Gambling is not legal in Hawaii. The state bans almost every form of it — no casinos, no state lottery, no sports betting, no horse or dog racing, no slot machines, and no commercial card rooms. Hawaii is one of only two states with a near-total prohibition, and the offenses in Hawaii Revised Statutes Chapter 712 run from a misdemeanor for placing a bet to a class B felony carrying up to ten years in prison for running an operation. The only relief in the statute is a narrow social gambling defense that requires meeting five specific conditions.
What Hawaii Treats as Gambling
The statutory definition is deliberately broad. Under HRS Chapter 712, you gamble when you stake something of value on the outcome of a contest of chance or a future event outside your control, hoping to gain something in return.1Justia. Hawaii Revised Statutes 712-1223 – Gambling That language covers poker, sports wagers, lottery tickets, pool-style betting, and any pay-to-play scheme that awards prizes by chance.
The law also defines what it means to “advance” gambling, which matters because promoting carries far heavier penalties than participating. You advance gambling if you materially help the activity along: setting up the game, maintaining the space, recruiting players, handling money, keeping records, or knowingly letting someone use property you control to run a game.1Justia. Hawaii Revised Statutes 712-1223 – Gambling
Sweepstakes-style promotions can cross into gambling territory too. The dividing line is whether entry requires payment. A legitimate sweepstakes offers a free way to enter. Once participants must pay for a chance to win, it starts to look like a lottery, and Hawaii has no legal lottery.
Penalties: Three Tiers Based on Your Role
Hawaii’s penalties scale sharply by what you did, not just that you gambled. Someone who places a bet faces a misdemeanor. Someone who runs the game faces a felony. People regularly mix up which tier catches which conduct, and the gap matters.
Simple Gambling
Knowingly participating in any gambling activity is a misdemeanor under HRS 712-1223.1Justia. Hawaii Revised Statutes 712-1223 – Gambling A misdemeanor conviction can bring up to one year in jail and a fine of up to $2,000.2Justia. Hawaii Revised Statutes 706-663 – Sentence of Imprisonment for Misdemeanor and Petty Misdemeanor Possessing gambling records used in bookmaking or lottery schemes is a separate misdemeanor at the same penalty level.3Justia. Hawaii Revised Statutes 712-1225 – Possession of Gambling Records in the Second Degree
Promoting Gambling in the Second Degree
Negligently advancing or profiting from gambling activity is promoting gambling in the second degree, a class C felony under HRS 712-1222.4Justia. Hawaii Revised Statutes 712-1222 – Promoting Gambling in the Second Degree “Negligently” is the key word. You do not need to intend to promote gambling; a failure to use reasonable care is enough. A conviction carries up to five years in prison and a fine of up to $10,000.5Justia. Hawaii Revised Statutes 706-660 – Sentence of Imprisonment for Class B and C Felonies This tier catches people like landlords who knowingly rent space for gambling, or someone who provides equipment to a game they are not running.
Promoting Gambling in the First Degree
The most serious gambling charge targets organized operations. Promoting gambling in the first degree is a class B felony under HRS 712-1221. It applies when a person recklessly advances or profits from gambling by:
- Running a bookmaking operation that takes more than five bets totaling over $500 in any seven-day period
- Handling lottery or pool money received from someone other than a player whose chances those funds represent
- Receiving more than $1,000 in any seven-day period in connection with a lottery, pool, or other gambling enterprise
Any one of those triggers is enough.6Justia. Hawaii Revised Statutes 712-1221 – Promoting Gambling in the First Degree A class B felony conviction means up to ten years in prison and a fine of up to $25,000.5Justia. Hawaii Revised Statutes 706-660 – Sentence of Imprisonment for Class B and C Felonies On top of a conviction, any property used in illegal gambling, including stakes, records, and equipment, is subject to forfeiture.7Justia. Hawaii Revised Statutes 712-1230 – Forfeiture of Property Used in Illegal Gambling
The Social Gambling Defense
Hawaii carves out one narrow path for private play, and it is worth reading carefully. Under HRS 712-1231, social gambling is an affirmative defense rather than an outright exemption. The activity is still technically prohibited; you raise social gambling as a defense if you are charged, and you bear the burden of proving it.
To qualify, all five conditions must be met:
- Every player competes on equal terms, with no house edge
- Nobody profits from hosting the game — only from winning as a player
- The game does not take place at a hotel, school, public park, or any business establishment
- No minors participate
- The activity is not bookmaking
Every condition.8Justia. Hawaii Revised Statutes 712-1231 – Social Gambling Definition and Specific Conditions, Affirmative Defense A casual poker night at a friend’s home where nobody takes a rake and everyone plays by the same rules will usually qualify. A weekly game at a bar where the owner takes a cut of each pot will not, even if the stakes are small.
Online Gambling and Sports Betting
Hawaii’s statutes were written before internet gambling existed and do not mention it by name. But the definition of gambling is broad enough to cover it: staking value on a chance outcome is gambling whether it happens at a table or through a screen. No Hawaii court has carved out an exception for online activity, and law enforcement treats the prohibition as applying.
Enforcement is a separate question. Hawaii residents can technically reach offshore gambling sites, and the state has limited tools to block those transactions. That gray area does not make the activity legal. It means prosecution is less likely for an individual bettor than for someone running a local operation.
Sports betting has come closer to legalization than any other form of gambling in the state. In 2025, a sports betting bill cleared both the Hawaii House and Senate for the first time before dying in conference committee over the tax rate. A new bill, HB 2570, advanced out of a House committee in the 2026 session on a narrow vote, proposing at least six online sportsbook licenses with a 15% tax on adjusted gross revenues. It still needs to clear additional committees, both chambers, and the governor before it becomes law. If you are planning around the assumption that sports betting will be legal in Hawaii soon, that assumption is premature.
If You Gamble Legally Somewhere Else
Traveling to a jurisdiction where gambling is legal does not end your Hawaii obligations. Residents who gamble legally in other states or countries still owe taxes on their winnings. Gambling income is taxable as ordinary income at the federal level, and Hawaii requires residents to include gambling winnings in state gross income. Unlike many states, Hawaii does not allow you to offset winnings with losses. Casinos and other payers report certain winnings directly to the IRS on Form W-2G, but you are legally required to report your winnings whether or not a W-2G is issued.9IRS.

Bringing lottery tickets home can also create federal exposure. Under 18 U.S.C. § 1301, transporting lottery tickets across state lines, mailing them, or helping someone in one state buy a lottery ticket from another can bring up to two years in federal prison.10Office of the Law Revision Counsel. 18 U.S. Code 1301 – Importing or Transporting Lottery Tickets Buying a ticket while you are on the mainland is one thing; having tickets regularly shipped to you in Hawaii is another.
Federal Charges on Top of State Charges
Anyone running a gambling operation in Hawaii faces federal exposure in addition to the state felonies. The Wire Act makes it a crime for anyone in the gambling business to use phone lines or the internet to transmit interstate or international bets, wagers, or betting information for sporting events, with up to two years in federal prison.11Office of the Law Revision Counsel. 18 U.S. Code 1084 – Transmission of Wagering Information; Penalties The Illegal Gambling Business Act reaches larger operations: conducting, financing, managing, or owning any part of an illegal gambling business can bring up to five years in federal prison. The statute typically applies when the operation involves five or more people and either has been running for more than 30 days or takes in more than $2,000 in a single day.12Office of the Law Revision Counsel. 18 U.S. Code 1955 – Prohibition of Illegal Gambling Businesses An organized gambling ring in Hawaii can be prosecuted at both levels for the same conduct.
