it runs 365 days a year and does include nfl games and nfl prop bets (yards by QB, RB, player vs player, points in a quarter/half etc.)
I have done this for a few months, its fun. I suck at it. The best day I have seen so far is Christmas day where they do all the NBA games. I dont really follow the NBA that much, but I got them all right besides the 2nd game. So I had a nice little streak, but then of course blew it the next day by picking some soccer crap which I have no idea about.
Because every time I've heard about it has been after/before the NFL season, never during. I also figured NFL games would be much easier to pick, but they probably only choose a select few and/or incorporate the spreads. I'm riding a W5 right now, but my current pic is Zeller/Oladipo, and they're both on the bench. Looks like a combo breaker.
it runs all year, they'll put all kinds of NFL games up, they're actually the hardest to pick IMO. But in reality everything on there is a coin flip, winning the money is like picking a coin flip correctly 26 straight times, very slim odds.
For whatever reason, SFTC doesn't keep my totals. It claims I'm 0-2... no matter how many times I play. And that my longest winstreak is 0 when it used to be 13. Dunno what's up with that. If I stop playing for more than a week or so (often) it forgets I ever existed. What a jerk.
