Extra Time refers to a period of additional time played following a draw after the regular period of play is completed. This is most common for Soccer competitions where a winner is required, and scores are level after the 90 minutes scheduled time is completed.
Extra Time does not apply in regular bets that are placed for events unless specifically stated in the betting market, and must not be confused with added on or injury time that is added onto the 90 minutes playing time to replace time lost during the regular gameplay.
