I can cover this one.
So in general there are 3 parties involved.
Casino - The ones fronting the whole thing that have the end users who sign up, put in money etc
Platform Provider - The ones who provide the accounting and reporting integration to the Casino, and the back end logic for the games. So when you place a bet with the Casino, the Casino sends a message to the Platform saying 'Player X just placed this bet on Game Y, please generate a result and tell me how much I need to pay them back'.
Game Provider - The ones who produce the games, the graphics, the front end, the mathamatical model etc. Sometimes they also produce the back end themselves and integrate it to the Platform, sometimes they will even build it on the Platform directly (although I believe that is rarer now days).
In some instances the Game Provider and the Platform Provider are the same company.
In terms of the contractual relationships, they go like this
View attachment 155468
Where each line is a many to many relationship.
A Casino will have contracts with 1 or many Game Providers and 1 or many Platform Providers.
A Platform Provider will have contracts with 1 or many Casino's and 1 or many Game Providers.
A Game Provider will have contracts with 1 or many Casino's and 1 or many Platform Providers.
Most deals work on a profit share per month, so whatever profit the game makes in a month is shared between the three parties. If the game makes no profit, noone gets any money. Sometimes losses are rolled over to the next month and offset against profits. It depends on the contract.
In general, the numbers are around the following:
Casino - Takes about 70-80%
Platform Provider - Takes about 10-15%
Game Provider - Takes about 5-10%
The better content the Game Provider has, the better the deal they can strike. The more high quality content a Platform has, the better deal they can strike.
Then you have things like exclusives, where the Casino will offer a higher percentage, or a one time fee, for a limited exclusivity period with a game.
This is the most common setup
