There is no way to game the system. The illusion that you can somehow understand how the game works and what will happen next keeps a lot of players coming back to end up losing more money. Studying old games to show a pattern does not work, it is simply a game of luck.
Did you mean fantasy football? where game is played by bots, or e-football where there are two players/teams playing against each other.
I think OP is referring to Fantasy football.
