I know Pokerstars has huge numbers of players. I know that Spin and Gos have a huge slice of the action at Pokerstars.
I'm still somewhat surprised that 44,487 people managed to qualify for the Spin & Go freeroll yesterday. The criteria? Having opted in (which by itself would remove a lot of players), within a 2 hour slot, win 5 Spin and Go's.
I wonder how many million Spin and Go's are played every day.......
