When you factor in it is the NFL it makes it more like 65,000,000,000,000,000,000,000 to 1

Gotta love how the GN does it.. they have a 20-team parlay card.. bet $5 to win $1 million. Just call 20 bets correctly. Couple things with that... a $5 bet should pay about $5.3 million instead of $1 million at 50/50 odds on each... but get this... ties lose.

With 20 bets a week, there's a pretty strong chance that one of those games will tie, especilly when they put key numbers on the card (3 for example). In other words, your 20% return (80% expected loss) is closer to 5% return... or in other words, you're giving up 95% of your money wagered.

I like the GN, but it'd be nice if they made it 19 or even 18 (instead of 20) to give a chance to the bet, or at least put half-point lines up on all bets. They'd still have a huge edge.

to figure out the true odds of any parlay - just do this


2 - to the power of the number of games (for each game can have 2 results - fave or dog covers)

so on a 2-team it would be "2-squared" or 4-1

on a 6 teamer it would be "2 to the power of 6" or 64-1

a 16-teamer would be "2 to the power of 16"

which is also "16 to the power of 4"

or "256-squared" - which as fish points out is 65,536

but as woody also points out - you need to subtract "1" from it (i believe) so the true odds would be

65,535:1

either way - one hell of a longshot

A friend of mine hit one years ago, it was on a last weekend of the NFL season and he was zoned into how each team would approach the games and all. Most of the season it is just calculated guessing, this one week every year is one where if you zone yourself right you can pick at a pretty high percentage.

This buddy of mine and I agree, BTW, that Houston looks like a monster play this week. If Cleveland puts up any kind of fight we would be stunned because they sure haven't the last few weeks and no reason to expect it here on the road to close out a miserable year.

Would you guys consider the implied odds to be a bit better if you took all underdogs with points?

Not for football, but for basketball on a Saturday where you have 75 games to choose from. All underdogs certainly gives you a little better shot. Maybe like 40,000 to 1 or so

0.50^16 = 0.0000015259 and then ^-1 = 65536

10 teamer = 0.50^10 and then ^-1 = 1024
etc
 

There's always next year, like in 75, 90-93, 99 &

1 in 2^X-1 with X being the number of games (assuming there is a 50/50 chance on each .. if would vary greatly if you threw some chalk ML in there)
