Select the league(s) you want to play with, the decades of seasons
to include, and the statistic you want to use.
At each turn, a random season and a team from the selected leagues
will be chosen. Your goal is to guess which player from that team
had the best value for the selected statistic.
After 10 turns, you will receive a percentage score based on your
accuracy compared to the maximum possible score.
*BPS = Best Possible Score
