How to Choose the Best Slots (GUIDE)

“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.

Every time I’m choosing a slot to play, I use my 6-step guide to find the best option. After playing the machines from my nominations list, you can look for new ones using my criteria. Here they are:

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

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.

1. Evaluate your chances to win

Evaluate your chances to win

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.

I have created a guide dedicated to the casinos with the highest payout rates. If you are looking for big wins, these websites might be perfect for you. The list of game titles there include both sophisticated new slots and classic and simple options such as fruity slots.

Your chances to win are high if:

✔️ many games with high RTP are offered

✔️ games with high number of paylines are available

You are not likely to win much if:

❌ the casino does not provide games from famous providers

2. Consider the possibility to use bonus money

Consider the possibility to use bonus money

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, you can get 50 free spins to spend on the Book of Dead slot by PlayNGo at PlayKasino.

You can make use of a bonus if:

✔️ it has low WR

✔️ the wagering time is more than 72 hours

The bonus is not the best if:

❌ there are tricky terms and conditions

3. Check whether the games from your favourite provider are available

Check whether the games from your favourite provider are available

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.

Game selection is good if:

✔️ products of famous providers are offered

✔️ games with high payouts are available

You will not have much fun playing if:

❌ casino offers non-licensed games

4. Take a look at whether you can hit the jackpot

Take a look at whether you can hit the jackpot

Winning a few million dollars and making your dreams come true sounds like a good plan, doesn’t it? Nowadays, everyone has an opportunity to become a lucky guy. 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! It’s worth noting that so-called progressive slots can still bring you lots of nice small wins. This means, even if you don’t hit the jackpot, you will enjoy the gameplay.

5. Make sure playing the slot is fun

Make sure playing the slot is fun

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.

🎰️ Pros of minimal stakes:

✔️ This is the cheapest form of betting

✔️ The longest possible bankroll

✔️ The widest variety of slots to experience within the lowest price

✔️ The best chances to unlock bigger bonuses and wins

🙁 Cons of minimal stakes:

❌ Minimal betting reduces your winning chances on every spin

❌ The amount of your winning is low

6. Pay attention to the maximum bet

Pay attention to the maximum bet

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 Pariplay at CampeonUK 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.

7. Test the slot on your phone

Test the slot on your phone

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. I believe that the best mobile casino slots are those where you can play with a full screen. In this case, even if your phone is relatively small, you still can enjoy betting. 

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.

The casino mobile version is good if:

✔️ it has an intuitive design

✔️ the same games are available in PC and mobile versions

Your on-the-go gambling experience might be spoiled if:

❌ crashes or freezes appear during a game

8. Consider options available for deposits and cashouts

Consider options available for deposits and cashouts

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. Speaking of deposits in slots casinos, they are usually instant.

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.

Making money transactions is going to be easy if:

✔️ wide choice of payment options is provided

✔️ instant deposits/withdrawals are offered

Deposit and cashout might be problematic if:

❌ no popular payment methods are available

Top High Payout Slots

To the Guide

Playing slots is fun. When I was a novice gambler, I enjoyed using demo versions of different game machines. Later, I switched to real money betting. At the moment, I’m mostly opting for slots that can bring me a lot of money. To select such games, I consider their RTP. In this guide, I want to share my list of slots with the highest RTP with you:

Enjoy the jungle adventure created by Playtech. Here, you will have 10 separate rows, three symbols on each. You can’t hit the jackpot but believe me, you are going to be happy with the number of your wins. 

This is a 2×3-reel, 5-line game. Although it has a simple retro outlook, playing Mega Joker is really exciting because of the frequent wins, thanks to its high RTP. 

You should certainly try this 5 reel slot with 3 symbols showing on each reel. If you like sea-themes games and getting money for playing, 1429 Uncharted Seas is a good choice. 

This slot with a ghoulish theme is a great game with 3 bonus games: Free Spins Bonuses, a Graveyard Bonus, and a Super Graveyard Bonus. The playing process will never get boring. 

Do you like cats? If yes, this slot is for you. The wicked bass lead 70s Bond era soundtrack adds some special atmosphere to the gameplay. 

Main Types of Slots

To the Guide

If you are new to the gambling world, you might be confused with the variety of casino slots games. But choosing one is going to be easy if you know their classification. That’s what I’m here for - to tell you about the main types of such games:

  • Video slots

Usually, such slot machines have around 25 – 30 paylines. In addition, bonus games are more readily available on video slot games than on other types of this entertainment. 

  1. 7s Deluxe by Reel Time
  2. Action! by Belatra
  3. Age of Conquest by Neon Valley Studios
  • Classic slots

I believe these are the best online casino slots. The majority of classic slots offer just one payline spread over the three reels, which is their main distinction compared to video slots. 

  1. Buffalo Blitz by Playtech
  2. Action Bank by Barcrest
  3. 9 Masks Of Fire by Gameburger Studios
  • Progressive slots

These are the games for jackpot hunters. If winning some crazy amount of money with just one spin is your dream, you should definitely opt for this kind of slot. 

  1. Age of the Gods God of Storms by Playtech
  2. Divine Fortune by NetEnt
  3. Fishin Frenzy Jackpot King by Blueprint
  • New casino slots

As you can guess from the name, these are the games that appeared recently. They are always fun to play since such slots are usually more innovative and have different cool features that are lacking in classic ones. 

  1. Chilli Heat by Pragmatic Play
  2. Cleopatra (IGT) by IGT
  3. Cash Volt by Red Tiger

Things to Know Before Playing Real Money Slots 

To the Guide

You need to know the features of a responsible and trustworthy online casino before entrusting your money and your pleasure from gambling to one of them.

How to choose a safe online casino 

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.

Top Slots Providers

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.:

Best Microgaming slots

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. Here are some other famous Microgaming creations:

Best NetEnt Slots

NetEnt is mostly known for its high-quality slot games. The company provides a variety of live table games, too. Vikings have brought real glory and popularity to the developer. Let me show you NetEnt slots that are worth your attention the most:

Best IGT Slots

IGT stands for 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. Don’t miss a chance to try the following IGT slots:

Best Playtech Slots

The company has managed to produce and market more than 500 games. The majority of slot variations by Playtech have special symbols such as Wilds and Scatters. I definitely suggest you trying the following creations of this brand:

Best Play'n GO Slots

The brand was established in Vaxjo, a Swedish town, in 1997. At the moment, there are more than 100 different Play’n GO slots with payout percentages ranging from 94-98% available in different casinos. I especially like the following:

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 casino slots strategies that DO work:

  • The most famous and pretty efficient concept works as follows: you start with a minimum betting amount and increase it every time you win. If the outcome is negative, the betting returns to the minimum amount.
  • Avoid progressive slots if you prefer having many small wins rather than hunting for large prizes. The thing is, the jackpot machines tend to pay less frequently, while casino online slots with smaller prizes tend to pay out more frequently.
  • 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

Video slots are perfect for playing on the go. They do not require as attention as Poker or Blackjack and you do not need as strong Internet connection as for live Roulette or Baccarat.

If you want to spin the reels when waiting in line or going home by metro, here are perfect casino slots for Android and iOS:

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.
  • Spreading Wilds. This feature expands the ability of a traditional wild symbol to several 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.
  • Locking Win. This feature brings you the opportunity to transform common symbols in a whole line and can even give you additional free spins.
  • Synchronizing Reels. In this feature, two or more adjacent reels have the same game symbols which significantly increases your winning chances.
  • 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 Game. A lot of modern slots have various bonus rounds where you can win additional spins or multiply your winnings.
  • Cascading wins. This feature is also known as “tetris-slots” and 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 GreenTube. 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.

My online casino blacklist

To the Guide

Some unreliable online casinos try to cheat on their players by creating pirated copies of the slot machines. These unlicensed copies often have a very low RTP rate or even give no chance for a win to a gambler.

I constantly check the online casinos from my list and add them to my blacklist if they start to violate the rules of a trustworthy casino. I recommend you to check my blacklist each time you are to deposit real money to any online casino. The situation can change in a matter of a few hours.

First of all, I recommend upgrading your skills by playing free slots with no download and no registration within their demos before betting real money. Secondly, there are better chances to win big if you bet more on slots.

🍒🍒🍒 How do online slots work?

Online slots usually work in the same manner as their traditional predecessors. You simply need to spin the reel and wait before the slot stops to discover whether you have some winning lines.

💸 What online slots pay real money?

Each online slot pays real money, except when you play a free demo version of it. You obviously need to bet real money to get real winnings.

⚠️ How to cheat at slots?

I strongly recommend leaving the thoughts about cheating aside. We expect trustworthiness from an online casino and should behave correspondingly.

👍🏻 How to play Vegas slots for free?

Actually, the main difference between slots in Vegas and any other slots (including online ones) is the price for tickets to Las Vegas. You can play any popular Vegas slot on my website for free within its demo version.

🔥 Which casino has the loosest slots?

Check the RTP rates of each game you play on an online casino. I do not recommend playing slots that have less than 95% RTP or do not contain the information about RTP at all.

🎰 How to play poker slots?

Poker slots differ only with the images you see while reeling a slot wheel. Try different free slots of video poker within their demos versions on my website to understand whether it is your thing.
