A code that spends one way, and the exit nobody built before the win

1

An instrument built to travel towards the reels and not away

One direction is the whole design. A prepaid code is bought over a counter with cash or with a card, carries a sixteen-figure string, and is spent by typing that string into a cashier. Nothing in the object points the other way. It has no account behind it to receive anything, no sort code, and no holder a payment could be addressed to, which is exactly why it can be bought by somebody who wants no account involved.

Nought is therefore the progress a reader has made towards being paid at the moment the money goes in. That is the premise of this note and it is worth separating from the complaints usually made about prepaid money. The charge here is not that the instrument is slow. It is that the instrument does not take part in the second half of the transaction at all, so the second half has to be assembled from scratch, by somebody who has already won and is now waiting.

Two quantities get priced below and neither of them is printed anywhere a buyer would see one. The first is the gap between what a code is sold in and what a balance is wanted in, which is money that goes in and does not come out as play. The second is the span between a request to be paid and money arriving, measured on a route that did not exist when the request was made.

Eighty-eight hours is the figure this note models for that span, built from four lengths set out in part five, every one of them an assumption of this page rather than a published timetable. Nothing here was clocked, and a reader who disputes one of the lengths should substitute their own and run the additions again. The additions are the page. The inputs are arguable, and wherever one of them turns up in a sentence, that sentence admits it.

Where a fixed step meets a balance that moves by the penny

Twelve pounds is what a reader wants showing in the account, and twelve pounds is a figure a code cannot deliver, because codes are sold in fixed steps and a balance is free to take any value at all. That mismatch is the first cost on this page and it falls before a single press. Everything in this part turns on the size of the step, and the sizes used below are assumptions of this note rather than a schedule taken from anywhere.

Two codes at an assumed step of ten pounds is the nearest a buyer can get to twelve, which means twenty pounds leaves a pocket to put twelve into play. Eight pounds is the difference, and the difference is not a fee, a charge or a margin. It is the reader’s own money, sitting in the reader’s own balance, arriving there because the only quantities available were the wrong ones.

Rounding up is forced in one direction only, which is what makes the arithmetic one-sided. A buyer who needs twelve cannot buy one and a fifth of a ten pound step. The general shape is a ceiling function: codes bought is the target divided by the step and rounded upward, paid out is that count multiplied by the step, and the stranded part is what is left when the target is taken off the payment.

Three hundred and sixteen point seven per cent is the worst row and it is the one nobody models, because a buyer reaching for a single large code is thinking about convenience rather than about the thirty-eight pounds they have just committed. The column of overshoots is not a scale of carelessness. It is a scale of how coarse the available quantities are against the quantity actually wanted.

Half the step is the average overshoot once the target is allowed to be anything, which is the useful general result and takes one line to see. A target landing anywhere inside a step is equally likely to need a penny of rounding or almost the whole step, so the mean of the two ends is the midpoint. An assumed step of ten pounds therefore strands five pounds on an average purchase, and an assumed step of twenty-five strands twelve pounds fifty.

One penny over a step is the shape of the worst purchase, and the shape turns up often enough to earn a line of its own. Somebody wanting £25.01 at an assumed twenty-five pound step buys fifty pounds and strands £24.99. The stranding is at its largest exactly where a reader thought they were being precise.

What the overshoot does for a living once it is inside

Eight pounds is the figure this note carries forward, taken from the ten pound step in the middle of the table. It is not lost and nobody has charged it. It is converted, from money a reader could spend on anything into money that can leave by one of two routes only, and both routes are priced on this page.

Eighty presses is the first route, since eight pounds at ten pence a press is eighty of them. Sixteen minutes is how long eighty presses occupy where each one is allowed twelve seconds, a length assumed by this site and produced by no stopwatch. Under three quarters of one sitting covers it, a sitting being the twenty-two minutes this site assumes for a go with a handset and likewise never measured.

£8.00 stranded by a step, which is 16 assumed minutes of reel

Thirty-two pence is what one pass of that eight pounds over the reels is expected to cost, since the return held fixed here hands 96p back for every pound staked. Spent that way the overshoot is not wasted so much as quietly converted into a little under a third of a pound of expected loss, plus sixteen assumed minutes of somebody’s evening, neither of which the buyer set out to purchase.

Withdrawal is the second route out, and the whole of this note stands on it. The eight pounds can be asked for back, and the instant it is asked for it joins the queue every other pound in the balance is in, because a balance does not remember which pounds arrived by overshoot. Asking for it back means producing a route out, and producing a route out is the subject of part four.

One consequence deserves stating plainly before the next part starts. The step that overshot at the entrance is the same step that cannot receive at the exit, so the instrument creates a remainder and then declines to take the remainder back. Those are not two separate complaints about prepaid money. They are one property of a one-way object, seen from each end.

Opening a route out after the win instead of before it

One hundred and twenty pounds is the balance this note follows from here, a figure chosen because it divides cleanly and because it is the size a reader of a page like this one would recognise. At ten pence a press it is 1,200 presses, four hours of pressing on the twelve seconds assumed here, and eleven sittings at the twenty-two minutes assumed for one. It is a real evening’s worth of outcome and it is sitting in a place with no door cut in it.

Twenty-six hours is the length this page puts on cutting that door: naming a bank account or a wallet, having the name on it matched against the name on the gambling account, and having whatever that receiving arrangement wants for its own records satisfied. The figure is an assumption of this page and nothing on it was observed. It is deliberately put below two days, because a reader who already holds a current account and simply has not told anybody about it is doing paperwork rather than opening anything.

Nought hours is the same step for a reader who named a receiving arrangement when they registered, and the nought is the entire argument of this part. The work does not get cheaper by being done early. It stops being in the way, which on a queue is the only thing that matters.

Forty-six hours is the gap between the two columns of that drawing, being twenty-six for the arrangement and twenty for a check that could have happened months earlier. Just under two days of a reader’s life is the price of having paid in with something that cannot be paid back into, and the price is not charged in money anywhere a buyer could see it.

Matching the name is where the twenty-six hours most often goes long, and it is the step a reader can do least about once they are standing in it. A payment leaving a gambling account is expected to arrive at an account in the same name, which is reasonable, and it is also a check that cannot be done in advance by somebody who has not yet said which account they mean. A reader who named one at registration had that comparison made while nobody was waiting for the money.

Nothing in this part is an argument for skipping a check, and the distinction matters. The check is not the problem. The position of the check in the queue is the problem, and moving it costs nobody anything, which is the finding this section hands to part five.

Four pieces of one wait, weighted for a code payment

Four lengths make up every wait on this subject and they are worth separating, because they belong to different parties and respond to different things. A desk decides how long it looks at the request. A desk also decides when the identity work happens. The machinery that moves money decides the clearing leg. The calendar decides the rest, and answers to nobody.

Twenty point five per cent is the share belonging to the only part most readers think about, which is the money actually moving. Four fifths of the modelled wait is therefore decided before a transfer is even instructed, and none of that four fifths is a property of any payment network. It is a property of how a desk sequences its own work.

Fifty-two point three per cent is the share carried by the two pieces that exist only because the way in cannot be the way out, being forty-six hours of the eighty-eight. Over half the modelled wait is attributable to the choice of instrument at the entrance, months before anybody thought about an exit.

Reordering is what the right-hand column represents and it is the cheapest change on this page. Nothing in it is faster. The same checking happens, the same arrangement gets named, the same comparison of names is made. All that differs is that the work sits before the request rather than inside it, which takes the modelled wait from 88 hours to 42 and leaves the total labour untouched.

One warning belongs with the table. A reader who deposits by code and names a bank account at registration anyway has the right-hand column, and this page is not arguing otherwise. What the left-hand column sets out is the usual case. The instrument was picked to keep a bank out of the transaction, so no bank was ever named, so nothing is on file to pay into when the moment arrives.

Shut days, counted against a Friday evening and a Monday morning

One hundred and twenty hours out of every 168 is what this note treats as open for the leg where money actually moves between accounts, running from midnight on Monday to midnight on Saturday. That is an assumption of this page, adopted to make the arithmetic visible, and it is not a timetable published by anybody. Seventy-one point four per cent of the week is open on it, and the other forty-eight hours are not.

Monday at nine in the morning is the easy case and it is worth doing first. The hold finishes Tuesday at nine, the identity work finishes Wednesday at five in the morning, the receiving arrangement is ready Thursday at seven, and eighteen hours of clearing finishes at one on Friday morning. Eighty-eight hours, with nothing inserted, because every piece fell inside the open part of the week.

Friday at six in the evening is the awkward case and it produces a result nobody expects. The hold runs to Saturday at six, the identity work to Sunday at two in the afternoon, the receiving arrangement to Monday at four, and the clearing leg to Tuesday at ten in the morning. Eighty-eight hours again, and not a minute of shut calendar added, because the shut part of the week was entirely consumed by work that does not need a bank to be open.

104 shut days in a 365 day year, which is 28.5 per cent of it

Seventy-two hours is what the same Friday evening produces on the other column, and that is where the surprise sits. A reader who named a receiving arrangement early finishes the hold at Saturday six in the evening and then waits thirty hours for the machinery to open on Monday, clearing at six on Monday evening. The early-naming advantage falls from forty-six hours to sixteen, not because the code route improved, but because the quick route spent the weekend standing still.

One hundred and four days of a 365 day year fall on a Saturday or a Sunday, which is 28.5 per cent of the calendar, and public holidays add to that by an amount this page does not fix. A wait that crosses a weekend is therefore not an unlucky wait. It is the statistically ordinary one, and any figure quoted for a payout that does not say which day of the week it assumes has left out roughly three days in ten.

Nought is the amount of this a desk controls, and that is the honest half of the paragraph. Nobody at a cashier can open a bank. What a desk can control is when it starts, and a request released at four on a Friday afternoon rather than at eight that evening lands in a different week entirely for the purpose of the leg that follows.

Where a balance sits while a way out is still being built

Eighty-eight hours is a long time for £120.00 to be somewhere a reader cannot reach, and the sensible question is where exactly it is. Offshore is where an arrangement like this one is run, holding no Great Britain licence, so the duty worth putting beside an eighty-eight hour wait is the one that makes a desk say where customer money sits.

A British licensee has to tell the people whose money it holds where that money sits, what becomes of it should the business fail, and which rating the arrangement earns. Twice a year is what licence condition 4.2.1 attaches to the telling where the rating disclosed is the unprotected one, which makes it the only interval on this page fixed by a rule rather than by this note. That interval binds from 31 October 2025, the date a single consultation response also gave to the amended wording on financial limits.

Nought such notice is owed by a desk outside the register, and the gap is sharpest exactly during the eighty-eight hours this page has been modelling. A balance that cannot be reached is a balance whose safety a reader is taking on trust, and the British rule does not make the money safe either. It makes the arrangement disclosed, and then makes the disclosure repeat so that nobody forgets what they agreed to.

Forty-eight hours is what a cap of that shape would add to the balance this page is following, and the addition is in holds rather than in money. A £120.00 balance against an assumed fifty pound daily ceiling cannot leave in one request. It leaves in three, on three separate days, and each of the three is read by the desk afresh, so the twenty-four hour hold assumed here is paid three times over instead of once.

Seventy-two hours of hold against twenty-four is the arithmetic in full, and it shows a rule written in pounds arriving at a reader as a rule about days. The capped reader is not refused anything. They are simply put through the slowest piece of the chain twice more than they needed to be, and the cap is printed as a figure in pounds where the cost is paid in days.

One further loss belongs here and it is specific to the instrument. A reader who paid in with a code and is then asked to supply a bank account has lost the privacy the code was bought for, and lost it while a balance sits on the far side of an unanswered request. Outside the British licence there is no condition obliging anybody to have told them, at the counter, that this was coming.

Who the code suits going in, and whom it strands coming out

One reader is genuinely well served and should be named before anything else. Somebody who wants a fixed amount in play, no card number typed anywhere, and no balance left behind has bought precisely the right object. A code spends what it is worth and then it is finished, which is a real limit built into a real thing rather than a setting that can be changed at eleven at night.

Eight pounds is what that reader still pays for the privilege at an assumed ten pound step, and the honest framing is that it is the price of the limit rather than a defect in it. Sixteen assumed minutes of reel is what the eight pounds buys if it is played off, and nothing at all if it is left standing, because a balance left standing is a balance that has to be withdrawn, and withdrawing is the expensive part.

Eighty-eight hours against forty-two is the comparison for everybody else, both modelled here on assumptions this page states rather than on anything measured. The second figure is not a different payment network. It is the same chain with two pieces of it moved to a moment when nobody was waiting, and any reader can have it by naming a receiving arrangement on the day they register, before a press is made.

Three questions settle it, and the advertised wording answers none of them. Whether anything can be paid back to the instrument that was paid in with, which for a prepaid code is usually not. What the step is, since half of it is the average stranding. And what the desk wants before it will release money, since the pieces a reader can move early are worth forty-six of the eighty-eight modelled hours here.

Nought of this makes the arithmetic of the reels better. A £120.00 balance reached through a condition at forty times would have cost 160 pence of expectation for every hundred credited, and no payment instrument repairs that. What the instrument decides is the last stretch, after the pressing has stopped, when the only question left is how long somebody waits for an answer about their own money.
