The payback picture under the GB rules

Every title a GB-licensed operator offers to British players carries a published return to player figure. The duty comes from the Gambling Commission’s remote technical standards, which require RTP publication, so the number sits on the game’s help screen where it can be read before the first spin. A site outside the register carries no such duty, which is why the printed figure doubles as a marker of where an operator stands.

What the figure measures matters as much as where it sits. Return to player is a long-run statistical expectation worked over a very large number of rounds, not a forecast for any single session. A 95.5% band means the game returns £95.50 of every £100 staked across that volume; a single hundred-spin run can finish well above or below the line.

The chart plots the category-typical bands by tier: classic three-reel titles near 95%, feature-led video titles near 95.5%, progressive jackpot titles near 93%, the lowest of the three because a slice of each stake feeds the pooled prize. All three sit inside the wider market band, which commonly runs from 94% to 97%.

Read together, the rule and the bands give two working tools: a duty to publish that licensed sites carry, and a range that makes a printed figure checkable. A title printing 97% sits at the top of the market; a progressive printing 93% is behaving as its tier does. Where nothing is published at all, that absence is information too.

Stake ranges and what a spin costs

Stake size is the lever that turns a band into pounds. A hundred spins at 20p turn over £20; the same run at £1 a spin turns over £100, and the expected cost scales with it: 90p at the video band, £4.50 at the same band on the bigger stake.

Floors and ceilings live in each title’s own stake controls rather than in the cashier, and they move from studio to studio. Where the market’s published numbers speak plainly is granted spins: UK-facing operators commonly price them between 5p and 20p each, offshore-facing operators between 10p and £1, and winnings from granted spins usually carry wagering of their own unless the terms say otherwise.

Deposits frame the outside. The licensed market commonly runs a £5 to £10 standard minimum, with a small family advertising £3; offshore-facing cashiers commonly ask £10 to £20 or the equivalent, with crypto minimums lower. Budget, stake and band are the three inputs the rest of this page works with.

Volatility and picking a fit

Payback and volatility answer different questions. The band says how much comes back over the long run; volatility says how unevenly it arrives. Two titles can share a 95.5% band and behave nothing alike: one dribbles small wins back often, the other says little until a feature lands and pays for the silence.

The tiers carry their own shapes. Classic and steadier video titles spread returns across many small outcomes. Progressive jackpot titles concentrate more of the return in rare, large events, which is why the same bankroll dies faster and jumps harder on that tier, and why its 93% band reads as a fair warning rather than a flaw.

Fit is a budgeting decision before it is a taste. A smaller bankroll stretched across a long session generally survives better on the steadier tiers, where the band does more of the work per spin. A short session with room for swings can carry the jackpot tier, priced knowingly.

Fairness testing and what the licence enforces

For a random-number-generator title on the licensed market, the published rules set the disclosure. The Commission’s remote technical standards require each game’s RTP to be printed, and licence conditions reach past the reels: deposit limits a customer sets themselves, reality checks during online sessions, participation in GAMSTOP and a named adjudication body for complaints.

Those requirements hand a reader things to verify rather than claims to trust. The public register lists who holds a licence, the help screen carries the RTP, the terms name the ADR provider. On an offshore-facing site the checks thin out: no British register entry, no route to a UK-approved adjudication body, and whatever fairness disclosure exists is what the operator chooses to print. Claims pointing at Curaçao or Anjouan can be tested against the registers those authorities run, and the test matters because a claim is not an entry.

The table sets the licensed baseline against the offshore-facing corner of the slots market on the terms a cashier prints: category-typical texture, not a quote of any promotion, so the difference between the two licence classes shows in numbers rather than adjectives.

Figures are category-typical ranges compiled from operator-published terms at the time of writing, not quotes of any single promotion. UKGC rows are the British baseline, shown for comparison; they cannot be claimed at offshore operators.

Two lines of the texture deserve a second look. Wagering tends to run heavier in the offshore corner, and several licensed operators publish no win cap on bonus winnings where caps are common offshore. Neither fact settles an offer on its own; together they move the expected value the session model prices further down this page.

How to read a paytable

A paytable is the title’s contract with the player, and it repays ten minutes. The first block is the symbol ladder: what each symbol pays, at which line counts, and how the wild differs from the scatter. The second is the line structure, where older titles run fixed paylines and newer ones run ways or cluster systems, and where the stake control shows whether the displayed price is the total bet or a per-line slice multiplied out.

The third block carries the features and their triggers: which symbols start the round, how many spins it grants, which multipliers apply and whether they reset. The fourth ties the title back to this page: the published RTP, usually in the help screen, sitting in one of the bands on the chart.

A last habit links paytable to cashier. The paytable governs the game; the bonus terms govern the money. The help screen states the return and the features; the terms state what a spin on that title is worth while a bonus is active. Reading the two side by side is the difference between knowing the game and knowing the deal.

How slots behave on a phone

The same account, wallet and terms follow a title from desk to phone. Licensed lobbies run in the browser or through an app, reels are built portrait-first, and stake controls compress into a slider with steppers. Nothing in the game’s maths changes with the screen: the band is the band on either device.

Payment is where mobile differs. Device wallets such as Apple Pay and Google Pay sit over a debit card: deposits are instant, and withdrawal support depends on the cashier, with many operators routing payouts back to the underlying card. Pay by mobile is the other mobile-first option, and it carries three limits: deposits only, a common carrier cap of £10 to £30 a transaction, and no withdrawal on that rail, so a bank route must exist for cashouts.

Session hygiene follows the device rather than the game. A stake chosen at the kitchen table reads differently on a commute, and reality checks, where the licence requires them, show on the small screen as they do on the large one.

A worked session, priced first

The model takes one session shape and prices it band by band: a hundred spins at 20p, £20 of turnover, no bonus attached. At the classic band the expected return is £19.00 and the expected cost £1.00; at the video band £19.10 and 90p; at the jackpot band £18.60 and £1.40. The same arithmetic extends to granted spins, where the terms take over: winnings arrive in expectation at the band, and a multiplier on those winnings clears at the same return rate, which is where grants earn or lose their keep.

The table carries both shapes, cash sessions and granted spins, on the assumption named beneath it.

Session modelled	Turnover	Expected return	Expected cost	Net expected
Cash session, classic band	£20.00	£19.00	£1.00	-£1.00
Cash session, video band	£20.00	£19.10	£0.90	-£0.90
Cash session, jackpot band	£20.00	£18.60	£1.40	-£1.40
Granted spins, video band, winnings at 35x	£668.50	£19.10	£30.08	-£10.98
Granted spins, classic band, winnings at 35x	£665.00	£19.00	£33.25	-£14.25
Granted spins, jackpot band, winnings at 35x	£651.00	£18.60	£45.57	-£26.97

The model reads each band’s return off the chart and prices one hundred spins at 20p. Where a wagering multiplier enters the working, granted spins are priced at 35x the winnings, the level offers of this sort tend to print, and that turnover is cleared at the band’s own return, which is why the grant rows turn negative while the cash rows cost pennies. For the grant rows, the turnover column is the clearing requirement the winnings must pass through, not a stake from the player.

The grant rows are the honest headline. At 35x on winnings and the bands shown in the chart, the expected cost of clearing outweighs the winnings themselves on every tier, which is why per-spin value, cap levels and the occasional no-wagering shape move the outcome more than headline spin counts do. Variance lets an individual grant finish in profit; expectation, across many grants, does not.

The calculator runs the same arithmetic on fresh inputs: spins, per-spin value, a wagering multiplier where winnings carry one, and a cap where the terms set one. The prefill matches the worked session, with the multiplier and cap at zero because a plain cash session carries neither; fill them to price a grant instead.

A checklist before the first spin

A title and its cashier can be checked in a few minutes, and the checks belong before the deposit rather than after it. The list runs from the game to the money to the licence.

• The RTP is printed on the title, and you know which band it sits in.
• The stake range matches the session budget you actually brought, not the one you hoped for.
• Where spins or a match are attached: what the wagering multiplies, the bonus or the winnings; how many times; which cap applies; when it expires.
• The licence: a GB register entry, or an offshore label whose costs you have read rather than skimmed.
• The rails: how the deposit arrives, and which route carries the withdrawal back, since some rails work one way only.
• The payout window for that route, in hours or days, as the cashier prints it.
• The protections: deposit limits you set yourself, reality checks on the session, and whether a self-exclusion scheme reaches the site at all.

None of these steps takes longer than the session it precedes, and each turns a claim into a check. The offshore label on this page is the short version of what is given up when the register does not reach a site; the helpline and the exclusion scheme named below are the two fixed points worth having before anything is staked.
