Your enjoyment or lack of it at an online casino will depend largely on the casino games that you are playing which in turn is a function of the casino software which is being used. For casino games such as Roulette or Blackjack the casino software is not so important as the game is always the same but when it comes to casino slots or video slots there is a huge difference in between the offerings of the various casino software suppliers. Online casinos rarely use casino software that they have developed themselves preferring instead to have agreements with one or sometimes more of the specialist casino software developers. There are handful of major casino software suppliers such as NetEnt, Microgaming, Playtech and Wagerworks but there are also smaller players in the online casino market which you might come across such as Amatic Industries or NextGen Gaming which also offer excellent casino slots. The fact that there are far more online casinos than casino software suppliers also explains why the casino slots at online casinos often look remarkably similar and in fact often they are the same games. So for example All Irish Casino and FreeSpins casino both use NetEnt casino software and Bet365 and BetFred casino also have the same games. This in itself is also not a bad thing as progressive jackpot slots for example are contributed to by all online casinos that use the that software which enables the jackpots to grow much faster than they otherwise might with just one online casino contributing. Casino slots is very much a personal choice with the huge variety of themes and music contributing enormously to your enjoyment. Casinos.ie very much likes and promotes the casino software from NetEnt which has some very interesting and different casino slots such as Gonzos Quest™ or for something really different look at Birds on a Wire™ which can only be found at Yako Casino.
