Hi PLaw,
Well, let me try to explain. When they draw names before the game and fill in the squares, if you are on the four corner squares, for instance, you already won $100. Also, as in my case, I have number "5" which, when reading the list, both horiztonally for one team, and diagonally for the other they meet at my name at # "5". (Meaning, the score for then end of each quarter must be for example 15/25). Make sense????
Also, in this same pool, if your number is touching any of the winning people's number at the end of each quarter, you win $160; if your numbers are reverse from the final quarter scores you win another 160 or so.
Anyway, I like that there are many different ways to win. Only the four corners and the "double" numbers win "before" the game.
Remember it's not the sport of football I like, it's the sport of gambling. :p However, my son-in-law says that five isn't a likely number.

Hope he's wrong.
