Vigorish Explained: Casino House Edge & Commission
Vigorish, often called vig or juice, is the commission or fee charged by the house in gambling games, representing the casino’s built-in mathematical advantage over players. This fee ensures the casino’s long-term profitability regardless of individual game outcomes. Players encounter vigorish in various forms across table games, sports betting, and poker rooms. Understanding vigorish helps players assess game fairness and expected returns. In Australia, licensed online casinos disclose vigorish through metrics like house edge and return to player percentages, as required by regulators to promote transparency.

How Vigorish Functions in Casino Games
Vigorish appears as a commission deducted from winning bets or embedded in payout odds. In blackjack, it manifests as the house edge of around 0.5% with optimal play. Sportsbooks apply vig by offering uneven odds, such as -110 on both sides of a bet, meaning players must risk $110 to win $100. Poker rooms collect vigorish as rake, typically 5% of the pot up to a capped amount. These mechanisms guarantee the house extracts value over volume.
Vigorish in Australian Gambling Context
Australian players see vigorish in licensed online platforms through disclosed RTP rates, often 92-98% for pokies, implying 2-8% house edge. Table games like baccarat charge 5% on banker wins. Regulators mandate clear display of these figures to inform bettors. Vigorish differs from explicit fees; it is the statistical edge ensuring casino sustainability while allowing short-term player wins.
Practical Examples Across Game Types
In roulette, vigorish equals the house edge of 2.7% on European wheels due to zero. Sports betting vig totals 4.55% on -110 lines. Poker rake might be $3-$5 per $100 pot. Players calculate effective vigorish to compare games; lower vig favours long-term play. Awareness aids informed decisions without altering inherent odds.
