A-Z of Online Casino Software in the US: 2023 Guide

Updated: 13 February 2023
Online Casino Software Providers

The online casino software providers are the backbone of the iGaming industry. They’re responsible for all the spectacular games you play. All the game mechanics and payouts are ultimately handled by these developers. Many of them also develop full-fledged casino software.

The thing is, the providers often remain in the shadows. They don’t make much noise other than acquiring new creator studios and/or releasing new games. The goal of our guide today is to give you the ammunition you need to choose the right brands for your game needs.

What is Casino Software?

The iGaming industry has 2 major distinctions. The online casinos and the online sportsbooks. In the sportsbooks, the primary software is designed to handle all the operations.

But when it comes to online casinos, the website interface is just the surface of the technicalities. All of the games you see displayed are actually supplied by the software providers. The operator of the casino has license agreements with the providers that allow them to offer the games to players directly.

  • The Software Provider – Online Casino Symbiosis

The nature of the iGaming industry doesn’t allow casino operators to go solo. They are dependent on the software providers for a game library. The providers, on the other hand, need the operators to showcase and deliver their creations to the end-users.

Of course, there are exceptions to this where a software provider develops its own casino interface and vice versa. But it’s not the norm.

  • The Casinos Offering Games from A Variety of Providers

The biggest advantage of the operators and the software providers being different is the variety. You can play all kinds of games at a casino online, offered by a multitude of providers. On the contrary, most providers specialize in 1 or 2 types of games. So, if they open their own casinos, the game library is often very limited.

  • The Providers are in Control of the Mechanics

The RTP of the game, the RNG, the payouts, and all other technical aspects are controlled by the software providers. Some providers offer a variable RTP range to allow casino operators to comply with regulations.
