Online Casino Reviews

The purpose with Casivo is to make sure you end up playing at the right casino for you. Within the UK, we can find hundreds of different casino sites where some are more suitable for beginners, others for high rollers or for those who prefer to play via their smartphone or tablet. However, there are some guidelines we use to review all casinos before we publish them on or our site.

When looking for the best online casino there is, we first pay a lot of attention to security concerns making sure that financial transactions and sensitive customer data are managed correctly, that the UK Gambling Commission licenses the casino and that the site is overall legitimate.

After that, we carefully read through the casino’s terms and condition to make sure that the casino does not have any requirements that are difficult to understand or that in any way might ruin your experience.

Furthermore, we inspect the casino sites technical capabilities. By that, we test the sites loading time, explore the site’s selection of slots and verify that the most common payment methods are in place.

Of course, bonuses are also carefully reviewed where we put a lot effort into creating an understanding of how good the bonus actually is by looking at the welcome offer including both deposit bonuses and free spins. Another thing that has been quite important is the wagering requirements that sometimes can be a bit hard to understand. For your own sake, it is always good to read the terms and conditions for each casino you sign up to. Further, we will also check how frequently and what type of campaigns the casino hands out on a regular basis. On our site you can find a list of casinos we recommend, where you can use the filter function to find the right casino just for you and your needs.

Casino Bonuses

As a casino player, there are few things that are better than a good casino bonus. However, it can even for experienced players be a bit difficult and time-consuming to identify and compare different bonuses.

As a first step to guide you within the land of welcome offers and bonuses, it is important that you look at the entire bonus offer and focus on the percentage match of a deposit bonus rather than how big it is. When looking at casino commercials, it is common that the casino site only promotes their total bonus not taking into consideration how much or how many times you need to make a deposit. Hence, it’s hard to realise that a single deposit bonus of 200% up to £1000 is much better than four deposit bonuses matched by 50% up to £2000.

Something else that is of high importance when evaluating a bonus offer is the wagering requirement. More or less all new casinos have the requirement that you must wager your bonus money before you can withdraw them. Otherwise, it would be possible to deposit money, claim a bonus and withdraw everything without playing, simply put a bit too easy. A reasonable wager requirement is somewhere around 35 times the bonus money which means that about 50% of the bonus money will be converted to real money you can withdraw just like it was your own.

Several welcome offers also include free spins that are free tries on a pre-determined slot machine with chances to win real money. In most cases, the free spins have the same wager requirement as the deposit bonuses.

To summarise, we recommend choosing a casino site with a welcome offer that matches the deposit bonus with a high percentage and also contains free spins, everything to a low wager requirement.

Online Casino UK

If you are a fan of online slots and is playing from the UK, you have more options of slots and casino sites than you possibly have time to play. Back in the days, slots used to be called one-armed bandits due to the iconic lever placed on the side of the machines you can find in land-based casinos around the world. Today, slot machines, which in some cases also are called fruit machines, are digitalized and have become very popular to play online at different slot and casino sites.

In most cases, slots are produced and distributed to a casino by a game provider such as Microgaming, NetEnt, IGT, Bally amongst others. The game providers create all graphics, mechanics and different features for the games, which they then lease to the casinos. It is very rare that casino operators develop slot games themselves why you often can find the same games regardless of what casino you choose to play at.

However, not all slots are the same and vary a lot both regarding how much and how often you can win. Further, not all slots are spinning reels where all you need is three similar symbols in a row. Today, some slot machines are more similar to video games using top modern graphics and technology to entertain you as a customer. Such slots, often called video slots also offer more combinations of winning lines that create more possibilities where you can win money.

To win big money, as you may know, jackpot slots are what you should be looking for in the first place. In the UK you can find a wide variety of so-called progressive slot machines where several casino sites are linked to the same machine. For progressive slots, every failed attempt to win results in increasing the jackpot even further.

Conclusion is, that if you are looking for the best online casino possible, make sure to verify that they work with high quality game providers, offer good slots and that there is general welcome offers to claim. For more information about a specific casino site, dig deeper into our casino reviews.

Mobile Casinos

Today, more or less all casino sites are adjusted to be as good on smartphones and tablets as they are when playing at a computer. Several of the casinos also have apps in App Store and Google Play possible to download. Downloading apps makes the entire casino site load much faster where also the entire interface gets better as its completely developed for mobile usage. Playing from the UK, all you need is a stable Wi-Fi or 4g connection, and there will be no problems to play wherever and whenever you want.

Live Casinos

Nowadays, technology has gotten so far it is possible to play various casino games towards a croupier that is streamed live via video. Live casino, as it’s called, is getting more and more popular for every month and it is easy to understand why. Playing for instance Roulette or Blackjack where you can see all the action live simply gets more entertaining than playing towards a computer. For social players, it’s truly amazing since you also can chat with the dealer or the other players around the table.

Questions & Answers

Why should I trust Casivo?

Casivo is run by a team with vast experience from the gambling industry. By that, we have developed our own framework to make casino reviews as objective as possible. All the reviews you can find at Casivo are tested and verified before recommendations. If you have any complaints or questions, feel free to contact us.

What is a wager requirement?

A wager requirement is a tool used by most casinos to prevent fraud when it comes to bonuses and free spins. Simply, what you need to do is to wager your bonus money before you can make withdrawals. For a bonus of 100% up to £100 with a wager requirement of 35, this means that you must wager 35*100 = £3500 before you can cash out the bonus money. Observe however, that you always can withdrawal your real money.

How much is a casino bonus worth?

A casino bonus normally works the way that you get your deposit topped up with a certain percentage. The extra bonus you get is to consider as bonus money, which you often have to wager. With a wager requirement of 35 times the money, about 50% of the value gets converted to real cash. However, only 20% of the bonuses gets converted due to that some players win really big.

What is return to player on a slot machine?

First off, return to player, often called RTP is how much a player can expect to get back from a slot machine in the long run. For a normal slot machine, the RTP is 96%. This can be compared to the NetEnt slot Blood Suckers that has 98% in RTP or the classic casino game Roulette that has 97,3% in RTP.

What is a progressive Jackpot?

Progressive jackpots are sometimes called pooled jackpots. It works in a way that several players from several casino sites play to win the big jackpot, which often exceeds several millions. Every lost bet from any player, are further contributing the raising the jackpot.

Are slot machines rigged?

No. Slots are rarely developed by the casino sites themselves and can not be controlled or adjusted in any sense by a particular online casino. Instead, slot machines and other casino games are developed by game providers that are under regulation by the UK Gambling Commission to ensure that the pay-out ratio and other factors follows the rules that are stated.

Best Slots

High Roller
Why Bonzana?
Bonzana by Big Time Gaming is popular among high rollers and VIP because of the high volatility and big winnings. If you want the possibility to both bet big and to cash out even bigger, this is the most recommended slot machine!
Why Starburst?
Using your smartphone or tablet to play we recommend the Starburst slot which is one of the most popular slots also when it comes to handing out free spins. The slot is developed with a complete mobile first approach and was released for mobile phones before they had a desktop version.
Why Rainbow Riches?
Rainbow Riches is one of the worlds most popular slots at both online and land-based casinos. The slot where you should look for Leprechauns is a slot where winnings are very common but a bit lower compared to other slots making it very suitable for beginners.
Why Mega Moolah?
By far the slot machine that has made most slot players to millionaires. The Microgaming jackpot slot is in the Gunnies world record book for handing out £13,213,838 to a lucky player from Leeds playing at BetWay. Maybe you will be the next winner?

 High Roller Slots

As a high roller, we expect you to be or about to be a VIP member of the casino site you are playing at. By that, we can assume that you receive special treatments from the casino regarding customised bonuses, tournaments, and free spins. Hence, you want the possibility to wager a lot of money on the slots you are playing. By that, you should focus on slots with high RTP (return to player) and ignore features such as graphics, bonus rounds or other cool effects. Simply put, your focus should be to wager a lot of money, converting your VIP-bonuses while chasing a big win.

For high rollers, the volatility in the slot, i.e. how balanced the winnings are should be medium to high. The reason for that is that most of the high rollers want to win big and therefore should play slots with the possibility to get high winnings.

Beginner Slots

If you are new to online casino, you should play slots where you have a high probability of winning, so the start gets as good as possible. Hence, you should choose a slot with low volatility, which means that winnings can be rather low but instead very frequent.

To see the best of what casino sites can offer, we also recommend that you begin with slots that have cool graphics where scatters, bonus games and wilds are frequently used. Why not begin with anyone of those slots that is based on TV-series or Hollywood movies, as they often tend to have cool bonus games and graphics. When getting free spins from the casino sites, slots like this are very common.

Mobile Slots

When choosing a mobile slot machine the main thing you should look for is the slot’s loading time. If it takes an unreasonable long time to simply load the slot that indicates you will face even further problems while playing. Another important feature for a good mobile slot is the navigation, an area where it can differ a lot between different games. The games we recommend in this category are games created with a mobile first approach by the game provider. By that, everything is developed with a mobile focus including bonus games, navigation through all the settings, loading times for all elements and features. Today, some slots are possible to download as apps, so your chance of winning money are just seconds away.

Jackpot Slots

All casino players sometimes dream of winning really big. Dreaming about how one would react, what one would buy or how life would change if winning a jackpot. At most casinos, you can find several jackpot slots where we recommend to look for progressive jackpot slots which mean that the same slot is correlated to multiple casino sites creating pots that often exceeds £10 million that can be won in just one single spin. These slots often have several jackpots, i.e. small, major, mega that you can win. This may feel like a consolation prize despite the fact that smaller bonuses often exceeds tens of thousands in winnings. If you have never tried a jackpot slot before we recommend you to try at least once just for the thrill you get!


Casivo supports responsible gaming

Problem gambling can happen to anyone and compare to other addictions, it can often be difficult to know if someone has a problem or not. However, problem gambling can have some side effects that stretch further than just financial troubles. Common signs to look out for is if you or someone close to you spend too much time playing at online casinos, if the person gamble for increasing amounts of money, lies about their gambling situation or borrows money for playing at casino sites. Hence, we always encourage our visitors to only play for money they can afford to lose. If you feel that you need help, the National Gambling Helpline is free to call on number 08088020133.
