The Retro Bowl is a football game in the United States that takes you back to the good old days. If you like football, I'm sure this is the best mobile game you've ever played.
The main rules for the Retro Bowl are a lot like the rules for American Rugby. There are two teams, each with eleven players, going up against each other. The goal of the tournament is to get more points than the other players in the time allotted.
Have fun and good luck!
