OK, before you get too confused by everyone answering wrong, realize there are 2 types of bets:
1.Spread - usually even money if you win or something like 95% return (meaning if you put down $50 you will win $48-50 depending on how much the house takes). The deal with this is that they come up with a point spread, say 7 1/2 points that seems fair for both sides. If you take the team favored by 7 1/2 points and they win by 8 or more you get your original $50 back plus the $48-$50 in winnings. If that teams loses or wins by 7 or less points, you lose your money. If you put $50 on the under dog they only have to lose by 7 points or less and you'll get back your $50 plus your $48-$50. Simple enough right?
2.Odds - this is tougher, but the basic idea behind this is that you pick a winner but depending of the game it will pay back certain odds. For example if the Bucs are playing Detroit you pretty much know the Bucs will win but you will not get a good return. If the number by the Bucs is say -6.50 that means you need to put down $6.50 to win $1 (plus your original $6 of course). If the number by the Lions is +5.50 that means if you put down $1 and the Lions win you'll get your $1 back plus you'll win $5.50. So you can see you can bet on the Bucs everytime and put down like $65 but you'll only walk away with $10 if they win....is the risk worth the reward? And if you put down $10 on the Lions you could walk away with $55 if they win...again risk/reward.
(I can't remember my - or + actually but you'll know by who is the favorite for the game)
