18+ only. Gambling with real money involves risk — never stake more than you can afford to lose. Terms apply at every operator and can change without notice; always read the current terms on the operator's own site. Free, confidential help: BeGambleAware.org.
This page explains how bonuses work rather than recommending particular casinos. You won't find amounts, spin counts, promo codes or a ranking here — offers and their terms change constantly, and a bonus headline shown without its full conditions is misleading. What you get instead is how to read the terms and how to cost out the wagering, so you can judge any offer on the operator's own page.
A casino bonus is never a gift — it's a contract. In exchange for extra funds in your account you agree to turn them over a set number of times, in named games, inside a time window and under a cap on each individual bet. Those four conditions, not the percentage in the headline, decide what the bonus is worth.
The good news is that all of it can be worked out on the back of an envelope. Multiply the bonus by the wagering requirement, then multiply the result by the house edge of the game you plan to clear it on. That number is the statistical cost of the “free” money. The worked examples below run that calculation on round figures.
It's worth knowing what this site is and isn't while you read. We publish free demo versions of slots only: we don't run real-money games, we don't take deposits and we have no bonuses of our own to hand out. That's precisely why we can write about promotions without selling them.
The five common types
Deposit match (welcome bonus)
The casino matches a percentage of your deposit — a 100% match doubles what you put in, as bonus funds. It's the most common shape of welcome offer.
Watch: The headline percentage is the least important number in the offer. What matters is the wagering attached to it, and whether that multiplier applies to the bonus alone or to bonus plus deposit.
No-deposit bonus
A small amount of bonus money or a handful of spins credited just for registering and confirming the account, with no payment at all.
Watch: Almost always carries a low withdrawal cap, so treat it as a free trial of the site rather than a way to win.
Free spins
A set number of spins on named slots, at a fixed stake the casino chooses — usually the lowest the game allows.
Watch: Whether winnings arrive as cash or as bonus funds. Cash carries no wagering; bonus funds do.
Cashback
A percentage of net losses over some period, returned to you — most often settled weekly or monthly.
Watch: Whether it's paid as real money or as bonus funds with wagering of its own, and whether it's calculated on losses or on total wagered. The difference can be several times over.
Reload bonus
A smaller match offered to existing players on later deposits, often restricted to particular days of the week.
Watch: Usually a lower percentage than the welcome offer, but sometimes with markedly better wagering — so compare the two rather than assuming.
No-deposit bonuses — what they actually are
A no-deposit bonus is a small amount of bonus money, or a package of spins, credited without any payment. The conditions are registration, a confirmed email address or phone number, and increasingly full identity verification with a document. To the casino this is a customer-acquisition cost rather than a gift, and the whole structure of the offer follows from that.
Which is why it is rarely as free as it looks. You will usually meet three restrictions at once that are rarer on deposit matches: a high wagering multiplier, a hard withdrawal cap and a short expiry window. The cap matters most — it means even a large win won't change the figure that reaches your balance.
Then there's the condition that is easy to forget: to withdraw anything won from a no-deposit bonus, many casinos require one deposit of your own money first. The offer is no-deposit; the withdrawal isn't.
None of this makes the offer worthless. It works as a way to see how a casino behaves in practice: how long verification takes, whether support answers, what the cashier looks like, what the withdrawal limits are and whether the site works properly on a phone. That's the right way to read it — a test of the operator, not a source of income.
Five things to check before you click “claim”
- The wagering multiplier, and whether it applies to the bonus amount or to the winnings from the free spins.
- The withdrawal cap on this bonus — as a cash figure or as a multiple of the bonus.
- How long you have to complete wagering, counted from when the funds are credited rather than from registration.
- Which games count towards wagering, and whether the slot you want to play is excluded.
- Whether withdrawing requires a prior deposit of your own money or identity verification with a document.
Free spins — how their value is calculated
The spin count in the headline tells you nothing until you know the stake behind it. The casino sets the value of each spin itself, and it is almost always the minimum the game allows. The value of the whole package is the spin count multiplied by that stake — usually a modest figure, even when the headline promises a hundred spins.
The second number is how winnings are settled. Spins described as “no wagering” pay out as cash and are worth exactly what the counter shows. Far more often, winnings from free spins land as bonus funds with a multiplier of their own — and then the wagering is calculated on the winnings, not on the value of the spins. That single difference can move the value of a package severalfold.
The third is the limits: maximum win per spin, and the withdrawal cap on the promotion as a whole. With those clauses in place, a big hit in a bonus round is trimmed back to the cap regardless. The worked example below shows how the three numbers combine into the real value of a no-deposit spins package.
A worked spins package
This is not an offer, just arithmetic on round numbers — but the conclusion is typical: a package worth a few pounds can demand £1,050 of turnover and then limit the payout to the figure in the last row. All of these values appear in the promotion's terms; if one of them doesn't, that is information too.
Wagering, step by step
Wagering is the number that says how many times you must stake the bonus amount before winnings can be withdrawn. “35× bonus” means the sum of your bets has to reach thirty-five times the bonus. It isn't about winning that amount, or depositing it — it's about turning it over in play, even if that means the same money circulating many times.
The first trap is in what gets multiplied. “35× bonus” and “35× bonus + deposit” read almost identically and differ by a factor of two in how much play they demand for the same headline. Always check what the multiplier applies to — that one line of the terms matters more than the rest of the offer put together.
Take a £100 bonus at 35× wagering:
If the multiplier covers bonus plus deposit, a deposit matched with an equal bonus gives a base of £200, and 35× applied to that base is £7,000 staked before a withdrawal is possible. Same headline, twice the play.
Now put an RTP against it. A slot with 96% RTP returns players 96% of everything staked over the long run, so the house keeps roughly 4% of turnover. At £3,500 of turnover the expected cost of clearing is about £140 — more than the £100 bonus is worth. At a gentler multiplier the same bonus needs far less turnover and comes out ahead. The whole difference sits in one number.
| £100 bonus at… | Must stake | Expected cost at 96% RTP | Net |
|---|---|---|---|
| 10× wagering | £1,000 | ≈ £40 | +£60 |
| 20× wagering | £2,000 | ≈ £80 | +£20 |
| 35× wagering | £3,500 | ≈ £140 | −£40 |
| 50× wagering | £5,000 | ≈ £200 | −£100 |
These are long-run averages, not predictions — any individual attempt can land far either side, which is the whole point of variance. The table also ignores withdrawal caps, game weighting and expiry, each of which pushes the real figure further down. Treat it as a floor on the cost, not a forecast of the outcome.
Sign-up bonus vs deposit bonus
“Sign-up bonus” and “welcome bonus” get used interchangeably in advertising, but they cover two different constructions. A sign-up bonus (no deposit) is credited for opening and confirming an account. A deposit bonus only triggers once you pay in, and is calculated as a percentage of that payment.
The practical difference is risk. A no-deposit bonus is small, but none of your own money is exposed — the worst case is wasted time. A deposit match can be many times larger, but it requires a payment, and if you don't complete the wagering in time you lose not just the bonus but usually anything won with the bonus funds too.
The third difference is withdrawal. With a deposit match your own deposit normally stays yours, although plenty of terms lock it until wagering is finished, and a maximum-win cap appears less often. With a no-deposit bonus the cap is the rule, not the exception.
| Condition | Sign-up bonus (no deposit) | Deposit bonus |
|---|---|---|
| Payment required | No | Yes — the bonus is a percentage of the deposit |
| Typical size | Very small | Much larger, with a cap on the bonus amount |
| Wagering | High, on the bonus or on spin winnings | Usually lower, but sometimes on bonus plus deposit |
| Withdrawal cap | Almost always | Less often, but it happens |
| Expiry | Short, often a few days | Longer, typically a week to a month |
| What you risk | Your time and your data | The money paid in, plus your time |
Excluded games and game weighting
Not every bet counts towards wagering equally. Terms assign each game a percentage: slots typically 100%, roulette around 10%, blackjack and other table games a few per cent or nothing, and some casinos exclude whole categories including live casino. A weighting of 10% simply means that for every £10 you stake, £1 is credited towards the requirement.
The consequence is purely arithmetic and quite brutal: the same requirement at 10% weighting needs ten times the turnover it would on slots. So a bonus that looks reasonable to a slots player is effectively impossible for someone who wants to play roulette.
Excluded-game lists work separately. Operators generally block the highest-RTP titles and bonus-buy slots while wagering is active, because those are where clearing costs the casino least. Sometimes a game isn't excluded but its bets don't count at all — in the terms those are two different things: one leaves you with no progress, the other voids the bonus.
| Game category | Typical weighting | Turnover needed to clear £3,500 |
|---|---|---|
| Slots | 100% | £3,500 |
| Video poker | 20% | £17,500 |
| Roulette | 10% | £35,000 |
| Blackjack and table games | 5% | £70,000 |
| Live casino | 0% | Doesn't count at all |
The weightings above are typical values found in many sets of terms — they are not universal. The numbers that apply to a particular promotion are always in its own conditions, under game contribution.
Maximum bet while a bonus is active
This is the clause that voids winnings most often. While a bonus is active the terms cap the size of each individual bet — usually as a cash figure or as a percentage of the bonus. Breaching it once, even accidentally through an autoplay setting, commonly voids the entire bonus and everything won with it.
Mind the definition of a bet. The cap normally covers not just the spin stake but the cost of a bonus buy, the stake in a gamble round, and the total staked in a single round of a table game. If you're playing with an active bonus, the safe approach is to set the stake once, well under the cap, and leave it alone until wagering is done.
A typical clause reads: “maximum bet while wagering — £5”. There is no margin and no discretion in it: the casino's system flags a breach automatically, including after the fact when a withdrawal is reviewed. It is the most common reason a payout request is refused.
Withdrawal cap (max cash out)
The withdrawal cap is the ceiling on what you can move from bonus play into your own balance. It appears as a cash figure or as a multiple of the bonus — “maximum withdrawal: five times the bonus”, for instance. Anything above the cap is simply removed from the balance once wagering finishes.
The cap has a side effect that rarely gets mentioned: with one in place, high volatility stops working in your favour. If the maximum is a couple of hundred, a slot that pays rarely but very large is a worse choice for clearing than a steady low-volatility game, because everything above the ceiling is trimmed away anyway.
With a £10 bonus capped at £50, even a win many times larger pays out £50. That is 5× the bonus, and it is the real best case for the offer — no headline about big wins changes that number.
Expiry windows
The window normally runs from the moment the funds are credited rather than from registration, and is most often between seven and thirty days. Once it closes, an uncleared bonus and anything won with it are forfeited — without warning and usually without any way to extend.
Free spins often carry a second, shorter deadline: the spins themselves expire after a few days, and any winnings then get their own window for wagering. Two clocks in one promotion is standard rather than unusual — and it's the shorter one that decides whether you finish.
It helps to convert the window into playing time. Clearing £3,500 at £0.50 a spin is 7,000 spins to get through. At an unhurried five hundred spins an hour that's 14 hours at the machine, and you have 7 days. If those numbers don't fit the free time you actually have, the bonus can't be cleared without raising stakes — which means risking the maximum-bet clause.
The terms that decide it — a checklist
- Wagering requirement
- How many times the bonus must be turned over before winnings can be withdrawn — and whether the multiplier applies to the bonus alone or to bonus plus deposit.
- Game weighting
- The percentage at which bets in a given game count towards wagering: slots typically 100%, roulette around 10%, some games 0%.
- Maximum bet while wagering
- A cap on the stake you may place while a bonus is active. Breaching it once commonly voids the bonus and everything won with it.
- Withdrawal cap
- A ceiling on what you can take out from bonus play — quoted either as a cash figure or as a multiple of the bonus.
- Expiry
- The window to complete wagering, often 7 to 30 days, counted from when the funds are credited.
- Excluded games
- Titles that don't count towards wagering or are blocked outright — usually the highest-RTP and bonus-buy slots.
- Verification and first deposit
- Many casinos only pay out bonus winnings after full identity verification, and on no-deposit offers after at least one deposit of your own.
Red flags
Concrete, checkable warning signs. Each of these can be confirmed in the terms in a couple of minutes — and if it can't be confirmed, the absence of the information is itself the answer.
- Wagering applied to bonus plus deposit in the small print, while the headline implies the multiplier is on the bonus alone.
- A wagering multiplier above roughly 50×, which makes the arithmetic in the table above clearly unfavourable whatever the bonus size.
- A maximum-bet limit buried in the general terms rather than shown alongside the offer.
- A withdrawal cap on a deposit-match bonus — normal for no-deposit offers, much less so here.
- An expiry window shorter than the wagering realistically needs at the stakes you intend to play. Work that out before depositing, not after.
- Terms that let the casino change or withdraw the promotion at any time without notice.
- No last-updated date on the promotion's terms, or terms that are only visible after you register and log in.
- Any site promising that demo credits or bonus funds can be converted straight to cash. Demo play does not pay out and never has.
- No licence or regulator named anywhere on the site. If you don't know who issued the licence, you don't know where to complain when a withdrawal doesn't arrive.
Casino bonuses — frequently asked questions
- Is a no-deposit bonus really free?
- It costs no money, but it costs data and time: registration, verification and the wagering you normally have to clear before withdrawing anything. On top of that a cap limits the best possible outcome. It's a free trial of the casino rather than free money.
- What does “35× wagering” actually mean?
- That the total of your bets must reach thirty-five times the bonus amount before winnings become withdrawable. It isn't about winning or depositing that figure, only about turning it over — the same money can circulate many times, as long as the stakes add up. The full calculation is in the table above.
- Can a bonus be withdrawn without wagering?
- Only where the offer says “no wagering” in as many words. Those are rare and usually very small, and the winnings are paid as cash. In every other case wagering is a condition of withdrawal and there is no way around it.
- Why did the casino void my bonus winnings?
- The most common reasons are breaching the maximum bet, playing an excluded title, letting the expiry window close, and requesting a withdrawal before wagering was complete. After that: incomplete identity verification, or a second account opened from the same device.
- Are free spins worth what the headline says?
- Rarely. The value of a package is the spin count times the stake per spin, which the casino usually sets at the minimum. Then wagering is calculated on the winnings and a cap is applied. A hundred spins at the lowest stake is worth noticeably less than the advert suggests.
- Deposit match or free spins — which is better value?
- It depends how you play. Spins are simpler and cheaper in risk, needing no deposit or a small one, but they cap the upside low. A deposit match gives more freedom and a higher ceiling at the price of a payment and more wagering. Compare the cost of clearing, not the headlines.
- Can I clear wagering on table games?
- You can, but it seldom pays. Table games usually weight at 10% or less, so the same requirement consumes many times the turnover, and some casinos exclude them from promotions entirely.
- Can a casino change bonus terms while I'm playing?
- Terms generally include a clause allowing a promotion to be amended or withdrawn. So it's worth keeping the version of the conditions you agreed to — a dated screenshot is a stronger argument in a dispute than memory.
- Do you publish bonus codes or casino rankings?
- No. We don't run real-money games, we don't take deposits, and we publish no amounts, codes or rankings of offers. Bonuses change too fast for such a list to be honest, and a headline without the full terms is misleading. The current conditions are always on the operator's own page.
- Where can I test a slot with no risk at all?
- In demo mode. Every slot in our library runs on play-money credits: no deposit, no registration and no wagering to clear, with the same maths and the same features as the real-money build.
A simpler option
If the goal is to learn a game rather than to chase a balance, no bonus beats demo mode. Every slot in our library runs on play-money credits: no deposit, no bet cap, no deadline and no wagering to clear. The same maths, the same bonus rounds and the same RTP the studio publishes.
Demo play doesn't pay out — which is exactly what makes it an honest testing ground. You can see a slot's volatility, how often the bonus round triggers and whether the game holds your attention at all, before deciding whether you want to play for real money. And if you're after write-ups of particular titles, start with our slot reviews.
