The Amaya-owned poker operator registered another milestone last Sunday. PokerStars, with players from all the globe, staged the record of 1,275 tournaments.
The initiative coincided with the PokerStars Spring Championship of Poker Main Event.
Severin Rasset, director of poker innovations and operations at PokerStars, said: "This is a really special day for us and our players, which will go down in online poker history as a record-breaking moment.
"The huge prize pools on offer further cement our position as the biggest and the best and on Sunday when players compete for $28 million we will be delivering millions of winning moments too, Rasset added.
