GGR

GGR is calculated on gameplay alone. Bonuses handed out, payment processing fees, affiliate commission and platform costs all sit outside it, which is what makes it gross rather than net.

Its usefulness comes from having one widely accepted definition. Two operators quoting GGR are measuring the same thing, and a figure can be checked against a platform's own reporting without agreeing terms first.

That is also why platform revenue shares are often quoted on it. A percentage of GGR is unambiguous, where a percentage of a net figure depends entirely on what that contract chooses to deduct.
