Before the big bookmakers introduced us online casino gambling our experience of playing any of what we now call online casino games was confined to visiting a real casino, a bingo club or playing a slot machine wherever we could find them. Apart from perhaps one or two of the more sophisticated modern slot machines there was nothing particularly complicated about any of the equipment necessary to enable us to play these games. Transferring them to an online platform however was not quite so easy and required the expertise of specialist computer programmers to design the necessary casino software to make it happen. The decision of the leading bookmakers to expand their online sports gambling sites to include a range of gambling games was instrumental in the creation of a whole new business sector associated with the gambling industry, namely the casino software suppliers who are now responsible for supplying most of the online casino games available online. Even the traditional casino games such as roulette and blackjack which clearly did not require any original thinking in terms of the game itself, still required the expertise of the casino software designers to create the graphics we see on our screens. Where the importance of the casino software companies is most apparent however is in the huge range of slots games which form the major part of the range of casino games offered almost every online casino site. It is these online casino games that are wholly down to the skill and imagination of the casino software designers, and they are the reason why the casino software companies have become so important to the online casino sector. The choice of casino software supplier was probably the most important decision the original online casino site operators made in terms of their commercial success, and even now when the sector has expanded to include a whole range of new specialist sites the casino software remains of paramount importance. The online casinos featured on our recommended list offer casino games developed and supplied by a number of different casino software companies, but most observers would probably agree that the company which has been most dominant in the development of online casino gambling is Playtech. Originally founded in Estonia in 1999, Playtech began supplying online casino software in 2001 and was at the forefront of several innovations during the early years of online casinos. They were for instance the first casino software company to launch the live casino option in which casino games such as roulette, blackjack and more recently baccarat are streamed live to our screens from a remote studio using a real roulette wheel and real dealers. They were also the first to introduce a specialist online bingo platform and quickly followed that by also providing a specialist online platform for poker enthusiasts. In 2008 Playtech took another step towards their dominant position in the market by signing an agreement with Paramount Digital Entertainment which allowed them to use well known character from several Paramount films as themes for their online slots games. A similar deal with Marvel Entertainment the following year gave them the option to also theme their slots games on popular Marvel comic book characters. William Hill, Betfred and Ladbrokes all currently offer slots games supplied by PLaytech on their online casino sites, but Playtech is not the only successful online casino software supplier to feature on our recommended site list. Ireland’s most popular bookmaker Paddy Power for instance has always used software supplied by Wagerworks since starting their online casino site. Wagerworks was originally a subsidiary of Silicon Gaming, a well-known slot machine manufacturer, but has been concentrating on online casino software since 2005. Wagerworks slots games can also be found on the 888 casino site. Of the more recent entrants to the online casino scene, the All Irish casino has become very popular in Ireland. In this case their casino software is supplied by one of the biggest casino software specialists in Scandanavia, namely NetEnt or NetEntertainment to give it its full title. Originally established in 1996, NetEnt have established a reputation for extremely high quality graphics and their video slots in particular are proving very popular at the All Irish casino. Slots games supplied by NetEnt can also be found on a number of the other more recent specialist online casino sites which have joined our list of recommended sites, including the newest online casino to reach our screens, the Funcasino. Many of these new specialist online casinos such as CasinoLand, Yako casino and Instacasino now feature slots games from a variety of different casino software companies rather than offering casino games from a single company as was the norm in the early days of the development of online casinos. This trend has introduced many of us to a whole new range of exciting slots games, particularly those supplied by Amatic Industries. Real slot machine enthusiasts will almost certainly know many of the popular slot machine games supplied by Amatic Industries, but until now they have not been available online. The CasinoCasino site operators decided however to change that and were therefore the first online casino to give their customers the opportunity to play these iconic games online. Once again it is also possible to find some of these popular Amatic Industries slots at the new Funcasino site. The most important element of any online casino is clearly the quality and range of casino games they offer their customers, so the casino software companies will always play an extremely important role in the success or otherwise of the online casinos. That of course becomes even more relevant as we get more and more specialist online casinos coming on stream. We have not been able to list every online casino software supplier in this article, and there are many casino slots games featured on the online casinos listed on our recommended list which are actually supplied by other software companies, the biggest of which is probably Microgaming which has also been the main supplier for Ladbrokes since the early days of their online casino site.
