Two extra rows quadruple the paths and add two slots

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.

The selector is a shape control

Rows are the height of the triangle. Nothing about the pegs changes when you move the selector; there are simply more of them, in more rows, and the ball makes one more decision for each row added.

Two quantities move when it does. The number of possible paths, which is 2 raised to the number of rows, and the number of slots, which is the number of rows plus one. The first grows explosively and the second grows by one at a time, and the gap between those two growth rates is the whole story of this setting.

Every figure in that table is a binomial coefficient divided by a power of two. None of it depends on an operator, a studio, or a claim by anyone, and the whole derivation is on the page about the mechanism.

Adding rows flattens the middle and stretches the ends

Read the centre column of the table from top to bottom. At 8 rows, better than one drop in four lands in the single centre slot. At 16, it is closer to one in five.

That is not because the ball has become less inclined to the middle. It is because the middle has been divided among more slots. The whole distribution is spread across 17 positions instead of 9, so no single position holds as much of it.

The three slots at the centre of a 16-row board together take 54.55% of drops, and the five centre slots take 78.99%. So four fifths of the outcomes land in under a third of the width of the board. The other twelve slots share what is left, and the further out you look the thinner it gets: 2.78% for the slot four steps out, 0.85% at five steps, 0.18% at six, 0.02% at seven, and 0.0015% at the edge.

The full column of figures for each row setting is printed on the odds page.

The edge gets 256 times rarer between 8 rows and 16

This is the number that most descriptions of the row setting leave out, and it is the one with teeth.

Reaching the far-left slot means going left at every single row. On 8 rows that is 1 sequence out of 256. On 16 rows it is 1 sequence out of 65,536. The outer slot has not moved; it has become 256 times harder to reach.

Which is exactly why the multipliers printed there are larger on the taller board. A paytable is written against a distribution, so a slot that is reached a quarter as often can carry four times the payout without changing what the paytable is worth overall. Bigger numbers at the ends of a 16-row board are a consequence of the arithmetic above, not an extra generosity, and what those numbers look like is on the multipliers page.

What the row setting does not change

It does not change the house's margin. The row count fixes the probabilities and the paytable fixes the payouts, and the return to player is a property of the two together — decided by whoever wrote the game, not by the selector on the screen.

It does not make any slot more likely relative to its neighbours in any way you could exploit; the shape is symmetric and fixed before the ball is dropped.

And it does not interact with the other control on the screen. Switching rows and switching risk are independent operations on two different objects: rows change the distribution, risk changes the paytable, which is set out on the risk levels page.

This site names no row count as preferable. It cannot, and it will not, because there is no arithmetic here that would support such a sentence.

Where the specification figures come from

Anything on this site about a particular game — the 8-to-16 range, a stated return to player, a maximum multiplier — is a specification of that one version and is named as belonging to it, never carried across to another board. This reading has not opened the studio's own page, so those figures are reported as the specification that circulates for the game rather than as something checked at source. The path and probability figures are different in kind: they are computed here from the row count alone and printed in full so that any reader can redo the arithmetic and check it.

That split between computed and quoted runs through the whole site, and the rules are on the methodology page.

Underneath the mechanics sit the operators, and what they publish about accounts rather than about games — licence numbers, coin lists, identity checks — is compared on the home page. What the identity clause says in particular is on the verification page.
