Flip a coin
Introduction
In soccer, the referee usually decides which team will kick off first by tossing a coin. Before the match begins, the referee calls the captains of the two teams and then makes a coin toss, where the team that wins the toss gets to choose whether they want to kick off first or choose the field. If they choose to tee off first, then the opposing team chooses the field; and vice versa. This method of tossing a coin is fair and ensures that the game is fair.
