One pound in, one pound credited

The simplest match there is doubles what a reader hands over. Pay in a pound, hold two. Nothing in that sentence is false and nothing in it is a sum of money either, because a percentage has no value until somebody supplies the number it multiplies.

So this sheet supplies one. Ten pounds goes to the cashier, ten pounds of bonus credit appears beside it, and the balance reads £20.00. Half of that was yours before you started.

Keeping the halves separate is the whole discipline of this section. The tenner moved address and did not change owner. The £10.00 of credit is an entry that turns into money only if a turnover condition is met, and may turn into nothing instead. Adding the two and calling the total twenty pounds of value counts the reader’s own wallet as part of the offer.

A doubled headline is the useful place to start on a sheet like this, because it is the plainest case and because it sets a unit. Everything that follows is measured per pound paid in, which makes a hundred per cent, two hundred, three hundred and four hundred directly comparable without any arithmetic beyond multiplication.

Forty pence, and where it comes from

Strip the offer down to a single pound and the entire page fits in three lines.

One pound paid in buys one pound of credit. Turned over forty times, that pound of credit demands £40.00 across the reels, on which the edge expects £1.60. The account holds £2.00, so forty pence is the residue.

Forty pence per pound paid in. On a tenner, £4.00. On fifty pounds, £20.00. Nothing about that ratio shifts when the payment does, and that is precisely what makes it a unit instead of a result.

Two observations follow, and both of them are uncomfortable.

The first is that forty pence is a loss. A reader who never claimed the offer still holds their pound. Claiming it and clearing the condition is expected to leave forty pence of it, so the match costs sixty pence of the reader’s own money for every pound they put through it. The headline is a hundred per cent and the expected transfer runs the other way.

The second is that the forty pence falls as the percentage rises. Two pounds of credit per pound paid in generates £1.20 of overrun against £1.00 of stake, which is twenty pence underwater. Three pounds generates £1.80, which is eighty pence underwater. The whole family of percentage headlines sits on one straight line, and a matched pound is the only point on it with anything left over.

The expression, run on a tenner

Reasoning per pound is quick, and the long form earns one outing, so this sheet’s arithmetic now takes the matched tenner entire.

E = B × (1 – (W × (1 – RTP)) / g)

Everything on the right of it is known before a single cycle is played. The face of the credit is B, £10.00. The turnovers demanded are W, forty of them. The proportion the game gives back is RTP, 0.96. The weighting is g, one here. And E is the credit’s worth once the condition has been discharged.

Put it in pounds. Forty turnovers of £10.00 sends £400.00 across the reels, the edge takes four pence of each of those pounds, and the bill is £16.00. That is six pounds beyond the credit it was fastened to.

A negative E on a no-deposit offer stops at nothing, because nothing of the reader’s is exposed. A matched offer has somewhere for the excess to go. The account holds £20.00, the cost is £16.00, and the foot reads £4.00. Six pounds of a tenner has been spent buying the right to keep four.

Time comes out of the same figure. At 10p a cycle, £400.00 is 4,000 cycles, and a British slot cannot run them faster than one every 2.5 seconds, putting a floor of 10,000 seconds under the lot. Just under two and three quarter hours, in cycles that have to be committed to individually because RTS 8A keeps autoplay off the table.

Ten times to fifty, the whole range

W is the term that varies most between one set of terms and another, so the matched tenner gets priced at seven of its values. Credit holds at £10.00 throughout, the game returns 96 per cent, and weighting stays at one.

Two multiples on that schedule do something worth naming.

Twenty-five times puts the foot at exactly the tenner that went in, the credit having bought its own condition and added nothing at all. These particular pence have nothing to do with it. Solve the expression for E of nothing and W comes out as the reciprocal of the house edge: twenty-five on a 96 per cent game, twenty on a 95, and 33.3 on a 97. Any match at any percentage breaks even in the same place.

At fifty times the foot reads nothing at all. A doubled headline survives up to fifty because it only has one pound of credit per pound of stake to pay for, which is the mirror of the result on heavier headlines: a tripled match dies at 33.3 times and a quadrupled one at thirty. The bigger the number on the front, the earlier the multiple kills it.

The word and, priced

One conjunction in a set of bonus terms is worth more than any percentage on the front of the advertisement, and it is routinely skimmed.

Where the turnover is demanded on the credit alone, a matched tenner owes £400.00. Where it is demanded on the deposit and the bonus, the base is £20.00 rather than £10.00, the turnover is £800.00, and the expected cost is £32.00 against the same £20.00 in the account. The foot reads nothing and the condition is still twelve pounds from being satisfied.

Read the middle row against the bottom one. A doubled headline whose requirement reaches the deposit is a worse instrument than a tripled headline whose requirement does not. The percentage on the front went up by two hundred points and the outcome improved, because the base the multiple bites on matters more than the size of the gift.

Nowhere public has it been settled how the British ceiling handles that wording. Bonus funds is the phrase the ten-times limit uses, and nothing the regulator has put out works through a requirement reaching a player’s own balance as well. So the chain of published wording gets stated here and the page stops there.

A limit caps the match as well

Anything that caps a deposit caps everything downstream of it, because a percentage match is a multiple of the deposit and the turnover is a multiple of the match. One number at the top governs three below it.

Financial limits have to be available on a British system from the moment of registration. A prompt to set one comes either inside the registration process or at a first payment. Setting a limit is the default choice, so declining it takes a positive act by the customer. A day, a week and a month are among the durations that must be offered. Lowering a limit happens at once. Raising one waits a cooling-off period of twenty-four hours and then has to be confirmed a second time.

Where two limits overlap, the regulator publishes a worked case that drops straight into this page. A daily cap of £10 alongside a weekly cap of £100 resolves to the tighter of the two at every moment, so what the system may allow is £10 in a day and £70 in a week. Matched at a hundred per cent, that is £70.00 of credit in a week, £2,800.00 of turnover at forty times, £112.00 of expected cost and a foot reading £28.00 against £140.00 held.

Curaçao handles the two directions differently again, and on this one point it is the harder of the two regimes. Lowering a limit there is immediate as well. Raising one sits out seven days before implementation, against twenty-four hours in Great Britain. That runs against what a reader would expect, which is exactly why it is worth printing.

Method, not amount, is capped as well. Borrowed money cannot fund gambling on a British site: licence condition 6.1.2 shuts out payment by credit card, shuts out the same payment routed through a money service business, and has done so from 14 April 2020. A matched deposit there comes from money a reader already has. The Curaçao policy read for this sheet leaves that door open.

What a licence adds to a matched pound

The arithmetic on this page is indifferent to geography. The obligations underneath it are not, and a matched headline of this sort comes with no Great Britain licence behind it. Each missing duty is given below in pounds on the same tenner.

Ten rather than forty

Since 19 January 2026 a British wagering requirement has stopped at ten times bonus funds. On £10.00 of credit that is £100.00 of turnover, £4.00 of expected cost and a foot reading £16.00. Out here the same headline reads £4.00. The ceiling is worth twelve pounds on a tenner, and it is the single largest term on the page.

Checks that follow the money in

Light-touch financial vulnerability checks apply to a British online customer above a monthly net deposit threshold. That threshold started at £500 a month on 30 August 2024 and came down to £150 a month on 28 February 2025. Separate enhanced assessments remain a pilot rather than a live requirement, and the regulator states that neither affects a consumer’s credit rating. Matched at a hundred per cent, £150 of deposits in a month carries £150 of credit and £6,000.00 of turnover at forty times, which is 60,000 cycles at 10p.

What the rulebook offshore leaves out

The Curaçao responsible gaming policy of 21 February 2025 lists what an operator must do: verify age, make information accessible, offer self-assessment, track behaviour, allow cooling-off and self-exclusion, offer deposit limits, train staff and affiliates, and advertise responsibly. Read it twice and five things are still absent: any ceiling on a wagering multiple, any stake limit, any minimum interval between cycles, any bar on autoplay, and any objection to a game throwing a fanfare over a return no better than the stake.

Affiliates are reached there directly, where the British regulator’s own advertising page does not reach them. An operator there is made responsible for affiliate compliance through binding contracts, audits and penalties. That is one place the offshore rulebook is more explicit, and it is worth recording honestly on a page that exists to be found through advertising.

Self-exclusion, from one place or many

Holding a British licence puts an operator inside Gamstop Online whether it fancies the idea or not, and the scheme states the edge of its reach without dressing it up: where an organisation has not joined, it cannot keep a registered person away. Offshore the unit is the operator rather than the market. A Curaçao exclusion covers one licensee and the domains it runs, and that policy’s answer to everywhere else is that the player should be encouraged to exclude themselves there too.

Pricing a match of your own

Five steps, and the last two are where a reader learns something.

The shortcut, for anyone comparing offers in a hurry, is to multiply the percentage by the multiple and read the answer as turnover per pound. One hundred per cent at forty times is forty pounds per pound. Two hundred at twenty times is also forty pounds per pound, and the two offers are identical in everything but how they are advertised.

Two cautions before anybody spends it.

What the foot gives is an average across many repetitions, never a forecast of one. Four pounds is the long-run worth of a matched tenner, while the commonest result of a single attempt is an empty balance long before the turnover has been met.

And a term beats a figure every time. Five things come off the cashier’s own document rather than this one: W, g, the base the requirement bites on, whatever lid is put on the credit’s winnings, and how long the window runs.

Neighbouring headlines are priced the same way on 200% deposit bonus, the first of the family to stop leaving anything, 400% deposit bonus, the largest and the worst of them, and deposit 10 get 100 free spins, which is roughly this page’s offer paid in spins instead of cash. The index at Matched money lists the rest.
