Juice is one of the terms you’ll encounter in both the gambling and betting industries. It refers to the fee the casino or bookie charges you for playing with them.
The most common casino example is when the house takes a small cut of your poker winnings every time you win a pot.
For example, in a poker cash game, you might win a $200 pot, but before the dealer pushes casino chips your way, they’ll take out $5. This is the juice that helps keep the games running.
