Copies, fees and empty promises

Plinko scams: the marks of fake plinko apps and promises

A falling-ball board is easy to copy, and that is exploited in apps and adverts. Here are the signs that separate a copy from a real game, and the checks you can make on your own.

Plinko scams rarely concern the game itself. They are about apps, websites and adverts that borrow the look of a ball board but lack everything that makes gambling verifiable: an operator with a name, a licence number you can look up, a table and a way of checking the rounds. The board is only scenery.

Here we work through the most common schemes, how they tend to build up, and what you can check yourself before you send a single krone or coin. If you would rather compare real operators with licences and terms, the whole overview is on the home page of the Kryptospill comparison.

The three values that decide a provably fair round, and the check you can make afterwards. The check shows that the round was not altered; it says nothing about the house edge, the caps or the payout.

Three kinds of plinko scam you should recognise

The app that is meant to give you an income

The first kind is presented as a way of making money, usually with words such as «passive income» or «earn while you relax». You download an app, drop balls and watch the balance rise. The balance is only a figure on the screen. When you want to take it out, a new demand appears: watch more adverts, reach a higher amount, or recruit friends.

Gambling cannot be a source of income. The house has a built-in margin, and over many rounds the average moves in the house's favour. An app that describes plinko as work or wages is describing something other than a game.

The promise of certain winnings

The second kind sells a method. It can be a «strategy», a program claimed to know where the ball will land, or a person in a chat group sharing «tips». What they all have in common is claiming to know an outcome that cannot be known beforehand.

In a seed-based house game the round is decided by a server seed that is kept hidden until it is replaced, combined with a client seed and a round number. No outside tool can see the hidden value. Anyone selling foreknowledge is therefore selling something that does not exist.

The fee before withdrawal

The third kind is the one that costs most. You have apparently won a large amount. To get it out you first have to pay a «charge», an «activation fee», a «currency conversion» or a deposit to «unlock» the account. Pay, and a new demand arrives.

A regulated casino takes any fees off the balance or states them in the terms. It does not ask you to transfer new money to release money you already have. Such a demand is the clearest warning on this whole page.

The marks of a plinko scam: a short checklist

Work through the points below. If you answer yes to one of them, you should stop:

The service describes the game as a job, income or an investment.
Someone guarantees winnings or shows «today's winners» with large amounts and no source.
You have to pay something extra to get a win out.
There are no terms, or the terms do not name a company.
There is no licence with a number and an issuer.
Contact happens only through chat with one person who presses you.
You are asked to send cryptocurrency to a private wallet instead of to a cashier on the site.

None of the points above concern the game's mathematics. They concern the frame around it, and that is where the copies give themselves away. A site can have a handsome board with correct multipliers and still be a scheme to get you to pay more.

A worked example for sixteen rows where each pin sends the ball left or right with equal chance. Almost every drop lands near the middle; the large multipliers at the edges are rarely hit, and that is why they can be large.

Check the round: the seed and the table

A real house game with seed checking has a panel where you see the hash of the server seed before you play, can change the client seed, and after a change can recalculate earlier rounds. If you cannot find such a panel, the game may still be real, but then you have no way of confirming the rounds yourself. The whole procedure with the hash, the seed and the nonce is explained on the page about seed checking.

Look for the table too. A serious plinko game shows multipliers for every row count and risk level, and with a little arithmetic you can find the average return yourself. How to work out the probability for each cell is in the explanation of rows and cells.

Remember what the check covers. That a round can be recalculated shows that the outcome was locked before the stake. It does not show that the operator pays out, that the table is favourable, or that the company holds a licence.

Check the operator: the company and the licence

A casino offering gambling with crypto normally gives a company name and a licence number in the terms and at the bottom of the page. You can look the number up with the issuer:

Find the number in the terms, not just in a mark in the footer.
Look it up in the issuer's register. Curaçao licences stand in cert.cga.cw, while licences from Anjouan are looked up in the island's own licence register.
Compare the domain. Is the site you are using listed under the licence?
Compare the company. Is it the same name in the terms and in the register?

Two examples from our own work show why points 3 and 4 matter. Vave holds licence OGL/2024/1676/0905, and the query at cert.cga.cw on 12 September 2026 showed only the domain vavegame.com. Rocketpot writes 1668/JAZ in its terms, while the register showed «invalid» on 12 and 13 September 2026. Discrepancies of that kind do not make a casino a copy app, but they are worth knowing about before you deposit. How we make these queries is described on the method page.

A copy app usually has none of this: no company, no number, no register to look anything up in. Sometimes there is a mark in the footer that looks official but links to nothing, or points to a number that returns no hit. The mark alone is therefore not enough. It is the query with the issuer that counts, and it rarely takes more than a couple of minutes to do yourself.

Demos, free versions and «winnings» you cannot take out

Many fake apps call themselves free. That is not a warning in itself, because real demos exist too. The difference is that a real demo is clear that the balance consists of play money that cannot be withdrawn. It never asks you to pay to turn it into real money. More on what a demo shows and does not show is on the page about a play balance.

If you have already paid

Stop all further transfers, whatever promise of releasing the amount comes with them. Take screenshots of the chat, the app and the payments, and note the wallet addresses and transaction IDs. If you paid by card or bank transfer, contact the bank as early as possible. Crypto transfers can rarely be reversed, and that is why the documentation is the most important thing you have.

Watch out too for «recovery services» that get in touch afterwards and offer to fetch the money back for a payment. That is often a second round of the same scheme.

When the game is real but the playing becomes a problem

Not all harm comes from scams. An entirely real plinko game with a known table can also cost more than you can bear, because the rounds go quickly and the margin works on every one of them. How the house's share grows with the number of rounds is worked out on the page about the return and the margin. Set a limit before you start. Hjelpelinjen (hjelpelinjen.no) gives free help with gambling problems. The age limit is 18.

Frequently asked questions

How do I tell whether a plinko app is fake?

Look at the frame around the game. A copy usually lacks a company name, a licence number and terms, describes the game as income or an investment, and demands payment before you can get a win out. A real house game has a table for each setup and often a seed panel. Find the licence number in the terms and look it up with the issuer. If you find nothing to look up, that is an answer in itself.

Are there programs that can predict where the ball lands?

No. In a seed-based house game the outcome depends on a server seed that is kept hidden until it is replaced. No app, group or person outside the operator's system can see that value before the round. Anyone offering such foreknowledge for payment is selling something that cannot work, and it is often just the entrance to a larger demand later.

Is it normal to pay a fee to take a win out?

A demand to transfer new money in order to release a win is a classic warning sign. At a regulated operator any costs are stated in the terms and are normally taken off the balance. You may be asked for documents for an identity check, but that is something other than paying. If you see such a demand, stop the transfers and gather documentation.

Does seed checking mean I will be paid out?

No. Recalculating a round shows that the outcome was locked before the stake and was not altered. It says nothing about whether the operator pays out, which caps and document requirements apply, how favourable the table is, or whether the company holds a licence. You have to find that in the terms and in the register of the licence issuer.
