Dynamic Casinos Listings Through CasinoRank

We pride ourselves on having released CasinoRank, the most advanced casinos listing system around. Its complex algorithm considers all of the factors surrounding each casino, then updates the list accordingly on a monthly basis. In addition to basic facts like Flash support, banking versatility and customer service quality, the volume and severity of complaints filed against each casino is also considered. Understandably, CasinoRank considers certain factors more important than others. In essence, it holds the same priorities as the average player.

Please note that we keep casinos with a history of fraudulent behavior in a separate section. Therefore, all online casinos on this list should be safe choices, and you will find that casinos towards the bottom do not offer as many features as those closer the top.

More about Online Casino Reviews

An online casino is a service available on the Internet that allows its customers to wager money on games of chance. The online gambling industry was one of the first to be established on the Web, and it has grown at a steady rate as new technologies have emerged. Today, hundreds of online casinos are available, powered by a variety of software companies and backed by numerous management groups.

Compared to most online industries, casinos are relatively unregulated. The industry relies on a purely capitalist form of self-regulation that stems from the affiliate-style advertising used to promote various casinos. However, these measures do not forcibly prevent fraudulent casinos from engaging in stall tactics or nonpayment; they merely serve to guide players to sites with a clean history.


Although not under much regulation, online gambling is restricted to varying extents by some governments. The United States and France are two countries that often face issues when playing online, but there are others too. Many software providers and licensing jurisdictions will prevent players from certain locales from registering accounts. The subject of online gambling legalization is an ongoing debate with numerous factors involved, including civic values, problem gambling and protectionism.


Online casinos began using simple HTML code with JavaScript. As computers have advanced, so have the quality of casinos. The predominant form then came as downloadable casino clients that use computing resources to run the games. With the recent surge in Web-focused and mobile technology, Adobe Flash is now becoming the preferred method for playing online casinos.


Online casinos vary with the number and type of games they offer. Currently, the most popular and prevalent style of game is the online video slot. These games are based on video slots seen in brick-and-mortar (land-based) establishments. Some of them are even exact replicas of these games. Other games seen are three-reel slots, card games, dice games, roulette, video poker and fixed odds games.

Most casinos obtain licenses from third parties to create their library of games. There is a growing number of software providers. Among the most popular are Microgaming, Playtech, Real Time Gaming, NetEnt,CryptoLogic and Rival. These solutions vary with how much of the casino’s operations they control. Some simply provide the casinos with the games and leave them to create their own back end processing. Others give casinos an entire suite of products, often called a “tu­rnk­ey” provider.


As Web technology advances, online casinos are becoming more adaptable. Casinos focusing on one group of players with one software platform are diminishing. The growing instant play platform has led to a growing trend of multi-software, multi-gaming casinos that allow players to access much more entertainment on a single site. In addition to the casinos that use several different software providers, many will also include numerous other betting options like sports, poker, live gaming and financials.

Mobile Casinos

Although on-the-go gambling has been in existence for quite some time, it wasn’t until the development of smartphone technology that the industry really started to take off. Because many online casinos were already well-equipped to offer instant versions of their games, many took the task of porting several of their most popular games to their mobile casino platforms. Some of the more advanced casinos now even have a dedicated mobile page that allows players to play most games on their smartphone devices, as well as claim unique bonuses.


Many online casinos will have at least one form of a jackpot structure. Typically the largest ones are progressive in nature. Online progressive jackpots work just like land-based ones: the casino dumps a seed amount into the jackpot, and a portion of each bet every player makes on the game adds to the jackpot prize pool.

These jackpots may take several different forms. Most commonly, the jackpot will be restricted to a single game, such as in Microgaming’s Mega Moolah or Real Time Gaming’s Shopping Spree. Some jackpots are linked to a batch of specific games, often sharing a common theme. The Marvel Comics series at Playtech and the Wonders series at NetEnt are two examples of this. Rarely, there may even be a site wide progressive that applies to all games, such as at WMS’s Jackpot Party Casino.


The current world of online casinos has been called a “bonus culture”. Bonuses are the primary way by which casinos compete with one another. The most popular form of a bonus is a percentage match on a player’s first deposit, often called a “welcome bonus”. A player who takes a 100% match bonus on a €100 deposit, for instance, will begin with a bankroll of €200.

These bonuses come attached with special terms and conditions that are often the cause of disputes between players and casinos. Within these terms are playthrough (or wagering) requirements, which dictate how much and on what games a player must play the deposit and bonus before he or she may withdraw. Other terms may include time restrictions, country limitations and maximum withdrawal ceilings.

The bonuses that tend to have the most restrictions are no deposit bonuses, especially when used as a form of a welcome bonus. Because the bonus funds are accessible to anyone who opens an account, a casino will typically exercise a particularly high amount of verification and regulation of a no deposit bonus. Although there are some exceptions, the vast majority of online casinos set wagering requirements for no deposit bonuses to be significantly higher than that of their match deposit bonus counterparts. They will also almost always restrict the maximum amount of money that can be withdrawn from the bonus upon meeting the playthrough, often to 5x or 10x the bonus value.

Terms and Conditions

The vast majority of players run into trouble because of not reading a casino’s terms and conditions before playing. This is likely because many people do not actually read the terms and conditions of other online services. Nonetheless, players are strongly encouraged by both casinos and affiliates to get a good understanding of the rules behind a casinos before playing at it. If a player’s dispute is based on not understanding the terms and conditions of a casino, it is highly unlikely that it will be resolved in the player’s favour.

This is one of the biggest issues for proponents of online gaming regulation. With no overseeing body dictating what casinos can and cannot demand of their players, there is no restriction on what casinos may and may not include in their terms of service.


The success of an online casino is largely due to the casino affiliate program. Rather than running their own advertising campaigns, most online casinos offer commissions to private advertisers for sending traffic to their site. Most casinos use revenue share to pay affiliates, but some opt for a cost per acquisition (CPA) model.

The affiliate marketing model used by the majority of the online gaming industry has shaped the way casinos rise to the top or fall to the bottom. Whereas some affiliates choose casinos based solely on projected profits, most use casinos’ histories to some extent to determine whether they are a trustworthy establishment to advertise. Affiliates are also the primary source of mediation for players who are facing issues with a casino.
