How Sportsbooks Create Edges

A sportsbook is a type of betting platform that offers bettors an opportunity to place wagers on a wide range of sporting events and outcomes. Often, these platforms offer multiple types of bets, including single and multi-team bets, and multiples such as doubles, trebles, and accumulators. Some also offer a live casino, full-service racebook, and a plethora of slot machines, table games, video poker, and bingo.
