200% deposit bonus: the mid-pack match, costed

A 200% deposit bonus pays £2 of bonus money for every £1 deposited: the double that tops the matched-percentage range among the offshore rows in the pool below. The figure sizes that bonus at three deposit widths. Everything after it costs the wagering, the caps and the terms that decide what the double is actually worth.

The board below carries the site’s current entries. Cost any card with the method on this page before committing: the structure a 200% match shares matters more than the size its headline prints.

The double as the market’s workhorse

Call it the double: a first deposit matched at twice its value in bonus funds. In the pool this page draws on, the double marks the top of the matched-percentage range among the offshore rows: offers are printed in bands that run up to it and stop there, which is as good a definition of mid-pack as this market offers. The licensed British market rarely goes that far. Its matches run one-for-one against low ceilings, and even its most generous casino row stops well short of a double.

Higher percentages exist further out, and this hub carries pages on them; they buy their headlines with harsher constructions. The double is where the volume sits: enough extra to headline a card, not so much that the terms have to announce their own severity. That ordinariness is the trap. A double reads as familiar, so it is rarely costed.

This page costs it. One model, one wagering multiple, three deposit widths, three caps, runs the same offer at £20, £50 and £100 in, and the comparison table puts the double against the licensed baseline and the neighbouring structures. The aim is not a verdict. It is that a 200% deposit bonus has a price, the price is computable in four lines, and the computation should happen before the deposit rather than after.

The wagering at two hundred percent

Start from the structure. A 200% match credits bonus funds worth twice the deposit, and the wagering multiple then applies to that bonus. Everything else on this page follows from one line of arithmetic: bonus multiplied by multiple equals turnover.

The model uses five stated assumptions:

• the match lands on the first deposit, credited as one lump;
• the multiple applies to the bonus alone: the lighter of the two common constructions;
• slots contribute in full, so the clearing plan stays on slots;
• the maximum stake while clearing is £5;
• the multiple is 35x the bonus, the middle of the band the offshore rows in the comparison table carry.

At 35x on a double, the turnover is seventy times the deposit: the bonus is twice the deposit and the multiple is 35, so 35 × 2 = 70. That ratio is the honest headline of every 200% deposit bonus. It does not care how the offer is phrased, and it scales perfectly, which is the point of reading it at three widths.

Read the middle row. A £50 deposit buys £100 of bonus and £3,500 of required stakes: at £5 a stake, seven hundred rounds of slots before anything unlocks. Cost that turnover at the model’s assumed return of 96p in the pound, a round figure for illustration, not a claim about any title, and clearing carries an expected cost of £140 against a bonus worth £100. On those inputs, the wagering costs more than the bonus pays. A double is not free money; it is a rebate conditional on producing turnover you would not otherwise owe.

Caps on doubles: ceiling, conversion, maximum bet

Three separate limits travel under the word “cap”, and each does different damage to a double.

The first is the up-to ceiling. Take £200 as the model’s input: a double printed against it stops paying bonus once the deposit reaches £100, and the percentage above that line is decoration. At the three widths, £20 and £50 are matched in full, £100 exactly exhausts the ceiling, and anything deposited beyond it buys cash with no bonus attached. The ceiling is the term that decides which deposit makes the most of the offer: below it you leave matched money unclaimed; above it the extra is unmatched by design.

The second is the conversion ceiling: the most that winnings from bonus funds can become withdrawable cash. Where a card sets one, a win above the line during clearing has its excess removed when the bonus converts. On a double this bites hardest, because the bonus balance is large enough for a serious win to build across the long clearing, and the ceiling trims precisely the win that would have made the offer pay.

The third is the maximum bet while clearing, £5 in the model. A stake above the clamp is a breach, and the terms treat breaches as forfeiture of the bonus and its winnings. The clamp’s quieter function is time: at £5 a round, the £100 width needs 1,400 rounds at minimum, which turns a headline into a week or more of prescribed play.

The percentage sells the offer. The caps price it.

What a British licence would change

A 200% match is, in practice, an offshore offer, so the permit comparison belongs in the body of this page rather than a footnote.

Start at the regulator. Gambling within Great Britain answers to one statutory regulator, the Gambling Commission. Since 1 November 2014, any operator serving online gambling to British customers has had to hold a Commission operating licence, wherever that operator is based. An operator that runs such facilities without the licence commits a criminal offence. The player side is different: nobody in Great Britain breaks the law by gambling on a site that lacks one. That asymmetry defines the trade: the legal exposure sits with the operator, and the loss of protection sits with the player.

What the licence buys, from the Commission’s own rulebook for licensees: terms that are fair, plainly worded and never misleading; customer funds kept separate from business funds, with the level of protection published; a free route to independent alternative dispute resolution when a complaint cannot be resolved with the operator; connection to GamStop, so one registration reaches every licensed operator; a public, searchable register of licensees; and a regulator with power to fine, suspend or revoke.

Offshore, none of that applies by construction. On this site, the “offshore” tag on a row records one fact and nothing more: the operator behind it has no Commission licence. The tag makes no claim about the operator’s home country or about any other permits it may hold. Some offshore operators display permits from other jurisdictions. Curaçao licenses online gambling operators serving international customers. A licence from Curaçao carries no British standing: it gives an operator no authorisation to serve gamblers in Great Britain. Whatever a foreign permit says, GamStop’s coverage stops at operators licensed by the Commission. No UK self-exclusion scheme extends beyond that regime to operators outside it.

Set the two permits side by side and the double’s context is plain: a bigger printed bonus on one side, and on the other a thinner set of recourses, no dispute route, no published fund protection, no scheme-wide exclusion. The comparison table prints that difference in its licence column; this section is what the label means.

Tiers around the double

The double has neighbours below and above it, and the neighbours explain its price.

Below sits the one-for-one match, the licensed baseline: modest percentage, low ceiling, lighter multiples. Above sit the treble and the quadruple, printed at the far offshore edge, and they pay for their headlines with harsher constructions: bigger multiples, tighter ceilings, stiffer conversion terms, shorter clocks. This hub carries pages on both, costed the same way as this one.

The double’s middle position is not an accident. A percentage large enough to headline and small enough to be printed on every card is the market’s volume offer. That is also why it deserves costing rather than admiration: the treble’s terms announce themselves, while the double’s terms look ordinary and are not. At seventy times the deposit in required turnover, an uncosted double prices very like its louder neighbours once the caps are read.

The practical reading: treat the percentage as marketing and the multiple, the ceiling and the conversion cap as the offer. Two doubles with the same percentage and different multiples are different products; and that difference is worth more than the gap between a double and a treble.

The comparison table

The table redraws the deposit-match pool for this page: eleven rows, five licensed and six not, with the double-carrying offshore rows put first so the subject leads.

Read the licensed rows as the baseline. One row belongs to a long-running British online casino sitting inside a major betting group; another is a British-flagged casino brand run by a European operator; the third is a European casino group with a mobile-first focus that also holds a British licence. All three set the British pattern: matched or credit-based welcomes inside tight bands, wagering attached. The offshore rows carry the percentages this page costs, in bands several times wider, and the licence column is the divider between the two treatments.

Two columns do the work. The wagering column prices each percentage; the payout window shows what speed means once a licence is absent. Ceilings are not printed here because they are card-specific, which is exactly why the four-step method reads them off the card before depositing.

The four-step method applied

The method has four steps. The £50 width runs through all of them.

One: fix the match and its ceiling. Two hundred percent, ceiling assumed at £200. The ceiling binds at a £100 deposit, so every width up to there is matched in full: the £20 and £50 widths lose nothing to it.

Two: compute the bonus and the turnover. £50 in buys £100 of bonus; 35x on the bonus makes £3,500 of required stakes.

Three: read the four terms that move the maths. Contribution: slots count in full, so the clearing plan stays on slots. Maximum bet: £5, which fixes clearing at seven hundred rounds minimum. Conversion ceiling: the model assumes none binds; on a real card, read the number, because it trims the best outcomes. Expiry: the clock on the wagering, left open in the model because it varies card to card; on a real card, check that the clock is long enough for the rounds that step two demands.

Four: price it. £3,500 of turnover at an assumed 96p return carries about £140 of expected cost against £100 of bonus. Costed, the offer is a rebate of roughly minus £40 on the play the terms demand, unless that turnover was going to be produced anyway, in which case the bonus tops up play already planned, and the sizing question becomes which width your own budget would have deposited.

That last branch is the only one in which a double is straightforwardly worth taking, and it is a statement about the player’s habits, not the offer’s size.

How this page models the numbers

What the model contains: the match at 200%; the multiple at 35x the bonus, mid-band for the offshore rows in the table; slots contributing in full; a £5 maximum stake; a £200 ceiling; and an expected-cost line at an assumed return of 96p in the pound. Every input is a model choice made for readability, and each can be reset inside the calculator, which replays the arithmetic against whatever figures you supply.

What it leaves out: expiry clocks, too card-specific to model honestly; weighting exceptions, because the plan is slots-only; conversion ceilings, which are set per card; and cashier costs such as rail fees or currency conversion, which belong to the payment rather than the offer.

The comparison table’s licence labels follow the site rule: a row prints UKGC licence or No UK licence, and nothing further is claimed about any offshore operator’s permits.

Rounding is display-only: turnover and expected cost are computed unrounded and shown to the pound. The number to carry away is the ratio, not the pound figure. At a 35x multiple on a double, the turnover is seventy times the deposit, and that ratio survives every change of width.
