What is Juice or Vigorish or Vig?
The term “Juice” is actually a slang term for Vigorish or “Vig”. In sports gambling is the amount of money or commission a sports book receives for taking your bet.
Most of the time, the sports books takes a 10% cut for the amount of each wager, but the juice amount can vary from book to book and from sport to sport. For instance, most online sports book use 20% vig or juice for Baseball commission.
The sports book only collects the juice if the bet is lost. Conversely, juice is not paid to players on winning bets.
