Best online casino 2018
The years go by fast, and the casino industry is growing every day. New and fresh online casinos enter the arena, and the old giants try to stay on top. This competition is excellent for players, of course. All the online casinos are fighting for your time. But how do you find the casino that suits you? This is our greatest strength here at United Gamblers. We compare the best online casinos and casino bonuses for you. On our site you can easily navigate to whatever bonus best suits your needs today.
We have high expectations for online casinos, which means that our lists are shorter than many other comparison sites. Instead of listing hundreds of casinos, we stick to those we think are most worthy. Therefore, you will be satisfied with any casino you find here.
New customers at online casinos often receive a deposit bonus that is a percentage of the first deposit. The most common is a 100% deposit bonus, but there are sometimes higher bonuses available. 200% is also somewhat common. Then there are some companies that offer 300%, 400%, and even 500% as their welcome bonus. Below we list our favourite casinos by their welcome bonus percentage, from 100% to 500%.
How to select an online casino
We help you find the best online casino by comparing the different casinos across various factors. We measure what we consider to be the most important considerations for an online casino; by comparing factors, we can distinguish the best online casino for our readers. A lot of people look out for the bonuses that the casinos offer, and thus these bonuses are an important part of finding the right online casino. That said, there are several other considerations, such as the choice of casino games, mobile availability, and overall enjoyment. It is important to find an online casino that feels right for you, taking into account everything from gaming experience to game selection. To assist you in this process we offer our ranking system, which is structured through a ranking of one to ten stars, as explained below:
- 1-4 stars: Worse than average
- 5-7 stars: Average
- 8-10 stars: Better than average
When we compare and rank online casinos, we look at the following factors.
How does the casino bonus work?
Before deciding on any online casino, it’s important to start playing it to make sure it delivers the right feeling. Casino bonuses give you a good start to play games at that casino, and offer you a chance to try them out. Basically all online casinos offer casino bonuses, typically in the form of a welcome bonus when signing up, but also bonuses for their existing customers, as well. A casino bonus means you get extra money, enabling you to play for free or with extra money based on your deposit. In order to compare the bonuses, it is important to look at how much extra money you get and what the rollover requirements are.
Example of a casino bonus:
"Get a bonus of 100% up to £100"
- If you deposit £10, you will receive a £10 bonus
- If you deposit £50, you will receive a £50 bonus
- If you deposit £100, you will receive a £100 bonus
- If you deposit £200, you will receive a £100 bonus
This means that £100 will be the maximum possible bonus. If you deposit £10, you will receive a bonus £10, for a total of £20. If you deposit £50, you will receive a bonus £50, for a total of £100. If you deposit more than £100 (for example, say £200), you will still receive £100, as that is the maximum bonus.
This is the most important factor to take into account when choosing a bonus. A matched bonus always comes with some kind of rollover requirement. The size of this requirement determines if a bonus is very good or very bad. The reason is simple: say you have received £100 as a bonus on top of a £100 deposit. If the turnover requirement is 35x (the most common), you must play for £3500 before that bonus can be converted into cash. If the turnover requirement is 70x, you must play for £7000 before you can withdraw. Quite a big difference, right?
It is also important to keep track of which games fulfill the turnover requirement. Normally, only slots fulfill the rollover requirement 100%. At table games like blackjack, your bet might only count as 10% against the rollover requirement. That means in the case of a 70x rollover requirement, you would have to play blackjack for £70,000 before you could make a withdrawal.
There are other types of casino bonuses, most notably free spins. Free spins are free rounds at a slot machine. At the vast majority of online casinos, new players receive free spins, either as the main bonus, or as a bonus in addition the percentage-based deposit bonus. Read more on our free spins page.
Rollover requirement is is the most important factor to take into account when choosing a bonus
Selection of casino games
One very important factor is finding out what games the online casino offers. Most online casinos have a fairly similar range of games, but they can differ. Some online casinos only offer slots, while other online casinos only offer roulette or card games. Here are the most common and most popular online casino games:
- Slots and free spins
- Roulette online
- Board games — Blackjack, Poker, Baccarat, etc.
- Scratchcards and Bingo
Depending on the type of game you prefer, some online casinos will be better than others. We’re here to help you find the right online casino based on which games you enjoy the most.
Playing from your mobile device is an absolute must for all online casinos. However, there are several important factors to compare between online casinos that offer their games by smartphone. First and foremost, it is important to check whether the online casino has a smooth and easy-to-use mobile platform, one that can be accessed via an app or mobile web page. It is also important to check that the casino has the same games offered on mobile as they do on the computer. The best online casinos also usually offer bonuses such as free spins for anyone who registers with their mobile app. Aside from the bonuses, we find that the ease of use and the flexibility to play from our mobile phones are important factors in our casino rankings.
Good payment methods are an important part of ranking online casinos. It is important that they offer several types of payment methods and that it is easy and quick to make deposits and withdrawals. Some online casinos offer free spins without a deposit, but most require a deposit to get a casino bonus. We believe it is essential that online casinos provide quick and easy payment methods. It should not be difficult to deposit or withdraw money from an online casino. That is why it is such an important part of our ranking to find the best online casino.
- Fast and convenient deposits and sockets
- Multiple payment methods
A good gaming experience is perhaps the most important criteria in our ranking system. After all, the reason that most people want to play in an online casino is to get a great gaming experience. The gaming experience depends on many factors. The best online casinos usually have a website that is simple, smooth and comfortable. The benefits of playing in an online casino are that you aren’t subject to long waits and that there is little difficulty in finding your favourite casino game; the online casino’s website should reflect these advantages. Good gaming experiences usually occur when online casinos have a quiet environment without screaming banners — and, most importantly, it runs without malfunctioning or crashing. These are the four factors we value most highly when comparing the gaming experience at the best online casinos:
- Smooth and easy
- Simple to navigate
- Short waiting times
- Sleek and calm environment
Good support services are an important factor for online casinos, as it is essential that players are able to receive quick and professional help. We think it's important to be able to contact an online casino in a variety of ways. Contact by phone, email and live chat are the most common options. It is also important to note whether the customer service is available in English. Customer service should not be complicated, and the least you can ask for is to get a quick and helpful answer no matter what you might need. Ideally, customer support is available 24 hours a day, and customer service in general is something we value highly in our comparison between different online casinos. We focus on the following four factors in our rankings:
- Quick and helpful answers
- Support in English
- 24/7 Availability
The credibility of an online casino is extremely important — as a player, you must be able to trust the online casino. Credibility may seem difficult to assess, but there are actually several factors to determine the credibility of an online casino. The first thing we look at when comparing the credibility of an online casino is whether or not the gaming company is licensed for casino games. Playing at online casinos from the EU, for example, means we can rely on them to follow strict rules. The reimbursement of an online casino is also a factor we compare; even though most online casinos have similar repayment rates, they do vary somewhat. Credibility is a very important factor when comparing the best online casinos.
It becomes especially important with newer online casinos, which have both advantages and disadvantages. The advantage is that you have more companies to choose from, but the downside is that several of these new casinos are unreliable. Many online casinos are just bluffs or scams. Be on the lookout for any warning signs that seem suspicious. This might include how the website is designed, unusual language, or a strange claim regarding their bonuses.
Here at United Gamblers, we list only the serious companies. So if you choose one of the online casinos we have in our listings, you’ll know that you can trust them. There are never any guarantees, but we have thoroughly reviewed all of our listed casinos.
To create an overall assessment, we review all the factors that create a good online casino. The best online casino has to be good on all points — it is enough that an online casino is bad in just one criterion for it to potentially devalue our overall assessment. For any online casino that we rate highly, you can be sure it is one of the best casinos out there, although it is important to find a casino that suits your particular desires. We hope our overall assessment of online casinos can help you find the right casino for you.
Play at the casino — online
Playing casino should be seen first and foremost as entertainment. As we all know, the "house" always wins, and you as a player must be aware of this. Online casino games are now more popular than real casinos, and the reason is simple: The ability to sit home on the couch and play any casino game smoothly and easily, from either your computer or mobile phone, has made online casinos extremely popular. As a customer, you have hundreds of online casinos to choose from and thousands of casino games to play. Below we mention some of the most popular casino games available online.
Slot Machines & Slots
The most popular game at online casinos is slots. This casino game stems from the slot machines that became popular in the United States more than 100 years ago. Today, you can play slot machines everywhere from cruise ships to restaurants and casinos. It’s one of the most common games and you can play thousands of different types of slots in casinos all over the world. Slots are a very simple casino game where you try to get various symbols on a single line. The game is similar to a lottery where the refund is usually around 92-96%. You choose how much you want to bet and the type of slot game you want to play. The gaming casinos at online casinos are developed by well-known game developers like NetEnt, Play'n Go, Quickspin, Microgaming, etc.
Jackpots are what attract so many people to slot games. The Mega Fortune, for example, is known as a progressive slot, where the jackpot is constantly growing until someone wins the jackpot, which can be hundreds of millions of dollars. Many online casinos often offer free spins on slots as a welcome offer, giving you the opportunity to test-play slots online for free. Below we list the most popular slots and slot machines.
- Mega Fortune
- Hall of Gods
- Gonzo's Quest
Playing a table game online sets you at, of course, a table where you can play a game with or without other players, as well as a dealer. What makes table games unique as opposed to other casino games is that table games are largely based on skill. In table games like blackjack and poker, you can train yourself to win an advantage against the dealer and reduce the casino's advantage through skill. Today you can play table games online at most online casinos, where you also have the opportunity to play live. Playing live means watching a real dealer through a webcam, giving you the feeling of being in a real casino. Below we list the most popular table games online.
Games include all the other offerings of casino games available at online casinos. Games include casino games such as the slots and table games mentioned above, but also hundreds of other types of games. Many online casinos present their own unique games that differ from other online casinos in order to stand out. You are often given the opportunity to play on free money games so you can learn how the different casino games work before you start playing for real money. We recommend that you always start playing for free money until you have learned the rules of the casino game.
Casinos don’t do everything by themselves. Typically, they hire game developers to create their slot machines or other casino products, such as table games or Live Casino. Several of the prominent game makers are Swedish companies, such as NetEnt, Evolution Gaming and Yggdrasil.
Other major game manufacturers:
Casino bonus without a deposit
A casino bonus without deposit requirements is also relatively common. It means you get free money for registering, although usually in the form of free spins or other types of bonuses. So "free money" can be a little misleading, as you can’t take the money directly. Online casinos can’t give away money without having at least some requirements for its customers.
Most commonly, casinos offer free spins as a bonus that doesn’t require a deposit. It's a simple way for the gaming company and the player to try each other out. The gaming company gets to show that they offer a really good service, and the player gets the chance to try it while also having the opportunity to win real money.
Obviously, as a customer, you should always be aware that there may be different requirements for any winnings on free spins — the conditions are a rule rather than an exception. The most common rollover condition is 35x your winnings from free spins, but it varies from online casino to online casino.
Casino Bonuses Without Turnover Requirements
It is very unusual to have a bonus without turnover requirements, but some casinos will offer it. It’s basically like a free bet within the betting system: You get a certain amount (the free money) to play for, but it cannot be taken out. Only the winnings can be taken out as cash.
What are free spins?
Free spins are the most common form of bonus that online casinos offer. Free spins are offered both as a welcome bonus for new players and as promotions for existing customers. Why? Free spins at online casinos are simple and easy to understand for customers, and it's also just a very good kind of bonus. Most of us play casino games for that special kick, and nothing delivers quite like the slots.
To compare internet casinos and get your free spins today, check out our list of online casinos.
What are free spins?
Free spins are free rounds on slot machines. Instead of paying with your own money, you get a spin that is worth a certain amount. Thus, a free game, or, in the case of slots, a free spin.
Completely free spins — that is, free spins without deposit — are a promotion that many online casinos offer. But why would they offer free spins without demanding anything in return? It’s about letting you try out their product. They trust that you will appreciate the free game, and thus they hope to keep you as a customer. Furthermore, winnings on free spins usually have rollover requirements.
How does an online casino work?
Most online casinos buy their casino games from game developers who work solely on casino games. An online casino game works largely by a random generator that gives the player certain odds. All casino games include a certain amount of random chance and variance where the casino always gives itself a certain advantage. The exact advantage varies from game to game.
How do you play in an online casino?
First you should look for an online casino that suits your needs. If you do not know how to play the various casino games offered at the online casino, we recommend you start by playing for free money before you play for real money. Online casino games are usually very quick to learn, but it is necessary to know the rules of the game before betting real money.
How many online casinos are there?
There are very many online casinos in the market. Not all, however, are serious companies. We list only serious and well-respected online casinos.
Which online casino is the best?
The question of which online casino is the best is like asking which came first, the chicken or the egg? In other words, there are no correct answers here; the best online casino varies from customer to customer. If you are only looking for slots or only looking to play live poker, there will be two different online casinos that will cater best to your needs. However, most online casinos are very similar to each other and offer the same kinds of casino games. Often the biggest difference is the environment and theme of the casino, and it's up to you as a player to decide what you like the best.
Which online casino has the best payouts?
Most online casinos have similar payouts, and there is no specific online casino that offers better payouts than any other. It would be impossible to calculate an exact payout rate for any online casino since each casino game has different payout rates. For example, different slot machines can vary in their payout percentage. It’s important to look this up before you start playing a casino game at any online casino.
Do you have to pay taxes at online casinos?
Generally, you do not have to pay taxes on winnings at an online casino. You should always look up where your online casino has its licence. If you play an online casino within the EU, you do not need to pay taxes on any winnings. However, if you play an online casino outside the EU, your winnings may be subject to taxation. Most online casinos on the market have their licence in Malta, which belongs to the EU, and therefore you do not have to worry about paying tax on your winnings.
Should I play slots or table games?
It is completely up to you. However, if you make use of a casino’s bonus, keep in mind that table games often do not count as much towards your rollover requirement.
What are rollover requirements?
A rollover requirement means that you must play a bonus a certain number of times before the bonus money is converted into cash. Without a rollover requirement, an online casino would not be able to award bonuses.
