A public ledger is not a jurisdiction. It is a database with a consensus rule. If a product takes something of value, offers a prize, and decides the prize by chance, the fact that a contract did the accounting does not turn the product into a puzzle. It may make the accounting easier to subpoena.
This is a dual-regime map, not a memo from a lawyer. Nothing here is legal advice. Laws differ by country, by state, by whether money changed hands, by whether the operator is local, and by whether a prosecutor slept well. If you need a decision, hire counsel in the place you actually live and the place the product actually operates. Ante will not pretend a blog post replaces that.
What we can do is name the two regimes that keep getting collapsed in crypto marketing: game publishing and gambling. Onchain sits underneath both. It does not pick one for you.
Two machines, both happy to use a chain
A game, in the everyday sense, is a system of rules people enter for play. Money might sit at the edges: a box price, a cosmetic, a tournament buy-in that funds a prize pool among identified competitors. Chance might sit inside the rules: dice in a board game, a shuffled deck, a critical hit. The combination is old. It does not automatically make the Tuesday night table a casino.
Gambling, in the sense regulators reach for, is a commercial offering of a stake, a prize, and a result driven predominantly by chance — especially when a house takes a cut or stands on the other side of the bet. The vocabulary varies: lottery, gaming, betting, pool, casino. The pattern repeats.
Onchain tech can implement either machine. A fully onchain chess match with no stake is a game with a public board. A slot implemented as a contract with a VRF and a token vault is a chance product with a public RNG. Calling both "onchain games" is how the types article earns its keep.
Dual regime: MiCA is not a casino licence
Think in two stacks, not one "web3" stack.
Publishing a game looks like: age ratings, consumer law, app-store rules, loot-box guidance in some countries, advertising standards, IP licences. In the EU, the Markets in Crypto-Assets Regulation (MiCA) can apply to a token as a crypto-asset. That is a market-conduct and issuer regime. MiCA does not licence a casino. A white paper that talks about a utility token does not, by itself, authorise a house that takes stakes on chance.
Offering gambling looks like: a national (or state) gambling licence, or a decision to stay out of a territory. KYC, responsible-gaming tools, advertising bans, geoblocking, capital requirements, dispute processes. The chain might hold the bankroll. The licence still talks about a person.
A studio that ships a skill game with optional cosmetics lives in the first stack. A product that lets you stake tokens on a verifiable spin lives in the second. A product that muddles them — "it's just a game" on the homepage, a cash-out on the wallet page — is asking two regimes to look away at once.
Onchain dice is not a hall pass. Putting the stake in a contract does not move the activity out of gambling law. It may give an investigator a public log.
The three-part test you will keep meeting
Many common-law places, especially in the United States, analyze an illegal lottery or unauthorized gambling with some version of three elements:
- Prize. Something of value comes out.
- Chance. The result is determined predominantly by chance, not skill.
- Consideration. Something of value went in.
If all three are present, you are in gambling-or-lottery territory until an exemption says otherwise (state lottery, licensed casino, social gaming with no cash-out, fantasy sports under a specific statute, and so on). If one element is missing, prosecutors and platforms still argue about it — "free to enter" with a paid shortcut, "skill" that is actually a reel, "no prize" that is a token with a market.
This test is not universal. Some countries licence "games of chance" and "games of skill" on different axes. Some treat any stake on a future uncertain event as betting. Some care whether the house is a counterparty. Some care about advertising. Some care about minors. The three parts are a flashlight, not a passport.
Skill versus chance is a fight about the dominant factor
Chess is skill. A coin flip is chance. Everything in the middle is litigation.
A game can include chance without being "a game of chance" under a given statute. A game can advertise skill and still be chance-dominant if the skilled player cannot reliably beat the house edge. Pay-to-win can look like skill to a marketer and like a stake to a regulator.
Crypto adds two favorite arguments, both overused:
- "The contract is autonomous, so there is no operator." Someone still wrote it, deployed it, hosted the frontend, held the admin key, or took a fee. Autonomy of matching is not absence of a business.
- "The token is not money." If people pay for it and cash it out, many regimes will not find that sentence impressive. Some will. Do not learn which from a thread.
Provably fair is not a defence
Provably fair means you can check that a seed was not swapped and that a published formula was applied. It does not mean kindness, odds, no house, a licence, or onchain settlement.
A prosecutor does not need a hidden last move to care. A checkable house edge is still a house edge. Verification is not a gambling licence, not a MiCA authorisation, and not a reason to skip geoblocking as if the chain were a flag of convenience.
Play-to-earn does not turn a prize into a wage either. Emissions are not a hall pass.
What "not legal advice" is doing on this page
It is doing the boring job: stopping a reader from treating a taxonomy as permission.
We can say, as mechanics writers, that a public rulebook can still be a brutal rulebook, and that putting a contest on a blockchain does not remove the legal line. We cannot say your token is a utility, your minigame is skill, or your jurisdiction "doesn't care because it's DeFi." Those sentences are legal conclusions. They belong to lawyers who know your facts.
Geoblocking a frontend is not the same as making a contract uncallable. That gap is now a cliché. It is also the sort of cliché that shows up in enforcement stories. Ante is not going to diagram how to thread it.
If you are a player, the practical translation is smaller. If you must put up value to receive a chance at more value, you may be gambling. If you are underage, stop. If you cannot afford the stake, the cryptography will not save the month. Onchain or off, the responsible line is the same: set a limit, and do not treat a verification hash as a green light.
Close the spine
Onchain means the record can be public. It does not mean the activity is unregulated. Games and gambling are different regimes that can share a ledger, a VRF, and a soundtrack. The line between them is drawn in law, with messy tests about prize, chance, and consideration — not in a white paper's glossary.
The vocabulary for that record started at the hub: how-onchain-games-work. Are the rules on the chain, or only the receipt? Ante will keep explaining the machines. It will not run one.
This page names no operators. It is not a destination list. It is not a licence.
