Everyone plays it differently. In my family we make rules at the start of the game "We're playing full card!" means we're filling up the entire card, or "Across only!" means we're only accepting 4 in a row straight across and then we also play "corners" which is filling in the corners. That's just how we do it. We yell "Bingo!" when we win, or else it doesn't count haha. We usually start with "across" because it's the quickest, and easiest way to win. Then we start with the "corners" and "full card" to get the games to drag on longer, and of course increase the amount of money that's being bet haha.

I've never heard of the rhyming thing before. o_O
