Real Money Casino Games Now Available Online for Americans

The first company to create real-money online casino games was Microgaming in 1994. Since these early days, the number of casino games providers has exploded. Currently, an average online casino in the US can have over 1000 slots games alone from more than 20 providers (just check out BetMGM’s video slots and progressive jackpot selection).

These online casino software providers go from niche online slots providers like ELK Studio to giant multi-billion dollar companies like Scientific Games, which provides games to everybody from lotto companies to Las Vegas casinos (under its Bally subsidiary).

Why casino game providers are needed

Casino game providers are a necessary part of online gambling. In the early days (pre-2000), online casinos made their games mostly by themselves. This was not a well working arrangement, as the fairness of the game depended on the casino. The quality of the games also left a lot to desire.

Now with the legalization of online gambling in the US, Americans can enjoy very modern slots from the likes of NetEnt, or play more old school slots IGT and Playtech bring to the table.

Top Casino Game Providers

The best casino game provider for American gamblers depends on preference. NetEnt offers great slot games (like Gonzos Quest), Evolution the best live dealer casino games, IGT’s slots you’ve probably already played at Vegas casinos, and so forth. However, it’s easy to pick our top-5 game providers as the most important ones.

1. IGT
IGT (International Game Technology) headquartered in Las Vegas, Nevada, is America’s top casino game provider. Their games consistently deliver top-performing entertainment and life-changing jackpots, totaling nearly $6 billion in payouts.

They offer innovative 4D casino games and is the largest supplier of slots in the world – their famous Monopoly, Cleopatra, Lucky Larry’s Lobstermania, and Da Vinci Diamonds are among American favorites. They’ve got a great sports betting platform too.

2. Netent
NetEnt, originally Net Entertainment, was the first one to create a Flash-casino in 2001. Before then, you’d always have to download and install a casino on your computer. But NetEnt figured it’s easier to play through your web browser and changed the casino business for good. This Swedish company has created two of the most globally played virtual slot machines ever, Starburst and Gonzos Quest.

3. Big Time Gaming
Big Time Gaming is the hottest company of 2021. They created Megaways slots with never-before-seen slot mechanisms. These are currently the hottest slots at most online casinos, especially since other slot providers have licensed the Megaways technology.

Currently, Megaways games are super easy to get free spins and other bonuses for, just check out the free spins list to see for yourself.

4. Evolution Gaming
Evolution Gaming changed the online casino world by making live dealer casino games a huge thing. These online games are played live at a real-life brick and mortar casino, and you can get in on the action by betting on your phone or computer. These live casino games are hugely popular, and Evolution Gaming is the biggest company behind them with hit games like Monopoly Live, and 2 Hand Casino Hold’em.

As you can see from the list, most of the providers are from the nineties or the last ten years. There’s a couple of older companies, like Scientific Games (owner of Bally) and Novomatic, that predate the internet.

A notable omission in this list is Microgaming, the father of all software providers. Thing is, Americans can’t currently play Microgaming games due to licensing issues. But we’re sure to keep an eye on Microgaming getting a permission to offer their games to Americans sometime in the near future.

US Casino Bonuses for Game Providers

You’ll get a casino bonus for any of the top game providers. Online casinos give you welcome bonus offers for any slots provider you happen to like, as you can see from the table above. Even the biggest provider in the world, NetEnt, can be enjoyed with a good deposit bonus.

We can even get some free money, as online casinos like Virgin Casino (NJ) and Tropicana Online (NJ) give out 10 bucks when you insert a promo code BF10VIRGIN or BF10TROP when you sign up. Both of the casinos feature games from the likes of IGT, WMS and Bally.


With hits like Reel Rush and The Wolf’s Bane, NetEnt is the most popular game provider right now.

Jackpot Providers

If there’s one thing casino game providers love to compete on its jackpots, whoever has the biggest jackpot has bragging rights. Online progressive jackpots have been around since the late 90s, and by now, all the major casino vendors have one.

The biggest jackpots and providers:

  1. Mega Fortune / NetEnt
  2. Beach Life / Playtech
  3. Millionaire Genie / Random Logic
  4. Millionaires Club / Cryptologic
  5. Wheel of Fortune / IGT

Mobile Casino Game Providers

The first major game provider to fully go mobile was Netent in the early 2000s. While Microgaming had created a few mobile games as early as in the 1990s, it and other companies still relied on downloadable gaming platforms.

NetEnt changed mobile gaming in around 2002 by creating instant play games that load in your web browser. This ensured that you can play its on a computer, Android phone, or iPhone. Netent was also the first to understand that touch screen devices are actually better for casino games than computers, and it created its patented Netent Touch technology that makes it easy to play slots and table games on phones and tablets.

Once NetEnt had figured out the mobile technology, rest of the casino industry followed. Nowadays all casino software development aims for a perfect mobile gaming experience and each provider has its own mobile gaming platform. Many of the companies, like ELK Gaming, have actually been founded by former NetEnt employees, so mobile gaming is very familiar to them.

Safety & Security

Online casinos are licensed and regulated by the authorities of their home countries. The same logic applies to casino games. Selling (licensing) a real money gambling software requires a license and to acquire one you need to show that your software runs fair. For example, a common requirement by licensing authorities is that the game plays the same in play-money and real-money modes.

The biggest and most trusted authority to license gaming providers is the UK Gambling Commission. UK Gambling Commission’s Remote gambling software license ensures that a software company adheres to the commission’s standards, ensuring the software, be it a slot game, roulette or other gambling, is fair and safe to play.

The authorities on our side of the pond trust UKGC as well. US authorities like New Jersey Division of Gaming Enforcement and Pennsylvania Gaming Control work together with UK Gambling Commission to ensure the fairness of the games. So yes, you’re playing fair games online.

Casino Software Platforms for American Gamblers

Besides just casino game providers, there are also casino platforms. These platforms combine games from many different providers, as well as different kinds of games like casino, betting and poker. Well-known casino platforms include:

  • Relax Gaming
  • Nyx Gaming
  • White Hat Gaming
  • Softswiss
  • Every Matrix
  • SkillOnNet
  • Inoru

Being aware of casino platforms and what they have to offer is useful since casinos running on the same platform will likely have the same games and a very similar experience overall. For example, 888 Casino runs on its own platform, while Virgin Casino operates on Gamesys.

This is why, at BonusFinder we’re invested in helping American players find which casino game provider suits them, and which casinos offer the best bonuses.
