What is the minimum age for playing in an online casino?

The minimum age to play at an online casino is 18 years old. However, if your country’s laws stipulate a lower minimum age, you must adhere to those laws.

How can I register at an online casino?

Registering at an online casino is usually a very simple affair, something you can do in under five minutes. For the majority of casinos, all you need to create a casino account is a valid email address and your personal details. Later on, such as when requesting a withdrawal of funds, you will be asked to show some proof of identity.

What documents are necessary when signing up in an online casino?

You will not need any documents to create a casino account. However, when it comes to requesting a withdrawal of your funds or any other sensitive functions, casinos are legally bound to follow KYC procedures. KYC stands for ‘Know Your Customer’ and ensures that casinos do their utmost to prevent their services being used for illegal activities. You will be asked to provide proof that you are who you say you are and that the money you are using is indeed yours. Utility bills, a driving license or other similar documents will be requested. All you need to do is scan the relevant paperwork and send it to player support.

What kind of casino games can I find in an online casino?

Casinos are constantly growing their games libraries and new types of games are being released all the time. Some frequently appearing casino games are slots, jackpots, table games (such as craps, roulette, baccarat, and blackjack), as well as live casino games, which includes the live streamed participation of a real live casino dealer. You can also find games such as bingo, scratch cards and arcade games at online casinos.

Who do I contact when I have a question in an online casino?

Online casinos know that keeping players happy is the key to a good business-customer relationship and they strive to offer resolutions to problems as quickly and conveniently as possible.

Where can I check which countries are eligible to play online casino?

Yes. This information is usually found in the casino’s terms and conditions. If you are not sure whether players from your country are allowed, you can always get in touch with the casino’s customer service in order to clarify.

Some might not be a fan of the wagering requirements and prefer to play with their own money. Casinos bonuses can be a fun way to play longer with, but some players may not like having their money tied down by wagering requirements. Online casinos should always give the option to opt-out of bonuses and a casino’s customer support service should be able to give you more information on this if it is not immediately clear.

Online Slots


Are there free casino slots?

Many casino slots allow players to play for free, using the Demo or Free Play mode. This means that you can play the game without contributing your own money and also means you cannot win any money either. Demo mode is ideal for players who want to try out a slot to see if they like it, before investing any of their own funds. It’s also a great way to explore all the game features for free.

What kind of casino slots exist?

Online casino slots can be categorised by a number of different features. Slots can be jackpots, have 3 reels or more, can be high or low limit. Slots can also be classified as fruit machines, 3D or video slots. They can also have varying numbers of paylines, from just one to hundreds.

What is a progressive jackpot?

A slot is called a progressive jackpot when the prize pot grows each time players do not win. Essentially, players contribute to the winning pot as they play until someone wins. At this point, the jackpot is reset and begins to grow again as players continue spinning. Jackpots are hugely popular with casino players as some can reach prize pots of millions.

How do you choose the right slot?

This depends on a number of factors. These include the size of your available bankroll and the type of game you enjoy playing. There are thousands of slot games out there, each with its own theme and features, so finding the category of game you like will help you find similar titles to try. Higher RTP slots will suit a player with a smaller budget

What is the difference between a video slot and a normal slot?

Most modern slots made today are video slots, as they include graphics and design that sets them apart from the relatively plain layout of reel slots. Video slots also usually include features that enhance the gaming experience, like sticky symbols or free spins. Reel slots do not include such features and usually have 3 or 5 reels - video slots can have more or fewer reels.

What are classic slots?

Classic slots refer to slots that are inspired by the original slot machines, often found in bars and land-based casinos. While they are completely modern, with randomised technology and a fully digital interface, they present the player with a game that is visually very close to the one-armed bandits of the past.

What is the difference between a video slot and a jackpot slot?

The term ‘video slot’ refers to the format of a game while ‘jackpot slot’ refers to its payout style. Computer generated games that simulate reels with symbols on them can be called video slots. Indeed, most jackpot slots are also considered video slots for this reason. However, games that include a jackpot feature, local or progressive, are called jackpot slots in order to differentiate them from non-jackpot video slots.

What is RTP?

RTP, also known as volatility, is a percentage value assigned to a game and determines the frequency with which the game pays out. Games with a low volatility or RTP will pay out more regularly than one with a higher RTP. Essentially, low RTP games pay out small amounts regularly while high RTP games will pay out less often but in bigger amounts.

How much can I win per game ?

Each slot game will display the maximum win possible, usually in the paytable. This varies between games and will also be affected by the RTP value of the game. Refer to our explainer on volatility to learn about how to select games that match your play style.

Can I play online casino games with my mobile phone/tablet?

Yes! Many casinos have made their product compatible with mobile devices, as more and more players are taking up this medium as their preferred way to access online casinos. A mobile casino refers to a casino that will function properly on your smartphone or tablet. Some casinos also offer mobile casino apps for players to download.

Where can I find the game rules of a casino slot?

Casino slots come in a variety of shapes and sizes but will often follow similar rules. Find out about how an individual slot works by visiting the slot’s paytable. This will have information about all the game’s features and bet limits, as well as how much players can win through the game.

What are casino slot providers?

Casino slots require plenty of research, design and technical know-how to produce. That’s where slot providers come in. These specialised studios produce games from start to finish, taking care of the title’s appearance, mechanics, sound and visual design, game play and more.

What are the most known slot providers?

There are plenty of slot providers out there and as the industry continues to grow, we can expect more such studios to pop up. Among the most well known providers are NetEnt, Microgaming, Betsoft, IGT and Playtech, though there are many others producing quality games.

Do I lose money when my computer gets stuck during a casino game?

No. Computers can and do misbehave sometimes and online casinos know this. If a game crashes during play, the normal practice is to void that wager, returning the initial bet to the player. This also means that any bonus features triggered during the malfunctioning game or any wins made during that spin will also be rendered void.

Wagering Requirements


What is wagering?

Wagering is the amount of money you bet on a game per turn, whether that is a spin on a slot game, a hand of blackjack or a turn on the roulette wheel. A wager is also called a stake.

What are wagering requirements?

Wagering requirements are a form of multiplier. Indeed, they are often displayed as 30x or x30 on casino pages. This is the amount of cash you will need to bet before winnings from a bonus can be released for withdrawal.

How do wagering requirements work?

A common wagering requirement is x30. This is considered within the average range and it means that you will need to wager 30 times your initial deposit in order to be able to withdraw your winnings to your e-wallet or bank account.

Are wagering requirements also on free spins?

Yes, wagering requirements can apply to free spins, bonus cash and any other bonus feature a casino can provide.

When am I finished with the wagering requirements?

You will have fulfilled the wagering requirements when you have wagered the original amount as many times as set out in the bonus terms. If the bonus has a x25 wagering requirement, you will be free to withdraw your winnings once you have wagered 25 times your original deposit. Where can I find the wagering requirements of a bonus or free spins? The wagering requirements for any kind of bonus, whether that’s bonus cash or free spins, will be available in the bonus terms and conditions. You can also consult our casino reviews, where we display the wagering requirements beneath the bonus description

How much can I wager at a time?

All games will have a minimum and maximum limit that you can wager, starting from as low as €0.02 and going as high as the hundreds. The latter would be considered a high stakes games and will attract players with a large bankroll.

How can I see when I have completed the wagering requirements?

Once you have accepted a bonus, you can find out how close you are to meeting the wagering requirements by visiting the casino’s withdrawal page. This is where you can find out how much you need to wager before you can withdraw your funds. This is also where some casinos offer the option to forfeit your bonus.

Do the wagering requirements work for every game?

Wagering requirements are only applied to bonuses i.e. when you play games with bonus cash or free spins. If you play with your own non-bonus money, there are no wagering requirements. Many bonuses set restrictions for the kind of games the player can play with bonus cash and how that play contributes to meeting wagering requirements. For example, a casino might decide that bonus cash can only be used on slot games or only on table games and so on. A casino may also determine that a whole wager on a slot game goes towards meeting wagering requirements while a wager on a poker game will only contribute 50%. As always, it is important to read the terms and conditions to learn more.

How are wagering requirements calculated?

To calculate wagering requirements, you need two numbers to work out the math. First, the wagering requirement itself (let’s say x30). And second, the amount deposited when claiming that bonus, using the example of €50. The calculation is: Wagering requirement x initial deposit. Using our examples, that would be: For this bonus, the player must wager at least €1500 before they are allowed to make a withdrawal of their winnings.

How to beat wagering requirements?

There are a few things you can do, before you accept a bonus, to get a good deal on wagering requirements. Choose a casino that offers terms and conditions you feel are fair. Check whether there is a cap on winnings or whether you will be forced to forfeit your bonus if you choose to make a withdrawal. It is very important to note that by accepting a bonus, you are accepting to abide by the wagering requirements it sets out. Once you have accepted the bonus, you cannot opt out of those requirements, so it is a good idea to have all the information before you make a decision.

What are outstanding wagering requirements?

Outstanding wagering requirements are how much more you need to wager before you are allowed to withdraw your cash. Using the example above, let’s say that your wagering requirement works out to €1500. So far, you have wagered €1000. That means that your outstanding wagering requirement is €500 – the amount you still need to wager before the requirements are met.
