How It Works
Impact Sub is a unique promotion where if a player you bet on is substituted during a football match, your bet automatically transfers to the substitute who replaces them at the original price. This applies to pre-match and in-play singles, multiples, and Bet Builders across selected player markets including First Goalscorer, Player to Score, Player to Assist, Player Shots on Target, and more. If the market requires multiple occurrences (e.g., 'to score 2 or more'), any action by the original player carries over and combines with the substitute's performance.
