Illegal gambling in California is regulated under Penal Code 330 PC, which prohibits certain types of betting games known as banking or percentage games.
While social gambling is generally legal, any game involving a house or operator taking a cut of the bets can result in criminal charges.
Even participating in an illegal game—not just running it—can lead to prosecution.
Understanding the distinction between legal and illegal gambling is critical if you are facing charges or under investigation.

What Is Illegal Gambling Under Penal Code 330?
Penal Code 330 PC makes it a crime to deal, play, operate, or conduct certain prohibited gambling games.
The law targets games where:
-
a house or operator acts as the “bank,” or
-
a percentage (rake) is taken from wagers
This includes games played with:
-
cards
-
dice
-
mechanical or electronic devices
-
money, credit, or anything of value
Banking Games vs. Percentage Games
Understanding these two concepts is essential to determining whether gambling is illegal.
Banking Games
A banking game occurs when:
-
the house collects money from losing players
-
the house pays winnings to other players
The operator essentially acts as the central financial participant in the game.
Percentage Games
A percentage game occurs when:
-
the house or organizer takes a portion of each wager
-
the profit comes from a “rake” or commission
Even if players compete against each other, the presence of a rake makes the game illegal under PC 330.
Legal vs. Illegal Gambling in California
Not all gambling is illegal in California.
Legal Gambling
-
private social poker games with no house profit
-
friendly betting among individuals
-
games where all players compete equally without a rake
Illegal Gambling
-
games where a host takes a percentage of bets
-
organized gambling operations with a house bank
-
underground poker games with a rake
The key distinction is whether anyone profits from operating the game.
Examples of Illegal Gambling
Examples of conduct that may violate Penal Code 330 include:
-
hosting poker games and taking a percentage of each pot
-
operating a gambling house where the house pays winners
-
dealing or managing games involving a rake
-
knowingly participating in games where the operator profits
