Yea I understand haha I got it. I have no idea how betting works other than the spread. I don't know what parlay means or what "-105" means for a game. I just put $20 each on Seattle and Detroit. See how that goes
Parlay is french for 'a 100% tax on people with too much optimism'.
Basically you tie multiple bets together into one big bet with a bigger payout. So a 3 game parlay means you have to get all of your bets right for 3 games and if you do you win substantially more than you would if you placed 3 individual bets. But if you're wrong about any single game you lose your entire bet.
-105 is basically what you need to bet to win $100.
So in that example the Patriots are -21 -110 if you bet the point spread. Meaning you have to bet $110 to win $100 and the Patriots need to win by 22 for you to make money. If they win by 21 it's a push and you get your money back, often minus the juice (the fee the book charges for their service. My book in Reno was the Atlantis and they gave you all your money back on a push and I love and miss them.) If they win by 20 or less or lose kiss your $ goodbye.
The second is the bet on the total score. 43 O/U means over/under 43 points. Notice the payout is the same, a $110 bet on scoring more or less points than 43 nets you $100.
The last is the money line which is just a straight up bet on who will win. You have to bet $3500 on the Pats to win $100. If you bet $100 on the Jets you win $1300 if they win.
All I do is bet on the Pats and the occasional teaser (teasers are like a parlay but you 'tease' the line however you want for much less of a payoff. So a 5 team 6 point teaser means you get to move the line for 5 different bets by 6 points. So instead of winning by 22 the Pats would need to win by 16 and you'd do that with 4 other games.
Buying points is another thing you can do where you reduce your payout but move the line. For instance if the line is -3 1/2 I often 'buy' half a point to move it to -3 because it sucks when it's OT and your team is driving and they win by a FG and the line was -3 1/2.
And if fightingirish disagrees with any of the above listen to him, not me.
