In IPL (Indian Premier League), the impact rule is a method of determining player rankings based on their performances in a match. The rule is used by the official IPL website and app to rate players after each game.

The impact rule takes into account various factors, such as the number of runs scored, wickets taken, catches, and run-outs affected, as well as the context of the match, such as the stage of the tournament, the opposition, and the venue. The impact of each performance is then calculated using a proprietary algorithm, which assigns a numerical value to each contribution based on its importance to the outcome of the game.

The impact of each player’s performance is then aggregated to determine the player’s overall impact rating for the match. The ratings are updated after each game and are used to rank players on the official IPL website and app.

The impact rule is intended to provide a more comprehensive and objective measure of a player’s performance in a match, beyond just the traditional statistics of runs and wickets. It also allows fans to track the performances of their favorite players and compare them to others in the league.


The Impact Rule in IPL (Indian Premier League) is a statistical measure used to evaluate a player’s performance in the tournament. It takes into account various factors like runs scored, wickets taken, catches, run-outs, and stumpings, and assigns a numerical value to each of them based on their importance in the game.

The Impact Rule was introduced by the IPL in 2018 and is used to determine the most valuable player (MVP) of the tournament. The rule takes into account the player’s impact on the game, rather than just the number of runs or wickets they have scored or taken.

The Impact Rule is calculated using a complex algorithm that considers various factors like the match context, the quality of the opposition, the venue, the stage of the tournament, and the player’s overall contribution to the team’s performance. The algorithm assigns a numerical value to each of these factors and combines them to arrive at a final Impact score for each player.

The player with the highest Impact score at the end of the tournament is declared the MVP. The Impact Rule has been praised for its ability to recognize the contributions of players who may not have the most runs or wickets, but have made crucial contributions to their team’s success.


In the Indian Premier League (IPL), the substitute rule allows teams to replace a player who is unable to take the field due to injury or illness. The substitute must be a player who is not already part of the playing XI for the match.

If a player is injured or falls ill during the course of the match, the team can apply to the match referee for permission to bring in a substitute. The substitute must be approved by the match referee, and can only take the field in place of the injured or ill player. Once the substitute is on the field, they assume all the rights and responsibilities of a regular player, including the ability to bat, bowl, and field.

It is worth noting that the substitute rule is not always applicable in all forms of cricket, and is a specific rule unique to the IPL. In other forms of cricket, such as Test matches and One Day Internationals, there are different rules and regulations governing player substitutions.
