Many people out there may look at online slots and not understand how people can enjoy them.

Modern online slot games are also full of opportunities to win free spins, some of which even come with the added bonus of including a multiplier for your winnings. Slots are easy to play and have the potential to change your life forever, especially when we start talking about progressive jackpot slots, which could see you winning a multi-million-pound jackpot and riches beyond your wildest dreams.


Sometimes you might just feel like playing an online slot, but you don’t want to worry about making a deposit and spending any cash, or there may be a new slot that has caught your eye, but you want to try it out before spending any money. The good news is that any online casino worth its salt is going to allow players to try out its library of games for free. Obviously, you won’t keep any of the winnings, but it’s a good way to get familiar with new games and their bonus rounds, or a way to relax and have some fun. If you want to start winning real money, you’ll have to deposit cash into your account and start wagering for real.


If you want to try out slots for a first time, or you are playing at an online casino for a first time, then the chances are you’ll be eligible to receive a bonus. More and more online casinos these days are offering ‘free‘ or ‘bonus‘ spins to new players as a welcome deal. These are spins on a leading slots game that you don’t even have to pay for!

Some sites let you keep the money you win as part of a free spins deal, but other expect you to meet ‘wagering requirements‘ before you can cash out. If, for example, a casino has wagering requirements of ‘20x‘ then you have to place wagers totalling twenty times your winnings before you can cash out.

Other bonuses are available to new slots players too, such as a first deposit bonus. With a deposit bonus a casino will match or even double the amount you deposit as bonus cash. Note that bonus cash is always subject to wagering requirements in some way or another.


Some online casinos will offer you a free spins bonus even if you’re not willing to (as yet) make a deposit of your own. One such casino is the patriotic All British Casino where you can get ten free spins just by signing up with them! Note that any winnings from your no deposit free spins are capped at £100, and you must wager your winnings thirty-five times over before you can cash out.

With most free spin offers your freebie spins are typically worth around £0.10 each, but that’s not the case at VIKS Casino. On your second deposit here you’ll receive twenty ‘mega spins’ on the classic NetEnt slot Gonzo’s Quest. You may ask yourself what’s so ‘mega’ about these spins? The answer is, they’re worth an amazing £1 each. Winnings from mega spins must be wagered thirty-five times before you’re able to cash out.


There are many different companies out there who design and develop slot games, so finding them isn’t difficult at all. However, you want to have the best possible experience while playing, so you’re going to want to keep an eye out for the biggest and best developers. This will also ensure that you’re playing at a reputable online casino, as these companies will only work with regulated casinos. Different internet casinos will have different software providers. Some may exclusively use one developer while others might have several providing the games.

Whether you are playing a 3-reel single-payline game or a 5-reel 25-payline slot, the outcome of the spinning reels is always random. The best online slots UK mimic the features of real machines, just as you’d find in Las Vegas, and run almost exactly the same way. There are no hot or cold cycles, and you need to be made aware that every game is different, meaning that each game has different rules in which they play by, offering different bonuses and special rounds.


1. Microgaming

Easily one of the most popular and recognisable game providers in the business, Microgaming has set the bar for the industry, thanks to its range of titles and the broad reach of its collaborations through its platform, Quickfire.

It is also one of the oldest game development studios around, claiming to have created one of the very first online casinos, back at the dawn of the internet in the early 1990s. Since then, Microgaming has shifted its business fully into game development and there are very few online casinos out there that do not host their titles.

Microgaming’s most popular title is also the one that pays out generous winnings – Mega Moolah. This savannah-themed jackpot paid out close to 50 million pounds in 2017 alone and the average win is an eye-watering 4 million GBP – it’s no wonder this one’s a crowd-pleaser!

The game consists of four progressive jackpots, starting with the Mini and followed by Minor, Major and Mega jackpots respectively. In terms of features, players should keep their eyes peeled for the lions (Wilds) and headhunter trophies (Scatters), which, in combination, can trigger free spins and more chances to multiply your wager.

2. NetEnt

Launched in 1996, NetEnt has been in the casino games business for over 20 years. In an industry with such a great degree of competition, that is no mean feat and NetEnt has held its position as a top developer assiduously.

NetEnt titles can be found in hundreds of online casinos and some often stick exclusively to NetEnt games, such is their strong appeal to players. This game studio has created seminal titles like Starburst and Gonzo’s Quest, a firm favourite with players and with casinos, who often include these games in bonuses and promotional campaigns. NetEnt has also created a live casino games platform, delivering HD live dealer blackjack, roulette, baccarat and poker to thousands of players worldwide.

Aside from the two slots mentioned above, perhaps the most recognisable NetEnt game would be Mega Fortune. This jackpot regularly rewards winners with multi-million pound paydays, the largest on record clocking in at €17,860,868 (that’s close to 16 million GBP).

But NetEnt is not just about jackpots. As a game studio, it is constantly generating creative themes for its titles, including a series based on music (NetEnt Rocks! trilogy), TV (Dallas, South Park) and film (The Invisible Man, Jumanji, Planet of the Apes).

3. Playtech

If we had to pick a title for Playtech it would be ‘King of Acquisitions’ – this brand knows the value of joining forces with other creative players in the field. Playtech launched in 1999, releasing its first online casino game two years later.

Since then, Playtech has gone from strength to strength, in part thanks to its constant push towards innovation and creative evolution. With hundreds of titles under its belt, including slot, live dealer games, sports betting, and more, Playtech has certainly moved with the times. This game provider also supplies casino solutions to big names like Ladbrokes, William Hill and others.

Brands that now fall under the Playtech umbrella include BGT, Aristocrat Leisure Limited, BetBuddy and QuickSpin – familiar names with their own loyal following and unique design contributions.

One purely Playtech title to try out is Goblin’s Cave. It may not look like much, with its simple 3×3 layout but it does boast an insanely high RTP – 99.32% according to some sources. It has only 3 paylines but is surprisingly generous with the game features, including Wilds, a mini game and a Hold feature that lets you keep the symbols appearing on the lowest payline across the three reels.

4. Yggdrasil Gaming

Yggdrasil has been making increasingly large ripples across the casino world since its launch in 2013. This young (for now) casino has wowed players with its unique creative flair, evident in the slot games they launch.

This studio pays meticulous attention to detail, and this approach is evident in the games they produce. Everything from the characters to the music to the animation reflects the Yggdrasil aesthetic, resulting in games that feel well put together and, most importantly, are extremely fun to play.

It’s safe to say that Yggdrasil is one to watch and this innovative game studio is sure to present us with some fantastic titles in the future.

A good example of a solid Yggdrasil game would be Jokerizer. It displays the game provider’s style perfectly, with a coherent gambling experience to be had every time. As with most Yggdrasil slots, the 10 paylines go in both directions across the reels (right-to-left and left-to-right).

There are only 7 symbols, including the Joker. That Joker is the key to triggering a Mystery Win, which rewards players with a x100 multiplier on their original bet.

You can also choose to play with Jokerizer mode, which lets you double your wager with your winnings in return for a chance at seriously boosting your bankroll.

5. Betsoft

You could say this UK casino game provider has seen the evolution of the industry, having opened its doors in 1999. All that experience has certainly been put to good use over the years, as Betsoft has remained a major player in the game provision industry.

This studio’s specialisation is 3D games, a genre that has seen continuous interest over the years as animation techniques and tools have improved. The cinematic quality of Betsoft’s games is the hallmark of this developer.

Perhaps one of the most interesting games out there at the moment is the Betsoft title Good Girl, Bad Girl. Players can choose which of the two characters they’d like to stick with, each influencing the game in a different way.

Side with the Good Girl to have pay lines go from left to right, while volatility is lower. Pick the Bad Girl to have paylines go from right to left and volatility is higher, with a lower chance of winning but with the rewards being significantly higher. A great game for players who like to change up their level of risk within the same game.


If you consider yourself an expert slots player, then you might want to up your chances of winning big by playing at a slots tournament.

32Red Casino is a great online casino for slots tournaments and they offer a daily freeroll tournament in which you can win a share of $250! You start off with a set number of coins, and at the end of the specified play period the person with the most coins remaining is declared the winner!

If you want to win big using an online slots game then you need to be playing lots of slots with progressive jackpots. The best games with progressive jackpots are made by Microgaming, so you’ll need an online casino with plenty of Microgaming games, such as Dunder Casino. Get spinning and keep your fingers crossed – remember the record payout from a progressive jackpot slot is nearly €18 million!


With mobile technology becoming more and more important each year, mobile casinos have become an exciting new way for players to enjoy wagering on their favourite casino games in 2018. Mobile Casinos have become an important part of an online casino’s portfolio, because of the convenience that they offer the players.
