How to easily find a good online casino ?

With the aim of offering detailed casino reviews and a ranking of the best offers of gaming sites, our team of igaming experts uses several essential criteria. Offer to players the best gaming experience possible is our primary ambition, which is why we only offer our community of gamblers the best online casinos on the market.

To analyze all online casino offers and bonuses, here are our 6 selection criteria.

The online casino license

So that an American online casino can appear on casino-comparatif.en he must have a legal and official gaming license. No unlicensed gaming site appears in our ranking of best casinos.

Casino bonuses and other promotions

First, we check the different offers offered by an online casino: no deposit bonus, welcome bonus, deposit bonus, contest, cashback, referral bonus and other promotions. It is essential that one of the best online casinos on the market offers comprehensive offers accessible to all players. New players or regular users should take advantage of offers to play the best casino games.

In addition, we check the relevance of promotions free casino detailing all the terms and conditions of the bonuses. Benefiting from $ 1000 free is good for players, but it is necessary to be able to withdraw their winnings. This is we only select in the best casino reviews, only sites with flexible and transparent wagering conditions.

In the terms and conditions of a top online casino, it must be mentioned the wager (wagering condition), the max bet (Maximum bet per turn / hand), the period of validity of the bonus as well as the variable conditions (Some casinos prohibit certain slot machines during the bonus, they must be mentioned in the conditions). To offer the best gaming sites, our team dissects each offer and these conditions to allow you to play serenely in the best conditions. However, do not hesitate to consult the terms and conditions of the bonuses before making your deposit to be sure that they have not changed.

The library of games offered

The quality and quantity of casino games available is inseparable from a pleasant gaming experience. To enjoy excellent gaming performance with a generous welcome bonus, you need to be able to play all of the best casino games. This is why we check every slot machine publisher available on gambling platforms.
For a reliable casino to be among the best, it must offer a whole host of interesting games: slot machine, progressive jackpot, online blackjack, roulette, video poker, bingo crash games like Aviator, live casino games (Evolution Gaming) but also sport bets if you feel like the soul of a bookmaker.

It is often much more interesting to play at an online casino that has a full list of games with a lower bonus than the other way around. For example, we recommend the best casino Las Atlantis which offers 100% up to $ 500 upon registration rather than unreliable sites like the Joka casino, which certainly offers a larger bonus, but fewer possibilities in terms of games, fluidity and security.

Quality of customer service

Online casinos are different from Las Vegas physical casinos, but on the best gaming platforms we find customer service worthy of the largest establishments in the world. Responsiveness and premium quality customer service is essential for players.

Indeed, in our Top 10 online casinos of 2021, you will only find gambling sites that support you 7 days a week. If a user, even unregistered, wishes to have details concerning bonuses, the player account, withdrawal methods or even a gambling addiction problem, live chat support must be present to respond within seconds. When we let's perform tests on the various online casinos on the market, we contact customer services to note their efficiency, the response time and the quality of the information given.

Another essential criterion to be part of the elite of casinos present on casino-comparative.en it is VIP status. Indeed, new players regularly receive exceptional offers, but the best casinos reward loyalty of their players by offering exceptional advantages. For example, on the casino El Royale VIP status gives access to a personal account manager, increased bonuses, a reduced wager as well as unique daily missions.

The terms of deposit and withdrawal of winnings

It is one of the most important criteria of this selection. Indeed, we see more and more gambling sites appearing and it is more and more frequent to see unreliable casinos also called online casinos scams. It is in order to avoid these inconveniences that the casino-comparison team.en is working hard. We test online casino deposits and withdrawals before offering them to you. We study the deadlines of these and all the possibilities of deposit and withdrawal.

For a site to be in our ranking of the best online casinos, it is necessary that he has multiple deposit methods :

• Electronic wallets (Skrill, Neteller, Paypal, etc ...)
• Prepaid cards (Paysafecard, Neosurf, Cashlin, etc ...)
• Crypto currencies (Bitcoin, Ethereum, Tether, Litecoin, etc ...)
• Bank cards (Visa, Electron or Mastercard)
• Bank transfers

Access to several deposit and withdrawal methods makes it possible to meet all player needs it doesn't matter which ones. If a new user wants to take advantage of their bonus by depositing money in cryptocurrency but wishes to withdraw their winnings by wire transfer, this should be feasible where possible.

Deadlines must also be reasonable. The best online casinos have withdrawal periods ranging from 24 to 48 hours maximum to validate payments. Beyond this period, we believe that it can become a constraint for the player.

The last modality relating to the payment which is necessary is of course the security. A quality online casino must guarantee 100% security of all transactions with measurements and SSL software last generation.

Mobile, smartphone and connected media access

Our last criterion seems to us just as essential. We live in an age where the online casino offers the advantage of being able to be played anywhere, for free and without a download. But for that you have to play on a mobile casino. The adaptability of gaming platforms is therefore our last criterion.

100% of the best online casinos in our ranking are available from all connected media : mobile, smartphone, IOS, Android, Tablet, computer Where Mac, as long as you have access to an internet connection, you will be able to enjoy yourself against croupiers or on slot machines.

If you want to enjoy many games anytime and anywhere, it is first and foremost necessary to choose a site that has a mobile version. The site must be responsive. If not, when you try to play games on your laptop, the resolution and display of the content will not be adequate at all.

Players who love casino games can rejoice because most online platforms offer the different variants to their community of players in order to enjoy all their favorite games, craps, Sic bo, poker, bingo, Baccarat, gambling. , scratch games, etc. - on tablet or smartphone.

Casino-comparison.fr offers you to test the latest slots for free on your mobile phone or the free game of your choice. On our site, all you need is an internet connection and a browser to access casino bonuses, free spins, etc.

Allocation of casino ratings and reviews

Once we have been able to verify all the information and criteria of an online casino, our experts are able tocomplete and rate the gaming site concerning. This note then allows us to achieve a high-performance ranking of the best internet casinos. Our lists and reviews are regularly updated to remain the most useful for our community.

What is a bonus offered on registration ?

Online casinos, different from land-based casinos like those in the USA, Belgium, Switzerland or Canada, offer unique advantages, including the famous casino bonuses.

Thanks to our ranking of online casinos, it is possible to benefit from best casino bonuses on the web. As soon as the account is created, players can access various offers. We find 3 types of welcome gifts accessible for registration, which have different operations and conditions.

The no deposit bonus

No deposit bonus casino is a unique offer. Rather rare on gaming sites, this promotion is accessible as soon as the player account is created. In the form of free slots spins Where bonus money offered, the free bonus can be activated directly or require validation with a bonus code (Promotional code).

This bonus allows you to play for free and even withdraw earnings. It also helps tbuild a new machine slot or a new casino game without spending a dime.

Welcome bonuses

The welcome bonus is aptly named. Just like the no deposit bonus, it is a gift from the best online casinos when a player registers on the platform. It is often presented as a percentage "100% up to $ 500" for example. This means that if the player deposits $ 500 on the site he will be able to benefit froma bonus amount of money up to 100% of his sum up to a maximum of $ 500 on his player wallet.

Referral bonuses

Sponsorship is a very effective technique to gain new customers. The operation is relatively simple: imagine that you are a gamer and that you recommend the site to a friend. They register by following a sponsorship link that you sent them beforehand and make a deposit on the site in question. The establishment will offer you a reward for providing it with a new customer.

How does the payment of casino winnings work? ?

Many new players believe that the payout of winnings is done as quickly as in land-based casinos. It's wrong ! Remember that online casinos cannot pay you in cash. Therefore, the delays are more important depending on the chosen method.

Why casinos take a long time to pay ?

If you choose to get paid in bank transfer, the average lead time is around 2 to 5 days and varies depending on the casino but also your bank. This period may nevertheless be shortened depending on the methods chosen. Electronic wallets like Skrill, Paypal or Neteller allow to clearly reduce payment time since they are almost instantaneous (From the moment the casino validates your winnings). It is therefore important before choosing your casino to consult the terms and conditions relating to payment and opt for a site that is committed to making rapid payments (2-3 days maximum).

Warning : before playing with real money, take the time to learn about the withdrawal methods offered by the online casino.

Cryptocurrency casinos like Las Atlantis

These are quite simply online casinos that do not only use current money but also and above all cryptocurrency such as Bitcoin.

What are the best Bitcoin casinos ?

In recent years and the exponential development of cryptocurrency and virtual currency, we have seen the appearance of many bitcoin casinos. These gambling establishments now offer the possibility to pay with crypto wallets or to buy cryptocurrency directly. Originally initiated by platforms like Bitcasino and Slots Empires, we can now find many prestigious online casinos providing their players with deposits and withdrawals in crypto-currencies. We find among the best online casinos accepting Bitcoin and other crypto-assets:

• Las Atlantis
• NevadaWin
• Mystake

What is an electronic wallet ?

An electronic / digital wallet, also called “E-Wallet”, is a secure virtual space in which you can store: your banking information, your debit and credit card data. These different pieces of information are of course encrypted for security reasons. When the holder of this electronic wallet wishes to make a payment on a website or an application, he can choose to pay via this wallet which will provide the payment information in a simple and very fast way. Among the most famous are: Paypal, Neteller or Skrill.

The advantages of using an e-wallet

The main advantage of the e-wallet is that it greatly facilitates online transactions, which saves you time. Thanks to it, you can easily make the payment of online purchases in just a few clicks and you will no longer need to encode all the digits of your bank card as well as the verification data.

In addition to offering more speed, security is also reinforced. When you pay for a product online with your bank card, you must send all of your banking information to the merchant site.

The electronic wallet is a very good way to be able to deposit money quickly, efficiently and securely on your favorite online casino sites.

Play for free on many online slots

For beginners who are not yet comfortable playing for real money, there are free casino games. For example, it is possible to play a game of free roulette or poker games at casinos without downloading or registering, often with a fairly large game library. Play free games is a good way to familiarize yourself with the different types of games available and practice before playing in real mode.

What is a slot machine ?

You don't need any special skills or detailed guides to be able to play slot machine gamess. Just insert money or tokens into the machine to try your luck. The principle is simple: after inserting the money into the machine, the computer activates the rotation of several rollers (often between 3 and 5) which each have a series of symbols. The player wins if he obtains a well-defined combination of symbols. The result obtained is totally random, quick and easy to understand.

The notion of jackpot is very important because slot machine games offer a progressive jackpot which is in fact a system of jackpots allocated to slot machines linked together. These progressive jackpots can be offered on online or terrestrial slots. To hope to win a progressive jackpot, players must wager the maximum number of credits or coins allowed by the machine. The more time passes, the more the jackpots will reach huge sums. Some lucky people have become millionaires overnight thanks to this system of progressive jackpot.

Before playing slot machines that feature this progressive system, there are a few important points to consider. First of all, it is important to know what software powers the game and to know the reputation of the manufacturer. A crucial factor to take into account is the wagering limit on these slot machines. As players have to make the maximum bet to qualify on each Spin, this can be a costly affair. It is also a good idea to pay attention to the machine's jackpot amount, as this can vary widely.

What is Live Casino ?

the Live Casino offers you an exciting online gaming experience with real dealers. Play against live bank dealers ? It's entirely possible. The goal is to try to create an immersive atmosphere for online gamers who want to enjoy the comforts of their home. A casino game is broadcast live via a streaming video link from a real table. Online players can play the games on their computer and communicate with the dealer through the chat function. THE'interaction with live dealers makes you feel like you are at the casino table. There are casino tables that use a special camera to create a virtual casino. You can for example play high definition immersive roulette. It brings you even closer to the real casino experience because you can see the ball at close range and in slow motion until it comes to a stop.

Since this is a game method that requires a fairly complex technical set-up, not all games are available live and the offer is often limited to Blackjack, to the Roulette as well as Virtual baccarat.

Discover the new live game: Crazy Time

Crazy Time is a live game developed by Evolution Gaming released in 2020. The game revolves around a wheel that includes 54 sections of which 45 represent multipliers (1, 2, 5 and 10) and 9 give access to 4 different bonus games. As with most games with a wheel, players can bet on the expected outcome. If you bet $ 5 on 5 and the wheel lands on a 5, you will receive 5 times your bet amount. It goes without saying that the higher the number, the less it appears on the wheel. These are the numbers that are the most profitable.

You can also bet on one of the 4 mini-games which serve as joker : Corner Flip, Cash Hunt, Pachinko and Crazy Time.

The game is presented as a real TV show with dynamic animators who make the experience hyper interactive and captivating.

What is "RTP Casino" or the payout rate of a slot machine ?

The payout rate of a slot machine or the "RTP Casino"(Return to Player) represents the amount that a slot pays back to players over a large number of spins, usually expressed as a percentage. For example, a machine with a redistribution of 93% will return $ 93 for every 100 $ who is invested in it. This piece of information therefore explains how much you can expect to lose or win by playing on a well-defined machine.

It is important to note that this figure is calculated on the basis of a very large number of laps. So over a short session of a few dozen or a few hundred spins anything can happen, which is exactly what makes slots so exciting.
