I read BH tips on the game and still have a question. Ranking is based on bingos. When you play in a 6 card room, does that count as 6 Bingos or just one? I am playing in a room, alone, letting all the numbers get called before I call bingo. I want to rank up as fast as possible and would like any suggestions. I do know about jumping to a new room after the bingo is called. Thanks.
