@ GG: Russia, China, Canada, Brazil. Then the United Kingdom, Germany, Austria, Ukraine, Thailand, Belarus, etc. Eastern European and Asian countries.
@ WPN: United States, Russia, Canada, Brazil.
Then the United Kingdom, Austria, Ukraine, Belarus, Poland, Hungary, Argentina, etc.
In practice, the four (five) main ones are... Russia, USA, Canada, Brazil, China.
The UK and Austria show significant growth, especially in the WPN rooms where, strangely, players from Asian countries are scarce, some from Thailand, some from China and Hong Kong, but they are very few compared to GG Poker, players from Vietnam, the Philippines, Laos, Cambodia, etc are almost completely absent.
