What is Considered Illegal Gambling in California?

Posted by Ronald D. HeddingFeb 04, 2026

In California, gambling itself is not automatically illegal. Many forms of social gambling—such as home poker games—are perfectly lawful.

However, gambling becomes a crime when it crosses into “banking” or “percentage” games, as defined under California Penal Code § 330.

Illegal gambling charges often surprise people because the activity may look like a harmless card game. But when a house, bank, or rake is involved, California law treats the conduct as a criminal offense—even if no one makes a profit.

California Penal Code § 330 – Illegal Gambling Explained

Penal Code § 330 PC makes it a misdemeanor to deal, play, conduct, open, or carry on certain prohibited gambling games, whether for profit or not.

The statute targets games where:

  • A bank or house pays winners and collects from losers, or

  • The operator takes a percentage (rake) of the bets

You need not own or operate the game to be charged. Participating in a known illegal game may be sufficient.

What Is a “Banking” Game?

A banking game is one where:

  • A house or operator covers bets

  • Losers pay the house

  • Winners are paid from the house's funds

Classic examples include:

  • Blackjack

  • Faro

  • Roulette

  • Monte

The presence of a house acting as the financial intermediary is what makes the game illegal—not the betting itself.

What Is a “Percentage” Game?

A percentage game occurs when:

  • The house or organizer takes a cut (rake) from each pot or wager

  • The rake is calculated as a percentage of bets

This is where many poker games cross the legal line.
A social poker game is legal—but the moment someone takes a rake, it becomes illegal gambling under PC 330.

🎬 The movie Molly's Game illustrates this perfectly: high-stakes poker was legal until a rake was introduced.

Is Social Gambling Legal in California?

Yes. Social gambling is legal if all of the following are true:

  • No house or bank exists

  • No rake or percentage is taken

  • Players bet against each other only

  • The organizer does not profit

This includes friendly poker, card, or betting games among friends.

What Are the Penalties for Illegal Gambling?

Illegal gambling under Penal Code § 330 PC is a misdemeanor.

Potential Penalties Include:

  • $100 to $1,000 in fines

  • Up to 6 months in county jail (per count)

  • Summary (informal) probation

Judges often impose probation rather than incarceration, especially for first-time offenses.

Additional Consequences:

  • Criminal record

  • Possible asset forfeiture

  • Enhanced penalties if other crimes are involved

An expungement is typically available upon completion of probation.

Legal Exceptions to California Gambling Laws

Certain gambling activities are explicitly exempt from Penal Code § 330.

Charitable Gambling

Non-profit and charitable organizations may conduct:

  • Bingo

  • Raffles

  • Fundraising poker games

These must comply with California charitable gaming laws.

Tribal Casinos

Gambling conducted on Native American tribal lands is governed by federal and tribal law—not Penal Code § 330.

Related Crimes Often Charged With Illegal Gambling

Illegal gambling cases frequently involve additional charges, including:

Federal charges may apply if the gambling operation is large-scale or interstate.

Common Defenses to Illegal Gambling Charges

Illegal gambling cases are very defensible with the right legal strategy.

You Were Not Playing a Banking or Percentage Game

Prosecutors must prove the presence of a bank or rake. If the game was purely social, charges may fail.

You Did Not Know the Game Was Illegal

Knowledge is required. If you were unaware a rake or bank existed, you may not be guilty.

The Game Fell Under a Legal Exception

Charitable events or tribal gaming operations are lawful.

Illegal Search and Seizure

Police must follow search-and-seizure rules. Evidence obtained through unlawful searches may be suppressed.

Can Illegal Gambling Charges Be Avoided?

Yes—often before charges are even filed.

An experienced defense attorney may be able to:

  • Negotiate DA rejection (no charges filed)

  • Secure diversion or probation

  • Reduce or dismiss charges entirely

Early legal intervention is critical.
