40 free spins: the real value

40 free spins explained in one minute

A 40 free spins bonus gives you forty paid-for rounds on a slot the casino has chosen. You don't stake anything on those rounds; the casino covers the stake, usually 10p, and you keep what they return under the offer terms. Forty 10p spins are £4 of play. At a typical 96% RTP, the average return is about £3.84, though forty spins can easily finish well above or below that.

Spins are only half the market. Plenty of welcome offers give bonus money instead, as a percentage of your deposit. Comparing the two in pounds is the main purpose of this page. For every spin offer size, start at our free spins hub.

18+. Terms apply to every offer on this page. Slots cost money to play, the house edge applies to every spin you pay for, and a bonus doesn't change that.

Who offers 40 free spins? Not our partners

We checked all five partner offers on 5 October 2026, and none of them is a 40 free spins deal. Three partners give spins: PlayOJO 80, Coral 100 and Ladbrokes up to 500, all at 10p and all without wagering on winnings. The other two, Casumo and 10bet, give deposit-match bonuses. We compare all five with a 40-spin bundle below.

What 40 free spins are worth at 10p, 20p and 40p

The headline count is only half the value. Multiply it by the stake per spin, which the terms should state, to get the face value.

Spins above 20p are unusual in welcome offers. Our page on what stake free spins are played at explains why most casinos settle on 10p.

40 free spins or a deposit match: which gives more?

A wager-free spin bundle and a match bonus with wagering can be compared on their average value once you subtract the expected cost of wagering. Wagering cost is roughly the amount you must stake multiplied by the house edge. We use a 4% edge for slots throughout.

On paper the match bonuses carry more average value, but they come with more conditions: Casumo caps bets at £5 while a bonus is active, 10bet gives only 3 days to finish wagering and caps bonus winnings at £1,000, and both restrict games and payment methods. Wager-free spins carry fewer strings. And these figures describe the bonus alone: your own deposit is played at the same house edge, so a bigger deposit means bigger average losses, not a cheaper way to gamble. Our match bonus vs free spins comparison and our guide to the expected value of a casino bonus go deeper.

Deposit £10 get 40 free spins: how the format works

Most 40-spin offers you'll see follow one of two patterns. In a deposit offer, the spins follow a qualifying deposit, and that money sits in your balance to play with or withdraw. In a bet-and-get offer, you must stake a set amount on slots before the spins arrive, which means the house edge has already been applied to that stake.

Our partners use both. PlayOJO's 80 spins follow a first deposit of at least £10. Coral and Ladbrokes ask you to deposit and then bet or spend £10 on slots. Our pages on deposit £10 get free spins and bet £10 get free spins compare the two formats.

How 40 free spins can play out

Forty spins give a slightly fuller picture than a token reward, but they are still a small sample. On a low-volatility slot such as Starburst (published RTP 96.09%, top win 500x), forty spins tend to produce a series of modest returns and rarely anything large; the most a single 10p spin can pay is £50. On a high-volatility slot such as Gates of Olympus (96.50%, up to 5,000x), many more spins return nothing, with a small chance of a bigger payout of up to £500 on a 10p spin.

Neither game changes the average much: about £3.84 against £3.86 over forty 10p spins. What they change is how likely you are to see a total near that figure. Our volatility glossary entry explains the idea in more detail, and free spins maths shows the calculations.

Eligible games and stake limits on 40 free spins

Spins are locked to the eligible games in the terms, usually one slot or a short list of selected games. You can't raise the stake on a free spin, and winnings often have to be used on the same set of games if wagering applies.

Since 2025, online slot spins in Great Britain have been capped at £5 for players aged 25 and over (from 9 April) and £2 for those aged 18 to 24 (from 21 May). That doesn't affect 10p spins, but it does matter for qualifying bets and for wagering on any bonus funds. A bonus's own maximum bet sits on top: Casumo's is £5 per bet, for example. Our page on online slot stake limits has the detail.

A terms checklist for 40 free spins

Before opting in, find each of these in the significant terms. If one is missing, ask support or look elsewhere:

• who can claim (age, location, new or existing customer, sister-brand rules);
• what triggers the spins (deposit, bet, opt-in) and by when;
• which payment methods are excluded;
• the spin value and the named slot or slots;
• how long you have to accept and to use the spins;
• whether winnings are cash or bonus funds, and the wagering multiple;
• any maximum win or maximum conversion.

Casinos must show significant terms up front, close to the offer. Our guide on how to read a significant terms box shows what a good one looks like.

How to claim 40 free spins

1. Check the casino's licence on the Gambling Commission's public register.
2. Read the offer's significant terms and note the trigger, spin value, game and deadlines.
3. Open an account and complete age and identity verification.
4. Set a deposit limit at the prompt before your first deposit.
5. Opt in if required, then deposit, or deposit and bet, with an eligible payment method.
6. Find the spins in the promotions area or open the named slot, and play them before they expire.
7. Check whether the winnings are cash or bonus funds, and withdraw or stop when you choose.

Our how to claim guide covers the process at each partner, and why free spins may not be showing helps if something goes wrong.

How 40 free spins stack up against 80, 100 and 500

PlayOJO's offer is exactly twice a 40-spin bundle and carries no wagering. Our 80 free spins page covers it in depth, and 100 free spins does the same for Coral.

Keeping a 40 free spins bonus in perspective

No bonus makes gambling cheaper over time. Set a budget you're comfortable losing, use the deposit limits and reality checks in your account, and stop when it isn't fun. If you're worried about your gambling, the NHS gambling support pages (opens in a new tab) explain the treatment available, and the National Gambling Helpline is free on 0808 8020 133. Our responsible gambling page lists other services, including GAMSTOP.

Where to play: offers that beat 40 free spins

With no 40-spin offer among our partners, these are the honest alternatives for new customers. All are 18+, all at 10p a spin, and terms apply:

• PlayOJO: 80 free spins on Big Bass Bonanza with a first deposit of £10 or more, worth £8 of play. Whatever the spins win is paid as cash, free of wagering. New UK customers only (not Northern Ireland); can't be combined with other offers. PlayOJO is run by Skill On Net Limited, Gambling Commission account 39326 (opens in a new tab).
• Coral: deposit and bet £10 or more on slots for 100 free spins on selected games (£10 of play). The spins must be accepted inside 48 hours and played within 7 days, and their winnings carry no wagering. Deposits through Neteller, PayPal, Paysafe, Skrill, prepaid cards or certain debit cards are excluded.
• Ladbrokes: deposit and spend £10 on slots for 50 free spins a day over your first 10 days, up to 500 (up to £50 of play). Every daily set has to be claimed by 23:59 and lasts 7 days, with no wagering on what it wins. Deposits by prepaid card, PayPal, Paysafe, Neteller, Skrill or Moneybookers won't trigger it.

PlayOJO is the closest match to a single 40-spin batch, just twice the size. If you'd rather have bonus money than spins, Casumo's casino bonus and 10bet's casino bonus pages cover the match offers compared above.
