WMS (Williams Interactive) Slots

Published on:

Williams Interactive, better known as WMS, is a renowned name in the world of online slots. With a rich history dating back to 1943, the company has come a long way from its humble beginnings as a pinball machine manufacturer. 

Over the years, WMS has successfully transitioned into the realm of video games and slot machines, establishing itself as a major player in the industry. In the early days, WMS was known for producing classic arcade games like Paddle Ball, Defender, Stargate, and Robotron: 2084. 

These games were immensely popular in the late 70s and could be found in almost every major arcade. 

As the company grew, it eventually ventured into the slot machine market in 1994, leveraging its expertise in video games to create innovative and engaging slot experiences. 

One of the most significant milestones in WMS’s history came in 2013 when the company merged with Scientific Games Corporation. This merger allowed WMS to expand its reach and resources, further solidifying its position as a leading provider of online slots.

WMS Slots Features and Strengths

Unique Themes and Licensed Content

WMS is known for its unique themes and licensed content, which sets it apart from other online slot providers. 

One of their most popular series is the Monopoly-themed slots, which bring the classic board game to life in an exciting and interactive way. Players can enjoy the nostalgia of the game while experiencing the thrill of spinning the reels and potentially winning big. 

In addition to Monopoly, WMS has also secured licenses for other popular franchises such as Top Gun, Star Trek, and Men in Black. These licensed slots offer players the chance to immerse themselves in their favorite movies and TV shows while enjoying high-quality gaming experiences.

Innovative Bonus Features

WMS is renowned for its innovative bonus features that keep players engaged and coming back for more. One of their groundbreaking slots, Reel’Em In, introduced multi-line and multi-coin secondary bonus pay-outs, which revolutionized the way players could win. 

Another notable example is the Jackpot Block Party slot, which features a unique bonus round that offers more winning opportunities than traditional free spins. 

This innovative approach to bonus features has become a hallmark of WMS slots. The Spartacus slot is another fan favorite, thanks to its regularly triggering bonus games and free spins. With additional sets of bonus symbols, players have a higher chance of activating the bonus rounds and potentially winning big.

Progressive Jackpots

WMS is also known for its progressive jackpot slots, which offer players the chance to win life-changing amounts of money. These slots feature interconnected machines that contribute to a constantly growing jackpot prize pool. As more players spin the reels, the jackpot continues to increase, often reaching millions of dollars. 

One of the advantages of WMS progressive jackpots is that they can be linked across multiple casinos. This means that players from different locations can all contribute to the same jackpot, making it grow even faster and reach even higher amounts.

WMS Slots Weaknesses

Limited Game Selection

While WMS has an impressive portfolio of online slots, it’s worth noting that their game selection is somewhat limited compared to other more established providers. This may be due to the company’s focus on quality over quantity, but it could be a drawback for players who prefer a wider variety of options.

Lower RTP and Higher Volatility

Another potential weakness of WMS slots is that some of their games may have lower Return to Player (RTP) percentages compared to other providers. This means that players might experience longer dry spells between wins. 

Certain WMS slots are also known for their higher volatility, which can lead to more significant fluctuations in bankroll. While this can be exciting for players who enjoy the thrill of big wins, it may not be suitable for those with smaller budgets or a preference for more frequent, smaller payouts.

Raging Rhino

Raging Rhino is a popular 6-reel slot with 4,096 ways to win. Set against the backdrop of the African savannah, this game features stunning visuals and exciting gameplay. With a variety of animal symbols and the potential for massive wins, Raging Rhino has become a fan favorite among online slot enthusiasts.

Zeus III

Inspired by Greek mythology, Zeus III is a 6-reel, 192-payline slot that takes players on an epic adventure through the realm of the gods. With stunning graphics, engaging bonus features, and the chance to win big, this slot has captured the hearts of many players.

Bruce Lee

The Bruce Lee slot is a 5-reel, 60-payline game that pays homage to the legendary martial artist. Featuring a unique Money Burst format, this slot offers players the chance to win big while enjoying exciting gameplay and visuals inspired by Bruce Lee’s iconic career.

Wizard of Oz

Based on the beloved classic movie, the Wizard of Oz slot transports players to the magical land of Oz. With a generous 50,000-coin payout potential and a variety of bonus features, this slot has become a favorite among fans of the film and online slot enthusiasts alike.

WMS Slots RTP and Volatility

WMS slots offer a range of RTPs and volatility levels to cater to different player preferences. The RTP of a slot represents the percentage of wagered money that is returned to players over time.

  • Raging Rhino (95.91%)
  • Zeus III (96.10%)
  • Bruce Lee (96.05%)

  • Medium volatility: These games balance the frequency and size of wins, offering a mix of smaller and larger payouts.
  • High volatility: These slots offer less frequent but larger wins, appealing to players who enjoy the thrill of chasing big payouts.
