Finding the Best Slot Sites
In order to help you narrow down your options, there are a few things that you should be on the lookout for when choosing a new place to play:
- Number of Slot Games – This is an obvious one. The bigger the collection, the more slots you will be able to enjoy.
- Variety of Slot Types – Make sure that the collection is diverse. Ideally, it will contain classic and video slots, and games with a huge range of themes.
- Variety of Software Providers – Each developer has its own style. This means that if a site offers games from multiple developers, you can be sure that the collection of slots will be varied and interesting.
- Bonuses – Check that the slot site offers bonuses that are suitable for slot players. Also, be sure to review the terms and conditions to ensure that they are reasonable and fair.
- Mobile Play – Today, many people enjoy playing on their smartphone or tablet device. Check that the slot site you are interested in is mobile friendly so that you can enjoy your favourite games while on the go.
- Free Play Demos – Many of the top slots sites will allow you to play the game for free in demo mode. This is a great way of finding new favourites without risking your own money.
- Casino License – Ensure that the casino is licensed in your jurisdiction. This way, you can be sure that it is a safe and fair place to play.
- Easy Banking – Make sure that the slots site uses payment methods that are convenient for you. These could include bank cards, e-wallets such as PayPal, or a variety of other methods.

Different Types of Online Slots Explained
Today, there are many different styles of slot machines, each of which offers a different playing experience and different types of features. Ultimately, which you play will be a matter of personal taste, but it is important to understand the difference between them. Here is a brief rundown of the various types of online slot machines.
- Classic / 3-Reel Slots – A classic slot is generally considered one that has three reels. Today, many classics have exciting graphics and bonus features, but traditionally they were simpler games.
- Fruit machines – This is actually a British term for slot machines. However, it is often used to refer to traditional games that use symbols such as cherries, lemons, watermelons, plums, and so on.
- Multiline Slots – These types of slot machines offer many hundreds or even thousands of ways to win. As a result, payouts are won as long as enough matching symbols land on consecutive reels, without the need to worry about paylines.
- Video Slots – This is a term used for slot machines that are more modern. Traditionally, Video Slots will feature five reels with three rows of symbols visible on each reel, and they will offer a variety of bonus features.
- Grid Slots – Sometimes also known as Arcade Slots, these slot machines do away with paylines entirely. Payouts are won by landing horizontal and/or vertical clusters of matching symbols, and the games nearly always feature tumbling or cascading reels.
- 3D Slots – These can be any style of slot machine, but they will feature exciting 3D animations and graphics.
- Progressive Jackpot Slots – When playing a progressive slot, a portion of each bet is contributed to a jackpot fund. This way, the jackpots can grow to be worth millions.
- Penny Slots – These games are designed to be cheaper to play. Often, they will allow bets as small as 1p per payline.
Real Money Slots and Free Slots: Pros and Cons
When you explore online slots, you will very often see games advertised as either Real Money or Free Play. Other terms used to mean the same thing include real play and demo play. Regardless of the terms used, the difference is both clear and important. When playing Free Slots, you will not be betting any money, instead, you will be playing with a demo balance. When playing Real Money Slots, you will be betting your own money. The big difference is that when playing Free Slots, just as you can’t lose any money, you can’t win any either. With Real Money Slots, you both risk your money and have the chance to win more.
There are advantages and disadvantages to both. Free play is a great way to explore a game, discover what features it has to offer and see if it is a game that you would like to play. However, the real excitement comes with real money play as it gives you the chance to hit some enormous payouts.
The Leading Online Casino Games Developers
Today there are a huge number of developers producing online and land-based slots. Each developer has a distinct style, and their games offer something a bit different. For instance, NetEnt is one of the big developers, and it is best known for its stunning graphics and for integrating bonus features into the base game. Another example is Microgaming; they were behind the first online casino and the first networked progressive jackpot. Other major developers include Playtech, Play’n GO, and iSoftBet. Each one offers something a little different, and all of their games are worth exploring.

Are the New Slots Sites UK Mobile Compatible?
Today, nearly all online slots are developed using HTML5 technology, which makes them fully mobile compatible and ensures that they can be loaded directly in web browsers. The games are carefully optimised for mobile devices, ensuring that they look good on smaller screens and that the controls are easy to use. Some games will even offer a ‘Lite’ mode for those looking to save data. A few online casinos will offer dedicated mobile apps, but the vast majority have mobile-friendly websites, making it quick and easy to play from almost any internet-connected device.
What Are Slots Tournaments and What Can You Win?
In recent years, online slots tournaments have become hugely popular with players, and you can now find them at nearly all online casinos. They are essentially leaderboard competitions that see players compete with one another for the chance to win some exciting prizes. The tournaments are often game specific and may run across one casino or be networked across many. The more spins a player plays on a slot, the more points they will earn and this way they will climb up the leaderboard.
The prizes on offer will vary according to the tournament and casino. It is common to find slots tournaments that are free to enter and give players the chance to win free spins. Some slots tournaments will also have buy-ins, and these may offer more exciting prizes such as gadgets, cash, or even jackpots. For example, at Mr Green casino, you will find a huge number of Reel Thrill tournaments taking place at any given time, and they often have hundreds of free spins up for grabs while on the casino’s promotions page it is usual to find special tournaments with huge cash prizes.
Identifying the Fair Online Operators
If you are playing online slots, then it is vitally important that you know the games are fair. Slots use a Random Number Generator (RNG) to ensure that each spin will have a random outcome. When a developer applies for a license from a respected regulator, such as the United Kingdom Gambling Commission, then they will have to prove that their RNG is truly random, and therefore the games are truly fair.
A number of companies exist that test developers’ RNGs to ensure that they are honest and fair, such as iTechLabs, eCOGRA, and Gaming Laboratories International. Developers submit their games to be audited and will normally publish the results on their websites.
You can also often find certificates from these testing laboratories on casino websites as well. They will also publish the Return to Player percentages, which is the theoretical percentage of the money bet on a slot that is returned to players over time. As long as you can find a certificate from one of these laboratories together with a license from a respected authority, at either the casino or the developer’s website, then you can be confident that the games are fair.
Playing Slots Made Easy
In order to get the best out of your online experience with online slots sites, you can always try and apply some useful tips and tricks to excel at your play. Here are some suggestions that might come in handy:
FAQ
Which Is the Best Online Slots Site?

Can You Play at UK Slot Sites for Free?

The games behave the same at all times, so the best time to play is when it is convenient for you. There is one exception if a slot offers a jackpot that must be won by a certain time and that time is approaching, then it is an excellent time to play, as the jackpot must soon be won.

You can trust many online slots sites, but not all of them. You can completely trust sites that hold licenses from respected gambling authorities, such as the UK Gambling Commission, as this means the games are certainly fair, and players’ money is protected.
