What are online slots?

Most people are familiar with physical slot machines. You’ll see these gaming machines in amusement arcades, pubs, bars and cafés, betting shops and casinos. Depending on how old you are, you might also know them as fruit machines or one-armed bandits.

Modern versions of these physical slot machines are generally computerised video terminals that use game software stored locally or on a remote server to run the game.

The difference with online slots is that you don't need to be in front of one of these physical machines to be able play the best slot games. With slots online, it's your phone, tablet or computer that connects directly to the games software via the internet, so you can play online slots from wherever you happen to be, whenever you choose.

How do online slots work?

As explained above, when you play online slots your phone, tablet or computer connects to the games software over the internet. The game software is held on our computer servers, but you don’t need to know that as the slots game and all its features just appear on the screen of your choose device.

An important part of the game software is a Random Number Generator or RNG. The RNG ensures that the outcome of each game is fair. When you spin the reels, the RNG software chooses numbers or symbols completely at random and independently of any previous spin.

What does RTP mean?

Three other important letters associated with online slots games are RTP, which stand for Return To Player. Expressed as a percentage, RTP is the amount, on average, that the slot game will pay out.

Starburst™ from NetEnt, for example, has an RTP of 96.09% so therefore pays out, on average, 96.09p for every £1 spent.

RTP is calculated over a long period of time and across game sessions played by multiple players. This means that over a short period of time you may not receive the RTP back yourself in return for the amount you have bet – you may receive more than the RTP percentage, or you may receive less.

What does slot volatility mean?

Slot volatility refers to how often and how much, on average, a slot pays out.

A high volatility slot pays out big wins that are spread apart. A slot with low volatility pays out smaller wins closer together. A slot with mid or medium volatility offers a win pattern somewhere in between high and low.

However, all slots can pay out a mix of small and big wins. Also, it's possible on any slot game to have a hot streak of wins or a cold streak in which a win eludes you. Where a slot game falls in the range of high-mid-low volatility (sometimes called the volatility Index or VI) is, like RTP, based on the average.

You’ll see a high, mid or low volatility rating and an RTP percentage on the game page of every slots game on this Evolution website.

Forget the jargon and enjoy the fun!

All of this talk of RNG, RTP and volatility shouldn’t obscure the fact that the majority of players play online slots because they are a great fun, are easy to play, and many of the best have strong themes or even storylines.

Of course, because these are games of chance – and because of the way our slots games are designed to be entirely fair – some players will have more luck than others.

It's that element of luck, alongside the undeniable entertainment value, that makes the very best slots so popular with players.

FAQs online slots

Our slot brands provide their games to leading online casinos worldwide. You can go directly to a selection of these casinos from the ‘Play for real money’ links near the top of every game page on this website.

Not always. Most of the slots titles on this Evolution website are available to play for free in demo mode. This will give you some great playing experience, allow you to learn new games, and to understand the paylines and the rules before taking a chance with actual money. (Of course, you can’t win any money until you choose to play for real money!)

Please note that the free demo mode is not permitted in certain countries, including the UK. If there’s no ‘play for free’ demo available to you in your region, you’ll still be able to watch a demo video of the game. This will give you a good idea of how each game works before you decide whether or not to play for real money.

Very often, yes. It's quite common that welcome bonuses are made available when you sign up to create a new account and deposit funds with an online casino. Such bonuses may not always be on offer, but if you click any of the ‘Play for real money’ links on this Evolution website, you will need to open an account and deposit some money with that online casino to start playing for real, unless you already have an account with them.

There’s no simple answer to that, although many of our titles do appear regularly at the top of the lists of best slots games ever!

Some players focus on high payout/Return to Player percentages. Some focus on high volatility games that pay out big wins or are attracted by features such as Megaways™ or free spins bonuses, or by progressive jackpots that keep growing and pay out by a specified time. Others love games within different themes that interest them or particular characters, such as Gonzo, the Spanish conquistador, who appears in various slots titles. It really is a matter of personal preference.

Megaways™ slots are games that use the Megaways™ random reel modifier, a unique slots game mechanic developed by Big Time Gaming, one of Evolution’s slots brands. Megaways™ changes how many symbols appear on the reels on any given spin to offer many more ways to win than in a traditional online slot game.

On this Evolution website you’ll find Megaways™ games from not only Big Time Gaming but also from NetEnt and Red Tiger. The majority of these Megaways™ slots titles offer an amazing 117,649 ways to win!

A slot game payline is a line-up or combination of winning symbols that appears across the reels when they come to rest after each spin. In other words, a payline is the winning positions of certain symbols that you attempt to achieve with each spin.

Paylines in slot games can come in many forms – they can be in straight lines and can also appear diagonally and in other geometric patterns. The most obvious payline is a horizontal straight line running across the reels.

At the end of a spin, if the correct symbols match a payline pattern, you win a prize. To confirm this to you, the slot game draws a line on the screen to indicate the payline that triggered the prize.

A wild symbol is a designated symbol that acts as a wild card and can therefore complete any winning payline.

When playing any slot, be sure to identify which symbol is acting as the wild. Sometimes it’s obvious because the symbol will have the word ‘Wild’ on it, but in other games it will be a unique symbol or visual connected to the theme of the game.

A scatter is another designated symbol that can show up on the reels. Usually, when a certain number of scatters appear on the reels at the end of a spin, they will generally reward you with free spins or other bonus features.

As with wilds, be sure to identify which symbol represents the scatter before you start playing.

In actual online slot games, Free Spins are a bonus won during gameplay. The bonus awards you a set number of Free Spins during your current game. In many of our online slot games you can even win further Free Spins when playing your initial set of Free Spins!

What we’ve described here are in-game Free Spins, but online casinos may also offer free spins as a welcome offer for new customers.

A progressive jackpot is a prize that keeps on increasing in size every time somebody plays the game. ‘Progressive’ literally means that the jackpot amount keeps on growing, or progressing, until a lucky player wins it. Sometimes these progressive jackpots are time-limited and therefore pay out on or before a set time.

With a fixed jackpot, the amount you can win is shown in a paytable and the amount doesn’t change. A progressive jackpot is variable and will usually result in a much higher prize value as it’s made up of a small percentage of stakes from players playing the game, or a series of linked games, at any number of online casinos.
