Football betting sites utilise a system known as 'booking points' to quantify the number of yellow and red cards issued during a match. This terminology helps punters understand disciplinary events within a game.
Under this system, a yellow card is allocated 10 points, and a red card is allocated 25 points. These points are awarded to individual players for the cards they receive, with a player potentially accumulating up to 35 points in one match if they receive both a yellow and a subsequent red card.
Punters can bet on various booking points markets, including the total number of booking points in a game, which team will receive the most points, or whether the total will be over or under a specified number. Factors such as the referee's history, the teams involved, and the match's intensity can influence the number of booking points.
