CryptoLogic have been recognized as one of the Internets casino software leaders since they came on the scene in 1996 and has been licensed through wholly owned subsidiary WagerLogic. 1996 might not sound that long ago but in web terms these guys are very well established to give you some kind of a comparison 1996 is the same year Google was launched. CryptoLogic offer Ecash Direct of which its software has processed more than US$30 billion in secure electronic transactions. Hows that for confidence! They offer a wide variety of exciting and games and new ones are being released all the time.When you open an account with any CryptoLogic casino you will get sent your PIN and account number via postal mail. Keep this safe as you will need it when cashing out money or contacting there customer support.

They offer a great range of slots and as with all there games they try to make your casino experience as close to the real thing as possible. Which is a big part of the reason that they are the software providers behind Intercasino which has won the award for being the best online casino 5 years in a row! This award is voted for by players and last years poll was taken of over 50,000 players which makes it the biggest poll of online gamblers and thus the results the most valuable. It should come as no suprise then that CryptoLogic themselves have had an honorable mention every year since the polls began and won Silver in the category of Top Casino Software Provider in 2003 and 2004 and then finally in 2005 they won the Gold.

Microgaming are one of the leaders in online gambling software. They offer everything and for microgaming slots that means the choice of a wide variety of no download and download slots as well the popular progressive jackpot slots. They are committed to providing new easy to play and exciting games and providing the best playing experience for the player. They are regularly updating there software and these new features will automatically be quickly downloaded when you open your casino account if you are already a member of one. They offer the option to play all games for free or real money so you can test them out before playing for real with confidence.

Their new Viper software has allowed for even more exciting games to be created and for slots players this has resulted in some fantastic 5 reel 9 pay line video slots such as Thunderstruck which has 3 ways to win!

As Microgaming are so good, many casinos use there software which means many players are playing there progressive slots which makes for some huge jackpots.

Microgaming have also won the award for being the Top Casino Software provider for more years than any other casino software provider. They won gold in 2002, 2003 and 2004 and just lost out taking silver in 2005. The poll is a poll of online gamblers and the readers of online gambling magazine so it is a players poll so the results are meaningful as they reflect what players like.

Playtech was founded in 1999 and on the 28th March 2006, Playtech’s shares were successfully admitted to the AIM market of the London Stock Exchange. The company was valued to be worth approximately £548 million. The playtech.com website is very informative and you can see a full historical breakdown of how the company and its software has evolved over the years.

What we are interested in here is the fact that Playtech offers a wide range of quality online slots games in a number of categories. All playtech casinos (that we have tested) have sharp graphics and although it has never been voted higher than bronze in the online gambling magazine awards it is alway in the top 4 as voted for by the players.

The Playtech casino software has some great features many of which are unique to Playtech. So here is an overview of some of the key features Playtech powered casinos have to offer.

1. All games are available in Download and No Download Flash versions.
2. Ultra-fast login.
3. Adjustable gameplay speed, sound effects, card size, close-up slots.
4. Real-time game & transaction histories.
5. 1-on-1 live chat support.
6. "Favorites" Game Menu.
7. Autoplay slots.
8. Arcade Games.

That list is not fully comprehensive there are many more features that we could have listed but these are the features we felt set Playtech powered casinos apart from the crowd and also the features that are most likly to be of interest to slots players.

The Playtech software also boasts some really quite unique slots games such as Goblins Cave which is one of four multi spin slots with a twist. They each have the ability to hold reels after the first spin before the multi reels are spun, so similar to a Fruit Machine but not a Fruit Machine. I highlighted Goblins Cave because as well as this great take on a multi spin it also has a bonus game.

Vegas Technology is the software that has replaced OddsOn software at casinos such as English Harbour and Super Slots. In its first year (2005) the software won the award for being Top New Casino Software voted on by readers of Gambling Online Magazine.

With over 90 different games on offer and the majority of those being slots, the software could well have been created with slots players in mind. There are some unique things such as 7 Reel Slots and a number of very simple and easy to understand Multi Line slot games, which is rare as most multi line slots seem to have bonus games and wild symbols etc. So it is nice to see that they are giving players the option, and I think this would suit any player who likes classic slots because of how easy they are to understand but who might like to try the thrill of a multi line slot game without being confused with alot of extra 'what ifs'.

Of course that doesnt mean they havent created games for the hardened slots fan, they have plenty of games with wild symbols, scatters, multipliers and some great bonus games.

Plus the Vegas Technology Software (just like cryptologic) allows for the straight forward type of slot tournaments which is great for all types of slots players.

Backed by a strong back-end casino management suite, RealTime Gaming software is designed to deliver a realistic player experience. RealTime introduced "integrated" bingo, multi-player poker and system-wide progressives. RealTime provides the outside resources to aid the client in hosting, customer service, hardware selection, technical support, training and continuing education.

Real Time Gaming software is fast, clear, and easy to use. The casinos themselves are generally good bonus givers, and with the fast play it is easy to get through the required play quickly. Most Real Time Gaming casinos are okay but there are some questionable one. One very generous bonus giver, Casino Merlin, went down in early 2002 and player accounts are likely lost. So choose which RTG casino to play carefully. One inconvenience is that you have to fax in a copy of your credit card and id for a withdrawal of $500 or more. Table game limits are $5 to $500, slots and video poker take coinages from 5 cents to $5.

There are two versions of Real Time Gaming software: download and Flash.
