MrQ, Casumo and BetMGM rank as the best slot sites in the UK in 2026, based on our review of 12 UKGC-licensed slot sites and what each one shows you before you sign up.
We checked whether a logged-out visitor can see the RTP on three sample games: Big Bass Splash, Starburst and Fishin’ Frenzy.
We also scored each welcome offer on how fully and fairly its terms are published, and counted the game studios each site lists. The 12 sites below are drawn from our wider list of the best casino sites.
Every RTP figure on this page was read from the operator’s own website on 28 September 2026, and every welcome offer was checked again on 1 October. We have not deposited or played at any of them.

Our review methodology to rank the best slot sites
Each site gets a score out of 10 in three areas. RTP transparency is worth 40% of the total, the welcome offer 30% and the studio list 30%.
- RTP transparency (40%): points for explaining RTP, a figure reachable logged out, a figure on the game page, each sample game with one, and a library-wide figure.
- Welcome offer (30%): every site starts on 5. It gains for full terms, no wagering on spins and a stated no-cap, and loses for deposit-plus-bonus wagering or missing terms.
- Studio list (30%): 100+ studios scores 10, 75+ scores 8, 50+ scores 6, 25+ scores 4, 1+ scores 2. No list reachable logged out scores 1.
The total is (RTP x 0.4) + (offer x 0.3) + (studios x 0.3), rounded to one decimal. Ties go to the higher RTP score, then the most sample games with a figure.
RTP figures were first read on 8 September 2026 and read again on 28 September 2026. Studio counts were checked between 28 and 30 September, and offers again on 1 October. RTPs and offers change, so check before you play.

| 12. Virgin Games | 2.8/10 | Play £10, get 70 free spins | Most time to use free spins |
The rating is the weighted total out of 10. Six of the 12 score 6 or more, and only MrQ passes 8. LuckyMate and BetWright, seventh and eighth here, take the top two places in our list of the best new casino sites.
1. MrQ (8.2/10): Best for no-wagering spins and clear RTP labels
- RTP shown on every sample game page
- No wagering on free spin winnings
-
Licensed in: GB
| MrQ | Key facts |
|---|---|
| UKGC licence | 60629 |
| RTP on game pages | Yes, logged out |
| Sample games with a figure | 3 of 3 |
| Welcome offer | 100 free spins, £10 deposit |
| Wagering | None on spin winnings |
| Studios listed | 25 |
MrQ scores full marks on both RTP transparency and its welcome offer. Its studio list is the one area where it trails.
Score: RTP 10/10, offer 10/10, studios 4/10 = 8.2/10.
MrQ RTP figures and welcome offer
MrQ lists Big Bass Splash at 94.60%, Starburst at 94.05% and Fishin’ Frenzy at 96.12%, each on the game’s own page. The welcome offer is 100 free spins at 10p on Big Bass Splash for a first deposit of £10, used within 48 hours.
Winnings from the spins go straight to your real money balance, so there is nothing to play through before you can withdraw. It’s worth noting the offer is not open to players in Northern Ireland.

Where MrQ leads
MrQ’s promotions page says “Remember, all our promotions are 100% wagering free!” Its offer summary adds that “All winnings are uncapped and credited to your real money balance.”
MrQ’s slots hub also says “the slot with the highest RTP (98.50%) is 1429 Uncharted Seas”. For anyone who wants the best return on their spins, that is a handy place to start.
Where MrQ falls short
MrQ lists 25 studios on its providers page. Casumo, BetMGM, Midnite, LuckyMate and 32Red all list more.
- RTP shown on all three sample game pages
- “No hoops. No wagering on winnings.” on the offer page
- Names its highest-RTP slot: 1429 Uncharted Seas at 98.50%
- 25 studios, fewer than five other sites here
- Spins must be used within 48 hours
- Offer not available in Northern Ireland
2. Casumo (7.7/10): Best for 100+ studios with RTPs shown
- 102 studios in its slots filter
- 10x wagering on the bonus, 7 days
-
Licensed in: GB
| Casumo | Key facts |
|---|---|
| UKGC licence | 61549 |
| RTP on game pages | Yes, logged out |
| Sample games with a figure | 2 of 3 |
| Welcome offer | 50% match up to £100 |
| Wagering | 10x, basis unclear in terms |
| Studios listed | 102 |
Casumo pairs a 102-studio list with a strong RTP score. Its offer is middle of the table.
Score: RTP 8/10, offer 5/10, studios 10/10 = 7.7/10.
Casumo RTP figures and welcome offer
Casumo lists Big Bass Splash at 92.05% and Starburst at 94.05% on their game pages. Our Casumo casino review puts its average RTP at around 93.4% across three titles.
The offer is a 50% match on your first deposit, up to £100. The £20 minimum earns a £10 bonus; the full £100 needs a £200 deposit.
The bonus carries 10x wagering, to be completed within 7 days. Casumo ranks fourth in our best casino bonuses comparison.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2Fcasumo-big-bass-splash-rtp.webp)
Where Casumo leads
Casumo’s slots filter lists 102 studios. It is the only site here that pairs a 100-plus studio list with RTP figures on its game pages. In terms of choice, that goes beyond what is on offer at most other sites here, with only 32Red listing more.
Where Casumo falls short
The offer section says the 10x applies to the bonus. Casumo’s general bonus terms say “Wagering conditions will apply to both the deposited amount and the bonus amount.” Slots with an RTP of 96.8% or higher also count only 30% towards the wagering, so the highest-paying games clear it slowest.
On the full £100 bonus, that is the difference between £1,000 of play and £3,000. Its Fishin’ Frenzy page also shows no RTP and names no provider.
- 102 studios in its slots filter
- RTP figures on game pages a logged-out visitor can open
- 10x wagering and a 7-day window set out in the terms
- No figure on its Fishin’ Frenzy page
- Bonus cash only, no free spins
- Offer terms do not state a maximum win or conversion cap
3. BetMGM (6.7/10): Best for the biggest no-wagering spin count
- 200 spins with no wagering on winnings
- 54 studios listed logged out
-
Licensed in: GB
| BetMGM | Key facts |
|---|---|
| UKGC licence | 39198 |
| RTP on game pages | Some, logged out |
| Sample games with a figure | 1 of 3 |
| Welcome offer | 200 free spins, play £10 |
| Wagering | None on spin winnings |
| Studios listed | 54 |
BetMGM scores well on its offer and a 54-studio list. Its RTP score is held back by two sample games with no figure.
Score: RTP 7/10, offer 7/10, studios 6/10 = 6.7/10.
BetMGM RTP figures and welcome offer
BetMGM’s Fishin’ Frenzy page says it is “a high volatility slot with an RTP of 96.12%”. Its Big Bass Splash and Starburst pages carry no figure. The offer is 200 free spins at 10p on Big Bass Splash when you deposit £10 and wager £10 within 7 days of registering.
You make the deposit through the My Offers page and wager it once. The spins then land in your account at 10p each and expire within 3 days, so they are best claimed when you have time to play.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2Fbetmgm-fishin-frenzy-rtp.webp)
Where BetMGM leads
No other £10 offer on this page gives more than 100 spins. BetMGM gives 200, with no wagering on what they win.
Where BetMGM falls short
BetMGM’s own RTP guide says “By displaying a return to player percentage on each game, casinos like BetMGM demonstrate a commitment to fairness”. Two of its three sample game pages show no percentage.
To be fair, BetMGM is far from silent on RTP. It has a full guide to the subject, and its Fishin’ Frenzy page gives the figure in plain words. It just needs to show the figure on every game page.
- 200 free spins, the most of any £10 offer here
- “There is no wagering requirement attached to any winnings from the Free Spins”
- 54 studios on a providers page you can open logged out
- RTP on only one of three sample game pages
- Spins expire within 3 days of being credited
- Offer terms do not state a maximum win
4. Midnite (6.3/10): Best for RTP figures plus a mid-sized studio list
- RTP shown on every sample game page
- 52 studios on its providers page
-
Licensed in: GB
| Midnite | Key facts |
|---|---|
| UKGC licence | 101839 |
| RTP on game pages | Yes, logged out |
| Sample games with a figure | 3 of 3 |
| Welcome offer | 150 free spins, play £20 |
| Wagering | Not stated in terms |
| Studios listed | 52 |
Midnite shows an RTP on all three sample games and lists 52 studios, but its offer terms leave out the wagering.
Score: RTP 9/10, offer 3/10, studios 6/10 = 6.3/10.
Midnite RTP figures and welcome offer
Midnite lists Big Bass Splash at 94.60%, Starburst at 94.05% and Fishin’ Frenzy at 96.12% on their game pages. The offer behind our link is 150 free spins at 10p on Big Bass Splash. You deposit £20 and wager £20 on Midnite Casino within 14 days of sign-up. Its app ranks seventh in our best casino apps list.
Midnite makes RTP easy to find. Click a slot title and its information page opens with the figure on it. The free spins are valued at 10p each and expire 7 days after they are credited.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2Fmidnite-big-bass-splash-rtp.webp)
Where Midnite leads
Midnite has the most studios of the five sites that show an RTP on all three sample games. Its Big Bass Splash page adds “The RTP supplied for this game is 94.60%.”
Where Midnite falls short
We read Midnite’s offer terms, its general promotion terms and its terms of service to the end. None states a wagering requirement for the welcome spins.
- RTP on all three sample game pages
- 52 studios on a providers page you can open logged out
- 14 days to meet the qualifying spend
- Offer terms do not say whether spin winnings carry wagering
- Terms call the spins “non-withdrawable” but do not say if that covers winnings
- No maximum win stated
5. Grosvenor (6.1/10): Best for detailed RTP information
- RTP shown on every sample game page
- Every offer term published, caps included
-
Licensed in: GB
| Grosvenor | Key facts |
|---|---|
| UKGC licence | 57924 |
| RTP on game pages | Yes, logged out |
| Sample games with a figure | 3 of 3 |
| Welcome offer | £40 bonus plus 100 spins |
| Wagering | 10x deposit plus bonus |
| Studios listed | 12 entries |
Grosvenor scores full marks on RTP transparency, but its offer carries wagering on the deposit and its studio list is short.
Score: RTP 10/10, offer 5/10, studios 2/10 = 6.1/10.
Grosvenor RTP figures and welcome offer
Grosvenor lists Big Bass Splash at 94.60%, Starburst at 96.1% and Fishin’ Frenzy at 96.12% on their game pages. The offer is a £40 bonus plus 100 free spins for a first deposit of £20.
It’s worth knowing that first deposits by PayPal or Paysafe do not qualify, and the bonus can only be played on 18 listed games. The free spins are on Big Bass Splash and must be used within 7 days.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2Fgrosvenor-starburst-rtp.webp)
Where Grosvenor leads
Grosvenor lists Starburst at 96.1%, the highest Starburst figure on this page. It also groups six popular slots it says are “all with RTPs rated over 96%”: Extra Chilli, Eye of Horus, Casino Solitaire, Slingo XXXtreme, Mistress of Egypt and Cash Connection Book of Ra Online.
Where Grosvenor falls short
The terms say “The qualifying Deposit amount (£20) + Bonus (£40) amount needs to be wagered ten times (10x)”. That is £600 of play within 30 days, and free spin winnings carry their own 10x with a £100 cap.
- RTP on all three sample game pages
- Groups popular slots it says are “all with RTPs rated over 96%”
- Every offer term published, including caps
- 10x wagering on deposit plus bonus: £600 in total
- Bonus winnings capped at £200
- 12 entries on its providers page
6. 32Red (6.1/10): Best for the largest free spin bundle
- 320 free spins, the most here
- 114 studios on its providers page
-
Licensed in: GB
| 32Red | Key facts |
|---|---|
| UKGC licence | 45322 |
| RTP on game pages | No, logged out |
| Sample games with a figure | 0 of 3 |
| Welcome offer | 320 free spins, play £30 |
| Wagering | 10x spin winnings |
| Studios listed | 114 |
32Red’s studio list and spin count are among the largest here, but none of its three sample game pages shows an RTP.
Score: RTP 4/10, offer 5/10, studios 10/10 = 6.1/10.
32Red RTP figures and welcome offer
32Red’s Mega Moolah article says “Mega Moolah’s RTP ranges between 88.12% and 93.42%”. Our 32Red casino review found its RTPs on par with MrQ’s across five titles. The offer is 320 free spins at 10p on Big Bass Splash when you deposit and stake £30 on slots, with 10x wagering on spin winnings.
Only deposits by debit card or instant bank transfer count towards the offer. Any winnings from the spins then need to clear the 10x wagering within 30 days.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2F32red-slots-lobby.webp)
Where 32Red leads
32Red lists 114 different studios on its providers page, the most of any site here. It also gives the most spins of any offer.
That openness about its provider library is a big part of why 32Red ranks in the top six despite its low RTP score. A logged-out visitor can see exactly who supplies the games.
Where 32Red falls short
The promo card says spins “expire 30 days after claim”. The terms page says “you have 48 hours to use the spins” and, elsewhere, “Players have 7 days to use their free spins.”
- 320 free spins, the largest spin count here
- 114 studios on its providers page, the most here
- Wagering applies to spin winnings only
- No RTP on any of the three sample game pages
- Terms give conflicting spin expiry windows
- Only debit card or instant bank transfer deposits qualify
7. LuckyMate (5.7/10): Best for low wagering with a stated cap
- 1x wagering on spin winnings
- 33 studios in its search filter
-
Licensed in: GB
| LuckyMate | Key facts |
|---|---|
| UKGC licence | 48789 |

| Sample games with a figure | 0 of 3 |
| Welcome offer | 50 bonus spins, play £10 |
| Wagering | 1x spin winnings |
| Studios listed | 33 |
LuckyMate’s offer terms are complete, but none of the three sample games shows an RTP.
Score: RTP 6/10, offer 7/10, studios 4/10 = 5.7/10.
LuckyMate RTP figures and welcome offer
LuckyMate is not the best here for RTP transparency, but not the worst either. It shows RTP figures on some game pages, such as Sweet Bonanza at 96.48%. The offer is 50 bonus spins at 10p on Big Bass Splash with code MATE50, a £10 deposit and £10 bet on slots within 7 days.
/https%3A%2F%2Fmedia-eurosport.s3.gra.io.cloud.ovh.net%2Fbetting%2F2026%2F10%2Fluckymate-slot-games-lobby.webp)
Where LuckyMate leads
LuckyMate’s offer terms state every key term: 1x wagering on spin winnings, 24 hours to play the spins and “The maximum cashout from Free Spin winnings is £100.”
Where LuckyMate falls short
Big Bass Splash, Starburst and Fishin’ Frenzy all have game pages at LuckyMate, and none of them carries a figure.
You need to enter code MATE50 to get the spins, and once claimed they must be played within 24 hours. Miss that window and they are gone.
- Wagering on spin winnings is 1x
- Every offer term published, including a £100 cashout cap
- 33 studios in a filter you can open logged out
- No RTP on any of the three sample game pages
- Spins must be played within 24 hours
- 50 spins, half what most £10 offers here give
8. BetWright Casino (5.1/10): Best for honest notes on RTP settings
- RTP shown on every sample game page

| Welcome offer | Up to 100 spins, £20 deposit |
| Wagering | Not stated in terms |
| Studios listed | 10 |
BetWright Casino’s RTP labelling is strong, but its offer terms leave out the wagering and its providers page lists 10 studios.
Score: RTP 9/10, offer 3/10, studios 2/10 = 5.1/10.
BetWright Casino RTP figures and welcome offer
BetWright lists Big Bass Splash at 94.6%, Starburst at 94.05% and Fishin’ Frenzy at 96.12%. The offer gives one free spin on Big Bass Splash 1000 for every £0.20 staked on Big Bass Secrets of the Golden Lake, up to 100 spins, after a £20 deposit.
Spins must be claimed within 48 hours of the promotion ending and used within 7 days of claiming. The offer closes at 23:59 on 31 December 2026.

Where BetWright Casino leads
BetWright is the one site here we found telling players that one game can pay back at different rates. “Blueprint supplies this game with several possible RTP settings,” its Fishin’ Frenzy page says. It adds that its own listing shows 96.12%, but to confirm the figure in the game.
Where BetWright Casino falls short
We read the offer page, the general free bet terms and the site terms to the end. None states a wagering requirement or a win cap for the welcome spins.
- RTP on all three sample game pages
- Explains that one game can run at several RTP settings
- Offer runs until 31 December 2026
- Offer terms do not state any wagering
- Spins are on Big Bass Splash 1000, not the base game
- 10 studios on its providers page
9. Boyle Casino (4.8/10): Best for tiered free spins

Boyle Casino shows an RTP on all three sample games, but its offer page gives no wagering figure and we found no studio list.
Score: RTP 9/10, offer 3/10, studios 1/10 = 4.8/10.
Boyle Casino RTP figures and welcome offer
Boyle lists Big Bass Splash at 92.05%, Starburst at 92.05% and Fishin’ Frenzy at 96.12%. The offer gives 20, 50 or 100 free spins at 10p for staking £20, £50 or £100 on slots on the same day, by 23:59.
Boyle shows clear RTP figures on its game pages, which puts it among the better sites here for transparency. The spins arrive the following day before 17:30 and must be used within 72 hours.

Where Boyle Casino leads
Boyle’s offer has three tiers. Staking £20 on slots earns 20 spins, £50 earns 50 and £100 earns the full 100.
Where Boyle Casino falls short
Boyle lists Starburst at 92.05% and Book of Dead at 91.25%. Grosvenor lists the same Starburst game at 96.1%.
- RTP on all three sample game pages
- Spins arrive the next day before 17:30
- Offer runs until 1 December 2026
- Offer page gives no wagering figure or win cap
- Lowest Starburst figure of the sites that show one
- No studio list for a logged-out visitor
10. Coral (4.4/10): Best for RTP guidance in its help centre
- No wagering on free spin winnings

| Wagering | None on spin winnings |
| Studios listed | No filter |
Coral’s offer has no wagering on spin winnings, but we found no game pages a logged-out visitor can open and no studio list. For a big-name brand, it could easily do better on RTP.
Score: RTP 5/10, offer 7/10, studios 1/10 = 4.4/10.
Coral RTP figures and welcome offer
Coral’s Fishin’ Frenzy blog post says “The game’s 96.12% RTP is pretty high compared to similar casino games.” The offer is 100 free spins at 10p when you make a first deposit of £10 and bet £10 on slots. The terms say “There are no wagering requirements for the winnings obtained from the Free Spins.”
The current version of the offer runs until 1 February 2027. Deposits by PayPal, Skrill, Neteller, Paysafe or prepaid card do not count, and your first deposit has to be made after 1 October 2026.

Where Coral leads
Coral’s RTP help page says “You can find the RTP in the help file, or game rules of each game.” That tells a reader where to look, even though its game pages do not open for a logged-out visitor.
Where Coral falls short
Coral has no game pages a logged-out visitor can open, so the only sample figure is Fishin’ Frenzy in a blog post. It also has no studio list we could reach.
- No wagering on free spin winnings
- Help centre explains where to find each game’s RTP
- 48 hours to accept the spins, then 7 days to use them
- No game pages a logged-out visitor can open
- Offer terms do not state a maximum win
- No studio list for a logged-out visitor

Gala Spins has a fair offer, but no sample game shows an RTP and we found no studio list.

Gala Spins RTP figures and welcome offer
Gala publishes RTP figures in some slot reviews: its Knight Rider review says “The RTP of the Knight Rider slot is set perfectly at 96.07%.” The offer is 100 free spins at 10p when you deposit £10 and spend £10 on slots within 7 days of registering.
Once you qualify, you claim the spins from the Promotions section, and they stay valid for 7 days. The same terms cover both Gala Spins and Gala Bingo.

Gala’s spins work on four games: Fishin’ Frenzy, King Kong Cash Even Bigger Bananas, Lock O’ The Irish and Pig Banker 3 Little Piggies. Their winnings “will be credited as cash and will be withdrawable.”
Where Gala Spins falls short
Gala’s Starburst and Big Bass Splash reviews each carry an information box with software, paylines and reels. Neither box has an RTP row.
Without a figure on its game pages, a logged-out visitor cannot easily check the RTP of a slot before playing it.
- “The Free Spins have no wagering requirements.”
- Spins work on four games, including Fishin’ Frenzy
- Winnings are credited as cash
- No RTP on any of the three sample game reviews
- PayPal, Skrill, Paysafe and prepaid card deposits do not qualify
- No studio list for a logged-out visitor

Virgin Games welcome offer
The offer behind our link is 70 free spins at 10p on Game of Thrones when you deposit and wager £10 on slots. The rules say the spins “have no wagering requirements”.
New members have to opt in first. The spins are played at a 1p coin size across 10 lines, which works out at 10p a spin.

Where Virgin Games leads
Virgin gives 30 days from your first deposit to qualify, then 30 more days to play the spins. No other offer here states a longer window.
Where Virgin Games falls short
Its slots page says “Check out the Return to Player (RTP) percentage on individual game pages”. The Big Bass Splash, Starburst and Fishin’ Frenzy pages carry no percentage for a logged-out visitor.
The figures were not visible for any of the three sample games, despite being checked several times in September.
- No wagering on free spin winnings
- 30 days to qualify, then 30 days to play the spins
- Deposit balance and winnings withdrawable during the offer
- No RTP figure a logged-out visitor can reach
- No studio list for a logged-out visitor
- Offer rules do not state a maximum win
What RTP is, and why it differs between sites
RTP stands for return to player. It is the share of all money staked on a slot that the game is set to pay back over millions of spins.
It is a long-run average, not a forecast. A 96% slot can pay back far more or far less than that in one session.
The same game can pay back different amounts
Game studios often supply one slot at several RTP settings, and each site picks one. That is why the same game carries different figures at different sites.
Starburst shows it clearly. Grosvenor lists it at 96.1%, BetWright Casino, Casumo, Midnite and MrQ at 94.05%, and Boyle Casino at 92.05%.
Big Bass Splash splits the same way. Grosvenor, Midnite and MrQ list it at 94.60% and BetWright at 94.6%, while Boyle Casino and Casumo list it at 92.05%.
Where RTP figures can be found
- The game page: the information page a site publishes for each slot. Eight of the 12 sites here use it for at least some games.
- An article or review: a blog post, guide or slot review on the site. 32Red, Coral and Gala Spins keep their reachable figures here.
- Inside the game: the paytable or info panel once a game loads. Coral’s help centre sends readers here.
- Nowhere a logged-out visitor can reach: Virgin Games is the one site here where we found no figure without an account.
Which slot sites show you the RTP
Eleven of the 12 show an RTP somewhere a logged-out visitor can reach, but where they put it varies, from the game page to a blog post or review.
| Site | Where a logged-out visitor finds it | Sample games with a figure | Site-wide figure |
|---|---|---|---|
| 32Red | Article only | 0 | No |
| BetMGM | Game page | 1 | No |
| BetWright Casino | Game page | 3 | No |
| Boyle Casino | Game page | 3 | No |
| Casumo | Game page | 2 | No |
| Coral | Article only | 1 | No |
| Gala Spins | Article only | 0 | No |
| Grosvenor | Game page | 3 | Yes |
| LuckyMate | Game page | 0 | No |
| Midnite | Game page | 3 | No |
| MrQ | Game page | 3 | Yes |
| Virgin Games | Nowhere public | 0 | No |
Coral publishes no game pages a logged-out visitor can open; its one figure sits in a blog post.
Where the figures sit
Eight of the 12 put a figure on the game’s own page. Only five carry one on all three sample games: BetWright Casino, Boyle Casino, Grosvenor, Midnite and MrQ.
Three keep their only reachable figures in articles or reviews: 32Red, Coral and Gala Spins. Gala’s Starburst and Big Bass Splash reviews carry an information box with no RTP row.
Virgin Games is the one site with no figure a logged-out visitor can reach. Its slots page points readers to game pages, and the three sample pages carry no percentage.
LuckyMate’s location reads Game page but its sample count is 0. Both are right: it lists Sweet Bonanza at 96.48%, but none of our three sample games shows a figure.
Where sites fall short of their own words
BetMGM’s RTP guide says “By displaying a return to player percentage on each game, casinos like BetMGM demonstrate a commitment to fairness”. One of its three sample game pages shows one.
Coral has no game pages a logged-out visitor can open. Its help centre tells readers to check the help file or game rules, and one figure appears in a blog post.
Two sites publish an RTP claim beyond single game pages. Grosvenor groups six slots it says are “all with RTPs rated over 96%”, and MrQ names its highest-RTP slot, 1429 Uncharted Seas, at 98.50%.
Six sites show no Starburst figure to a logged-out visitor: 32Red, BetMGM, Coral, Gala Spins, LuckyMate and Virgin Games.

Slot sites FAQs
MrQ, Casumo and BetMGM rank highest on this page, with 8.2, 7.7 and 6.7 out of 10. The scores weigh RTP transparency, welcome offer terms and the size of each site’s studio list.
RTP, or return to player, is the share of money staked that a slot is set to pay back over a very large number of spins. It is a long-run average, not a prediction for one session.
There is no fixed line. On this page, the figures a logged-out visitor could read ranged from 88.12% (the low end of 32Red’s Mega Moolah range) to 98.50% (MrQ’s 1429 Uncharted Seas).
Five sites showed an RTP on all three of our sample game pages: BetWright Casino, Boyle Casino, Grosvenor, Midnite and MrQ. Casumo showed it on two and BetMGM on one.
Start with the game’s page on the site, where many sites list it. If it is not there, open the game and check the paytable or info panel.
No. Grosvenor lists Starburst at 96.1%; BetWright Casino, Casumo, Midnite and MrQ list it at 94.05%; and Boyle Casino lists it at 92.05%.
Slots at UKGC-licensed sites must use game software that has been independently tested. Testing checks that results are random and that the game pays back in line with its stated RTP over time. It does not mean you will win.
Each spin’s result is decided by a random number generator, so no spin is affected by the ones before it.
Over the long run, a slot with a higher RTP pays back more of what is staked than one with a lower RTP. No slot pays out on demand, and one session can go either way.
