When looking for the best games, it is important to know what separates the best game providers from the rest. Knowing which providers make the best games will make it easier for you to find the online casino that best suits your needs. 

This page will help you know who the top providers are for games in the US, why they stand out, and learn some of the games offered by each. 

What are Online Casino Game Providers

Software providers are the companies that create the amazing games we play. They are not only responsible for the graphics and gameplay, but their goal is to continue offering new games with various themes to keep you coming back for more. 

In addition, these providers are also responsible for the games’ RNG software, which is used to ensure that all outcomes of each game are random and fair for all players. 

Software providers and casino operators are reliant upon one another, and must work together for their mutual benefit. They both want to create and host the best games for players to play.

There is a difference between Platform providers and Software developers.
Software Developers are the game makers, and Platform Providers make the player interface (online casino websites).

Game Providers - Legal and Safety requirements

It is not just the online casinos who must be officially licensed, but also the software providers. Without a license, providers cannot sell or distribute their games to online casinos. 

In addition the look and play of each game, providers must also think about security of any personal data and safe play. Online casinos host lots of personal information and many people use their debit/credit cards for deposits and withdrawals. Knowing that a provider has taken the necessary steps to obtain a license means that you can also be rest assured that all of your information is safe when using their software. 

Fairness of games

All games at online casinos (with the only exception being live dealer games) use what is known as RNG software, or Random Number Generator software. This software works to make sure that all game outcomes are completely randomized and fair to all those that play. 

All online casinos are monitored and regulated by their respective state’s gaming board/commission. These government agencies randomly inspect games at online casinos to make sure that they are meeting all laws and regulations accordingly. 

For more information on your state’s gaming regulations, you can check out your state agency’s website:

In addition to state regulators, there are also international organizations who regularly test new games as they are produced to make sure they are safe and not rigged. The most commonly used independent labs/companies for this include: 

  • BMM Testlabs
  • eCOGRA
  • iTech Labs
  • Gaming Associates
  • Gaming Laboratories International
  • NMi
  • SQS
  • Technical Systems Testing

Game providers are also responsible for all their games’ RTP, or Return to Player. RTP is a term casinos use to describe the theoretical percentage of all wagered money a game will pay back to players over time. 

The formula for calculating a game’s RTP is:

        RTP = 100% - the House edge

So for example, the House edge in Roulette is 5.26%. So the RTP for Roulette = 100% - 5.26%; making the RTP for Roulette 94.74%. 

When selecting games, you want to look for games that have the higher RTP as these games will provide the greater return on overall wagers.
