WMS Gaming Company History

The history of WMS began back in 1943. Initially, the company activities were not directly related to gambling and were limited to the production of pinballs. The company changed its name several times until it became Williams Electronics in 1974. From the same year, Williams Electronics began its activities related to the gambling market. The original gambling games from the company were presented in the form of arcades. Some of these games of chance are still in demand among fans of the “golden age of arcades”. We are talking about Moon Patrol, Joust and Defender. The pride of the company is also the arcade games NBA Jam and Mortal Kombat, which made a splash in the 90s. By this time, Williams Electronics had already launched the release of pinball machines. In the same decade, WMS began to manufacture slot machines. The first WMS slot, Reel ’em In, was created in 1996 and was supplemented with bonus rounds. This not only changed the destiny of the company but also influenced the development of the gambling industry. Williams Electronics was the first to start supplementing classic slot machines with different animations and bonus rounds.

Instead of continuing to release arcades, Williams Electronics has focused entirely on the production of WMS free slots, while supplementing them with the features of familiar computer games. Over time, they became known for creating games based on such major franchises as Monopoly, Men in Black, Top Gun, The Lord of the Rings, and Star Trek. These games became the basis of their activities. WMS went through a rather difficult period in 2012 when the company experienced a decline in revenue from the online casino industry, which seemed to be shrinking at the time. As a result, Williams Electronics expanded its horizons and went into mobile devices, creating games for mobile platforms, and focusing on expanding its offerings in the online marketplace. An important turning point came in 2013 when Scientific Games acquired Williams Electronics for $ 1.5 billion. To this day, the company remains the main supplier for both land-based and internet gambling markets, producing both WMS free slots and mechanical machines.

WMS Casino Software Platform

Williams Electronics is a renowned manufacturer of gambling, WMS free slots, and land-based slot machines for land-based casinos and online casinos. Initially, the main audience of WMS was US players. At this stage, the company’s international offices are located in many countries, including Australia, Canada, India, China, South Africa, Mexico, Spain, the Netherlands, Argentina, Austria, and the United Kingdom. The list of products from WMS casino is regularly updated with new names. Typically, WMS free slots are provided through instant play software. This means that to play, you just need to go to the site and start the game. Moreover, in recent years, WMS casino has been working to adapt all its games to the screens of portable devices. The company’s games have several distinctive features such as:

  • Colourful animations;
  • Guaranteed bonus features;
  • Large progressive jackpots.

The graphics of the WMS free slots are bright enough. Each WMS free slot machine is filled with animations, original characters, and sound effects. One of the things that set WMS free slots apart from other online casino game manufacturers is their names. They were one of the first companies licensed for trademarks that everyone knows and, therefore, have achieved significant success in games from the Monopoly series, as well as in The Wizard of Oz, Top Gun, Star Trek, and others. For players looking for skill-based video games, Williams Electronics has released Wizard of Oz, Top Gun, and Dirty Harry. Of course, every player hopes to win. WMS free slots feature high payout percentages, generous bonus features, and large progressive jackpots.

The first 20 free spins are credited immediately after registration, and the next 80 free spins will be credited within 2 days.

WMS Casino Games in Online Casino

With the growing popularity of WMS free slots, the demand for other online casino games is declining. Some manufacturers even choose a narrow specialty, preferring to release only slot machines for online casinos. The main area of the WMS company operations is the production of land-based slot machines and WMS free slots for WMS casinos. Nevertheless, some part of the company activity is dedicated to the production of other products for online casinos. For example, the manufacturer presented a huge line of poker games that work through the “My Poker” machines. If you choose a poker game from WMS casino games, we advise you to pay attention to Jacks or Better and Deuces Wild. Unfortunately, the manufacturer does not have any other card games at this stage. However, there are several roulette games, although more often they are presented in tandem with other manufacturers. Even though the selection of online casino games from WMS is less than that of competitors, the company still remains among the leaders among software providers in the gambling market.

However, a reform of gambling in the US is expected soon.
