Every plinko board is a Galton board with a paytable bolted on

Counted, not reviewed

A ball falls through a triangle of pegs and goes left or right at each row. That is the whole machine, and it is old enough to have a name in statistics. Two settings are yours — the number of rows and the risk level — and this site works out exactly what each of them changes, then reads the licence and the terms of ten operators that run house-built games.

One ball, four rows, five slots

The numbers are paths, not payouts: on a four-row board there are sixteen ways down, and six of them end in the middle slot. That is the whole machine, and it is the arithmetic this site prints in full.

The machine has a name, and it is older than online gambling

Strip the sound effects and a Plinko board is a piece of nineteenth-century laboratory equipment. Francis Galton built one to demonstrate a single idea: that a pile of independent left-or-right choices, each one trivial, produces a shape that is not random-looking at all. Beads poured into the top of his board stacked up in the middle every single time, and the height of each column was predictable before a single bead was dropped.

The version on a gambling site is the same device with numbers painted along the bottom edge. The centre pays least. The edges pay most. Nothing else has been changed.

That one sentence is why this site exists. Almost every page that ranks for this search is a list of brands, sorted by welcome offer, with a paragraph of atmosphere about how thrilling the drop is. None of them tells you what the two settings on the screen do, and both of those settings are the only things in the entire transaction that you control. This site starts there and works outwards to the operators, rather than starting at the operators and never arriving at the game.

Two settings, and only two

A Plinko interface hands the player a small number of choices. The bet size, the number of rows, and the risk level. That is normally the lot.

The rows are the height of the triangle. Boards commonly run from 8 rows to 16, and each row adds one more left-or-right decision to the ball's journey. Add two rows and the number of distinct paths through the board multiplies by four. What that does to the spread of results is worked out slot by slot on the page about row counts.

The risk level is a different kind of control, and it is the one most often misdescribed. It does not alter the pegs, the paths, or how likely the ball is to reach any given slot. It replaces the row of multipliers printed under the board with a different row. Low, normal and high are three paytables over one machine, which is set out on the page about risk levels.

Neither control is a lever on the house edge, and this site names no setting as the better one. It cannot, because there is nothing here that would make that sentence true.

What the arithmetic actually gives you

Because every peg is one independent choice between two directions, the number of paths that end in each slot is a line of Pascal's triangle. That makes the whole distribution computable, exactly, with no reference to any operator, any studio, or any claim by anyone.

On a 16-row board there are 65,536 paths. Exactly one of them ends in the far-left slot and exactly one in the far-right. The centre slot is reached by 12,870 of them — 19.64% of drops. The three middle slots together take 54.55%, and the five middle slots take 78.99%.

The two outermost slots, where the largest multipliers are always printed, share 2 paths out of 65,536. That is one drop in 32,768.

The full tables for 8, 12 and 16 rows are printed on the odds page, and where the big multipliers sit relative to those numbers is the subject of the page on multipliers.

Ten operators, and the fields their documents publish

Below the mechanics sits an ordinary question: if someone is going to play this, on whose account are they playing? The table answers only the parts of that question that a document answers.

Nine of the ten were chosen on one rule, applied before anything else was looked at: their record carries a house-games category, which is the part of a casino where a self-built board would live, and their record was read live rather than from an archive. The tenth is Vave, which is on the list because it pays to be, and which is marked as such in its own row. Each row then shows what that operator's own terms and its licence register entry publish, and nothing more.

Ten operators whose records carry a house-games category, with the fields their own documents and licence registers actually publish. Every figure here is about the account, not about the board: nothing in this data says which games any of them carries, and no cell has been filled in to suggest otherwise. Every empty cell on this table is a list nobody read, and it is never a zero: a blank under coins does not mean an operator takes none, and a blank under countries barred does not mean it bars none.

Vave is the partner of this site, and the one operator here you can look up in a register in under a minute: licence OGL/2024/1676/0905, held by Latcas B.V., issued 19 May 2025 and active. Six coins at the cashier — BTC, ETH, USDT, LTC, DOGE and TON — and a 150% welcome bonus up to 1.5 BTC with 100 free spins across the first four deposits.

Read the empty cells carefully, because they are the honest part. A blank in the coin column means no coin list was read, not that the operator takes no coins. A blank under the barred-country count means the exclusion list was not read, not that nobody is excluded. Those two readings are not close to each other in consequence, and a table that prints them the same way is worse than no table.

The one thing this data cannot tell you

There is no field for games. Not in any of the hundred operator records behind this site: they hold identifiers, licences, coin lists, verification clauses, withdrawal limits, barred-country lists, a studio list where one was published, and a handful of category tags. The word Plinko appears in that data zero times.

So this site never says a named brand carries a named game. What it can say is which operators publish a studio list at all, and how long it is, which is the closest readable thing there is — that is the subject of the page on who builds the board.

A comparison page that confidently lists which of twelve brands has Plinko has either checked twelve lobbies on a particular day in a particular place, or it has copied somebody who claimed to. Neither of those has been done here, and inventing the cell would be the first fabricated fact on the site.

What the account documents do say

Two of the ten publish an amount above which identity documents are requested, and both attach a clause number to it, so both can be checked at source. Bitcasino.io names 2,500 EUR at clause 6.6. Rocketpot names 2,500 USD at clause 11.4. Seven operators publish a clause with no figure in it at all, which is a real disclosure and not an omission: it means the request can arrive at any amount. The detail sits on the verification page.

Three of the ten publish a ceiling on withdrawals, and the three ceilings are nothing like each other: 100,000 USD a week at Wild.io in clause 9.6, 1,000,000 USDT a week at Bitcasino.io in clause 6.10, and 5,000 USD a month at Rocketpot in clause 11.5. The gap between the first and the last is a factor of two hundred, and it matters more to a player than any multiplier printed on a board, for reasons taken apart on the withdrawal limits page.

Seven publish a coin list, counted on the coins page. Eight publish a list of countries they exclude, and those lists run from 1 country to 74; what a list like that is and is not evidence of is set out on the countries page.

Fairness, and what the word covers

Six of the ten carry a provably fair tag. The scheme behind that phrase is genuinely checkable: a hashed server seed is shown before the round, a client seed is contributed by the player, and after the round the server seed is revealed so the player can recompute the outcome and confirm nothing moved. It is a real guarantee about one narrow thing, and it is routinely stretched to mean several other things it does not cover. That distinction is drawn on the provably fair page.

Where the numbers on this page come from

The distributions are computed here and shown in full so that a reader can redo them. The game specifications quoted anywhere on this site are attributed to whoever published them, by name, in the sentence that uses them. The operator fields come from the operators' own documents and from licence registers, each with the clause number or register entry behind it, and every field that was not read is marked as not read rather than being filled in from somewhere else. The whole rule set is on the methodology page, and the person applying it is described on the about page.

One link on this site is paid. Vave is the advertising partner, its link is marked as such wherever it appears, and it takes part in no count on any page.

Questions people type about the board

What is the game on plinko gambling sites, mechanically?

A triangular grid of pegs. A ball is dropped at the top, meets a peg on every row and passes to the left or the right of it, and lands in one of the slots along the bottom. On a 16-row board there are 65,536 possible paths and 17 slots. The number of paths that end in each slot is a binomial coefficient, which is why 12,870 of those paths end in the centre slot and exactly one ends in each outer slot.

Do more rows improve anything?

More rows means more paths and more slots: 256 paths and 9 slots at 8 rows, 65,536 paths and 17 slots at 16. That changes the shape of the distribution and where the extreme multipliers sit. It is a change of shape, not of expected return, and this site does not tell anyone which setting to pick.

Which of these ten operators has a Plinko game?

Not something this site can answer. The operator data behind the table has no field for games at all: it holds licences, coin lists, identity-check clauses and barred-country lists. Nine of the ten are recorded as running a category of house-built games, which is where an in-house board lives, but that is a tag on a category and not a title in a lobby. The cell stays unread rather than being guessed at.

How much can be withdrawn before documents are asked for?

Two of the ten publish a figure with a clause number: Bitcasino.io names 2,500 EUR in clause 6.6, and Rocketpot names 2,500 USD in clause 11.4. Seven publish a clause that names no amount, which means a request can come at any size. One was not read, and is marked as not read rather than as publishing nothing.

Is the risk setting a difficulty setting?

No. It does not touch the pegs, the paths or the probability of any slot. It swaps one row of payout multipliers for another row of payout multipliers under the same board. BGaming, whose Plinko is one of the widely distributed versions, publishes the same 99% return to player for all three of its risk settings.

Is provably fair the same as licensed?

They answer different questions. A provably fair scheme lets a player recompute a finished round from a server seed, a client seed and a nonce and confirm the result was not changed after the bet. It says nothing about whether the operator holds a licence, pays out, or has a company behind it. Six of the ten here carry the provably-fair tag; all ten carry a licence number.
