The anatomy of a welcome offer: five lines on a price list

Read every welcome offer as a quote for work to be done, because that is what the terms actually price. Five lines carry nearly all of the money information: the match rate, the cap, the wagering requirement, the expiry clock and the maximum stake. The advertising shows the first line and stops there, and the first line is the cheapest of the five to honour. Everything that decides whether a bonus ever reaches your bank account lives on the other four, and none of them appear in the banner.

The match rate is the multiple a cashier applies to your first deposit. A 100% match doubles it, a 200% match triples it, and the 400% bracket at the top of this market quadruples it. The licensed British bracket tends to print 100% matches with ceilings between £50 and £300. The offshore bracket this page models runs wider: 100% to 300% is the working range, a 250% stop appears in places, and headline ceilings sit around £/€1,000 to £/€2,000. The percentage is the line readers quote to each other, and it is also the line that tells you least.

The cap is the ceiling the bonus stops at, whatever the match implies. Divide the cap by the match and you get the deposit at which the percentage stops working: a £250 cap over a 300% match is about £83, so a £90 deposit and a £400 deposit both earn the same £250. Past that threshold the match rate is decoration. Caps are the quiet reason a bigger percentage is not always a bigger bonus, and the offshore bracket leans on them harder than the licensed one, because headline percentages there are larger to begin with.

The wagering requirement is the bill. Multipliers between 30× and 45× are the norm at both ends of the market, with 35× the common middle. The multiplier alone is half a number: it needs a base. Applied to bonus funds only, 35× on a £50 bonus is £1,750 of stakes. Applied to deposit plus bonus, the same terms price at £3,500. Two offers can print identical 35× lines and differ by a factor of two in cost, which is why the words after the multiplier deserve more attention than the multiplier itself.

The expiry clock converts the bill into a daily rate. Terms at a typical cashier count the window in days rather than weeks, so take seven days as the model input, because short clocks are the norm in this part of the market. £1,750 of wagering inside seven days is £250 staked per day; £3,500 is £500 per day. Miss the clock and unplayed bonus funds and unfinished wagering usually disappear together, taking any winnings tagged to the bonus with them.

The maximum stake line is the smallest print with the largest teeth. While wagering is live, this end of the market usually caps a single bet at about £5, and the rule bites harder than its size suggests: one bet above the ceiling can void the bonus and everything won with it, and the limit normally applies across the whole requirement rather than to bonus-funded stakes alone. It also caps clearing speed, which matters once the expiry clock is running.

The lines also interact, which is why reading them one at a time is only the first pass. A long expiry softens a large wagering bill; a low maximum stake hardens it; a generous match with a tight cap behaves like a small match above the threshold deposit. Pricing an offer is arithmetic on five variables, and the arithmetic is the whole service this page performs: the numbers are knowable before you deposit, which is more than can be said for most of what the banner promises.

Read the five lines in order and a welcome offer stops being a headline and becomes a price. The match sets the size, the cap sets the true ceiling, the wagering sets the bill, the expiry sets the daily rate and the maximum stake sets the pace limit. The rest of this page prices each line in turn, then hands you the calculator to run your own deposit through the same arithmetic.

What a match rate is worth per £100 deposited

Face value and usable value are different numbers. Face value is the bonus the cashier prints; usable value is what survives the wagering bill. The gap between them is where most of the disappointment in this market lives, so this section measures it directly. The model takes a £100 deposit, applies each match rate, requires 35 times the bonus on bonus funds, assumes the stakes run through online slots at a 96% return-to-player, charges the expected cost of that staking against the bonus and ignores caps, so the caps get their own treatment below.

On those assumptions the model lands near £62 of usable value for every £100 deposited at a 100% match, near £71 at 200% and near £78 at 300%. The pattern matters more than the decimals. Each rung up the match ladder adds less than the rung before it, because the staking bill grows in proportion to the bonus while the deposit, which anchors the per-£100 figure, stays fixed at £100. A second 100% of match adds another £100 of bonus and a proportionally larger bill, so most of the added face value goes straight back into clearing the requirement.

The chart below shows the three modelled points on one axis, pounds of usable value per £100 deposited.

Caps trim the top of these curves first. Take the 300% match with a £250 cap from the calculator settings on this page. The percentage works at full strength until the deposit passes about £83; past that point the bonus sticks at £250 whatever you deposit. At a £200 deposit, face value per £100 deposited has fallen from £300 at the threshold to £125, and the wagering bill on the capped £250 at 35 times is £8,750 either way. Usable value falls faster than face value, because the bill is fixed while the bonus is not. The chart is drawn before caps precisely so the cap arithmetic has room to show itself here.

Deposit size moves the same arithmetic from the other direction. The chart fixes the deposit at £100 to make the bars comparable; change the deposit and the cap decides whether the bars move at all. Below the cap threshold, usable value scales roughly with the deposit, so a £50 deposit at 100% is a smaller copy of the £100 bar. Above it, extra deposits buy nothing: a £300 deposit under a £250 cap at 300% earns the same bonus as a £90 deposit, and every pound past the threshold dilutes the per-£100 figure. Readers at the top of the market are diluting fastest, which is the quiet trade behind the biggest percentages.

A note on how to argue with the model, because arguing with assumptions is the correct response to any chart in this market. The two dials that matter are the return-to-player and the multiplier: lower the return and every bar sags, raise the multiplier and the sag steepens, while the ordering of the three bars survives both changes. Treat the figures as a central estimate produced under stated settings, and treat anyone quoting a welcome offer without settings as someone quoting a price without the goods.

One more caveat belongs next to the chart: the model prices bonus funds only. Where terms apply the multiplier to deposit plus bonus, every figure on the chart moves down, and the 300% bar moves most because its bill is largest. The next section prices that difference deposit by deposit.

The doubling trap: bonus-only wagering against deposit plus bonus

Two conventions share the same vocabulary. Some terms apply the multiplier to bonus funds only; others apply it to deposit plus bonus, and the second convention doubles the bill without changing a single printed number. Because the multiplier is the figure everyone quotes, the base is the detail that decides whether a 35× offer costs one evening or one week. This section prices the difference at three deposit sizes, using a 100% match, so the bonus always equals the deposit and the only variable is the base.

The table below is the whole argument in five columns.

Read the last column first: at every deposit size, the deposit-plus-bonus base doubles the stakes owed. On a £50 deposit the choice of convention is the difference between £1,750 and £3,500 of qualifying staking. On £100 it is the difference between £3,500 and £7,000. Nothing else in the terms changed: same deposit, same match, same multiplier. The base is worth a second multiplier all by itself, which is why this page keeps calling it a trap rather than a technicality.

Time turns the difference into something you can feel. At £2 a stake and eight seconds a spin, £1,750 is about 875 spins, close to two hours of continuous play; £3,500 is about 1,750 spins and twice that. Against a seven-day expiry clock, the first base asks for £250 staked a day and the second asks for £500. Game weighting multiplies both figures again, and the maximum stake rule caps how fast any of it can be cleared. The doubling trap is not an accounting curiosity; it is the difference between an offer that fits a week and one that does not.

The cap adds a second twist to the trap. Because the bill scales with the base while the cap limits only the bonus, a deposit-plus-bonus offer with a tight cap can price worse per pound of bonus than a bonus-only offer with the same multiplier. £100 deposited at 300% under a £250 cap earns a £250 bonus; the bill is £8,750 on bonus-only and £12,250 on deposit plus bonus. The bonus is identical in both readings; the bill is not, because the deposit is real money in the second base and the terms charge for clearing it too.

Comparing offers without checking the base is the mistake this section exists to prevent. A 40× bonus-only offer and a 35× deposit-plus-bonus offer look almost identical in the headline and differ by more than a fifth in real staking: 35 times 2 is 70 times the deposit, against 40 times 1, which is 40. The second offer is 75% more expensive despite printing the smaller multiplier. Whenever two offers are being compared, normalise them to stakes per pound deposited before anything else.

The two conventions hide behind similar sentences. Bonus-only terms say the wagering requirement applies to the bonus funds, or that the bonus must be turned over thirty-five times. Deposit-plus-bonus terms say the deposit and bonus are subject to wagering, or that the total amount must be staked before withdrawal. If the sentence names only the bonus, the bill is the smaller one; if it names both, double it. When the terms are silent, treat the larger base as the working assumption, because hoping for the cheaper reading is not a pricing method.

Game weighting: when a pound staked is not a pound counted

Weighting decides how much of each stake counts towards the wagering total. A pound on a slot usually counts as a pound; a pound on a table game often counts as ten pence; a pound on a live dealer table frequently counts as nothing. The multipliers and bases from the previous sections assume a 100% weighting, which is the slots assumption, and the moment you play anything else the effective bill changes. Weighting is where welcome offers do their quietest repricing.

The table below collects the category-typical weightings this site uses when it models offers at this end of the market.

The consequences compound quickly. Take the £50 bonus at 35× from earlier sections: £1,750 of qualifying stakes. Cleared entirely on slots, that is £1,750 actually staked. Cleared on a 10% table weighting, the same progress needs £17,500 staked at the tables, ten times the action for the same credit. Cleared at a live table with a 0% weighting, no amount of play moves the counter at all. A player who enjoys roulette and takes a slots-shaped bonus has bought a product that does not fit, and the terms will not refund the mismatch.

Bingo products deserve their own line on a site with bingo in the name. Bingo bonuses tend to run lighter requirements than casino bonuses, with single-digit multiples common where games carry 40× and up, but the categories rarely share one wagering pot: a bingo bonus at single-digit multiples and a games bonus at 40× can sit in the same welcome package, each with its own clock and its own weighting. Read the package as two offers wearing one badge, and price the casino half with this page’s arithmetic while treating the bingo half as the cheaper, lighter twin it usually is.

Three reading habits prevent most weighting surprises. First, find the contribution table in the terms before depositing; it is usually a short list of percentages beside game categories. Second, check whether named titles are excluded entirely, because some terms freeze specific slots out of wagering altogether. Third, assume the 100% line applies to fewer games than you expect: instant wins, scratch cards and bingo-side games each carry their own line, and the generous percentage usually travels with the products the operator wants played. The weighting table, the multiplier and the base together form the true price; any one of them alone is marketing.

Weighting also interacts with the doubling trap in one direction only. A deposit-plus-bonus base doubles the bill and then weighting multiplies whatever remains, so the two levers stack rather than offset. A £50 deposit with a £50 bonus under a 35× deposit-plus-bonus base owes £3,500 of counted stakes; at a 10% table weighting that becomes £35,000 actually staked before the requirement counts as met. Numbers of that size are why the order of operations matters: check the base, then the weighting, then the multiplier, and only then argue about the percentage.

Sticky and non-sticky: where the deposit stays yours

Percentage, cap, multiplier, base and weighting all price the bonus; the sticky question decides who controls your own money while the terms run. A non-sticky offer sits your deposit in front of the bonus: you play with cash, the bonus waits behind it, and a withdrawal before the bonus activates keeps your winnings and forfeits only the untouched bonus. A sticky offer is play credit through and through: it funds spins, it can never be withdrawn itself, and when the wagering ends whatever is left of it goes back to the house.

The harshest sticky variants go further and hold the deposit too. Under those terms a withdrawal request before the requirement clears can forfeit the bonus, the winnings and the deposit balance, or hand the operator a discretionary call on what survives. Between the poles sit parachute structures, where the bonus converts to cash once wagering completes, and hybrid terms where the deposit stays withdrawable but winnings are capped until the requirement finishes. Some terms simply cap what can be withdrawn from bonus play at a fixed multiple of the deposit, which converts the headline into a bounded bet rather than a balance. The label matters less than the sentence about what happens to the deposit on an early withdrawal.

The structure reprices the same headline. The chart in the value section assumes a non-sticky build, because that is the friendliest reading of a 100% match: your £100 is never locked, the worst case is that you lose it at your own chosen pace, and the bonus is an option that pays when the wagering clears. Make the same offer sticky and the floor drops: the whole balance is exposed to the requirement, the bonus cannot be abandoned mid-flight, and the expected value of the identical headline falls accordingly. Two offers with the same five-line price list can still differ by their structure, which is why structure is the sixth line that never gets printed.

Structure also decides what the expiry clock does to you. On a non-sticky build, an expiring bonus wastes only the option: your deposit has been yours throughout, and the worst outcome is a foregone opportunity. On a sticky build with a locked deposit, the same expiry can strand real money: the deposit sits inside the requirement, the clock runs, and the choices are to finish the wagering at the required pace or lose access to funds you deposited in the first place. That asymmetry, more than any percentage, is why this page keeps asking readers to find the structure sentence before they find the match rate.

Spotting the structure takes one search of the terms. Phrases about play purposes, non-withdrawable bonuses or bonus funds existing for wagering only signal sticky builds. A sentence confirming the real cash balance can be withdrawn at any time signals the non-sticky build this page’s charts assume. Where the terms are silent, the cautious reading is the sticky one, because the operator writing vague structure language is not usually writing it in the player’s favour. Watch also for the maximum-withdrawal line on bonus winnings, which caps the upside of a non-sticky bonus after it has already been earned.

From the player’s side of the glass, the order of preference runs: non-sticky with a withdrawable deposit first, parachute second, sticky with a locked deposit last. Price offers in that order and the headline percentage starts to make sense as one input among six. A 400% match on a locked deposit and a 100% match on a free deposit are not in the same business; only one of them lets you change your mind.

What a licensed welcome offer has to print

The baseline for honesty in this market is a licence. Providing remote gambling facilities to people in Great Britain requires an operating licence from the Gambling Commission, and that licence is a matter of public record: the Commission publishes a register of licence holders, searchable by operator name, so a claimed licence can be checked in minutes rather than trusted in seconds.

A licence does not make an offer generous; it makes the offer legible. Licensed operators must follow the Licence Conditions and Codes of Practice, which carry social responsibility requirements on customer interaction and product design, set the level at which customer funds are protected and make age and identity verification a condition of doing business rather than an optional extra. It is also the frame that makes the complaint ladder real: a player who cannot resolve a dispute with a licensed operator can escalate it free of charge to an alternative dispute resolution provider such as IBAS, an escalation route that simply does not exist offshore. The offer has to exist inside that frame, and the frame is the reason the five-line price list from the top of this page is complete on a licensed site: the terms are written for a regulator to read as well as a player.

Advertising rules sit on top. The CAP Code, administered by the Advertising Standards Authority, governs gambling advertising in the UK and includes requirements on protecting minors and on presenting bonuses honestly, so significant conditions and exclusions have to be communicated with the promotion rather than buried behind it. A separate layer covers this page’s own trade: comparisons and affiliate relationships must be disclosed clearly under ASA and CMA expectations for online reviews and comparisons, which is why the commercial listings on this site are kept in their own slot, apart from the modelling, and why the tables here are text rather than paid placement.

The offshore bracket this page models sits outside all of that. An offshore licence is not a UK licence: it brings no entry in the Commission register, no GamStop coverage, no UK dispute route and none of the LCCP fund-protection levels. The jurisdictions commonly serving UK-facing brands include Curaçao and Anjouan, and Curaçao has been reforming its framework with the National Ordinance on Games of Chance, phasing out the master-licence model. None of that substitutes for the British register: any licence claim an offshore operator makes can only be checked on the issuing authority’s own register, and until that line is verified it is a sentence in a footer.

One payment tell separates the brackets quickly. Credit cards are banned for gambling with GB-licensed operators, so a cashier offering a credit card route is announcing, cheaply and accurately, that the British frame does not apply. Debit cards, meanwhile, are unremarkable at both ends. Payment rails are a weak signal on their own, but they are a fast one, and they appear in the comparison table below without needing a single term to be read.

Set the licensed baseline and the offshore offers side by side and the comparison becomes fair in both directions. The licensed rows in the table below show what the British frame tends to print: smaller matches, smaller ceilings, longer-established payment routes and a complaints ladder with actual rungs. The offshore rows show the bracket this page prices: larger percentages, larger caps, wider rails and none of the protections. Both columns are real; they are just selling different things.

Twelve offers side by side: the licensed baseline against the offshore bracket

The table below sets nine licensed British rows against three offshore rows, so the baseline and the bracket this page models share one grid. Ranges are category-typical, compiled from operator-published terms at the time of writing, and each row is a starting point for reading terms rather than a substitute for them. Read every row against the five-line anatomy: the match and the ceiling sit in one column, the wagering range in the next, and the deposits and payout windows fill in the pace of the offer. Rows are text rather than links by design: the pricing lives here, the terms live with the operator.

Figures are category-typical ranges compiled from operator-published terms at the time of writing, not quotes of any single promotion. UKGC-licensed rows are the British baseline shown for comparison; none of them are claimable at the offshore offers modelled on this page. Verify every term on the operator’s own page before you take it.

Two readings fall out of the grid. First, the wagering ranges overlap: 30–45× and 35–45× describe both brackets, so the licence badge does not predict the multiplier, and the multiplier does not predict the base or the weighting that follow it. Second, the structural differences are larger than the numeric ones: payout windows stretch from one to two banking days on the licensed rows to one to five on the offshore rows, minimum deposits run higher at the top of the offshore bracket, and the rails widen exactly where the protections narrow. Price the numbers, then price the frame they sit in.

Run the numbers yourself: the match calculator

Arithmetic beats impressions in this market, and the fastest way to make the arithmetic your own is to run a real deposit through it. The embed below is the same model the charts and tables on this page use, reduced to four inputs and one output, so the worked examples above can be regenerated or contradicted in seconds.

The calculator takes four inputs: the deposit, the match rate, the wagering multiplier and the cap. It ships prefilled with the settings used through this page: a £50 deposit, a 100% match, a 35× multiplier and a £250 cap. On those inputs the bonus is £50, the cap is not binding, and the stakes owed are £1,750 if the multiplier applies to bonus funds alone or £3,500 if it applies to deposit plus bonus. Every figure on this page that depends on those settings can be regenerated with your own numbers.

Three runs are worth trying. Raise the match to 300% and the deposit to £100: the face bonus of £300 is trimmed to £250 by the cap, and 35 times the capped bonus is £8,750 of stakes on the bonus-only base. Drop the multiplier to 30× and the bill falls proportionally; raise it to 45× and the same deposit owes more than the bonus is worth at face value. Hold everything steady and change only the deposit, and the cap line shows you exactly where the percentage stops earning.

What the calculator deliberately leaves out: game weighting, expiry clocks, maximum stake rules and the sticky question from the fifth section. It prices pure staking arithmetic on the assumptions you feed it, which makes it the stakes-owed line of the price list and nothing more. Treat its output as the second half of a comparison; the first half is the terms page of whichever offer you are pricing, read with the six lines from this page in hand.

A last word on inputs: the multiplier belongs to the terms, the base belongs to the sentence after the multiplier, and the cap belongs to the bonus table rather than the banner. Readers who copy the three numbers from advertising copy rather than the terms page will price a different offer from the one they would actually receive, and the calculator will be accurate about an offer that does not exist. Garbage in, precise nonsense out; the model is only as honest as the line items fed to it.
