You need to hit all games, say 10/10, UNLESS nobody gets 10/10 who bought a ticket, so it then pays out everyone who hit 9/10.

That link, was from week 15, 1 winner for the NFL Pro Pools. Guy won $874,000. That was the week Green Bay lost and Indy won (or whoever hadn't had a win yet).
I've actually been tracking NHL Pro Pools, in excel, I've been "making up pretend tickets" since November. I'd be up around $6,000 if I actually played them.
When there is 13 games on, the average pot has been $38,000. You can box out 11 games for $10,240. That mean if you pick 2 games correct, you would've profited ~$28,000 when there is 13 games on.
If anyone would like to see my spreadsheet, let me know
