagious Wild – This is where a wild symbol transforms the symbols next to it into wilds. Contagious wilds can occur vertically, horizontally, and in some cases, diagonally. They can transform a single symbol into a wild or alternatively they can change multiple symbols into wilds.
  15. Reel-Specific Wild – Some slots will only include wild symbols on certain reels. Some examples of reel-specific wilds are those which appear on reels 2, 3 and 4 or on the outer reels only. Thus, players can’t create a winning combination on a payline with wild symbols only.
  16. Extra Wild – Some games have an extra set of wild symbols, which can be added to the reels in the bonus round/free spins only, or in the base game as well. In some cases, you will need to place an additional wager to add extra wilds to the reels.

Themes: From Fruits to Spaceships

The world of slots is constantly evolving, so we may have even missed some of the existing themes. With new and exciting 3D and video slots coming out all the time, there are more and more options for the gambling fans out there, and virtual reality is sure to change the casino world even further. So, it’s always a good idea to keep track of the new slots coming out, especially if you have a preferred software developer.

Slot RTP: The Best Payouts You Can Find

Experienced players will be familiar with the term RTP. It stands for return to player. A game’s RTP is expressed as a percentage, and it shows theoretically how much a slot pays back to players in winnings over the long run. If a slot has an RTP of 96%, this means that for every $100 wagered on the game, theoretically, $96 will be paid out in winnings. The RTP is calculated over many thousands of spins, and as such, your actual profits may deviate higher or lower than the theoretical figure in a gaming session. Yet RTP is a good indication of the expected profitability of a game.

Casino slots with a high RTP, therefore, offer the best payouts. For this reason, playing slots with a high RTP is one of the best tips for how to win at slots. If you want to know what is the payout percentage of slot machines, you can check the game rules. For your convenience, here is a list of the top 10 slots with the highest RTP:

  1. Goblin’s Cave – 99.32%
  2. Ugga Bugga – 99.07%
  3. Mega Joker – 99.00%
  4. Jackpot 6000 – 98.90%
  5. 1492 Uncharted Seas – 98.60%
  1. Blood Suckers – 98.00%
  2. Starmania – 97.87%
  3. Devil’s Delight – 97.60%
  4. Retro Reels Extreme Heat – 97.50%
  5. Couch Potato – 97.43%

Slot Variance: Check the Volatility of Your Games

Slot variance, also referred to as volatility is a term that describes how often you can expect to win when playing a slot machine. It is a relatively new concept that has become an important factor for experienced players when deciding which slots to play. Whilst the RTP gives you an indication of the long-term expected profitability of a game, the variance indicates how frequently you will win and how big the payouts will be. Variance describes the level of risk involved in a game and it can have a great impact on the overall playing experience. It can help you determine how to manage your bankroll as you play. Here, you can find out more about the characteristics of low, medium and high variance slots.

  • Low Variance Slots
    Low variance slots are those that have a low element of risk. You will hit winning combinations frequently as you play, yet the payouts will be relatively small. The advantage of low variance slots is that frequent wins help to stretch out your bankroll, giving you plenty of playing time for your money. They allow you to play for long periods without seeing a huge fluctuation to your bankroll.
  • Medium Variance Slots
    Medium variance slots are a good compromise between slots with low and high variance. They offer a balance, with fairly frequent smaller sized wins, as well as the possibility for bigger wins to be hit as you play. You will often find that such slots include a wide range of payouts based on the paytable as well as bonus features.
  • High Variance Slots
    High variance slots involve a higher level of risk, yet they offer the potential for bigger rewards. When you play such slots, you will land winning combinations infrequently. However, when you do get a win, the payouts will be big. You may see your bankroll reduce significantly before you hit a decent sized win, so they are best for experienced players with a big budget and time to spare.

Types of Slot Machines

To identify the best bonuses for playing slots, you need to look beyond how much extra money you get. Just as important in spotting the best offers is favorable bonus conditions. Pretty much all bonuses come with a wagering requirement, which indicates how many times you need to play the bonus through before you can withdraw your winnings. Low wagering requirements generally offer a better overall deal. Whilst slot games usually contribute 100% towards clearing the wagering requirement, you should also keep in mind that come casinos impose restrictions on certain titles. As such, you should check that the bonus is valid for the games you want to play to ensure that you get a good deal.

Mobile Slot Apps

Mobile gaming has never been more popular, and it is easy to understand why. Playing slots on the go is incredibly convenient and means you can play your favorite games anytime and anywhere you fancy.

Given the popularity of gaming on the go, many game developers have focused on creating games with a multi-platform design, meaning there are few differences between playing on a PC and playing on a mobile device. With that said, there are inevitably some differences that you will notice when you play slots on a mobile device. Given the smaller screen size of tablets and phones, the layout is simplified to avoid cluttering and ensure you get the best possible playing experience. As such, only the essential options will be found on the main game screen.

Other optional settings, such as coin size, quick spin and autoplay are usually accessed in separate menus, which you can easily open with a quick tap of your finger. You will also often find that the spin button is enlarged and sites to the right of the reels. Once you click spin, the button will disappear, giving you the best view of the game in action. The touchscreen operation of mobile slots can even make the gameplay more engaging than playing on a PC.

Land-Based vs Online

Land-based slot machines came into existence long before online games became available. Online slots are based on their counterparts in real casinos. They have a lot of things in common, yet there are also differences to be seen. When you consider the actual gaming experience, in real casinos, slots use enhanced technology, with cabinets that feature flashing lights and epic sound effects. Yet the basic gameplay works in the same way. Online slots have the advantage of convenience. You can play from home, or even out and about with mobile slots, without the need to travel to a real casino. You will never have to wait to play an online slot either, with an unlimited number of players able to play the same game at any time.

Slot History: From Charles Fey to Virtual Reality

There are some casino games which have a long history, spanning centuries. The origins of roulette for instance can be traced back as far as the 17th century. Whereas the first casino slots did not appear until towards the end of the 19th century. Slots may be relatively new in casino history, yet they have evolved and developed significantly to become immensely popular, by far the most popular of all casino games. We have created a timeline, detailing the significant events in the history of slots.. See how the games have evolved over the years from the first slot machine into the slot machines of today and the future.

Slot History Timeline
1891 New York-based manufacturing firm, Sittman and Pitt develop a Video Poker style gambling machine, which is considered by many as a precursor to the first slot machine. The game had 5 drums and 50 playing cards, with prizes such as beer and cigars paid manually for lining up poker hands across the central payline.
1887- 1894 Charles Augustus Fey invents the first true slot machine, with 3 reels and a single payline. It is named the Liberty Bell, after the highest paying symbol on the machine. The actual date of the first slot is widely regarded to be 1894, with some sources indicating Fey started developing the concept as early as 1887.
1907 Chicago based manufacturer, Herbert Mills enters the slot machine market with the Operator Bell. Owing to laws prohibiting slot machine gambling, payouts would be made with different flavored fruit gumballs. The Operator Bell was the first slot to introduce fruit symbols as well as the BAR symbol, which was an adaptation of the Bell-Fruit company logo.
1964 The first fully electromechanical slot is released by Bally. Money Honey is the first slot machine with reels that are entirely electronically operated. It features a bottomless hopper, meaning it can pay out up to 500 coins automatically. Electromechanically slots increasingly dominate the market in the following years.
1976 The first true video slot is premiered at the Las Vegas Hilton Casino. Developed by the Fortune Coin Company of California, the machine features virtual reels and a modified 19-inch TV for the game’s display. After modifications are made to meet standards required by the Nevada State Gambling Commission, the slot machine is rolled out across the Las Vegas Strip.
1978
1986 Megabucks, the first progressive jackpot slot linked between different Las Vegas casinos is launched by IGT.
1996 The first online casinos are launched with a small selection of online slots, powered by Microgaming. As the internet booms, slots selections multiply. Many new specialized slots developers enter the market. With enhanced technology comes ever more imaginative and creative configurations, paylines, and features. Popular land-based games are adapted for online casinos and original new titles are developed.
2003 The biggest ever recorded slot win in history to date. The winner scoops the $39.7million jackpot playing the IGT Megabucks slot at The Excalibur casino Las Vegas.
2007 The first online slots compatible with mobile devices begin to appear. Over the following years, the mobile gaming trend booms, and nowadays players have instant access to paid or free casino slots.
2015 The largest recorded jackpot payout in an online slot machine. The UK player wins £13.2m ($20.1/€17.8) playing Microgaming’s Mega Moolah jackpot slot. Remains the current Guinness World Record holder.
2015 SlotsMillion releases the world’s first real money virtual reality online casino application. Over 40 VR slots are featured, including Starburst, Twin Spin, and Foxin’ Wins.
2018 Mega Moolah strikes again and sets a new record. In September, the machine pays €18.9 ($21.7m) to a player on a mobile device. To date, Microgaming’s progressive jackpot network has paid out over €948 million, the largest in the online industry.
2018 onwards The VR slots trend takes off. NetEnt announce the launch Gonzo’s Quest VR; the first web VR slot for desktop and mobile.

The Biggest Slot Wins in History: Top Jackpots

There is no denying that jackpots often steal the headlines when it comes to the biggest ever wins. In fairness, regular, non-progressive slots give you more chances to win, albeit smaller amounts. The appeal of progressive slots, however, is that they offer a high reward for a high risk. The jackpot networks of Vegas have produced some of the biggest slots wins of all time. A special mention must be given here to IGT’s Megabucks, which pays out jackpots that exceed $10million. Some of the most famous big slots wins of all time have a quirky story behind them that makes the win even more interesting. Here are the most famous big slot wins:

Slot Game Jackpot Date The Lucky Winner
Megabucks $34,959,458 26.01.2000 Cynthia Jay-Brennan – The second biggest jackpot ever was scooped by the cocktail waitress playing the Megabucks slot at the Desert Inn Casino. Just a few months later, Brennan was in a car accident that left her in a coma and killed her sister. Touted by some as proof of the so-called curse of the Megabucks.
Megabucks $39,719,826 21.03.2003 Anonymous – A 25-year old software engineer from Los Angeles struck the jackpot on the Megabucks slot at the Excalibur Casino in Las Vegas. He chose to remain anonymous. It is the largest slot jackpot ever won to date.
Megabucks $21,147,947 15.09.2005 Elmer Sherwin – The 92-year old won the $21.1m jackpot on the Megabucks at Cannery Casino North Las Vegas. This was Sherwin’s second win, after scooping $4.6m on the same slot in 1989.

The player cracked the jackpot playing on an Android mobile device at Grand Mondial Casino. The win exceeds the current online world record set in 2015, but is not yet officially recorded.

Myths and Superstitions

When you look for tips on how to win at slots, you will encounter various strategies that claim to give you an advantage. The truth of the matter, however, is that they do not work, especially when it comes to playing online. Some could have potentially been used in the days before modern random number generator technology generated results. Regardless, there are some myths that simply refuse to go away, despite proof that they are merely superstitions or no longer relevant. Here are some of the common slot myths, which have been debunked.

Hot and Cold Slots

The idea of hot and cold slots indicates whether a machine is on a hot streak of payouts. Or vice-versa, where cold slots are not giving out many payouts. In reality, this is an old superstition, which although may have had some merit back in the early days of slot machines, nowadays is not relevant. Thanks to RNG software in slots, each spin is an independent event, and completely random. As such, there is no such thing as hot and cold slots nowadays.

Loose Slots

One strategy is to search for loose slots. Such slots supposedly give bigger and more frequent payouts. The truth, however, is that there are no loose slots. The payouts of any slot machine, both land-based and online are determined by a theoretical payout percentage (RTP) and a random number generator. This strategy originates in the belief that casinos used to place so-called loose slots in prime positions to attract players.

You Can Predict When a Payout is Due

A commonly held belief is that a slot which has not paid out in a while is due to payout soon. This strategy is again debunked by RNG software. Whilst casino sites may advertise a highly building jackpot slot, it does not mean it is due to be hit. With each spin being an independent event, the size of the jackpot does not influence your chances of cracking the prize.

Online Games Are Rigged

There are some players who refuse to play on the internet, under the false impression that online slots are fixed. The truth is that online casinos must adhere to strict licensing rules. They are regulated by respected authorities, such as the UK Gambling Commission and the Malta Gaming Authority. Licensed casinos invite independent testing of their RNG software and payout percentages, to verify that their slots are fair.

Slot Scams: Cheating the System Since the 1900s

Since slots were created, people have always been trying to beat them. Throughout history, there have been a variety of slots scams, some more successful than others. Where a scam was detected, developers made the necessary modifications to tackle the scam head on. Technological advancements over the years have further protected slots from manipulation. Whilst there is no way to cheat slot machines nowadays, let’s take a look at some of the successful scams throughout the years.

  • Manipulated Coin – A popular method, used to adjust the machine’s registered balance. The system involved attaching a piece of nylon wire to the coin, to be able to feed it into the machine numerous times, enabling you to play for free and win real money.
  • Cash Dispenser Manipulation – A strategy to win without actually playing. With insider knowledge, some players were able to prompt the slot machine to trigger a payout. This was achieved by sending a signal to the cash memory, in some cases with magnets, to manipulate the cash dispenser.
  • Forcing reels to stop – When a slot’s reels were stopped electronically, a scam employed by a resourceful player involved using an electromagnetic pulse from an electric lighter to trigger the reels to stop in a certain, winning position.
  • Software Manipulation – an option whereby any weaknesses in the electronic printed circuit board would be manipulated. This would force a software reload in safe mode, which could be used to the player’s advantage.

Stats to Keep Track Of

Serious players will keep track of a wide range of statistics. Perhaps most significant in choosing slots with the highest payout is the RTP. Yet the volatility or variance is also monitored, as it can have a big impact on the overall gaming experience, as well as how often you can expect to win. On a personal level, players can monitor their own playthrough history, which details how much money has been wagered, won and lost, as well as providing information on the amount of time spent playing – of course, if you don’t want to invest too much money into it, free online slots provide the perfect way to run a simulation. Below you can see an overview of some of the slots stats that can be monitored.

Are slots rigged?

Furthermore, trusted casinos invite independent testing of their RNG and game payouts to verify their integrity.

Do casinos change slot payouts?

Online casinos cannot change slot payouts. In fact, the RTP is programmed by the game developer and it cannot be adjusted by the operator.
