How do you tie in football and what are the rules for determining a tied game?

In football, a tie occurs when both teams have the same score at the end of the game. The rules for determining a tied game vary depending on the level of play. In professional football, if a regular season game ends in a tie, there is usually an overtime period to determine a winner. If the game is still tied after overtime, it may end in a tie or go into multiple overtime periods until a winner is determined. In some cases, a tie game can also occur in college or high school football, but the rules for resolving ties may differ.
