Providers

The transfer from physical slot machines to online slots would not have been possible without the software developers that managed to bottle up the land-casino atmosphere and transfer it to the internet medium. These providers’ flourishing took place in the late ‘90s and most of them offer a wide selection of games, from free online slots to bingo, baccarat, blackjack, poker, craps and many others. Each company is known for something, they have a specific feature that will make a player recognize the brand instantly. It can be the specific atmosphere, the stunning graphics or the originality of their free online slot machines.

On zzzslots you will find many free slots, developed by different providers. Some of them are big brands, the giants of gambling industry with names that need no further introduction, others are small companies, newly founded, that try to keep up by offering unique experiences.

Microgaming is the best example of a software developer that hit it big. It was, in fact, the world’s first real online casino, founded back in 1994, and with the passing of the years all this provider did was expand and improve. The news that the biggest win ever was registered by a gambler playing a Microgaming developed online slot, spread the word about the company. Jonathan Heywood was the lucky winner of a fabulous sum of approximately 18 million euros by playing Mega Moolah, an already classic Microgaming slot machine.

Besides Microgaming’s specialists are deeply involved in the creation and developing process, they also use Flash and HTML5 to make sure their free online slots are compatible with Windows, Android, and iOS. What is more, they offer a great variety of bonuses. They won multiple awards for their perfectly designed games. You can try them out and check out their classics like Loaded, Thunderstruck, and Immortal Romance.

The Swedish company NetEnt is another giant from the gambling industry. They were the first to use JavaScript for their platform, but then they switched to HTML5 and Flash. They are making sure players have a fair and correct game by being checked for randomness by two different companies! They take their job seriously and they are very good at it! The payouts are great, too, and you have the benefit of getting a lot of bonuses! The massive progressive jackpots of their online slots catch the attention of any experienced player as does the fact that NetEnt was the best ”Slots Provider/Supplier of the Year” in 2015!

Another big name is Bally Technologies, a provider dating back in 1968. It has changed its name a few times and it is known for providing popular slot machines for both the online playing as well as for the land-based casinos. They’re the best when it comes to the gaming software, graphics and the bonuses you get. Of course, their free online slots are fit to be played on any device nowadays, from a laptop to a tablet and smartphone as long as there’s an internet connection available.

BetSoft is specialized in 3D slots. They were the first to develop the technology necessary for this kind of online slot machines and they created an incredible cinematic gaming universe. With SLOTS3 and other 150 games, BetSoft excels when talking about graphics and sounds. They obtained a license from a prestigious authority in this industry, so this provider’s authority cannot be questioned.

Playtech is another big company, one that is concerned with quality and results. They have licenses from prestigious authorities and thus have the reputation for being fair and secure. Their preoccupation for pleasing their players is shown by the fact that they have signed exclusive contracts with comic books and movie franchises to develop online slots featuring your favorite heroes and superheroes!

Their top-quality online slot machines and their presence in the gambling business for many years have made Realtime Gaming one of the top developing companies out there. They give casino managers the chance to change some settings for the games, so their slot machines may look different from casino to casino. Another great feature is that players can actually play multiple games at once as they can make the games’ windows smaller! Their most popular free slot machines include adventures during which you search for gold and diamonds in Aztec’s Treasure, Diamond Mine and Incan Goddess.

The list of slot machine providers is a long one as you will see below. Here are the big names from the industry, but that doesn’t mean that the smaller companies don’t deserve a chance! They may as well impress you with a certain feature they focus on. Our advice? Check them all out! You have nothing to lose!
