I agree that bingo needs to be investigated, I have seen the top ten people win game after game after game. I have been in the room for twelve hours at a time and it is mostly the same people winning. They talk about knowing which seats to sit in. How would they know that?
Bingo is a game of chance like any other. The seat you sit in does not affect your chance of winning. But just like anything involving luck, people might have their "lucky seat" they prefer to sit in, just like they might have a lucky hat or a number they prefer to bet on in roulette.
