A hundred presses for a tenner, and a condition whose size a run decides

1

Which pile of money the condition is written over

Pay £10.00 and take a hundred presses and there are promptly two separate sums in the account. One is the tenner that came out of a bank, sitting where it was put. The other is whatever the presses produce, which does not exist yet and will not exist until the last of them has been used.

Those two sums are different objects, and almost everything on this page follows from keeping them apart. The payment is a known quantity settled on the banner. The winnings are an unknown quantity with a known average, and nothing fixes that average anywhere a reader could look, which leaves it nowhere in writing. The average is also not the thing the condition acts on.

Work the average first, because it is the figure everybody quotes. A hundred presses at the 10p this site supposes throughout commit £10.00 of stake. Ninety-six pounds come back for every hundred staked at the rate carried across this site, so the middle of the range is £9.60.

Now put the condition in. Forty times on £9.60 asks for £384.00 to cross the reels, which is thirty-eight and a half payments of the size the banner asked for. The expected cost of pushing £384.00 round, at four pence held back on each pound, is £15.36, and £9.60 minus £15.36 leaves an expected close of minus £5.76.

Everything in that paragraph is true of the average and of nothing else. Nobody plays the average. A hundred presses produce a number drawn from a spread, and the condition attaches to the number drawn rather than to the middle of the spread, which means the obligation a reader is agreeing to has as many values as the spread has.

That is the whole subject here. A term written over a deposit has a size the moment it is written, because a deposit is a sum somebody chose. A term written over winnings has no size until a run has happened, and the run happens after the agreement. The document is signed first and filled in afterwards, by chance.

A multiplier is not a quantity, and the difference costs money

Read the clause as it is actually drafted, in the bonus terms, and what stands there is a multiplier with no sum beside it. Forty times is an instruction to take whatever lands and multiply. It has the grammar of a figure and the behaviour of a slope, and the two get confused because both are printed as numbers.

Call the outcome X. The staking owed is forty X. The expected cost of pushing forty X round the reels, at four pence a pound, is 1.6 X. What is left of the winnings is X less 1.6 X, which is six tenths of X with the sign turned over. Three statements, all of them exact, and not one of them a sum of money.

Convert to money only by choosing an X, and the choice is what the clause declines to make. At X of £9.60 the staking is £384.00. At X of £96.00 it is £3,840.00. The sentence in the document is identical in both cases, the reader agreed to it once, and the thing agreed to differs by a factor of ten.

£40.00 of staking falls due for each £1.00 the presses happen to hand back

Forty pounds of staking for every pound returned is the clause expressed properly, and it is a rate rather than a bill. Nothing about it is hidden: a reader who opens the document reads exactly that and has understood it completely. Understanding it does not tell them what they owe, because what they owe has not been decided yet.

Compare that with the payment, which is settled in the other direction. £10.00 was chosen by the reader, before anything happened, with full knowledge of the figure. Every term written over the payment is therefore a term whose size the reader fixed. Every term written over the winnings is a term whose size the reels fix, and the reels are not party to the agreement.

The obligation laid out against the run that produces it

Here is the clause drawn as what it is, which is a straight line through the origin. Each row takes an outcome and carries it to the staking owed, the expected cost of working that staking off, and the close. The last column divides the staking by the £10.00 that was paid, since that is the figure a reader thought they were committing to.

The top row is the one nobody writes about and it is the kindest line in the table. Where the presses hand back nothing, the staking owed is nothing, the cost of working it off is nothing, and the close is nothing. A reader in that position has lost the £10.00 they chose to spend and has walked into no obligation whatever.

Run a finger down the final column and the shape becomes uncomfortable. A reader paid £10.00 and the staking the clause produces runs from nought to four hundred times that payment across rows nothing rules out. The better the hour, the heavier the condition, and the heaviness is exactly proportional.

The bars widen as they go down the sheet and that widening is the whole finding. A condition with a fixed figure would draw the same cut on every row. This one draws a cut proportional to the bar, so the gap a reader is agreeing to grows with the only thing they were hoping for.

What an hour that goes well ends up owing

Take the row at £30.00, which is a good but unremarkable hour on a hundred presses. Three times the middle of the spread is not a story anybody tells, and on a build with any spread at all it happens often enough to be ordinary. Here is what it costs.

What a £30.00 run hands back £30.00 What the same clause leaves of it minus £18.00 What the good hour costs to collect £48.00

Forty-eight pounds arrives from either direction without sharing a step. Forty lots of £30.00 is £1,200.00 of staking, and four pence held back on each pound of that is £48.00. Or take the head of the block and remove the foot, £30.00 less minus £18.00, which produces £48.00 a second time. They agree because the condition has exactly one effect, and it works at a fixed rate.

Set that beside the £10.00 payment. A reader who sent a tenner and had a good hour is looking at £48.00 of expected cost to turn the result into money, which is nearly five payments. Nothing has gone wrong, nobody has broken a term, and the figure is entirely a consequence of the run having been good.

Push it once more. A hundred pounds off a hundred presses is the sort of result a reader would describe as the arrangement having worked. Four thousand pounds then has to cross the reels, the expected cost of which is £160.00, leaving an expected close of minus £60.00. The best outcome in the table produces the largest bill in the table.

A ceiling over what bonus money may pay out usually sits in the same document, and it bites only here, in the branch where the hour went well. Pricing one would take a figure, and nothing this site can cite sets a usual ceiling, so this page names the clause and refuses to invent a number for it.

What an hour that goes badly owes, which is next to nothing

The other end of the table deserves equal time, because it is where most readers land and it is genuinely mild. A run of £2.40 off a hundred presses owes £96.00 of staking, costs an expected £3.84 to work off, and closes at minus £1.44. A run of nothing owes nothing at all.

So the condition is not uniformly harsh. It is harsh in proportion, which is a different thing and produces a distribution of outcomes rather than a single verdict. Most readers meet a small version of it, some meet a middling one, and the few who have the hour they were hoping for meet the largest version there is.

That shape is worth naming plainly, because it explains why a clause of this build survives contact with readers. Almost nobody who meets it is badly hurt by it. The people it costs most are the people who had the best time, and they are in no mood to complain about a bill arriving on top of a win.

The middle of the spread, read alone £9.60 The middle after a forty times condition minus £5.76 The gap at one point on a sliding line £15.36

Fifteen pounds thirty-six is the figure that would be quoted if somebody insisted on one number for this arrangement, and the caption on the bottom row says why it should not be. It is a reading at a single point, and the line it sits on runs from nought to as far as a good run reaches. Quoting it as the answer discards the shape that this page exists to draw.

There is also a shortening of the bad branch worth knowing. Where the presses hand back very little, the balance is usually too small for a withdrawal floor met at the cashier, so the clause and the exit agree for once: nothing was ever going to come out. The condition costs that reader nothing because there was nothing for it to act on.

The single property of the clause readable beforehand

If the size cannot be read in advance, something must be, or the document would be pointless. One thing can, and it is the sign. Whether a reader expects to keep any of the winnings at all is fixed by the multiple, and the multiple is printed.

The arithmetic is one line. Each pound crossing the reels leaves four pence behind, so a multiple of W takes four hundredths of W of the winnings. That reaches a whole at W of twenty-five. Below twenty-five a positive share survives, at twenty-five none does, and above twenty-five the clause expects more than the winnings contain.

Forty is sixty per cent past that point, so the expected share is minus six tenths at every outcome. The sign never varies with the run. A £2.40 hour and a £100.00 hour both close at six tenths of themselves in the wrong direction, and the only thing the run changes is how many pounds six tenths amounts to.

That gives a reader exactly one thing to check before agreeing, and it takes a glance. Compare the multiple with twenty-five. Under it, the condition shrinks a win. At or over it, the condition is expected to consume the win and then keep going. Nothing else in the document can be converted into a figure before the presses have run.

Twenty-five is arithmetic rather than market practice, and it moves with the rate of return rather than with anything a business decides. At a lower rate of return it falls, at a higher one it rises, and at the ninety-six in the hundred carried here it sits exactly at twenty-five. Any page on this site that needs the turning point is reaching for the same division.

The honest instruction is narrow, and this page offers no second one. Find the multiple, which is a single click into a second document. Hold it against twenty-five. That single comparison settles the direction of everything else, and no amount of reading settles the amount.

Reading a condition before agreeing to it, and what that is worth here

Advice about bonus offers reduces, almost everywhere, to the instruction to read the terms first. The instruction is sound and this page does not argue with it. What this page argues is that on a condition of this build, reading is necessary and is not sufficient, and the gap between those two words is where the money sits.

A reader who opens the document and reads it carefully knows four things. They know the multiple is forty. They know it attaches to the winnings rather than to the payment. They know the window, if one is written. They know whether a ceiling sits over the bonus balance. Every one of those is a fact and none of them is a sum.

What they cannot know is the thing a person normally means by knowing what they have agreed to, which is how much. The quantity the clause will demand of them is forty times a figure that does not exist at the moment of agreement, and it will not exist until they have finished the hundred presses the agreement was about.

That is an unusual kind of term and it is worth being precise about why. A contract term whose amount depends on a future event is ordinary enough: an interest rate does that, and so does a usage charge. What is unusual here is the direction. The amount owed rises with the outcome the reader wanted, so the term is at its heaviest in precisely the branch the reader was aiming at.

It also puts a cost on a piece of standard advice. A reader told to compare the wagering requirements of two arrangements is being told to compare two multipliers, and multipliers only rank if the quantities they multiply are alike. Where one arrangement hands a reader a hundred presses and another hands them a credit of a stated size, the multipliers are acting on objects of different kinds and the comparison is not what it appears to be.

The practical upshot is a change of question. Instead of asking what the condition will cost, which has no answer before the presses run, ask what it will cost for each pound the presses return. That question does have an answer, it is the same answer for everybody, and on this arrangement the answer is forty pounds of staking and an expected sixteen pence of cost for each pound handed back.

Rules that hold two piles of money apart

Part one split the account into a payment and a set of winnings, and three published British duties act on exactly that split. Each is picked here because it bears on this page’s own two piles rather than on bonus offers at large, and beyond a British licence not one of them reaches anybody.

The first guards the tenner. A licensee is forbidden to impose any maximum whatever on what leaves a deposit balance. The regulator has gone on to publish a model of the wording it will not allow, which caps a day and then caps a week. Bonus winnings are a separate object, and that bar does not stretch across to them. The upshot is tidy and uncomfortable: of the two piles here, the £10.00 is covered and the £9.60 is not, which is the split part one made, reached a second time from a rulebook.

The second asks whether the tenner is still there to guard. Under licence condition 4.2.1, a licensee sitting on customer money has to set out in writing, ahead of any of it being gambled, how that money would fare if the business went under, placing itself on one of the regulator’s four levels and taking an acknowledgement for the answer. The lowest two levels both open with the words not protected. Pick either, and a paragraph that took effect on 31 October 2025 adds a reminder twice a year, carrying the sum then held and needing a fresh acknowledgement before play resumes.

That paragraph earns its place on this page through the length of the obligation. £384.00 worked off ten pence at a time is a great many presses, nobody completes it in an evening, and a reader working off a middling run therefore has money lodged elsewhere for weeks. Twice a year is the only published rhythm at which anybody is obliged to write down what is being held and on what footing, so the slower the staking, the more that rhythm is worth.

The third governs the moment of departure, which a reader reaches on the way out and never sooner. Where a withdrawal has already been requested, no licensed system may hand the customer a route to taking that request back, and the guidance beside the same requirement wants leaving made as smooth as it can be, with the money already requested kept out of reach as a stake. Where an obligation grows with the hour, that rule is worth more than it reads. The better the run, the larger the staking still outstanding, so a path from the exit straight back into play lands at precisely the moment the heaviest version of the condition exists.

A concession, as elsewhere here. An offshore rulebook consulted for this build does want bonus conditions put clearly and does forbid promotion aimed at excessive play, so the position is not a blank sheet. It holds nothing answering to the deposit-balance protection, nothing about declaring how lodged money would fare in a collapse, and nothing keeping a requested withdrawal from being offered back as a stake.

Turning any play-through condition into a rate card

The method here replaces a single figure with three, and the three are stable while the figure is not. Write down the multiple. Divide the rate of return into a margin per pound. Then produce the rate card: staking owed for each pound returned, expected cost for each pound returned, and the share of the return that survives.

On this arrangement that gives forty pounds of staking, sixteen pence of expected cost, and minus six tenths of whatever came back. Those three travel with the clause rather than with the run, so they are true before any press has been made and stay true afterwards. A reader who carries them has everything the document can honestly give them.

Then, and only then, pick outcomes and multiply. Choose the middle, choose a quarter of the middle, choose three times the middle, and print all three rather than one. Printing one is what turns a function into a figure, and a figure is what nobody is actually agreeing to when they accept a multiplier.

Two habits hold this together. Flag the press value as supposed rather than read, in whichever sentence spends it, since that quantity is what turns a tally of events into pounds and nothing published pins it down. And keep the payment and the winnings in separate columns from the first line, because the moment they are added the question of which pile a term sits over becomes unanswerable.

Run on this page’s own arrangement the method yields a short list and stops: £10.00 paid, £10.00 of stake committed, a middle outcome of £9.60, a rate of forty pounds of staking for each pound returned, and a surviving share of minus six tenths whatever happens. One of those is on the banner, one is in a second document, and the rest are consequences.

The conclusion that matters is the narrow one. A condition attached to winnings cannot be priced before the winnings exist, so a reader cannot know the size of what they are agreeing to however carefully they read. What they can establish in a glance is whether the condition expects to take more than the winnings hold, and on anything at or above twenty-five times it does.
