WMS Gaming Slots & Best Casinos

Williams Interactive, or WMS to its friends, is one of the longest-tenured software developers in the gambling world.

While WMS has been one of the top names in the iGaming and land-based casino industry since the mid-1990s, the company goes back much further to the 1940s.

Since 2013, when WMS merged with Scientific Games, WMS has operated as a wholly-owned subsidiary of SG Gaming.

As expected, considering the position of WMS in the online casino scene, there is no shortage of top-quality online casinos offering slots from this developer.

Free WMS Slots & Reviews

Given how long the developer has been creating slots for, and how many they have produced during that time, it is no surprise that the WMS portfolio has a range of different themes, designs, and gameplay options.

While it is impossible to mention all the excellent WMS slots, here is a small selection of the best.

Amazon Queen

An oldie but a goodie, Amazon Queen does not have the bells and whistles of more recent WMS slots, but this classic game still have a lot to offer, and enjoys consistent popularity as a result.

Based on Amazonian mythology, the free spins bonus round sees the highest-paying symbol pay both ways, giving the chance for some hefty wins. It may feel a little old at times, but Amazon Queen still has a lot to offer.

Bier Haus

A unique and fun slot themed around the German love of beer, this 40 payline slot has become something of a cult classic for WMS.

A colourful, beer filled design can trigger up to 50 free spins in the bonus round, with the scatter symbols that trigger the bonus round becoming sticky wilds that stay in place for the entire duration of the free spins feature.

Black Knight 2

The unoriginally titled sequel to Black Knight, this second instalment in the series has found substantially more popularity than its fairly successful predecessor.

The bonus round here benefits from a fully wild middle reel, which can remain wild for the whole of the free spins bonus, allowing for chains of wins if you’re lucky.

Double Buffalo Spirit

Buffalo Spirit was a popular WMS release, and Double Buffalo Spirit takes the concept and enhances it beautifully.

A Wild West-themed slot with 1,024 ways to win, there’s a maximum win of 250,000 coins available in this high octane slot that plays out on a 4×6 grid.

The free spins feature gives up to 20 free spins and includes multiplier wilds for the chance at some big wins during this bonus round.

Kiss: Shout it Out Loud!

WMS does not follow the path of most top-named developers by releasing numerous branded slots, in fact, Kiss: Shout it Out Loud is one of the only ones they have.

This slot based around the classic rock band plays similarly to another popular WMS slot, Spartacus.

As with many WMS slot games, the bonus feature does not trigger easily here, but it can pay off big when it does, and the soundtrack, which is exclusively made up of Kiss songs, makes the waiting a lot more fun!

Raging Rhino

A slot that has launched many a copycat from other developers, Raging Rhino is one of the original African Savannah themed slot games in the online world.

A 6×4 grid with 4,096 ways to win ensures this is an oft-paying slot that keeps players interested for a long time.

With multipliers available, and a free spins feature with a 250,000 jackpot, there’s a lot to love about this slot, and it has received praise from players and critics alike.

Zeus III

Another example of WMS improving a slot concept with every sequel, Zeus III is seen by many to be among the very best slots that the developer has to offer.

Based around the popular slot theme of Greek mythology, this is a highly volatile slot, with the bonus round not triggering often, but when it does, being more than willing to pay out big thanks to expanding wilds that can see 1,000x your bet being picked up on a single bonus spin.

The History of WMS

Williams Interactive (or Williams Manufacturing Company, as it was at the time) was founded way back in 1943, starting its life in the gambling work producing pinball machines and videogames for arcades.

Over time, the output of WMS expanded into multiple genres of video-based games for arcades and casinos, including the first virtual lottery machine for US casinos, which the developer launched in 1991.

WMS has made a big name for itself around the world, especially in Las Vegas, before the company made its first movements into the iGaming world in 1994, producing its first slots for the then embryonic online casino market.

In the present day, WMS, now operating as a Scientific Games company, is one of the biggest providers of online slot games in a highly competitive market.

Despite having a huge portfolio of games already, WMS maintain their position as one of the most prolific developers around by releasing at least one new slot into the online world every month.

WMS is an absolute legend in the online casino industry, and the gambling world as a whole. This reputation is certainly well deserved, this is a developer that has been creating new, exciting, and innovative games for almost as long as the iGaming market has existed.

With new games being released on a regular basis, there is always something to look forward to from WMS, and many players keep their eyes locked solidly on what the next addition to the already impressive and extensive WMS slots portfolio will be.
