Ten pounds across three hundred rounds, and the 3.33p it leaves

Two numbers are published on this key and the useful figure is the one between them. Ten pounds goes across a cashier. Three hundred rounds come back. Ten pounds shared among three hundred rounds is ten thirds of a penny for one of them, which this bill prints as 3.33p to the nearest hundredth and which is exactly a third of what the neighbouring key charges for a count of a hundred. That is a price of admission per round, and admission is the only thing a deposit actually buys.

The reason this section can print such a figure at all, and no other section of this site can, is that somebody paid. A count handed over for nothing has no price per unit to find, so the only question that can be asked of it is what its rounds return. Here a real sum meets a real count and the division is a fact rather than an inference. Three figures follow from it, and all three are printed on this bill: 3.33p of admission a round, what one of the three hundred comes to once a turnover condition has crossed it, and what the same three hundred would have cost with nobody giving anything away.

The last of those three is the figure this publisher exists to print and that seven other publications working the same key have no way to reach, since none of them carries a paid column at all. At a 10p round and a return of 96 per cent this publisher’s own two figures, three hundred rounds funded out of a reader’s balance cost £1.20 across the whole count. Every step from that £1.20 up to £17.28 is set out in the parts below, and no step uses a figure whose source is unstated.

What none of the arithmetic needs is the name over the lobby door. Which artwork a count is credited on, and which firm drew it, changes no input in any sum here, so no figure on this bill is traced to a title or to a maker. Four things settle the whole of it: how many rounds there are, what one of them stakes, what proportion of staking comes back, and how much turnover is demanded before the balance converts. Of those four, the promotion prints the first and nothing else.

What the tenner does as a deposit, which is not what it does as a key

A tenner does two distinct jobs on this key and they have to be priced separately or one of them gets charged for twice. As a key it unlocks a count of three hundred. As a deposit it becomes ten pounds of balance belonging to the reader, available to stake, and withdrawable in principle on whatever terms the cashier has written down. Nothing has been bought. A condition has been satisfied.

Take the deposit on its own to begin with. Turn ten pounds over once in a game giving back 96 per cent stated here, not read and £9.60 comes home, so one turn of the money has charged 40p. Expense arrives with repetition rather than with size: turn the shrinking balance four times and about £1.51 has gone, turn it a hundred times and almost nothing remains, which is the entire mechanism of a return below a hundred per cent. Somebody who deposits, collects the count and never stakes the tenner itself has been charged nothing for admission at all, beyond any fee a cashier levies on moving money, and this key publishes no such fee so this bill shows none.

Now take the deposit as a key, which means setting the £10.00 beside what the count comes to. Three hundred rounds finish at £17.28. Read the tenner as a price and the bargain looks cleared with £7.28 over. That reading goes wrong in the detail that matters, since the tenner has gone to nobody, so the £7.28 is not a gain but the amount by which the count outruns what the door asked for. Per round it reads cleaner still. The door wanted 3.33p a round and the count delivers 5.76p a round, leaving 2.43p a round on top.

One route does exist by which the offer spends the deposit rather than merely holding it against the count, and this bill will not price it. Where terms reckon the turnover against the deposit as well as the credited funds, the base swells from £28.80 to £38.80 and ten times of it wants £388.00 of staking instead of £288.00. No published word from the regulator addresses a condition built that way no example exists, so the quantity is named here and no total is drawn from it.

Thirty pounds of face on a ten pound door, and £28.80 of balance

A count turns into money as soon as a stake is attached to it. Three hundred rounds at 10p put £30.00 at stake, and that £30.00 is the face of the count. It is three times the sum that opened the door, which is the single most striking thing about this key: a tenner buys admission to thirty pounds of play. The leverage of face over door is three to one here, one to one on a hundred-round count for the same tenner, and four to one where two hundred rounds come for a five pound deposit.

Neither of the two figures that turn a count into a sum is published by anybody. Nothing in any rulebook puts a value on a free round no source sets a round’s value, which makes the 10p a statement of this publisher’s and it is said to be one wherever it is used. The second is the proportion coming back, and 96 per cent is an everyday figure for machines of the kind such counts land on: read off no screen, fixed to no title, and owned by this publisher in each sentence that spends it.

With both in hand the face resolves. Thirty pounds of turnover at 96 per cent returns £28.80, so £28.80 is what three hundred rounds hand to the balance and £1.20 is what the return keeps. On the free side that £1.20 comes off the offer’s stake rather than the reader’s, the rounds having staked themselves, which is why the free column shows no money going in at the top of the instrument.

What £28.80 amounts to is a line in an account with a condition laid over the top of it. It is not three hundred rounds of winnings in any sense a reader may act upon, and taking it for that is the commonest way a bought count gets overvalued. Part four is about the condition, and the condition claims £11.52 of the £28.80 before a penny of it converts.

A last figure sits naturally under this heading, since it is arithmetic on a published duty rather than a judgement. On a British licence a slot is barred from taking above £5 inside one game cycle from anybody who has reached twenty-five slots alone, off the sheet. The 10p used here divides into that figure fifty times, so three hundred rounds raised to the cap would put £1,500.00 at stake rather than £30.00. The count reads the same in both cases. Only the stake, which nobody prints, settles which of those two faces a reader has been handed.

Ten times of £28.80, and the £11.52 that goes in meeting it

One input decides most of this page and it is the input least likely to be on the screen when a reader is deciding. Putting a balance through a required volume of turnover before it converts is priced by E = B × (1 − W × (1 − RTP) ∕ g), which takes the balance already in hand, the volume of turnover demanded of it as a multiple, the proportion of staking a game gives back, and the weight at which a qualifying game counts towards the demand. Feed it £28.80, ten, 96 per cent and full weight, and £17.28 survives.

Ten is not a figure plucked out of the market. It is the furthest point a British licensee may reach, a ceiling live since 19 January 2026 off the rule sheet and attached to every kind of licence but the technical and the software ones. Where a round’s winnings land as bonus funds, turnover upon those funds sits beneath that ten. Whether the ceiling catches a free round in itself is a question the regulator has answered nowhere in print, and this bill leans neither way on it. Since no lawful demand exceeds ten, working at ten yields the smallest free column British terms can produce: £17.28 is where three hundred given rounds begin and not where they end. Anything the rules allow below that ten leaves a larger balance standing and widens the £18.48 with it.

The weight a qualifying game carries is the input a promotion most often omits altogether. Where no percentage is printed, this bill reads the silence in the reader’s favour and puts the weight at full, repeating as much at each point where the figure is used. Reading it any other way moves the finding violently rather than slightly: with a qualifying weight of thirty per cent, a rate one respondent put to the regulator in its own consultation a respondent’s rate, not the regulator’s, ten times of turnover on £28.80 demands more than the balance can bear and the free side falls away to nothing. That working is this publisher’s, laid on a rate somebody else quoted.

The tally is the argument of this bill in three lines. One tenner, three counts, and a finding that rises in exact proportion to the count while admission falls in exact proportion to it. Nothing in the middle column is a term anybody publishes: each figure is ten pounds divided by the count beside it. Nothing in the right-hand column depends on the count being large or small either, since every line is worked at the same stake, the same return and the same ten times of turnover.

Above ten times the arithmetic turns quickly. Twenty times leaves the £28.80 at £5.76, twenty-five times leaves it at nothing, and beyond that point the expression turns negative and is held at nought, no balance being able to surrender more than all of itself. Twenty-five is accordingly the number to carry: it marks where a 96 per cent return, taking 4p from each pound of staking, has swallowed everything the count handed across. A cashier outside the British licence answers to no ceiling, so no rulebook anywhere keeps an offer of this shape on the near side of twenty-five.

Three hundred rounds bought outright at the same 10p

The second sum takes one line of working and wants no multiple whatever. Three hundred rounds funded at the reader’s own 10p send £30.00 through the game and bring £28.80 of it back, so the count costs £1.20. That £1.20 is the whole charge. Nothing was advanced, so nothing is owed: the winnings bear no condition, no published limit stands over them, and whatever the three hundred rounds take is money from the moment it arrives.

A pound and twenty pence for three hundred rounds strikes most readers as too small, and the reason is that cost follows turnover rather than balance. A return of 96 per cent takes 4p out of each pound staked, and three hundred rounds at 10p stake thirty pounds once. The charge becomes large only when the same money is cycled, which is precisely what a turnover condition arranges: ten times on £28.80 sends £288.00 through the game, and 4p a pound of that is £11.52. So the free side is handed £28.80 and gives up £11.52 of it, while the paid side stakes £30.00 and gives up £1.20.

Stated bare, the mechanism is this. The cost of a count equals the turnover it produces multiplied by the shortfall in the return. A given count produces a fixed amount of turnover when it is paid for. The same count produces that much turnover plus the whole volume the condition demands when it is handed over. Whether the free side still finishes ahead is then a question about one number, and that number is the one a reader is asked to accept before it has been shown to them.

Two cautions belong beside the £1.20. It is an expectation rather than a result: three hundred actual rounds will land above it or below it, and nobody at this publisher has pressed any of them. And it assumes the thirty pounds passes through once, which is what three hundred rounds at 10p do, so a reader who carries on staking the £28.80 that came back is charged again on that pass at the same 4p in the pound. Neither caution disturbs the comparison, since both sides are worked at one stake and one return.

Why a bigger count moves admission and never moves the worth

Here is the finding this key exists to deliver, and it is a property of the arithmetic rather than a feature of any promotion. What one round of a credited count comes to, after the turnover condition has crossed the balance, is the stake multiplied by the return multiplied by whatever fraction the condition leaves. At 10p, 96 per cent and ten times, that is 5.76p. The count does not appear in it anywhere. A hundred rounds are worth 5.76p each, three hundred rounds are worth 5.76p each, and a thousand would be worth 5.76p each.

Admission, by contrast, is the deposit divided by the count, so it moves with every extra round. Ten pounds over a hundred rounds is 10p of admission. Over two hundred it is 5p. Over three hundred it is 3.33p. So the whole difference between the three bought counts in this section lies on the admission side, and a reader comparing them is comparing doors and not rounds.

That yields a test any reader may apply to a count of this shape. Divide the deposit by the count. An answer above 5.76p means the door is charging more a round than a round delivers at this bill’s figures, and an answer below it means the count clears the door. A hundred rounds for ten pounds fails by 4.24p a round. Three hundred rounds for ten pounds clears it by 2.43p, while two hundred rounds behind a five pound door clear it by 3.26p.

three hundred rounds worth £17.28 given and minus £1.20 bought, £18.48 between the two figures, 184.8 rounds of the same distance, and 3.33p of admission against 5.76p a round delivered

The test has a hinge in it and the hinge is the multiple, not the count. Every figure in the paragraph above is worked at ten times of turnover. At twenty times a round is worth 1.92p and all three doors in this section are expensive by that measure. At twenty-five times a round is worth nothing and the admission price is the only real number left on the page. So the honest form of the test is conditional: at the best multiple British terms allow, three hundred for a tenner is the cheapest of the three doors, and at a multiple nobody has shown the reader, none of the three doors is cheap.

Both forms of the distance are worth carrying away. £18.48 states the count’s worth as a receipt. One hundred and eighty-four point eight rounds states its worth as play, and that is the form in which a reader actually meets it: whoever took the count and whoever left it alone stand that far from one another once the condition has been satisfied.

Four British duties set against a count this size

All of the above is arithmetic on an offer that nobody obliges to take any particular shape. British licensing obliges plenty, and what repays the effort there is not recitation: take four duties, set each against a figure already struck above, and print what the duty is worth in that figure.

One worked example the regulator publishes itself lands squarely on a tenner. Set a daily figure of £10 beside a weekly figure of £100 and the tighter of the pair rules, so the account is held to a tenner inside any day, and to £70 once a week is reckoned the regulator’s illustration. A reader holding that pair could reach this key’s door once in a day and seven times in a week, and no oftener. Offshore nothing obliges a cashier to offer the facility, to make setting one the standing choice, or to hold an increase back for a day before it bites.

Two of those four duties can be carried into the arithmetic and two cannot. The ceiling is a number, so it yields £17.28. The withdrawal rule is a prohibition with the regulator’s own forbidden wording attached, so it can be laid beside the ten pounds and shown to cover it. The bar on mixing and the limit facility govern the shape of an offer and the fittings of an account, and neither produces a sum, so both stand as duties with no total drawn off them. Where they are missing a reader loses a protection and not a figure, and this bill marks which sort of loss belongs to each duty.

What is unprinted, what is unstruck, and where a demo sits

Five figures build the free column and they fall into two groups. Three are this publisher’s: the 10p a round, the 96 per cent returning, and the ruling that an unprinted qualifying weight counts in full. Two are the offer’s: the count, which this key does print as three hundred, and the multiple, which no offer on the key prints anywhere.

Part four meets the missing multiple by standing on the ceiling instead of choosing a number, and those are not the same move. A ceiling is published, a reader may look it up, and standing on the heaviest lawful demand bounds the finding from below, so £17.28 is a floor and not an average. A number chosen for being usual could be looked up nowhere, and a believable quantity sitting where an absence belongs does more harm than the absence itself, since an absence can be tested and a believable quantity cannot.

Two further quantities are away and this bill totals neither. One is a cap on what credited rounds may win, for which no rule and no published source exists, so where an offer carries such a cap the finding becomes whichever of the two numbers is smaller and this bill cannot say which. The other is what the turnover is reckoned against, named already in part two, where stretching the condition over the deposit lifts the demand from £288.00 to £388.00.

The case needing none of this belongs at the end. Play in a demonstration build costs nought and pays nought, invariably, cash having no route out of a demonstration at all, and five hundred pounds showing on such a balance is worth nothing whatever. That is the floor under every page of this domain, and it explains why a bought count earns the work: three hundred rounds against a tenner is a rare thing here, something with real arithmetic to it, and the arithmetic answers £17.28 at the very least against £1.20 of plain charge.

The neighbouring keys finish the set. The same tenner for a hundred rounds is this door at triple the admission. Five pounds for two hundred rounds is a cheaper door onto a middling count. And the keys in this section naming a floor and no count at all put a different question, a floor being the price of permission rather than of play.
