Fish table games are illegal in most U.S. states, where law enforcement and courts generally classify them as gambling devices rather than skill-based arcade machines. The answer isn’t uniform, though. Gambling law is set state by state, sometimes county by county, and whether a specific machine crosses the line depends on the test your state uses to separate skill from chance. Federal law can also reach operations once they grow past certain size and revenue thresholds.
Why Fish Tables Usually Count as Gambling
Nearly every state defines gambling using three elements: consideration, chance, and prize. You pay something to play, the outcome depends at least partly on luck, and you can win something of value. If all three are present, it’s gambling. Remove any one and the activity is generally lawful.
Fish tables clearly involve consideration and prize. You feed money into the machine, buy credits to fire a virtual cannon at fish worth different point values, and cash the resulting points out for money or prizes. The fight is almost always over the third element. Operators market the games as skill-based because aiming and timing matter. Prosecutors counter that the fish move on randomized patterns, that hidden payout algorithms decide whether identical shots register as hits, and that no amount of practice gives a player control over those variables. In most courtrooms that have looked closely, the second argument wins.
Skill vs. Chance Depends on Your State’s Test
States don’t apply a single rule for deciding when chance makes a game illegal. Three approaches dominate, and the one your state uses often determines the outcome.
- The predominance test, used by most states, asks whether chance is the dominant factor. If skill matters more than luck, the game is legal. This is the test fish table operators prefer, because they can point to experienced players outperforming beginners.
- The material element test asks whether chance affects the outcome to a material degree, even if skill also plays a role. A game can be mostly skill-based and still qualify as gambling if randomness meaningfully shapes results.
- The any-chance test is the strictest. If luck influences the outcome at all, the game is gambling. Fish tables almost always fail this standard.
Appellate courts in several states have already ruled that specific fish table games are predominantly games of chance. Operators brought in expert witnesses to argue that players improve with practice, but the courts concluded that the random elements built into the software outweighed any skill advantage. Even where aiming matters, the machine’s internal algorithms decide whether a shot lands, and that is chance regardless of how the product is marketed.
When Federal Law Gets Involved
Gambling enforcement is mostly a state job, but two federal statutes can reach fish table operations once they grow.
The Illegal Gambling Business Act
Running an illegal gambling business is a federal crime punishable by up to five years in prison. A fish table operation triggers the statute when all three of these are true at once: it violates the gambling law of the state where it operates, it involves five or more people who run, finance, or manage it, and it has either been operating for more than 30 days or taken in more than $2,000 in gross revenue in a single day.1Office of the Law Revision Counsel. 18 U.S. Code 1955 – Prohibition of Illegal Gambling Businesses A solo operator with one machine won’t be charged under this provision. A chain of parlors with employees and steady revenue easily qualifies.
The Johnson Act
The Johnson Act makes it a federal crime to transport gambling devices across state lines or to possess them in states where they’re illegal. The statute defines a gambling device as any machine that delivers money or property based on an element of chance.2Office of the Law Revision Counsel. 15 U.S. Code 1171 – Definitions If courts in your state have found that fish tables are chance-based devices, shipping those machines into the state can expose manufacturers, distributors, and buyers to federal charges.
Online and Sweepstakes Versions
Physical storefront machines aren’t the whole picture. Online platforms now run fish table games through a sweepstakes model. Rather than placing a direct cash bet, you buy virtual currency and receive sweepstakes entries that can be redeemed for prizes. The structure is designed to strip out the consideration element, because you’re technically buying coins rather than wagering.
Whether that workaround holds depends on where you live. Some states accept the sweepstakes model. Others treat it as gambling in a different costume, especially when the virtual currency has no real purpose beyond conversion back to cash. A growing number of states have passed laws aimed at sweepstakes operators, and online fish tables fall squarely within those laws.
What Operators Risk
Operators face the heaviest penalties. In states that treat illegal gambling as a misdemeanor, fines and short jail time are typical. In states where organized or large-scale operations are felonies, prison sentences of several years are possible. Police routinely seize the machines themselves along with any cash inside them during raids, and for operators running multiple locations those forfeitures alone can mean losses of tens or hundreds of thousands of dollars. Federal charges under the Illegal Gambling Business Act add up to five years in prison and additional fines.1Office of the Law Revision Counsel. 18 U.S. Code 1955 – Prohibition of Illegal Gambling Businesses
If you operate these machines, the first thing to do is read your state’s gambling statutes and any local ordinances. Lack of enforcement in your area right now is not the same as legality. Jurisdictions that have ignored fish table parlors for years have also been the sites of coordinated raids that shut down dozens of locations at once.
What Players Risk
Players usually face lighter consequences than operators, but lighter doesn’t mean none. In many jurisdictions, playing an illegal gambling game is itself a misdemeanor. Fines tend to be modest, but a conviction still goes on your criminal record. If you’re inside a parlor during a raid, you can be detained, and any winnings on you can be seized as evidence. A storefront that looks legitimate and has operated unbothered for months offers no protection if the state decides your machine is an illegal gambling device.
Taxes on Any Winnings
Even where fish table games operate legally, winnings are taxable income. The IRS treats gambling winnings from any source as fully taxable, and you have to report them on your return whether or not you receive a W-2G form.3IRS. Topic No. 419, Gambling Income and Losses Starting in 2026, gambling establishments must issue a Form W-2G for winnings of $2,000 or more.4IRS. Instructions for Forms W-2G and 5754 (Rev. January 2026)
Most fish table parlors operating in a legal gray zone issue no paperwork at all. The IRS doesn’t care. You owe tax on the winnings whether anyone documents them or not. Cashing out regularly without reporting the income stacks a tax problem on top of whatever gambling exposure you already have. Losses are deductible, but only up to the amount of your reported winnings, and only if you itemize.
