Research Methodology
All markets in this analysis are presented using Gross Gaming Revenue (GGR) or Gross Gambling Yield (GGY).
Definition
GGR / GGY = Total player stakes minus winnings paid to players.
Different regulators may use either GGR or GGY terminology, but both represent the same core measure of operator revenue generated from gambling activity.
