100 free welcome bonus, no deposit required: a hundred of what?

A hundred of what

This is the page where the premise of the whole site is doing its most obvious work. A number without a unit is not a quantity. It is a shape that looks like one.

Two readings fit the words. On the first, a hundred means a hundred presses of a slot, and the unit is the price of one press. On the second, a hundred means a hundred pounds of bonus credit, and the unit is the pound. Both readings are common in this market, both are consistent with the words “no deposit required”, and they are worth entirely different amounts.

A third reading is excluded by those same words, and section five deals with it, because a great many offers advertising a hundred are advertising a hundred per cent of something a reader has to pay in first. Where nothing is paid in there is nothing to take a percentage of, so a percentage reading cannot survive the phrase.

What follows prices the two surviving readings separately, then sets them side by side, then asks what the advertising rules have to say about a headline that leaves the unit out. The answer to the last question turns out to be more useful than a reader might expect.

Reading one: a hundred presses

Take the count reading first because it is the simpler sum. A hundred presses at ten pence is £10.00 of staking. Where the return runs at 96 per cent the expected amount coming back is £9.60, with the machine retaining forty pence.

Nothing further is deducted unless the terms say so, and that is the structural feature of a count. The presses are already paid for, so there is no balance for a play-through to attach itself to. Where a requirement lands on the winnings instead, it scales the £9.60 rather than the £10.00.

Duration is the figure the headline omits. Game cycles on a licensed slot sit two and a half seconds apart at the closest, which floors a hundred presses at four minutes and ten seconds. Each press needs its own commitment, there being no turbo and no slam stop to be had and autoplay prohibited across gaming.

Reading two: a hundred pounds of credit

The cash reading starts ten times higher and then has a condition fastened to it, which is the reason the two readings do not simply differ by a factor of ten at the foot.

A hundred pounds of bonus credit buys a thousand presses at ten pence apiece. Being a balance, though, it is the sort of thing a wagering requirement fastens onto, and the arithmetic there scales: take the credit, subtract from one the multiple times four per cent, and multiply. Fourpence in the pound is the house’s share where the return runs at 96 per cent.

The time column is the part of this table nobody prints, and at this size it stops being a detail. Ten thousand presses approach seven hours of button work where a licensed slot runs them at its permitted maximum, and forty thousand exceed a day. A hundred pound credit at a fortyfold requirement is not a generous offer with a catch. It is a job.

Two of those rows are unavailable on a British licence, and the limit is the single most valuable protection on this page. A play-through above ten times cannot be put on bonus funds, a rule holding since 19 January 2026, and before the ceiling arrived practice had reached sixty times. So the tenfold row is the floor of this market, the twentyfold and fortyfold rows describe cashiers the limit does not reach, and the twenty-five times row is where any credit of any size reaches nothing at all.

A maximum bet clause usually rides alongside, and it fixes the rate at which the staking may be done. Take a cap set at a tenth of the credit or at five pounds, whichever of the two is lower: a hundred pound credit is then held to five pounds on one bet. Two hundred bets at least are needed to put a thousand pounds through, and ten thousand presses at 10p each.

The two readings side by side

Now put them in one frame, which is the comparison a reader actually needs and which no advertisement will do for them.

The ratio row is the finding. In whichever column a reader looks, the cash reading comes out at roughly ten times the count reading, for the plain reason that a hundred pounds is ten tens. The conditions do not change the ratio because they scale both readings by the same proportion.

So the unit is worth a factor of ten, and the multiple is worth a factor of less than two between nothing and the regulated ceiling. A reader who spends their attention on the wagering line and skips the unit has read the small number and missed the large one. That is the most useful sentence on this sheet.

One asymmetry does separate the readings and it is worth stating. The count reading has its expectation fixed by the count: a hundred presses at 10p cannot be worth more than £10.00 however the session goes, in expectation. The cash reading has its expectation fixed by the credit, and the credit is a balance that can be lost in full before any requirement is met. On the tenfold row the credit is expected to leave £60.00. On the twenty-five times row it is expected to leave nothing, and that nothing is an average over sessions where the balance has gone early as well as sessions where it has survived.

The unit is worth ten to one; the multiple, between nothing and the ceiling, is worth less than two to one

The reading the words rule out

A third reading has to be dealt with because it is the commonest shape in this market, and the phrase “no deposit required” is precisely what excludes it.

A hundred per cent welcome bonus is a match. It doubles whatever the reader pays in, so it produces a bonus equal to the deposit and a total balance of twice it. No deposit means no match, because a percentage of nothing is nothing, and a reader who meets a hundred alongside the words “no deposit required” is not being offered a match whatever else they are being offered.

The match arithmetic is worth setting out anyway, because it answers a question readers ask of every percentage they meet. What the regulated ceiling binds is the multiple rather than the percentage, so turnover per pound of bonus does not climb when the percentage does. It raises the bonus, and the total turnover rises in the same proportion.

The ratio is ten to one in every row, so the bigger headline is a bigger obligation in exactly the same proportion as it is a bigger bonus. The ten is the regulated ceiling and the rest of the table is this site’s own arithmetic. That weighting note in the fourth row is a reminder and not a figure about anybody’s offer. A game counting below its face towards a requirement pushes the staking up while leaving the printed multiple untouched.

One more thing separates a match from either reading on this page. On a match the reader’s own deposit is in the account and is not part of the bonus, so the two have to be shown in separate columns. An award needing no deposit has no second column whatever, and that is the single respect in which it prices more simply than anything else here.

What the rules say about a number with no unit

A headline that omits the unit is an advertising question before it is an arithmetic one, and the published rules on this are more direct than readers tend to assume.

One short duty underpins the rest: a marketing communication must not mislead the consumer reading it. Significant conditions then need prominence within the advertisement, and a position near the headline offer on whichever landing and sign-up pages are relevant. What follows from failing that is spelled out by the regulator: insufficient prominence for those conditions means the advertisement will be seen as a misleading one.

Which codes apply is published too, and the list is longer than the gambling section alone. On the non-broadcast side, four sections of the advertising code are named: misleading advertising, promotional marketing, gambling and lotteries. On the broadcast side there are four as well: misleading advertising, gambling, lotteries and premium-rate telephone services. Beneath all that sit two code provisions of the licence: compliance with the advertising codes is the subject of one, and consent for direct electronic marketing the subject of the other.

Two further rules bear on how a headline of this kind may be framed. Marketing must not suggest that gambling can be a solution to financial concerns, nor an alternative to employment, nor a way of achieving financial security. Nor may it be likely to appeal strongly to a child or a young person, and nor may it carry a person or a character whose example somebody under eighteen is likely to follow.

What the regulator will not supply is any definition of the unit. Three things go unaddressed by every published source: the worth of a free press, the identity of whoever settles that worth, and whether anybody owes a disclosure about it. So nothing in the rules forces an advertisement to settle the ambiguity this page deals in. The duty is not to mislead, and whether a particular headline misleads is a question for a ruling rather than for a formula.

Rulings do exist, and three recent ones are listed on the regulator’s own page about online casinos, with their outcomes and nothing more. One against HRY Games was upheld, dated 14 October 2026. One against Dribble Media Ltd was upheld, dated 16 September 2026. One involving White Hat Gaming Ltd was not upheld, also dated 16 September 2026. Nothing on the page describes the subject matter of any of the three, so naming them as recent rulings about casino advertising is as far as this sheet will go.

The conditions that bite under either reading

Three conditions apply whichever unit the hundred turns out to be, and each of them lands in a different place depending on the reading, which is a useful way to see what they do.

Start with the ceiling. At 9.6p of expectation per press, a ceiling divided by 9.6p names the count beyond which it is the ceiling and not the count doing the deciding. A ten pound ceiling is reached at 104 presses. On the count reading, where the award is a hundred presses, a ten pound ceiling therefore sits four presses above the whole offer and barely binds. On the cash reading, where the credit buys a thousand presses, the same ten pound ceiling removes at least £50.00 of the £60.00 the tenfold row produced. One figure, two entirely different effects.

Then the floor. Ten pounds as a smallest withdrawal asks 1.04 times the mean of the count reading, which an ordinary session sometimes supplies, and asks nothing whatever of the cash reading, sixty pounds standing well clear of it. A floor is a condition that hurts small awards and ignores large ones, which is the opposite of the way a ceiling behaves.

Then the clock. A hundred presses need four minutes and ten seconds. Ten thousand presses, which is what clearing a tenfold requirement on a hundred pound credit takes, need six hours and fifty-seven minutes. Put a seven-day window around the second of those and it is just under an hour a day, every day, for a week. Put a twenty-four hour window around it and it cannot be finished by anybody with a job.

Two statements about the ceilings in that table. Those removal figures bound the loss from below instead of measuring it, since a ceiling works on individual outcomes and not on an average, and how a slot spreads its return is set out nowhere in print. Nor is there a primary source carrying a standard figure for a bonus win’s maximum, which leaves those ceilings as round numbers picked for legibility.

In pence, what the licence is worth here

Wording like this one’s is common out at the offshore end, where no Great Britain licence stands behind the offer. Because this page is about units, the comparison belongs in units too, so here it is in pence and in pounds rather than in principles.

On the multiple: the British ceiling is tenfold, so the worst a licensed cashier may do to a hundred pound credit is leave £60.00 of it. Offshore, nothing in the Curaçao responsible gaming policy caps a multiple at all, so the twenty-five times row is available, and that row leaves nothing from a credit of any size.

On the stake: one cycle of an online slot here has a five pound cap, which drops to two pounds for a customer beneath twenty-five, and the two figures carry 9 April 2025 and 21 May 2025 in the regulator’s guidance. In presses at 10p, five pounds is fifty presses in one cycle. No stake figure of any kind appears in the offshore policy read for this sheet.

On the clock: no slot here runs a cycle more often than every two and a half seconds, and that is what puts six hours and fifty-seven minutes beneath ten thousand presses. Offshore, no minimum interval appears, and nothing addresses turbo or a slam stop, so the same ten thousand presses could be run in a fraction of the time, which is a change in exposure rather than in expectation.

On the exit: a British licence puts the operator into the national online self-exclusion scheme, and one registration closes every licensed account. The scheme, which renamed itself Gamstop Online in November 2025 and writes its own name with a lowercase s in the middle, states its own boundary plainly: its help reaches the participating operators and stops there. Out there an exclusion gets arranged with a single operator at a time.

On the advertising: the British codes run to four non-broadcast sections and four more for broadcast, with prominence of significant conditions and the consequence of getting it wrong published in terms. Marketing restrictions of its own do appear in the Curaçao policy, and they are far from trivial. Advertising that misleads is barred, as is advertising that is excessive or aggressive. Targeting the self-excluded is barred, and so is targeting anybody with a gambling problem or in financial difficulty. Presenting gambling as a route to financial success is barred. Misrepresenting skill against chance is barred too, and emotional manipulation with it, and content built to appeal to children, and any marketing sent while a cooling-off period is running. What it does not do is set out what a significant condition is or where it has to appear.

On tax: nothing changes and a reader saves nothing. Where a player usually lives is what gaming duty attaches to, not the jurisdiction standing behind a licence, which brings any operator taking British play inside its scope. Three things go with the licence itself. Eight weeks as the span inside which a complaint must finish. The adjudicator, approved to hear it next. The register able to shut every licensed account at a stroke.
