Online Slots

“From my long years of slotting, I would say that LUCK and SKILL are the two most important factors to win. Skill can only come after many years of experience, but even with excellent skill, no one can beat the slot without the luck! Skill can tell you if the game is playing good or bad, but only luck can determine if you win or lose.”

Why are slots so popular among gambling fans? Well, because they are fun and easy to play, and, moreover, can bring you some decent wins. You don’t need to have any special skills or knowledge but can still get a lot of money — that’s why slots are so loved by players. 

During the 7 years I spent working as a casino dealer and manager, I’ve seen all possible kinds of slot machines and can now tell a bad one from a good one at a glimpse. Now, I use this experience in my online gambling journey, which allows me to select the best slots and recommend them to you. I pay maximum attention to the fairness and payout rate of the games, as well as to their providers and gameplay. Below, you’ll find a detailed description of my slots selection criteria that I used to create this refined slots list.

You can use these criteria to find your favourite slots as well — in this case, don’t forget to share them with me using the contact form. Or, you can save your time and effort and rely on my choice of the best online slots UK.

My Criteria For Choosing the Best Online Slots 

It is crucial to understand what you personally want from a slot game before starting it. This is the only way to choose your perfect slot and to avoid any disappointment while playing it.

I usually ask myself the most important question: “What do I want to get from a slot today?” Then I can apply one of my evaluation criteria to choose a perfect casino corresponding to my mood. Let us discover these criteria and how they work.

Increasing the winning chances

To the table of contents

You can significantly increase your winning chances in slots if you know the RTP rate of the game and can compare it to its alternatives. RTP stands for Return-to-Player and shows the amount of funds you actually get from your initial investments.

RTP rate is usually shown in per cent. A good slot game often has more than 95% RTP. You can receive up to 99% RTP rate with the slot games I have collected in my list like Jackpot Jester from NextGen Gaming at Betfair Casino. Also, feel free to sort slots by max RTP and select the one you like best among the leaders.

Another way to increase your winning chances is to bet for the higher number of paylines. In other words, the more money you bet, the more lines on a slot are available for you to win. Minimal betting, for instance, suggests only one payline to play with.

Getting the sweetest bonuses

To the table of contents

Welcome bonuses have become one of the greatest features of online casinos in the UK. You would never get such sweet welcome bonuses for your first deposits and free spins as a gift in any brick-and-mortar casino. However, you also need to pay attention to wagering requirements and the Terms and Conditions for cashouts.

You can use my list of the best UK slots if you do not want to invest your own time and money in checking all of their pros and cons. For example, Mustang Gold from Pragmatic Play at CasinoEuro has 25 wager-free cash spins.

Choosing a slot from a favourite provider

To the table of contents

If you already have a favourite provider and would like to find more slot games developed by it, than I can help you too. I have a great collection of slots from different providers, and they are all at your disposal, including free casino slot games for fun within their demos.

All you need to do is to set search filters in the category of Provider. You will find the list of the most popular game providers and have the opportunity to pick your favourite one. After making this selection, you will see the list of the games from this particular provider.

Hitting the jackpot

To the table of contents

Each gambler dreams about a great jackpot. Modern online casinos give amazing opportunities to hit stunning jackpots even while playing slots.

Some gamblers suppose that a great jackpot can only be won in roulette or a card game like poker. Furious Furry Friends from The Games Company at Great Britain Casino are fighting this myth with their £400,000 jackpot!

Playing for fun

To the table of contents

If a gambler wants to play for fun or to test some slot game, he or she usually chooses the opportunity of a minimal bet. Modern online casinos like CasiPlay and slots like Cops and Robbers from Green Tube allow you to bet from £0.01.

Although minimal stakes have such advantages as the cheapest form of betting, the longest possible bankroll, the widest variety of slots to experience within the lowest price, and the best chances to unlock bigger bonuses and wins, there still are some cons. You need to understand that the minimal betting reduces your winning chances on every spin, as well as the amount of money you receive from winning. Most players find minimal bets not so exciting, and the chance of hitting the jackpot is usually not available for minimal bets.

Going big

To the table of contents

Maximum bets provide a gambler with a maximum level of excitement. If you seek something that can tickle your nerves and bring the real adrenaline to your blood, then max betting up to £200,000 by Jack in the Box from Novomatic at AHTI Games Casino is your best option to play.

I must warn the beginners about maximum bets: it is better to try out many slots for free before betting a lot of real money. My website gives you an opportunity to train your skills and gain more confidence before betting at your maximum on a real online casino.

Gambling on the go

To the table of contents

Mobile gambling develops swiftly, and online casinos respond with their mobile versions of the websites or even dedicated mobile applications. A good modern online casino must think about mobile users and represent the smooth navigation and gambling process for them.

Starburst from NetEnt at Mr Green Casino is a beautiful example of a slot game that has its dedicated mobile application with the same features as a desktop version of the game. Moreover, this is also one of the games where it is easy to use bonus money or free spins. Thus, Starburst gets the best reviews from mobile gamblers, and I can recommend it for players who like to play on the go.

Making convenient deposits and cashouts

To the table of contents

Getting your winnings as soon as possible is another important feature for any online casino. Gamblers do not like to wait, and online casinos try to make cashouts within less than 24 hours for any winnings, including slots.

Viva Fortune Casino is an excellent example of an online casino with a wide variety of deposit and cashout methods: credit and debit cards, PayPal, Skrill, and other payment methods are available here.

Enjoying retro slots

To the table of contents

Want to feel the atmosphere of the ‘80s or ‘90s with their classic slot and fruit machines? There is no need for a time trip! Modern online casinos have a wide variety of classic slots, which will give you the feeling of old-fashioned gambling machines.

Twin Spin from NetEnt at Casimpo is an amazing example of a classic slot with modern graphics. Enjoy your nostalgia with all the advantages of modern technologies!

How to choose a safe online casino 

To the Guide

There are two main things you should pay attention to:

  • UKGC license. This license is the best sign of a trustworthy online casino because it can be obtained only by a gambling house that has passed the test of the state. It is also a guarantee of protection for your rights as a player by the law of the United Kingdom.
  • eCOGRA certificate. eCOGRA is an independent agency that tests and verifies games on online casinos. Its certificate is the sign of licensed and non-pirated games within a certain online casino, and the guarantee of the slot results fairness.

Best slot machine developers 

To the Guide

The quality of your gambling experience is very dependent on a slot game you choose. It would be wise to know the best game developers whose reputation is pure and whose games bring joy for a few generations of gamblers in a row.

I have collected some examples of trustworthy game developers for you to distinguish the providers of the most popular games not only by their logos:

  • PlayTech was founded early in 1999 and has quickly become one of the leaders in the gambling industry.
  • Microgaming was created even earlier — in 1994. The developer has got the reputation of the biggest jackpot-game provider worldwide. One of the games that brought it such fame is called Mega Moolah.
  • Evolution Gaming is a company that specialises in live table games. Moreover, the game provider has vast experience in other types of online casino games: blackjack, baccarat, roulette, and so on.

  • IGT stands for the International Game Technology and works in a worldwide network of offices. The count of released games is now more than 12,000 and goes further.

Tips and tricks that DO and DO NOT work

To the Guide

Would you like to know which tricks are worth trying and which are just a kind of superstition? My vast experience in gambling allows me to create a list of useful tips and tricks for slot lovers and observe those tips, which have no practical use for you as a gambler.

So, here are some popular tricks that DO NOT actually work:

  • Looking for “hot” machines. Some beginners would love to have a simple trick for a big win. So they decide to play those slot machines that have brought a big winning to someone else. This strategy is absolutely useless because the winning chances are estimated personally for each player in an online casino.
  • Switching machines. A lot of beginners make such a mistake — they switch a slot machine whenever they lose. Simple switching of machines cannot bring you winnings. The better strategy is to learn different strategies by means of free slot games online within their demos and then choose the one you like the most to bet real money.

And now, let us discover some tricks that DO work with online slots:

  • Bet more to cover a higher number of paylines. The more paylines you have covered with your bet, the better chances for winnings you have.
  • Always manage your funds properly and know your limits. It will help you to stop betting at the right time before you lose all of your deposits.
  • Use free demos to learn the slots you are about to play with real money. My website gives you the unique opportunity to try any popular slot to improve your skills before betting real money.
  • Bet more if your goal is to hit the jackpot. It can depend on a certain slot, but usually, you have better chances to hit the jackpot with a higher stake.
  • Do not forget about welcome bonuses, free spins, and other presents from an online casino. They can significantly increase your chances for a win by means of multiple retriggering of your spins or giving you additional paylines.
  • Play online to get better RTP rates and exclusive welcome bonuses that you would never get in a traditional casino.

Most unusual video slots to play for real money

To the Guide

Let us now observe some interesting features of modern gambling machines that can give you different extra advantages while playing slots.

  • Wild Symbol. This symbol plays the role of a joker in slots. In other words, a wild symbol can change to any other symbol that brings you a win.
  • Transforming Wilds. This feature expands the ability of a traditional wild symbol to two or more symbols in a line. Different slots may have various terms for activating transforming wilds` features which make them even more unique and exciting to play.
  • Expanding Wilds. This feature brings you the opportunity to transform common symbols in a whole line and can even give you additional free spins.
  • Sticky Wilds. Correspondingly to its name, a sticky wild symbol stays still for more than one spin to give you more profitable transforming opportunities.
  • Moving Wilds. This feature also offers you multi-turn wild symbols. In this case, a wild symbol will move to a certain direction with each spin until it leaves the line.
  • Bonus Rounds. A lot of modern slots have various bonus rounds where you can win additional spins or multiply your winnings.
  • Unusual Slot Structure. Modern slots expand their features far beyond traditional 3 or 5 reels. Some of them propose additional symbols within one cell, others offer up to 3125 paylines which you can open step by step during your play.
  • Tetris-Slots. This unofficial name reflects the main feature of this slot type: the symbols of a certain type disappear from lines after you get a winning line; new symbols will fill the empty slots and can bring further winnings immediately.

Are you curious about some examples of unusual video slots that can offer additional fun with extra bonus games and chances to retrigger your spins? I have some interesting slots for you to discover.

  • South Park: Reel Chaos from NetEnt. This slot game provides you with extended opportunities for a bonus game where you will face different opponents and spin the reels to defeat them. Extra bonuses are given for each defeated enemy, and there is a special bonus after defeating all of them.
  • Aliens from NetEnt. This unique slot game is built around the original scenario of the Alien movie. You move forward with each successful spin and get better ammunition within the bonus rounds. The whole road is difficult, but the treasure is worth it!
  • Hold Your Horses from Novoline. This is a great example of a classic slot enhanced by an amazing new idea from its developers. The slot machine has five reels, but a player can get up to 10 symbols in a payline. It happens because some symbols have two horses on them instead of one. The amount of horses does not influence the payline but counts as a multiplier for your winnings.
