Many of the people who play at online casinos don't think about where the games come from. They log into their casino of choice, choose a slot game, and hope to win, all while having a great time.

But those people who think that individual casinos develop their own games, or that the software is just written by some anti-social programmer in some basement somewhere are neglecting the impressive achievements of the software developers who have actually poured huge amounts of time and energy into creating truly wonderful games.

Playtech, along with its rival Microgaming, is one of the powerhouse software providers of the online casino gaming world. They don't just come up with games; they provide the entire software engine that some of the biggest and best casinos on the internet run on. And once they've done that, then they design not dozens, but hundreds of fun, entertaining, and profitable games that will keep players coming back over and over again.

To see the enormous selection of games that Playtech offers its casinos, head to any of the biggest Playtech casinos out there, such as the world famous William Hill Casino which is an extension of the William Hill sports book business. These online casinos don't have 50, 100, or even 200 games, they have hundreds of games which are all original and entertaining.

One of the things that Playtech has become famous for is its selection of slot machine games based on the Marvel series of comic books and films. Playtech has taken the time and effort to make every single Marvel slot unique. So not only does The Avengers look different from X-Men, it has an entirely different game mechanism, different bonuses, and different ways to win.

The Marvel slots are not the exception, but the rule. Playtech has also developed thrilling and original progressive slots and even the 3-reel classics have their own unique flavor. Playtech continues to go beyond expectations and that's why they have the best collection of slots around.
