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 online slots work.
- 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.
- 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 online slots scatters, 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 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.
- 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.
- 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.
- 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.
- 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).
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

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:

- 1492 Uncharted Seas – 98.60%
- Blood Suckers – 98.00%
- Starmania – 97.87%

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.
Mobile Slot Apps
Mobile gaming has never been more popular, and it is easy to understand why.

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 the slots apps for Android can even make the gameplay more engaging than playing on a PC. And those of you who want to play on your Mac can find more useful information at Mac slots online.

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.
| Year | Event |
|---|---|
| 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 | The Fortune Coin Company is acquired by IGT. The company makes various modifications, including extra paylines and streamlined design, marking a significant change in the way slot machines are developed over the coming years. |

| 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 through mobile, Android or iPhone slot apps |

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 best big win slots. 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. |
| Mega Moolah | ￡13,213,838.68 (€17,879,645.12) | 06.10.2015 | Jon Heywood – The British soldier won the Mega jackpot from a 25p bet at Betway Casino. Microgaming were officially awarded the Guinness World Record for the largest jackpot payout in an online slot machine. |

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 slot machine myths that simply refuse to go away, despite proof that they are merely superstitions or no longer relevant. Here are some of the common 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. It’s also true, however, that the statistical data collected in the industry pinpoints which the best payout slots are in practice.
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. Apart from that, we also put games and operators to the test by using a tried and tested ranking system, ensuring player satistfaction and safety from our perspective as well.
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 slot odds 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. High RTP slots are among the most sought-after gambling products. Yet, you should be aware of the volatility or variance, 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.

1. Is Playing Slots Online Legal?
The legality of playing slots online depends on where you reside. For instance, the UK has a fully licensed and regulated online casino industry, meaning it is legal to play online slots at UK gambling sites - through free online slots have recently been banned. Laws vary in different countries and states. For instance, in the USA, it is only legal to play online casino games in certain states, including Pennsylvania and New Jersey. You should check the laws of your own jurisdiction to determine whether playing slots online is legal.
2. How many different symbols are there on a slot machine?
The number of slot machine symbols varies from one game to another, but usually includes 10-12 standard symbols. There are different types of symbols, with many slots including a wild, scatter and other multi-functional symbols as well as the standard versions. You can see a full breakdown of a slot's symbols in the paytable.
3. What's the oldest slot machine symbol?
The first slot machine contained 5 symbols; a liberty bell, heart, diamond, horseshoe and spade. The first slot was named the Liberty Bell, given this was the highest paying symbol on the reels. As such, the liberty bell can be considered to be the oldest slot machine symbol.
4. What is the payout percentage of a slot machine?
Typically, slot machines are programmed to payout out between 82% - 99% of all money wagered on them. This theoretical payout rate is known as the RTP or Return to Player percentage. A slot machine's RTP can usually be found listed within the game rules. The best online casino slots with best odds are those with a high RTP.
5. Are slots rigged?
Slots are not rigged 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 in no way fixed. Furthermore, trusted casinos invite independent testing of their RNG and game payouts to verify their integrity.
6. How do slot machines pay out?
Slot machines are programmed to pay out a certain percentage of all money that is bet on them. This payout rate typically varies from around 82% up to 99%. For instance, when a slot has a payout rate (RTP) of 95%, for every $100 wagered on the game, $95 will be paid back to players as winnings over the long run.
7. 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. It is believed that some land-based casinos may be able to change slot payouts. However, they would need to adhere to the licensing and regulatory standards of the jurisdiction relating to any such modifications.
8. Do Casinos own the slot machines?
Most casinos own slot machines, and it has been reported that around only 15% of Vegas slot machines are rented. Online games, on the other hand, are not owned by any casino operators - even though even when you play slots online for free, you will see the logo of one operator or another.
9. Which is the best time of day to play slots?
The time of day you play slot machines makes no difference to your chances of winning. The theoretical return to player percentage remains the same at all times of the day, so you have an equal opportunity of success playing at any time, any day. The best time to go to the casino to play slots is simply when it suits you best.
10. What are the best online slots to play?
The best online slots to play are those that offer the highest payouts. Games with a higher RTP will pay out more than those with a higher house edge. Identifying the best gamesalso comes down to personal preference, depending on the types of themes and special features you enjoy in a slot machine. You can find the top rated slots online listed on this page.
11. Do Penny slots actually take pennies?
Nowadays, it is very rare to find a slot machine that actually takes pennies. In most cases, you will need to insert bills to be able to play penny slots. When you cash out, you will receive a printed ticket that shows any winnings and how much money you have left.
12. What casino game has the best chance of winning?
The casino game with the best chance of winning is online blackjack. The RTP of blackjack is around 99% when following basic strategy. There are also other strategies such as card counting that can be used by advantage players to reduce the house edge even further.
13. What are flat top slot machines?
Flat top slot machines, also known as straight slot machines have one payline, one jackpot and no bonus rounds or special in-game features. The jackpot in a flat top slot is a fixed amount and does not increase, unlike progressive jackpot slots.
14. What is a two coin slot machine?
A two coin slot machine usually features a boosted jackpot when playing with two coins instead of one. For instance, the jackpot may be 800 coins for playing with one coin, but 1700 for playing with two coins. There are also two coin slot machines which do not feature an added jackpot bonus, with the same payout multipliers applied to one or two coins.
15. How do you find a loose slot machine?
Loose slot machines are a common misconception. Slots are mathematically programmed to pay out a certain percentage over the long term, and each spin's result is determined by a random number generator. Rather than trying to find a loose slot machine, you would be better off looking for the top-rated options, so be sure to check our best online slots review for inspiration.
