One penny of return is the whole question, and nobody prints it twice

1

The only question a handset genuinely raises about a reel

A sibling page in this part of the site settles what a smaller screen does to a cashier and to a conditions document, and the answer there is that it moves two quantities and leaves a long list alone. This page asks something narrower and harder, about the build rather than about the till: could the reel itself be a different machine, and would anybody be able to tell.

Set the arithmetic down first so the question has something to be worth. A credit of £40.00 under a forty times clause asks £1,600.00 to cross the reels. Where 96 pence comes back in each pound, the margin keeps £64.00, which puts the expected close at minus £24.00. Every figure in that sentence rests on the return, and the return is the quantity under examination.

Now suppose the handset build of the same reel returned 95 pence rather than 96. The staking is unchanged at £1,600.00, because a clause counts pounds and not builds. The margin now keeps £80.00. The close is minus £40.00. One penny of return, laid over the obligation a written clause already created, has moved the answer by £16.00.

That £16.00 is the whole stake of the argument and it is worth seeing how small the input was. Nothing about the clause changed. Nothing about the credit changed. Nothing about the count of presses changed. A single hundredth, in a quantity nobody is obliged to print, carried four tenths of the credit with it.

So the page has three jobs and they come in order. Work out which of the figures behind a press could in principle differ between a build drawn for a desk and a build drawn for a hand. Work out which of those anybody publishes, and whether any of them is published twice over, once for each. Then price the gap the second answer leaves.

The conclusion is given here rather than withheld, because a reader deciding whether to read on deserves it. Almost nothing is published per device. Of the quantities that could differ, the expensive ones are published nowhere for any build and the cheap ones are published inside whichever build is being held. The question therefore sits nowhere in writing, which is the sixth place and the only one with no address.

Eight quantities behind one press, and which could differ by build

Take a press apart into the quantities that decide what it does. Each one gets three questions: could two builds of one reel honestly carry different values for it, does anybody publish it at all, and is it ever published once for a desk and once for a hand. The third column is the one that empties out.

The table splits three ways rather than two, which is the useful result. Four quantities could differ and are published nowhere whatever the screen. Two could differ and are readable inside whichever build is open, which makes them per-device in the only sense that pays. Two could not differ at all, because a published rule holds them.

Notice where the money is. The first four rows carry the return, the swing, the frequency of a paying result and the contribution rate, which between them decide the whole of what £1,600.00 of staking does. The two readable rows carry a prize schedule and a ladder of stake rungs, which decide how a press is configured rather than what it is worth in expectation.

So the quantities a reader can settle for their own build are precisely the ones that matter least to the subtraction, and the quantities that decide the subtraction are settled for nobody. That is the same ordering this site keeps meeting, arriving here through a question about hardware rather than through a question about documents.

Four quantities capable of differing between two builds, and none of the four stated for either

One row deserves a note before the arithmetic starts. The contribution rate sits in the first group here although other pages on this site put it in a schedule a reader can sometimes open. Both are true: where a table of rates exists it can be read, and it is published for a game rather than for a rendering of a game, so it answers nothing about the question this page is asking.

What a single penny of return is worth, computed twice

Price the first row of the table, because it is the expensive one and because it can be priced exactly. Hold the credit at £40.00 and the clause at forty times, so the staking stays at £1,600.00 whatever the return is. Then move the return by one penny in the pound and watch what the obligation does with it.

Route one works through the credit. At 96 pence back, forty lots of four hundredths add to 1.6, a credit holds whatever one less that comes to, and six tenths of £40.00 pointing downwards is minus £24.00. At 95 pence back, forty lots of five hundredths add to 2.0, so the whole £40.00 points downwards. The two closes are minus £24.00 and minus £40.00.

Expected close at the 96 pence per pound assumed here minus £24.00 Expected close one penny of return below that minus £40.00 What a quantity published for no device is worth £16.00

Route two never touches the credit at all. Take the staking on its own: £1,600.00 should come back as £1,536.00 where 96 of every 100 pence returns, and as £1,520.00 where 95 do. The difference between those is £16.00, which is the same figure the credit route produced, reached without the credit appearing anywhere in the working.

Expected return on £1,600.00 of staking at 96 pence £1,536.00 Expected return on the identical staking at 95 pence £1,520.00 The same sixteen pounds, reached without the credit £16.00

Two blocks printing one figure is not decoration. The first route could be wrong if the house formula were misapplied; the second could be wrong if the staking were miscounted; they share no step and they agree, which is as much verification as arithmetic of this kind admits of. Both rest on the 10p press, the 96 pence return and the forty times clause this leaf assumes, and on nothing else.

Reduce the figure to its smallest form and it becomes portable. One penny of return across one pound of staking is a penny. At the 10p press this site assumes, that is one tenth of a penny per press, which is £1.00 for every thousand presses. The device question has exactly that price and no other, however large the credit on the advertisement happens to be.

Three pence of range across those rows moves the close by £48.00, which is £16.00 a penny all the way down the column and is therefore linear. A reader who cannot establish the return to within a penny cannot establish the close to within £16.00, and a reader who cannot establish it to within three pence cannot establish the close to within £48.00.

Every bar on that drawing carries the same rule down its left side, because every one of the four readings is settled in the same place, which is nowhere. The drawing therefore prices a spread rather than a condition, and the spread exists because an input is missing rather than because a clause is harsh.

The break-even travels with the return, and travels by five

The multiple where a credit’s value runs out is not a market figure. It is however many times the margin goes into a pound, so at 96 pence back it is twenty-five, at 95 pence twenty, at 97 pence thirty-three and a third, and at 94 pence sixteen and two thirds. That single column does more damage to the device question than anything else on this page.

Read the last column downwards and a clause of twenty times is generous, thin, exactly worthless and actively costly, in that order, without one word of the clause being altered. The written condition is a constant across all four rows. What moves it from generous to costly is an unpublished property of whichever build the credit is spent across.

Put the same point in the units a reader has. Somebody holding a twenty times clause cannot say whether 40 per cent of their credit survives or whether 20 per cent of it is owed, and the entire difference between those two answers is three pence of return. On a £40.00 credit that spread runs from plus £16.00 to minus £8.00, which is £24.00 of uncertainty attached to a condition that reads as perfectly definite.

This is the sharpest consequence of the absence and it is worth stating in one line. The multiple is published and the figure that makes it meaningful is not, so a published multiple is an incomplete statement rather than a term a reader can price, and it is incomplete by the same amount on either build.

Say the honest qualification alongside it. A difference of three pence between two renderings of one reel is this page’s illustration, chosen to show the mechanics at a size that can be read, and nothing found for this site suggests a spread of that size exists between builds. The arithmetic shows what the question is worth if the answer is not nought. It does not claim that the answer is not nought.

Figures a build is not free to vary, and what pins them

Two of the eight quantities cannot differ between renderings on a licensed build, and the reason is worth following because it shows what a published rule is good for. Inside the British licence a reel build keeps 2.5 seconds in hand before another cycle may begin. That interval attaches to a game cycle, and a game cycle is a thing the game does rather than a thing the screen does.

Work it out in this page’s own figures. £1,600.00 of staking at the 10p press assumed here is 16,000 presses, and 16,000 presses at that interval occupy 40,000 seconds at the least, or eleven hours six minutes before anything else is counted. That figure is identical on a desk and in a hand, because neither the press value nor the interval has a screen in it.

16,000 presses and eleven hours six minutes at the shortest, identical on either rendering of one reel

The ceiling over a single cycle behaves the same way, and the drafting makes the reason explicit. What the instrument caps is identified by what the game does, namely turning images until their arrangement settles a prize, and by the fact of its being played online. Hardware is absent from the whole definition, so a build cannot step outside the ceiling by changing shape.

Three further rules in the same family hold a build to one behaviour whatever it is drawn on. Every cycle takes a separate commitment of its own, so nothing rolls forward unasked. No control may be offered that fetches a result up early, which disposes of turbo, quick spin and slam stop together. And where what comes back is no larger than what bought it, the build may not celebrate, so a sub-stake result cannot be dressed as a win on either screen.

Set those five against the four unpublished quantities from part two and the asymmetry is plain. Everything about a build that is fixed by a published rule is fixed identically for both renderings and can be checked by anybody. Everything about a build that decides the expected close is fixed by whoever wrote the maths and is checkable by nobody. The line between the two groups is not a line about devices at all.

That asymmetry is this page’s quietest finding and probably its most useful. A reader worried that a handset reel runs faster, autoplays, lets a result be rushed or dresses up a losing spin has, on a licensed build, four published answers and all of them are no. A reader worried that it returns a penny less has no published answer of any kind.

What the build in a hand does publish about itself

Two rows of the table in part two came back as readable, and they are readable in an unusual way: not in a document somewhere else but inside the thing being used. A prize schedule and a ladder of stake rungs both live on an information screen belonging to the build, which means whichever rendering a reader has open is publishing its own figures for itself.

That is the only per-device publication this page found, and it is worth naming precisely because it is easy to overclaim. Nothing is published comparatively. No source sets a handset schedule beside a desk schedule and invites a comparison. What exists is a schedule for the build in hand, which answers what that build pays for a combination and says nothing at all about the other one.

Price what that is worth and the answer is honest rather than flattering. A prize schedule decides how a press is configured. It does not give a return, because converting a schedule into a return needs the probability of each combination and the schedule does not carry it. So a reader holding the one readable document still cannot reach the figure that moves £16.00.

The stake ladder is worth more than it looks, and for a reason this page can compute. A build offering rungs at 10p, 20p and 50p but not at £1 forces a £1,600.00 obligation into at least 3,200 presses rather than 1,600, and at the interval in part five that is 8,000 seconds against 4,000. The ladder therefore sets the clock the same way a per-cycle ceiling does, from inside the build rather than from a clause.

Read the third column and the pattern completes itself. Everything a build publishes about itself describes a mechanism. Nothing a build publishes about itself describes a rate. Mechanism is cheap to disclose and tells a reader how to play; rate is expensive to disclose and tells a reader what it costs, and just one of that pair ever reaches the screen.

None of this is about where the information sits or how many presses it takes to reach it, which is a measurement a sibling page makes and this one does not repeat. The point here is simply that the readable material and the expensive material are different material, and that no amount of opening screens converts one into the other.

Hunting a per-device figure, and the shape of what is missing

An absence needs evidence before it can be priced, so here is what was looked for and what came back. The question was whether any primary source reachable from this site states a return, a swing, a frequency or a contribution rate separately for a handset rendering and for a desk rendering of one reel. No such source was found, and no rule was found obliging anybody to produce one.

Three negatives make up that answer and they are different sizes. The first is that no source states a return per device. The second is that no source states a return per build at all in a form this site could cite. The third is that no rule anywhere requires either, which means the first two are not oversights waiting to be corrected but the settled position.

The third negative is the one with consequences, so it needs stating carefully. The standard governing what a customer must be able to find out about their chances before committing is satisfied by any one of several different disclosures, only one of which is a return figure. A build can therefore meet it without printing a return at all, and nothing in it is addressed to a screen size.

Four rows of nothing is an answer, not a dead end, and it is what puts this whole subject in the sixth place. A quantity with no address is not a quantity somebody has hidden. It is a quantity nobody has any duty to produce, which is a different complaint and a more durable one.

What follows for a reader is a rule about assumption rather than a figure. Faced with two renderings and no information distinguishing them, the only defensible move is to treat them as identical, and to record that the assumption is unverifiable and is worth £16.00 a penny if it turns out to be wrong. That is how every unstated quantity on this site gets handled, and this one is no exception.

There is an asymmetry inside that assumption worth printing. Assuming the builds identical is the kindest available reading, in the same way that assuming full contribution towards a wagering clause is the kindest available reading. Unstated quantities on this subject run in one direction, and a reader who assumes the generous answer is never the party who has to correct it.

What the disclosure standards ask of a game, screen or no screen

Britain does write rules about what a build has to show, and they are the right family of duty to set against part seven. The standard on game information wants enough put within easy reach, before anybody commits, for a customer to judge their chances, and it offers a choice of ways to do it: a statement of the way a game arrives at its winners, or the house margin, or the return, or the odds on the events that pay.

The disjunction is the part that matters here and it is routinely misread. Because any one of those satisfies the standard, a licensed build may publish a description of its mechanism and no rate at all, which is precisely the split part six found on the information screen. The standard is met, the reader is informed about the mechanism, and the £16.00 remains unreachable.

Three companion limbs in the same standard govern the rest of the screen, and each answers a line of part six. One puts a full and correct account of the rules within reach of somebody who has not committed yet, which is what makes a prize schedule evidence at all. One asks a running game to keep enough on view for its own state to be followed. One puts the prizes, or the means of arriving at them, in that same reachable place before anything is committed.

Two limbs of the randomness standard bolt the back door. Once a game has begun, its rules, its payouts and the probabilities underneath them are all pinned where they stood, and the guidance names a term letting rules be rewritten whenever the operator pleases as drafting that fails. A result, when it comes, goes on screen correctly and stays there long enough to be taken in.

What none of those duties does is mention a device, and the omission is not an oversight either. They are written about a game and a customer, and a rendering is neither. So the British rulebook does exactly what part seven found the market doing: it governs the build thoroughly and has nothing at all to say about which screen the build is drawn on.

Acting on a question that cannot be settled either way

A page that ends in an absence still owes a reader something to do, and there are four things here, in order of what they are worth. The first is to stop treating the device as a variable in the arithmetic, because nothing establishes that it is one and the clause, the credit and the staking are identical regardless.

The second is to open the information screen on the build actually in use and read the prize schedule and the stake rungs off it. Those are the only figures published for a rendering, they take a minute, and the stake ladder in particular decides the clock: 10p rungs against £1 rungs turn a £1,600.00 obligation from 1,600 presses into 16,000, and eleven hours six minutes at the shortest rather than one hour six.

The third is to notice which of the figures in any guide are being presented as properties of a handset when they are properties of a clause. A multiple is a clause. A ceiling in pounds is a clause. A withdrawal floor is a payment screen. None of the three acquires a device-dependent value by being met on one, and a sentence claiming otherwise is a sentence about a column this page could not find.

The fourth is to carry the price of the unknown rather than resolving it. Sixteen pounds a penny, on a £40.00 credit at forty times, is the size of the thing nobody will tell anybody. Written beside the close as an unresolved band rather than folded into it, it keeps the arithmetic honest: minus £24.00 on this page’s assumption, and a band of £16.00 either side of that for every penny of return the question leaves open.

Set that band against the clause for a final sense of proportion. Forty times took a £40.00 credit to minus £24.00, a movement of £64.00, and the whole device question is worth £16.00 a penny on top of it. The written condition is the larger quantity by some distance, and it is also the one printed where somebody can go and read it.

That is the honest conclusion and it is not the exciting one. The reel is almost certainly the same reel, the arithmetic is certainly the same arithmetic, and the only thing this page can prove is that nobody has published enough to say so. Where a question has a price and no answer, printing the price is all anybody can do with it.
