Poker. In pai gow poker, a 5% commission charged on all winning bets is referred to as vigorish. Unlike baccarat, the commission is paid after each winning bet, either by the player handing in the amount from his stack of chips, or by having the vig deducted from the winnings.
The answer is simple. You pay for the bookmaker's services through what is known as juice, the cut, or the vig – short for vigorish, a term that comes from a Russian word meaning “winnings.” The industry standard for vig is 10 percent, which means that for every $1.10 you wager, you can take $1 in winnings.
Vig, or vigorish, is the cut or amount charged by a sportsbook for taking a bet, also known as juice in slang terms. The sportsbook only collects the vig if the bettor loses the wager.

Vig is short for vigorish, and the two terms are interchangeable. The amount of the vig is part of the odds for all bets. Essentially, the vig is the equivalent of a fee or commission that online sportsbooks charge. It helps to make sure that the book makes money regardless of how a game goes.
