Total noob when it comes to betting on football, don't know shit about "squares" don't know shit about betting on the actual games when it comes to "over and under"

someone please enlighten me!

“Squares” is a 10X10 grid with the numbers 0-9 labeled for each block on top and 0-9 for each block on the left hand side. For example: Say the Cowboys represent the top 0-9 numbers on the grid and the Packers represent the left side numbers (0-9) if you buy the block 5 – Cowboys 2 – Packers which represents the last digit of the final score (or half time depending on how you want to do it) and the final score is Cowboys 15 Packers 12 then you win.

“Over/Under” betting depends on what the odds makers set the final score of both teams at.

Example: Odds makers set the final score for a game between Dallas and Green Bay at:

Cowboys 15
Packers 12

Combining the two scores = 27. To wager an over/under bet you would be betting that that final two scores combined would be either over 27 or under 27.
