WMS: Best Casinos and Slots (2023)
Williams Manufacturing Company (WMS) was founded in 1943. At that time, Williams was focused on producing pinball machines and video arcade games. Much later, in 2010-2012 WMS released its first video slot game for the online gambling market. And a couple of years later, in 2013, it was merged with Scientific Games, one of the biggest provider in the industry.
Even though WMS is a part of a big corporation now, it has been proceeding to grow its own library of games. The goal of the company is making engaging and innovative game content that could transform the player entertainment experience.
According to WMS Gaming’s LinkedIn page, more than 1,000 people work on the projects of the company at a time. So, it is a pretty large provider. And, actually, it is not a surprise, due to the fact that it has been on the market for about 80 years. In fact, its parent, Scientific Games Company, has more than 10,000 employees.
Initially, the company was based in Chicago, Illinois, and now its headquarters is located in Las Vegas, Nevada where the main office of Scientific Games is.
Regarding the provider’s portfolio of the games, it is represented by a quite varied selection of video slot games that come packed with both popular and unique features, and different math models. As I could find, its portfolio consists of more than 150 slots.
There are no card games in the company’s library. It can be explained by the fact that WMS Gaming had provided its products for land-based casinos till the 2010s. And after that, it has started from scratch. So, we can only expect that it will produce table games in the future.
Let’s consider all the aspects of the WMS provider’s business in more detail.
On this page, you can find the list of casinos that contain the games of the WMS Gaming software provider. Due to the fact, there are lots of online scam casinos that try to deceive their clients and steal their money, I made the decision very carefully on the bases of their conformity with the next criteria:
trustworthiness. A casino can’t have unsolved issues with players or partners. A client has to be convinced that he/she won’t be betrayed.
license validity. A license testifies that a casino has a controlling organization that keeps an eye on all its activities.
software validity. All the games that are represented in a casino have to be RNG-based. Usually, all settings, the math model and mechanics are checked by a special testing company.
account security. An account should be safe enough to keep money on it.
responsiveness. It can be ensured by a “live chat” option or through another way of communication. The main thing is an offered way has to be fast and convenient.
simple enough Know Your Customer procedure. This stage of registration verifies the client’s identity. So, if it is easy to pass, it allows a player to start the game faster.
the offering of good promotions. Popular promotions like Welcome bonus or Free Spins are always a delightful addition to the gameplay.
a wide selection of deposit/withdrawal methods. It is important to have an opportunity to deposit or withdraw through one of the most popular payment methods: bank card, E-wallet or cryptocurrency.
a reasonable deposit/withdrawal policy. The limits, terms and general conditions of deposit/withdrawal policy have to be acceptable for different types of players.
variety of games. If a casino has lots of different games in its library, every player will be able to find a favourite one.
user-friendliness of the official website. The more convenient website of a casino, the more satisfied a client.
You always can recheck my list of top casinos or make your own list with the help of the criteria that I’ve mentioned above.

Other conditions are correctly chosen games, bankroll management, and volatility. You can find many parameters of the games on this page and choose what suits you best.

In addition, along with the cash bonuses, he will receive a certain amount of Free Spins as another gift. These are so-called sign up bonuses, which are usually 100%, but you can find different offers.
In addition to the sign up bonus, players can also see other promotions. For example, you may notice that WMS casino offers a Free Spins Package. Just make a fixed deposit amount on a certain day and you'll get FS. Some bonuses need to be activated using bonus codes. You should receive a special email notification with such a bonus code and during the deposit, you can activate it.

WMS Slots RTP
Return to Player (RTP) coefficient can’t be ignored by players. It shows how much money you will get back in the long term if you play one particular game. And it is a rule that the higher RTP of a slot, the more satisfied a player. So, it is better to look for games with a higher RTP coefficient. Fortunately, WMS Gaming gives us such an opportunity.
So, video slots of WMS offer the highest RTP on the market which is around 99.00%. It is mindblowing generosity, I suppose that everyone agrees with this claiming.
Such an extremely lucrative RTP you will be able to find in the following slots: Nemo’s Voyage 95 (RTP of 99%), Moon Shadow (RTP of 99%), Monopoly Big Event (99%), Ooh Aah Dracula (99%) and Sheik Yer Money (98.2%). Remember, it is not a joke, playing these games, you can spin the reels and enjoy the 99% payback.
Of course, not all WMS games have superhigh RTP level. Most of them have RTP that ranges from 94% to 97%. As a result, the average RTP of the provider’s slots is around 96% which is quite appropriate to players.
In fact, Snow Leopard (97,75%) is also a slot that has a very high RTP coefficient.
Despite the fact that WMS is not an independent provider, it proceeds with making its own specific games which are full of innovative features and unique design’s decisions. It creates about 8-10 games per year.
For example, among the games that were released in 2020 by WMS Gaming you can see: Raging Rhino Rampage, Monopoly Electric Wins, Spartacus Megaways and so on.
In 2011, WMS Gaming created a jackpot pool. Such games as Jackpot Party Mega, Super Blowout, Surprise and Confetti Jackpots had a general 5-level progressive jackpot pool. And each of the jackpots could be won at random by the luckiest player who chose one of these games to play. It seems that these games don’t exist anymore, but we know that the provider is able to make games with a progressive jackpot.
To note, Life of Luxury Progressive and Tetris Super Jackpots slots are pretty new games of WMS Gaming that have a progressive jackpot.
It is a common knowledge that some players like engaging features and cutting-the-edge technologies, and some prefer classic games with a 5-reel configuration. So that it is great when a provider thinks about all of its clients and releases completely different games.
WMS is exactly such type of a software developer. It largely centred on the production of classic slots, whereas all of its latest games are very innovative and offer unique features that can surprise even a player with extensive experience.
The following features are represented in different slot games of WMS Gaming:
Free Spins. They are supposed to bring you extra winnings.
Bonus games. Such games are made to entertain players and add some fun to the gameplay.
Cascading feature. It can be found in some slots of this provider. For instance, Crystal Forest is a full cascading reels slot.
Megaways. Megaways is a reel modifier that is random. The number of symbols that appear on each reel during every spin is changed by a special engine, so it is different every time. As a result, the number of pay ways changes as well, and it can reach even thousands of ways to win per just one spin which is an amazing possibility for a player. Among WMS’s Megaways slots are Montezume Megaways ™, Raging Rhino Megaways ™.
Probably, you will be able to find some other unique features in WMS’s slots, and I recommend you to do it in an experimental way.
WMS offers a fairly big catalogue of the games, but just some of them can be considered the most popular among a large audience of clients. In fact, the most popular games of WMS Gaming provider are Star Trek, Monopoly, Willy Wonka, Chocolate factory and Wizard of Oz. These games were released over the years, but all of them can be called iconic.
Among modern online slots, the most rated games of WMS Gaming are Elvis the King Lives, Zeus III, Raging Rhino and others. These are well-implemented engaging video slots with fascinating features and fair math models.
How to Play WMS Slots
The studio's video slots have an intuitive interface. This is very convenient, especially for novice players. No special knowledge is needed to play the company's slots. Players only need to have a clear strategy related to their bankroll. Don't forget to keep track of the RTP and Volatility patterns.
Once you have read the paytable, move on to the slot settings. If you have chosen a slot machine with an adjustable number of lines, first select the number you want using the 'Lines' button. Then edit your stake with 'Bet/Line'. Keep in mind that the bet is per line, which means the total bet will be higher. You can keep track of it in the "Total Bet" window. The minimum bet per line in Studio slots is 0.01 coins, and the maximum is 300 coins.
The developer has provided one very convenient mode for users. If you have plans for a long playing session at a certain bet, you can use it. It is called Autoplay. This mode in which the drums rotate without your intervention of 10, 50,100 or 200 times. They can also automatically stop ahead of time if you set the appropriate settings for a particular win or loss.
Best 10 WMS Slots of All Time
The provider has been known for more than two decades. In that time, it has produced more than a hundred innovative slot machines. Every title in the catalog is trustworthy, but the most highly profitable ones are:
Snow Leopard - a slot model with a very high RTP of 97.75% and equally high winnings of 250,000 coins
Nemo's Voyage is a popular video slot thanks to its excellent 97% payout, but the maximum multiplier isn't good enough. It's only x75
Zeus 2 - 2019 video slot has an RTP of 96.77% and the highest multiplier of x150
Spartacus Super Colossal Reels plunges you into a historical event related to Sparta. This slot is of the highest standard, as evidenced by its excellent payout of 96.76% and maximum winnings of 250,000 coins
Cluedo Cash Mystery includes a 96.51% payout, x3,750 maximum multiplier and Medium volatility
Rainforest Dream can return 96.5% of bets and also give you a win of 200,000 coins
Neptune's Quest is a marine-themed slot machine with an unusual slot grid, a maximum multiplier of x1,250 and an RTP of 96.39%
Monopoly Electric Wins is another worthy model with a maximum multiplier of x16,667 bets and a yield of 96.39%
Frozen Inferno consists of an RTP of 96.36% and the highest multiplier of x1,250
Spartacus Megaways. The provider has included a 96.32% payout and a maximum multiplier of x12,500 in this model
The high quality of the studio's software has been recognised with numerous awards. Despite this, WMS games are rare because of their reluctance to distribute their products in the global iGaming market.
Security and fairness
Any good casino software provider has to be secure, and its products have to be fair and checked by a trustworthy third-party company. So, WMS Gaming can be estimated as an absolutely secure provider. Even when it wasn’t acquired by Scientific Games, it was under the control of the most reputable jurisdiction on the gambling market which is the UKGC.
Nowadays, it is a part of a huge corporation, so that we should know which licenses this corporation holds. Scientific Games has licenses of some reliable controlling bodies. They are the United Kingdom Gambling Commission, the Malta Gaming Authority and Romanian jurisdiction. So, now you are able to contact any of these organization to solve issues in case you have some.
Besides, always games of WMS were checked and approved by well-known on the market testing agencies. So, it is known that currently its games are tested by eCOGRA, one of the leading testing agencies. And players shouldn’t be worried about the fairness of gameplay’s outcomes.
Sound and Graphics
First online WMS Gaming slots were not extremely attractive, and the prevailing majority of them had a simple 5-reel design without additional features and complicated mechanics.
Today, the provider’s library of the games was increased. And dozens of more sophisticated slots are offered to the players at the moment. The graphics of the latest slots is high-quality and it is made very professionally, so it can be called attractive and engaging.
I’ve mentioned above the most popular games of WMS, all of them have a cool design. I mean the following games: Zeus III, Raging Rhino and Spartacus Super Colossal Reels.
Regarding the sound of the provider’s slot, it is well-made. Moreover, the latest slots have very profound and reach sound effects that affect the gameplay positively, in my opinion.
The games of WMS are HTML5-based and can be integrated into all applications running on iOS or Android. So, you always can find your favourite game in a mobile casino and enjoy the gameplay whenever you spend your free time.
Company history and perspectives
As I’ve said already, Williams Manufacturing Company started as a land-based casino provider in 1943. It supplied casinos with pinball machines and video games.
In 1996, it transferred its video games to its video game subsidiary, Midway Games, which became popular in the late 1990s.
In 1991, WMS created a new division, William Gaming that was responsible for making video lottery terminals. And some years later, in 1996 William Gaming released its first casino slot machine.
In 2000, WMS sold its pinball business. The next decade was full of different challenges for WMS company. It was sued by IGT and struggled with using diverse operating systems. Nevertheless, at that time, it created its very successful game like Monopoly-themes slots, The Wizard of Oz and Man in Black.
So, finally, in 2011, the company grew up rapidly and became one of the leading members of the market.
In October 2013, WMS Industries, which was the WMS parent, merged with Scientific Games (SG), the biggest corporation in the gambling industry.
Nowadays, WMS Gaming is a part of a big company that still is recognizable as an independent brand.
To sum up, WMS is an industry’s pioneer that has been on the market for about 80 years. Today, it is a part of the world-known Scientific Games company, and it represents proudly the corporation.
Even though the library of WMS’s online games is not very impressive, it has slots with diverse themes, features and mechanics. So, you can choose one of the provider’s Megaways slots, slots with a progressive jackpot, slots with super-high RTP or cascading-featured slots. Moreover, its games are safe and maximum fair. And they are really attractive which is an additional benefit.
Speaking about the provider’s shortcomings, there are no card (table) games in its catalogue, the number of games is limited, and its portfolio is growing quite slowly.
As you would expect, I’m ready to recommend this provider to you. Its video slot games meet all standards of high-quality products of the gambling market. You certainly should try them to make your own conclusion.
