There will probably be like 10 games each week that you pick who you think will win. It could have confidence points that you have to pick as well, but I don't know that for sure. If it does have the confidence points also, then you want the higher amount of confidence points set to the game you think is a for sure win.
So an example, say there's 10 games. So if it has confidence points, then it'll range from 10 points to 1 point. Which ever game you have the most confidence in, you put the 10 next to it. Whatever game you have the least amount of confidence in, you'd put the 1 next to it. However, I don't know if this one will have confidence points or not, so yea.
It could just be a straight up pick'em. Where at the end of the season, whoever has the most correct picks wins. The confidence points is to make it a little more challenging (and fun) and to make it so there's a very, very slim chance of a tie at the end of the season.
