Based in Waukegan, Illinois, Williams Interactive or WMS is one of the most famous and longest operating casino software developers in the world. With their hands in every aspect of the industry from classic slots to advanced mobile games and innovations of all sorts, WMS have created a name that few in the industry can match.

Williams Interactive were among the first companies to introduce slots with multiple paylines and reels and with symbols from various other brands, starting with Monopoly. As the industry grew, so did the impact of WMS on the overall world of casino gaming.

WMS owes a large part of its success to brick and mortar casinos in the USA using their branded machines, but as online gaming became a major thing, WMS moved into this arena as well, and quite successfully. WMS have created a large number of fantastic slot titles aimed directly at online casinos and later for mobile casino platforms and social networks as well.

Thanks to all these influences, many online casinos have decided that WMS is a fantastic partner to work with, which is why you will find their games available at many online casinos, a list of which you can find right here.

It is difficult to say which WMS games are the best per se, but the reality is that their video slots library is quite extensive and includes a large number of titles. Games like Big Rex, Casino Island, Exotic Treasures and Knight’s Keep each include their own gameplay mechanics and unique ways of determining winning paylines, which results in interesting gameplay each and every time.

On the other hand, WMS have also been involved with the development of many games that use famous TV brands to appeal to the general audience. Games like Mad Men, The Simpsons and Star Trek all aim specifically at the fans of the popular TV shows and were a big hit when they were released.
