However, I know not all of you are like me, the Party Girl, so here are some other games and activities you can try:
the football pool
This is standard. Add prop bets for how long the game will last, who will be the MVP, who wins the coin flip, who scores first touchdown, who has first turnover, score at the end of each quarter, etc. and give out gag gifts (see below) instead of money for these extra-added guesstimates.
Write out all of the possible wins or bets on sheets of paper for all of your guests.
Hand them out at game time with some pens.
At the end of each quarter tally up who won and give out gifts.
