CalcuttaCalc

Is a calcutta legal?

Some states license them for a $25 fee. At least one treats running them as professional gambling and advertising them as a felony. Most say nothing at all. Here is how to find out which kind of state you are standing in.

This is the question every organizer should ask before the first team goes up, and it is the question almost nobody asks until afterward. The honest answer is that there is no national rule. A calcutta is not legal or illegal in the United States; it is legal or illegal in Montana, in Washington, in Texas, in whatever county you happen to be sitting in — and the answers genuinely contradict each other.

Nothing on this page is legal advice. We are not lawyers, this is a general article, and the law changes. What follows is meant to show you the shape of the problem and give you specific, answerable questions to take to someone qualified where you live.

Two states, opposite answers

The clearest way to see how wide the gap is: look at two states that have both addressed calcuttas directly and arrived at opposite conclusions.

Montana: permitted, with a permit

Montana's Department of Justice regulates calcuttas explicitly and publishes guidelines and an FAQ for organizers. In Montana a calcutta is an auction pool conducted by an organization authorized by the department — meaning you apply, you get a permit, and then you may run one.

The conditions Montana attaches are worth reading closely, because they are a fair sketch of what a regulator worries about:

Washington: illegal, and advertising it is a felony

Washington runs the other direction. The Washington State Gambling Commission has stated plainly that calcutta tournaments are illegal in the state, describing them as an auction-pool wagering system in which participants bid on players, the highest bidder wins the rights to that player, and payouts follow that player's performance — a fair description of every calcutta ever run.

The Commission points to RCW 9.46.0269, the professional gambling statute, and — this is the part organizers do not expect — to RCW 9.46.240, under which advertising such a tournament online constitutes a class C felony.

In October 2025 the Commission issued a cease and desist notice to an unlicensed operator running calcutta billiards tournaments and promoting them on Facebook. The Commission's own framing included a line every host should sit with: participants may not even know they are wagering illegally.

Read those two states next to each other and the lesson is not "calcuttas are risky." It is that the same event, run the same way, is a permitted charitable fundraiser on one side of a state line and a felony advertisement on the other. Geography is doing all the work.

The three buckets your state probably falls into

Broadly, states land in one of three places.

1. Expressly regulated

A statute or a gaming authority addresses calcuttas by name, usually alongside raffles and charitable gaming. Montana is the clean example. If you are in one of these states, your job is easy: read the rules, file the form, follow them. The regulator has already told you what it wants.

2. Expressly prohibited

The state treats pooled wagering on a contest as gambling, and no charitable exemption reaches a calcutta. Washington is the example. The risk here is not theoretical — it is a cease and desist letter, and potentially worse for whoever advertised.

3. Silent

Most states are here, and it is the hardest place to be, because silence is not permission. What usually applies instead is the state's general definition of gambling, which nearly always has three elements: consideration (you paid something), chance (the outcome is not entirely within your control), and a prize. A calcutta has all three on its face. Whether an exemption rescues it — for private social wagering, for bona fide contests of skill, for charitable fundraising by a registered nonprofit — is exactly the question a local attorney can answer and a general article cannot.

The questions actually worth asking

If you take nothing else from this page, take this list to whoever you ask:

That last one catches people. In Washington the advertising is its own offense. A poster on a feed store corkboard and a Facebook event are not the same legal object in every state.

A separate problem if it's a golf calcutta: amateur status

Golf carries a wrinkle that has nothing to do with criminal law. The USGA discourages participation in calcuttas, and the concern is amateur status. Its position is that the format blurs the line between playing for prize money — not allowed for amateurs — and gambling, which is.

The USGA's own language is that it may inform players they have forfeited their amateur status, or deny them entry to USGA championships and places on USGA international teams, where their golf gambling activities are considered contrary to the best interests of golf.

So a member-guest calcutta can be perfectly lawful in your state and still be a problem for the one player in the field with a college season ahead of her. If you are running a calcutta at a club with competitive amateurs in it, that is worth a conversation before the auction, not after. Our guide to running a calcutta at a golf tournament covers the format side.

Who should be asking

The organizer. Not the app, not the auctioneer, not the person who bought the winning team.

If your event benefits an arena fund, a scholarship, a 4-H club, a volunteer fire department, or a booster club, start with them. Groups that fundraise regularly usually already know their state's charitable gaming rules, often have a compliance contact, and sometimes already hold the permit you would otherwise need to apply for. Asking them costs one phone call and is a far better first move than a search engine.

If you are running a private calcutta among people who know each other — no public advertising, no rake, no charity, everyone settling between themselves — you are in a different posture than a publicly promoted event with a house cut, and in many states a meaningfully safer one. But "many" is not "all," and the difference between those two events is worth understanding precisely rather than approximately. Our guide on whether the organizer should take a rake gets into why that cut changes the character of the thing.

Where CalcuttaCalc sits in this

Nowhere, deliberately, and it is worth being blunt about why.

CalcuttaCalc cannot take, hold, move, or pay out money. That is not a feature we have not built yet; it is the design. Operating real-money wagering through an app requires gambling licenses in every jurisdiction it touches, and we do not have them and do not want them. What the app does is arithmetic: it records what teams sold for, tracks who pledged what into which syndicate, and computes who owes whom when the results come in.

That means using CalcuttaCalc does not make your calcutta legal, and it does not make it illegal either. It has no bearing on the question. The legality of the pool lives entirely with the organizer and the jurisdiction. A scorekeeper does not change what is being kept score of.


CalcuttaCalc is not a betting service, and it can't be used as one. Operating real-money wagering through an app requires gambling licenses — we don't have them and the app is built so it never needs them: it cannot take, hold, move, or pay out money. It's a scorekeeper for private social auctions; whatever stakes exist live entirely between you and your group, offline. Social wagering laws vary by state and country — the organizer is responsible for keeping the game legal where they live. For participants 21+. If gambling stops being fun, call or text 1-800-GAMBLER.
