Free Spins at Casinos Not on GamStop
Free spins are the most common promotion in online casino marketing and the most misleading. They are also, unlike most things on a casino homepage, capable of being valued precisely — you just have to do a small amount of arithmetic that the marketing is designed to discourage.
The problem is the unit. “100 free spins” is a number with no meaning on its own. Spins are not all worth the same, the winnings from them are not usually yours outright, and the conditions attached can turn a genuinely generous offer into one with a negative expected value. Two casinos can both advertise 100 spins, and one offer can be worth several pounds while the other is worth nothing at all.
This page is about the arithmetic. It sets out how to convert a spin count into a real figure, what the difference is between no-deposit spins and the spins attached to a deposit bonus, and which conditions do the actual work of deciding whether an offer is worth claiming. All of it applies equally to the 10 casinos in our comparison that advertise spins in their headline offer.
Bonus terms change frequently and vary between sources. The figures below are the ones most commonly published, and we have flagged where published accounts disagree. Before you claim anything, read the terms on the operator’s own site — that document, not this page, is what you are agreeing to.
What a free spin is actually worth
A free spin is worth its stake, not its count. The arithmetic starts with the spin value — the amount that is staked on your behalf for each spin — and multiplies.
100 spins at £0.10 is £10 of staking. That is the honest headline figure, and it is the first number you should look for, because most offers do not state it. Spin values in this market are commonly £0.10, with £0.20 and £0.25 on higher-tier offers and £0.05 on the cheaper ones. The same 100 spins are therefore worth anywhere between £5 and £25 depending on a detail the advert usually omits.
That £10 is not £10 in your pocket, either. It is £10 of play, and play has a cost. At a 96% RTP — a typical figure for a modern slot — £10 of spins returns £9.60 on average and costs £0.40. So the spins themselves are worth about £9.60 in expected terms before any bonus conditions are applied.
Then the conditions apply, and this is where the value usually disappears. Winnings from spins are almost always credited as bonus money with a wagering requirement attached. Take the common case of 40x on winnings:
- 100 spins at £0.10 = £10 of staking
- Expected return at 96% RTP = about £9.60 in winnings
- 40x wagering on those winnings = £384 of staking to clear them
- Expected cost of clearing £384 at 96% RTP = about £15.36
- Net expected result = roughly minus £5.76
In other words, at 40x wagering the offer has a negative expected value before you even start. You are being given £9.60 and asked to run £384 through a game with a 4% house edge in order to keep it. The maths does not work, and no amount of spin count changes it.
Now run the same offer at 10x wagering. £9.60 × 10 = £96 of staking, with an expected cost of about £3.84. That leaves a net expected result of roughly plus £5.76 — the identical spins, on better terms, are worth more than five pounds instead of less than nothing.
Wagering decides the value of a spin offer, not the spin count. The difference between 40x and 10x on the same 100 spins is the difference between an offer that costs you money and one that does not. This is why a casino advertising “50 free spins, no wagering” can be making a better offer than one advertising “500 free spins” with 50x attached.
Two assumptions to be explicit about, because the calculation above is only as good as them. First, 96% RTP is an assumption; the actual return depends on which game the spins are valid for, and spin offers are frequently restricted to one specific title whose RTP may be higher or lower. Second, the calculation assumes you would not otherwise have staked that money. If you were going to play anyway, the spins are worth less than the figures suggest, because they have displaced spending you would have made regardless.
No-deposit spins vs bonus spins
There are two distinct products here, and they behave differently enough that treating them as one thing leads to bad decisions.
Bonus spins
These are the spins attached to a deposit. You deposit, you get a match bonus, and some spins come with it. This is the standard offer in this market and it is what most of the headline figures on our comparison table refer to. Typical counts run from 20 to 200 spins at £0.10 each, credited in batches over the first few days after the qualifying deposit.
Winnings from bonus spins are almost always credited as bonus money, not cash, and carry the same wagering requirement as the deposit bonus itself — commonly 35x to 50x on the bonus amount. They are also usually subject to the same maximum-bet clause, so a large spin while the bonus is active can void the whole thing.
No-deposit spins
These are spins you receive without depositing anything, usually for registering. They are genuinely rarer than the marketing implies, and at offshore casinos they are rarer still: none of the ten casinos we compare advertises a no-deposit spin offer in its headline bonus. Every free-spin offer in our table is attached to a deposit.
Where they exist, the pattern is consistent and worth knowing before you get excited. Counts are small — typically 10 to 50 spins, at £0.10 or occasionally £0.20. Winnings are capped at a low figure, often between £20 and £100, so a 5,000x win becomes the cap. The wagering on those winnings is usually high, frequently 40x or more. And in nearly every case you must make a deposit and complete verification before you can withdraw anything at all, which means a no-deposit offer is usually a no-deposit trial rather than a no-deposit payout.
That does not make them worthless. A no-deposit offer is the only way to see how a casino’s registration, verification and game delivery actually work without risking money, and for that purpose it has real value. It is just not the free money the phrasing suggests.
Wager-free spins
A third category is occasionally advertised: spins whose winnings are paid as cash with no wagering requirement at all. Where this is genuine it is the most valuable form of the offer by a wide margin, because the winnings are worth their face value rather than the much smaller figure that survives a wagering requirement. It is also rare, and the phrase is sometimes used loosely to mean winnings credited as bonus but with a low wagering multiplier. Read which one it is before assuming.

The ranking follows our published criteria — licence, bonus terms, withdrawal terms, payments, support tools and the small print — and not the size of the spin offer or the commission we earn. We disclose the commission arrangement on the affiliate disclosure page, and the method behind the ranking is on how we rate.
Which casinos advertise spins
10 of the ten casinos in our comparison mention free spins in their headline offer. Every casino in this group attaches spins to its welcome package, which is now the norm rather than the exception in this segment — the differentiator is no longer whether spins are offered, but how many, at what value per spin, and whether the same wagering that applies to the cash bonus applies to what the spins win.
The conditions that matter
Five terms decide what a spin offer is worth. The spin count is not one of them. The figures below are the ranges most commonly seen at casinos in this market.
| Condition | What you will typically see | Why it decides the value |
|---|---|---|
| Spin value | £0.10 per spin most often; £0.05 to £0.25 across the range | Multiplies the count. 100 spins are worth £10 at £0.10 and £5 at £0.05. If the value is not stated, the offer cannot be valued at all — and that omission is usually deliberate. |
| Eligible game | One named slot, occasionally a small selection | The game sets the RTP, which sets the expected return on the £10 of staking. It also decides the volatility, so it decides whether the £9.60 arrives as a steady trickle or as one improbable spin. |
| Wagering on winnings | 35x to 50x on winnings at most casinos in this market | The single most important term. At 40x, the expected cost of clearing the winnings exceeds the winnings themselves, and the offer becomes negative in expected value. At 10x the same spins are clearly worth having. |
| Maximum win from spins | £20 to £100 on no-deposit offers; £100 to £500 on bonus spins | Caps the tail. A slot with a 5,000x maximum win cannot deliver it if your winnings are capped at £50. The cap is not a hidden trick — it is normally stated — but it materially changes what you are being offered. |
| Expiry | 24 hours to 7 days from credit; often 24 to 72 hours | Short windows force you to play when the casino wants, not when you want. A 24-hour expiry on 100 spins is a demand to play that day, which is not a condition that works in your favour. |
| Maximum bet while clearing | £2 to £5 per spin | Breach it and the bonus and any winnings from it can be voided. Higher-stakes players are the ones caught, because the cap applies until wagering is complete. |
| Minimum qualifying deposit | £10 to £20 | Determines the smallest amount you can put at risk to claim the offer, and sometimes excludes e-wallets or certain payment methods from qualifying at all. |
If you take one habit from this page, take this: before claiming any spin offer, find the spin value, find the wagering on winnings, and multiply. If the wagering number times the house edge is larger than the spin value, the offer is not a gift — it is a prompt to deposit. That is not a scandal, and it is not unique to casinos outside GamStop, but it is worth knowing before you read “500 free spins” and assume you have been given something.
For context on the other side of the ledger, our no wagering casinos page covers which operators in this market publish the lowest wagering requirements, and the slot sites page explains why the RTP of the game your spins are tied to matters as much as the wagering multiplier.
Red flags
None of the following is illegal and none of it is unusual. All of it makes an offer worth less than it appears, and all of it is visible in the terms before you claim.
- The spin value is not stated. “100 free spins” with no value is an incomplete offer. Any operator that wants you to know what you are getting will state the value; the ones that do not are relying on you reading “100” as a large number.
- The maximum win cap is low relative to the count. A cap of £20 on 100 spins means you are playing a game whose upside has been removed. Capped offers can still be worth claiming for a low-risk trial, but they are not a chance at a large win and should not be treated as one.
- Wagering of 40x or more on winnings. As the arithmetic above shows, at 40x the expected cost of clearing the winnings exceeds their value. An offer can be worse than no offer, because it invites you to deposit and play to clear a requirement that was never going to pay out.
- Spins valid on one low-RTP title. The game restriction is legitimate and normal, but if the single eligible game is running at a low RTP setting, the spins are worth less than the same spins elsewhere. Check the game’s information screen — it takes seconds and it is the only reliable source.
- Expiry measured in hours. A 24-hour window is a pressure tactic, whether or not it is intended as one. It also makes it more likely that you will play at a time you would not otherwise have chosen.
- “Free” spins that require a deposit to release. Some offers credit the spins at registration but lock the winnings until a qualifying deposit is made. That is a deposit bonus with extra steps, and it should be compared as one.
- Winnings credited in a currency other than GBP. If the bonus balance is held in EUR or USD, you absorb a conversion spread on the way out. Where a casino does not support GBP accounts, that cost applies to everything, not just the spins.
One thing that is not a red flag: a wagering requirement existing at all. Every bonus in this market carries one, because no operator gives away cash. The question is always the number, never the presence of the term.

Frequently Asked Questions
How much are 100 free spins worth?
It depends entirely on the spin value, which is the figure the advert usually leaves out. At £0.10 a spin, 100 spins are worth £10 of staking. At £0.05 they are worth £5; at £0.25 they are worth £25. That staking value is not the same as money in your pocket — at a 96% RTP, £10 of spins returns about £9.60 on average, and any wagering requirement on those winnings reduces the figure further.
What is the difference between no-deposit spins and bonus spins?
No-deposit spins are given for registering, without any payment. Bonus spins come attached to a qualifying deposit and are usually part of the welcome package. No-deposit offers are rarer, smaller — typically 10 to 50 spins — and almost always come with a low maximum win cap and a requirement to deposit and verify before you can withdraw anything. Their real value is as a low-risk way to see how the casino works — low-risk rather than risk-free, because you still have to deposit to withdraw anything.
Are free spins really free?
The spins cost you nothing, but they are not a gift of money. Winnings are normally credited as bonus funds with a wagering requirement attached, and often capped at a maximum amount. At 40x wagering the expected cost of clearing the winnings is higher than the winnings themselves, which makes the offer negative in expected value. At low wagering — 10x or less — the same spins are genuinely worth having.
What wagering requirement is attached to free spin winnings?
At the casinos we compare, most offers state 35x to 50x on winnings, with 40x the most common single figure. Some operators publish different numbers in different places, so confirm it in the bonus terms before you claim. The wagering applies to the winnings, not to the spins, and it usually carries a maximum-bet clause as well — commonly £2 to £5 a spin — which can void the bonus if you breach it.
Do free spins have a maximum win?
Often, yes, and the cap is the term most players miss. No-deposit offers frequently cap winnings at £20 to £100; bonus spins at £100 to £500. A cap matters because it removes the tail of the distribution: a slot with a 5,000x maximum win cannot deliver it if your winnings are capped at £50. The cap is normally stated in the terms, so it is a question of reading rather than trusting.
Which game do free spins usually apply to?
Most spin offers are restricted to one named slot, sometimes with a small selection as an alternative. That matters because the eligible game sets the RTP and the volatility of your spins. A game running at a lower RTP setting makes the same 100 spins worth less than they would be elsewhere. The in-game information screen shows the published return figure, and it is the only reliable place to check it.
How long do I have to use free spins?
Typically 24 hours to seven days from the moment they are credited, with 24 to 72 hours the most common window at the casinos we compare. Expiry dates are worth checking before you claim, because a short window obliges you to play on the operator’s schedule rather than your own. Spins are usually credited in batches, and each batch can carry its own expiry.
Can I withdraw money won from free spins immediately?
Usually not. Winnings from spins are credited as bonus money and cannot be withdrawn until the wagering requirement is cleared in full. No-deposit offers additionally require a qualifying deposit and completed identity verification before any withdrawal is processed, which means the first cash out from a no-deposit offer is rarely the small amount the offer implies. Send your ID documents early — verification is the usual bottleneck.
