I played the game on a recent cruise. I played the baseball version, but I suspect that the football version is similar. We were in port, so I played against the CM.
You start out with a budget of $25 million. You are given a sheet with various players at different positions and salaries. Each player picks 4 pitchers, 3 outfielders, 1 first baseman, 1 second baseman, 1 third baseman, 1 shortstop, and 1 catcher. A player gets two picks in each round, i.e., Team 1 picks 2 players, Team 2 picks 2 players, etc. You are then scored in 8 categories: HRs, RBIs, SBs, Average, Wins, ERA, Saves, and Ks. The object is to get one more stat in each category. For example, if there are two teams competing, then you want only one more SB than the other team because you will get more points in that category than the other team.
