• License: every online casino you see on our pages operates under a license from UKGB. This makes sure they follow the strictest guidelines in terms of security and financial transparency.
• RNG and Fair Games: all slots run on math systems governed by algorithms that generate random results. They are called Random Number Generators and they determine the outcome of every single spin. These are monitored by UKGB and there is no way for online casinos to rig them.
• Fast and Secure Withdrawals: are you worried that a big win can disappear in thin air? No such thing can happen, licensed online slots sites will pay your wins fast, within 1-2 working days, depending on the payment method you chose.

Not satisfied with the protection the Gambling Commission ensures you? Look a step further and you will find third-party organizations, like eCogra, which monitor Online Casinos and slot providers alike. They add a layer of security to your gaming experience, and you can be sure nobody is cheating.

Now you know how online slots generate random results and Gambling Authorities create a perfectly secure environment for gambling real money.

Expert Reviews of the latest Online Slots

How do we do that?

Everyone has a different method, here at ColossalSlots.com we like a hands-on approach. As soon as our team of experts knows about a new release by one of our favourite providers, we immediately try the demo game they provide us. Of course, we like the thrill of playing real money in a trusted online casino better, but at an early stage, online slots might be available in demo version only.

Usually, it takes us a minute or two for understanding if a game will be worth our time (and yours!) or not. We have reviewed hundreds of games and we know when something is good or not. Keep reading and find out what we look for in online slots.

RNG, Licenses, and Fair Games

Are online slots rigged? This is a question many land-based slots fans ask themselves. At the same time, a general sense of distrust towards online games is still shared among older players, despite the security of online gambling systems.

How do online slots work and how can you make sure they are not designed to steal your money? 

The answer is simple: the online gambling industry is strictly regulated. Every country has its own governmental institutions, creating the grounds for a secure gaming experience. These institutions hand out licenses to online casinos that are 100% trustworthy and respect strict rules in terms of security and customer service.

Some of the strictest regulators around the globe are the UKGB, the Malta Gambling Authority, AAMS in Italy and the many state-enforced authorities in the US and Canada.

Best Payout Online Slots

Are you looking for slots with a high payout? The best payout slots in the UK can be discovered on our site, as we like to find out everything about new games. You will find here a selection of slots with high RTP, games that offer a high return to players.

For those new to online slots, RTP is an acronym for Return to Player. To put it simply, this variable indicates the mathematical percentage of wins a player has on a certain number of spins.

This is one of the most important factors for deciding whether a new online slot is worth your time.

The higher the percentage, the better! This is because a high RTP indicates higher chances of hitting winning combinations during your session.

Feature Buy / Bonus Buy Slots

Invented by Australian provider Big Time Gaming, Feature Buy/Bonus Buy Slots have already become a must among pro players. How does this work?

These games have a functionality that allows players to instantly access the free spins feature. If you ever played slots before, you know that the game is indeed about waiting for the feature to happen. Sometimes the wait can be quite long, hence the possibility of triggering it by simply hitting a button is a juicy one.

However, the possibility of hitting the special feature comes at a cost, sometimes up to 100x the stake (or more). This is the reason why the feature has been banned from some jurisdictions (e.g. the UK) among many controversies. Keep reading if you want to know more about Bonus Buy Slots.

High/Low Volatility Slots

Another important factor, when it comes to understanding online slots, is volatility. This is another mathematical variable, indicating how often you will win and what in what way.

To put it in a simple way, this is how it works:

• Low Volatility: you will win small sums quite often.
• High Volatility: hitting a win needs a higher number of spins. However, the prize will be higher as well.

Some players prefer to enjoy their time with multiple smaller wins. Others prefer to try their luck and spin for a long time for hitting a big win. That’s a matter of taste.

Cascading Reels Slots

Cascading Reels slots are those offering tumbles, also known as avalanche feature.

This reel modifier is incredibly popular among players thanks to online slots such as Gonzo’s Quest and Megaways Slots. One of the most important features in these games is indeed cascading reels, which are triggered after every winning reaction.

Symbols sitting on a payline explode after a winning combo is created. This way they make room for other symbols to fall on the reels. New symbols create a new possibility of hitting a win, without you spinning the slot again.

If you want to know more about cascading reels and the different ways they are used in online slots, we recommend you read our guide to Cascading Reels Slots!

Slots with innovative engines

If you are already involved in the world of online gaming, you might have heard of Big Time Gaming, one of the most innovative slots producers globally. They are the inventors of revolutionary games such as Megaways™, one of the most famous slots engines ever.

In the past few years, we have seen the rise of Megaways™ Slots and many other games which offer cutting edge technology for your entertainment.

Here are some of the most interesting slots engines that you might want to try:

• Megaways slots: this is surely the most popular engine for online slots right now. Developed by Big Time Gaming, the series f ground-breaking slots offers up to 117.649 winning ways and many special features.
• Megaclusters slots: you remember cluster pay games (something like Candy Crash?) Well, if you liked those, you simply can’t miss these games.
• Megapays slots: in this kind of game, innovative technology is used for creating a new gaming experience. This time the revolutionized feature is the progressive jackpot.
• Megaquads slots: this time BTG has implemented d a new way of playing those games with 4 different slots in them. thanks to this special engine you can get up to more than 1 million winning ways.
• Infinity Reels slots: developed by ReelPlay, this kind of game has infinite win potential and a x888 jackpot. A must for those who love innovation and big wins.

Slots with Progressive Jackpots

We are among the biggest fans of progressive jackpots. This is one of the most exciting features for online slot lovers. We have heard stories of progressive jackpots in movies and books, they trigger our imagination like nothing else.

On top of living in our collective imagination, progressive jackpots are a reality when it comes to online slots. You can find many true stories about people who bet few cents to became rich.. in just a spin!

How do these slots work? Very simply, they collect a little percentage of every bet of every single player spinning the game. Subsequently, they collect the total amount in a single pot, which of course results in the big jackpot.

There are several famous slots working this way: Mega Moolah, Divine Fortune, Mega Fortune, and Arabian Nights are just some of the most popular in the UK. With these games, a handful of lucky players won a fortune while betting a few cents. Online slots with jackpots are the ones that can provide a top adrenaline gaming experience!

New mobile slots at Colossal Slots

Nowadays all new online slots are developed for mobile. New mobile slots are not a thing anymore, we just give for granted that your gaming experience will happen on a mobile device. This is what developers and designers are working towards. Playing on smaller screens has never been more rewarding.

The best mobile slots are the ones that create the perfect environment for you when you decide to access your fav online casino via smartphone or tablet. We are talking about games that deliver the perfect gaming experience on smaller screens, something that is possible since a few years only.

On your mobile, you can enjoy games that evoke the quality of gaming environments (yes, we mean stuff like WoW) thanks to flawless animations, complex imagery, and fantastic soundscapes. We believe this will get better and better with time – but we believe there is a lot to enjoy right now.

Strategies for winning more at Online Slots

As we all know, every activity which involves gambling is governed by luck, and luck alone. This is especially true for online slots, which run on an algorithm that generates random results.

There is no strategy for winning with online slots. It simply does not exist, or the whole business would be rigged. These games are 100% based on luck. Everyone claiming they have a system for securing a win at online slots is lying. They don’t have it, they are just trying to cheat players.

Play Slots with our Free Demos

On ColossalSlots.com, you will have the chance of trying for free the slots we review. We strongly encourage you to do so!

By playing the demo version of online slots, you can have a clear idea about the game you are about to play. You can learn how it works, try special features and bonus rounds. Most of all, you will see if the game suits your style, falling in love with a slot is so important.

We also use demo versions of games for our reviews. We do so in an early stage of our reviews when the providers have not yet released the official version of the game to top online casinos. Sometimes we can have a sneaky look at games before the general public, this way we can write reviews in advance

Slingo

Slingo is one of the most popular online games in the UK. Nobody in the industry is surprised about that, as it is a fantastic game matching the fun of online slots and the excitement of Bingo!

We think this is one of the best new online slots out there, surely a unique type of game that is meant to entertain players of all kinds. Slingo is fast-paced and highly rewarding.

With more than forty games available and many more on our way, we cannot recommend Slingo more. Read our reviews and find out if this is something that might be interesting to you.

Bonuses: how to choose the best one

Everyone is different, not only in life but also in their entertainment choices. That’s why there are many choices available and you can choose the one that suits you best. Bonuses are great because they mean having more money to play with.

Let’s have a look at the offer that might be the perfect Casino Bonus for Online Slots:

• Free Spins: this is a very good one for slot players. Lots of fun with free spins at your favorite online slots.;
• Match Bonus: this is a promotion that doubles or triples your first deposit. This results in a bigger bankroll and more hours of fun.
• Cashback Bonus: we love this bonus so much, we now play only in online casinos offering it. At the end of each day, you get a certain amount of your money back. This way you can play more tomorrow.;
• No Deposit Bonus: this promotion is much beloved by newbies, as it allows them to play with a certain budget – no need to deposit a single cent in real money.
• VIP Rewards: this is a program designed for high-rollers. If you are one of those players, we highly recommend you chose a casino that treats you like a king.
• Loyalty Programs: if you are a regular somewhere, make sure you sign-up for this.
• Special Promotions: every top online casino offers special bonuses and promotions for its regulars. Make sure you check them out, they can be very profitable.

How do Bonuses Work

There are some common misconceptions about bonuses. Let’s get it straight: bonuses are no real money given to you as a present. They are promotions designed for improving your gaming experience.

They work under a lot of rules and restrictions:

• Wagering requirements: almost every bonus has high wagering requirements, usually in the range x35-x45. This is the reason why we recommend you use it for fun only.
• Time limits: many bonuses work within a certain window of time. Be attentive especially with match bonuses and special offers.
• Different kinds of bonuses: dozens of bonuses, dozens of online casinos. Everyone offers something slightly different, make sure you understand the promotion in detail before you sign up.

We highly recommend you check the terms and conditions of every bonus you are interested in. This way you will know in advance what is in store for you.

Bonus or not? some players prefer avoiding bonuses altogether. There are many reasons for this, the main one is being forced to follow restrictions as the ones above. you could prefer being free to play real money with no hassle. Both options are good, it depends if you prefer freedom or a higher bankroll to play with.

Payment Methods: the most popular ones

Bonuses are great when you start playing. However, if you want to play real money the important step is getting on with your first deposit. We already covered how online casinos guarantee your security. Let’s see how deposits and withdrawals work.

Online casinos offer a multitude of payment options that guarantee immediate deposits. You can think of the main ways you have for paying online in stores and e-commerce sites, protocols are the same.

Let’s see different payment methods you can use:

• Credit Cards: these are the most common way of immediately getting a balance on your online casino account. All slots sites by now accept Visa, MasterCard, and the most popular credit/debit cards.
• e-Wallets: PayPal, Neteller, Skrill, and many other electronic wallets can be used for an immediate deposit on your account. Check the casino you’re interested in for more details, they might have restrictions on the ones they accept.
• Trustly: this is a new payment method which is getting more and more popular. Highly recommended for those who want to start playing real money in seconds, registration gets just so quick.
• Bank Wire: there are traditional ways of depositing money in your account. They might not be fast as lightning in recharging your account, but you can always rely on them.

Withdrawing your Wins: how to do that

When it comes to payment methods, the most interesting bit comes when you need to withdraw real money wins from your account.

This is usually done through the same payment method you selected for your deposit. This is what we mean: if you deposit real money with PayPal you will receive your wins in the same PayPal account. This might not be the case for every single casino, we recommend you check your options.

On top of that, what is interesting to understand is payout speed. High quality online casinos process your wins quite quickly, meaning you can enjoy them in 1-2 working days. It used to be a much longer process in the past, and some online casinos still have longer processing times.

Goes without saying, on our site we recommend online slots sites with the highest payout speed. We test them all and select those offering very short times for you to receive their money.

Slots Providers: Cutting-edge technology and Gaming Innovation

Another crucial factor when reviewing online slots is providers. As you might know, there are companies that create slot machines and all other games you can find in online casinos worldwide. They produce the games, and in a second step, the games are distributed to online casinos.

This is the reason why you can find the same games on different online casino sites. Popular games, for example, Gonzo’s Quest Megaways, Divine Fortune, or Starburst can be found in most slots sites.

As you can imagine, every provider of slots has its own style, which has an impact on the general gaming experience of final users (we are talking about you, and us).

there are some providers that have a reputation for their ground-breaking products, for example, Big Time Gaming. Others are known for producing blockbusters that created huge hypes in the online gambling market, let’s say NetEnt and Microgaming.

We believe the style of different producers of games has a huge impact on the final product. We know there are some companies we like better than others, and some we prefer to avoid altogether. These are the reasons why it’s important to know who makes your games and how.

Top Providers at Colossal Slots

As you might have understood, online slots are produced by creative studios which then distribute their games to top online casinos around the world.

This is a highly creative and highly remunerative job, that’s why the competition between these companies is incredibly high. Not bad for all of us slots fans, as we can enjoy new innovative releases every single month.

We already mentioned Big Time Gaming, the Australian software provider which invented Megaways Slots, but also other innovative engines, such as Megaquads, Megaways, and Megaclusters.

There are more important slots providers out there that constantly create interesting titles. Some of these are established ones, some others are new players in the market, making an impact thanks to their dynamic structure and innovative ideas.
