Card betting in football lets you wager on how many yellow or red cards a referee shows in a match, giving bettors a different way to wager on a game. The best betting sites carry a host of card markets, including over/unders, team to get most cards, and specific players to be booked.
Card markets are influenced by referee tendencies, playing styles and match tension, meaning those learning how to bet on sport will be required to carry out a different kind of research when analysing card betting options.
