Hi, 
you can log in to multiple rooms at the same time.

Hi 

It's great that you can register as a player in multiple rooms! But many players use it to steal points from other players. That's what happened in my game: I played in room 1 against a player who also registered in room 5 and lost 4 games against a friend, going from level 500 points to 400 in order to steal as many points as possible from my 1100 points in the event of a draw or loss. That's why I reported the player to the moderators and he only got a 2-day penalty. I won both games and only got 1 point, but there are players who just wait for something like that in the room. That's why I suggest you rethink it and write in the rules that you can't play 2 games in the same period of time.
