How Online Slots Work

If you understand how online slots work, it will be easier for you to make the best choices about which online slot games are worth your time and money… and which ones you might want to avoid.

Even the simplest online slots are a mix of sophisticated technology to ensure that all results are completely random and unpredictable. This way, you can trust that you have as much chance of winning as any other player with any single spin.

The Random Number Generator

A Random Number Generator (RNG) is the software that powers the game. This is what ensures that online slots offer a completely random and fair result. The RNG helps the game to come up with a sequence of unique symbols whenever the reels are spun. This adds the game’s risk in the fairest way possible - so that it’s impossible for anyone to predict what outcome the next spin will produce.

If we have a standard 5-reel and 3-row game, the number of possible outcomes is actually in the billions. RNG software is what ensures that each outcome has an identical chance of appearing on each spin, no matter what the previous spin was.

Rows, Reels and Paylines

You also need to understand the layout of online slots. The reels are the vertical columns of symbols that spin. The rows are the horizontal lines of symbols across the game screen.

There can be a variety of different reel numbers in a game, but the standard number is 5 (or 3 for retro slot machines). There can also be a varied number of rows. The standard number is 3, but there can be 4, 5, or even higher for Megaways slots.

Then we have the payline (also known as the betting line). This is a pattern that is drawn across the game grid. It might be straight across, or even in all different zig-zag shapes across the grid. If you land a matching set of symbols across one (or more) of the paylines, you land a win. How much you win depends on which symbols land and how many are involved in the win. Some online slots have fixed paylines, which will be shown in the game’s paytable. Others have flexible paylines, which means you can choose how many active paylines you want per spin. This is more common for classic slot machines.

Cascading Reels

In more recent years, game providers have started changing things up. They have found ways to create even more winning potential.

Cascading reels (also known as avalanche reels, tumbling reels, or rolling reels) are a great example. With cascading reels, the winning symbols are removed from the grid and replaced with new ones. This can generate another win. The process keeps going until there are no more winning combinations. What could have been a single win can turn up into numerous wins with just one spin.

Paytable and Coin Value

The paytable will show you the value of each symbol, and explain each feature. You can learn how to hit wins - and how much your wins would be worth. You will find the paytable in the slot game’s information tab.

The coin value is the amount you bet per spin, and is represented as a literal coin. You can change the amount you bet on each spin - and most online slots have a huge betting range - sometimes between 0.10 up to 100 or even more per spin.

Winning Ways

Different slot games come with different ways to win - let’s look at some of the most common:

243 Ways to Win

This payline format is available in several popular online slots. It means that there aren’t actually any fixed payline, and the wins are simply generated from 3 or more matching symbols landing on adjacent reels.

Win Both Ways

This means that instead of wins only being made from left to right, wins are formed in both directions. A win-both-way game would award matching symbols on a payline on reels 1, 2, 3 (and 4,+5), as well as on reels 5, 4, and 3 (2 and 1). Most slots are left to right only, unless stated otherwise.


If you like a bit of variety, you may be interested in playing a Megaways slot game. This game mechanism was created by Big Time Gaming. The ways to win change every time you spin. The games offer thousands of paylines and ways to win change when you press spin. The number of rows and reels will change, as well as the number of paylines. This means that you never know what you’re going to get!

There are lots of cool slot games here at LeoVegas that use the Megaways game mechanism - and some classic games that have been given a Megaways facelift. Some of the best available include Vegas Megaways, Starz Megaways, Primal Megaways, LeoVegas Megaways, Twin Spin Megaways, Buffalo Kings Megaways, and many more.

How To Play Slots Online: the Basic Rules

Before you start playing slots online, here are some rules to stick to, so you can enjoy the best experience possible.

Find The Type of Game You Want to Play

There are all kinds of slot games available now - we’re no longer tied to the classic fruit machine game. However, what one player likes might not appeal to another. So, you can explore to discover what type of game you like.

Apart from the theme, it would be helpful to find out what volatility or variance you prefer. Do you like high volatility games - with bigger wins coming less frequently? Or do you like low volatility games - small wins more often? Decide what you want and choose a game based on that.

Try For Free

If you are based outside the UK, you can try out games for free in demo mode before playing with real money. This is the perfect way to try the games out first, check the features, and get the feel without risking anything.

Stick to a Budget

When playing with real money, you should set a budget and stick to it. Never spend what you can’t afford to lose. It can be expensive if you start getting out of control. The budget will help you to work out how much you want to spend per spin and find a game accordingly.

Take a Look at the Paytable

Read the game’s information to find out the rules, the different symbols, and their values. You will understand better how the wins are triggered and how different features work. If you are new to online slot games, you might want to start with a one with just a few simple features.

As you play, you might find that you like specific types of features such as multipliers or wilds. So look in the game info and see what features the game has, how you can trigger the features and how much you can expect to win from these features.

How to Play Slots

Before you jump right in and start playing the first slot game you see, you should understand how to play, the different features and symbols you might encounter etc.

As the online casino industry has grown and evolved, the games have changed beyond recognition. Knowing a wild symbol from a scatter will help you to get more out of playing online slot games for real money.

Paying Symbols in online slots

The paying symbols are the core of online slots. These are standard symbols that appear on the reels to create winning combinations. They are based around the theme and go from low-value to high-value symbols:

  • Low Value Symbols: If you look at a paytable, you will find out what the lower-paying symbols are in the game. The paytable usually ranks the symbols in order of value and often the low-value symbols are often playing cards, such as 9, 10, J, Q, K and A.
  • High Value Symbols: These ones are those that pay out much bigger wins when landing 3 or more on a payline. These can be anything and are usually based on the theme of the game.

Wild Symbols

One of the most popular and common slot game symbols is the wild symbol. The wilds can stand in for any regular pay symbol to create wins, and often land big wins when getting 3 or more on a payline. You can get different types of wilds:

  • Standard / Regular Wilds: This symbol simply stands in for any other pay symbol (not bonus or scatter symbols). When part of a winning combination, they will pay out the value of the symbol they are replacing. They sometimes also have their own value for landing 3 or more on a payline.
  • Stacked Wilds (full reel): These wilds land stacked, covering the entire reel. These are popular as they offer a much greater chance of forming a winning combination.
  • Expanding Wilds: Unlike stacked wilds, these land as a single symbol but will grow bigger to cover more spaces on the reel after the spin is complete.
  • Walking Wilds: When the spin has ended, a walking (or wandering) wild will move across the reels in a certain direction as directed in the slot game’s paytable and information section.
  • Sticky Wilds: These are the opposite of walking wilds. These simply stay exactly where they are for a set number of spins. It might be for one respin or it may be for the entire free spins or bonus round.

Scatter Symbols

A scatter symbol (sometimes known as a bonus symbol) is the symbol that triggers the game’s bonus round - such as the free spins round. You would normally need 3 or more to trigger the feature and these can’t usually be subbed by a wild symbol.

Colossal Symbols

A colossal symbol, as the name suggests is a massive symbol that covers more than one space at a time. In some instances, they can cover the entire reels. This could be a 2x2 symbol, 3x3 symbol etc…

Game Features

Now that you know about the different types of symbols, let’s take a look at some of the game features you might find:

Expanding Reels

This is when an extra reel (or reels) is added after triggering a bonus feature. If you add additional reels then there are more symbols and usually more ways to win.

Free Spins

This is one of the most popular bonus features in slot games - and they simply give you free spins - as the name suggests. This is usually triggered by landing 3 or more scatters.

The number of scatters that trigger the feature usually determines how many you get. Free spins often come with higher wins, multipliers and extra features to award more winning potential than in base game spins.


Re-spins are not free spins and shouldn’t be confused with them. These are just a second chance spin which would normally occur in a base game if the first spin ends in no result. It may accompany a sticky wild or other bonus feature.

Bonus Games

Some casino slots offer mini bonus games within the main game. These normally are all about random luck, with no element of skill. Here are some of the most popular bonus games you might find:

  • The ‘Pick Me’ bonus game: This is where the game offers the player different images or symbols to pick from, with each containing a prize. The player wins whatever prize is contained in their chosen item.
  • Bonus Wheels: This is another popular one. A wheel is covered in prizes. The player spins the wheel and whatever prize the arrow lands on, the player wins.


Some games offer multipliers, ranging from 2x upward. These might be triggered by certain symbols (such as wilds etc), they might be accumulated over spins and they come regularly as part of a bonus feature.

Nudge Feature

This is a feature that is helpful if your spin ends one short of a winning combination. The nudge feature might knock the reel one space up or down and give you the win.

Gamble Feature

If you do land a win, then some slot games will give you the chance to gamble the win, which you can either accept or reject. Normally the feature has a 50-50 outcome. If you accept the gamble and win, your win is doubled. If you lose, then you lose the win. It is normally a bet on a random event - such as whether a red or black card suit will be drawn.

Jackpot Slot Games

Some games offer jackpot prizes - the ultimate prizes. There are different types of jackpot slots, such as local, network, fixed, and progressive. Every time you spin a jackpot game, part of your stake goes to form the big prize.

How to Win at Online Slots

Some players simply play for fun, but obviously, it’s even more fun if you start winning. But slot games are simply spin and hope for the best right? Well, yes, but there are some strategies that can help you:

Understand Your Statistics

The difference between a novice player and an experienced player is how much they know about the game stats.

Read up on the information you can find out on that slot game and what it means, and this will help you to determine your chance of winning. If you keep playing a game and it refuses to pay out, you may want to step away and try something else. Just because you have pumped money into the game, it doesn't mean it owes you a big payout.

Consider the RTP

The RTP is the game’s Return to Player and is displayed as a percentage. This tells you how much of your money you should win back from a casino slot game over a long period of time.The RTP is based on a calculation over thousands of spins (or more) on the game and is not a guarantee, the fewer spins you play on a game, the less accurate it will be for you. It should only be used as guidance.

For example, if the game has an RTP of 96.2% then the casino will normally end up with 3.8% of the player’s money spent on that game. This is referred to as the house edge. No online slots have a 100% RTP, or the casino wouldn’t be able to sustain its activity.

So, knowing you’re likely to end up with less, why play? Well, the RTP is only an indicator over time and in the short term, it can be very different. Some players can play 50-times and get 10% of their money back. Someone else might play 50 spins and get a 200% return.

Look at the Game Volatility

The volatility - also called the variance of a game is used to understand the size and frequency of wins. Online slots are usually described as being either low volatile, medium volatile or high volatile.Online slots with low volatility will pay out frequently, but the wins are normally smaller - which is great for new players.

High volatility online slots will normally pay out bigger wins, but these are few and far between. Obviously, a medium volatility game sits somewhere between the two and is the most common type of game.

How do you bet on a slot machine?

Most slot games have a similar betting process. You will usually find a few buttons at the bottom or on one side of the reels. You start by adjusting your stake. You can use the +/- buttons or click directly on your preferred amount to do so. Once you are happy with the stake, you click the Spin button to start. Some slots will also require you to adjust the number of paylines (especially classic slots). You will find dedicated buttons for this. If you’d like to read more information about the slot or check the rules and how much each symbol pays, there is a button for that too.

What was the first slot game?

The first slot game was called Liberty Bell and it was invented by Charles Fey in 1894.

How do you win on slots?

Slots are games of chance. You trigger wins by landing sets of matching symbols in particular places on the reels (e.g. paylines, vertical or horizontal lines, clusters, etc).

What are special slot symbols?

Special symbols can either payout more or help you generate payouts. The most common special symbols are wilds (can replace other symbols), scatters (can trigger free spins), and multipliers (can increase your prizes).

Can you play slots on the phone?

Yes, you can play slots on all devices for maximum mobility. At LeoVegas, you can play slots on your smartphone directly from the browser or via our dedicated app.
