Basically, in Bingo, you get a card, you have a certain amount of dedicated numbers, if all of your numbers are called out first, you win! Usually you'd shout BINGO, and you'd win whatever prize, be it cash, or Idk, a hamper of goodies, or something like that.
Easy as that to explain, no picture aids (No hands, y'all).
Edit: Before anyone says it. No I did not read through previous posts, (just a couple) so maybe it was already explained like that but I'm a lazy bastard, as you all know.
