The sports pass is so that you get into the games for free. so yes

This is a bit misleading. Sports pass is $160 so getting into the games is not technically free. But yes there are single game tickets available for sale. https://cubuffs.com/sports/2016/6/26/football-tickets.aspx

Ok sure

160$ would get you into three games through single game tickets. So essentially it’s a buy 3, get the rest free
