Mango Spins Sister Sites & Full Review

All twelve brands in this network are operated by Grace Media (Gibraltar) Limited of Sovereign Place, 117 Main Street, Gibraltar, GX11 1AA on a single UK Gambling Commission licence, account 57869, licence 057869-R-334655-010. That one licence number carries five activities: bingo and casino from 9 March 2022, gambling software from 14 May 2024, and both general betting activities from 13 June 2025. The register lists 72 domains against the account — 4 Active, 9 White Label and 59 Inactive — and exactly one registered trading name, "grace gaming".

59 of the 72 domains on account 57869 carry status Inactive — 82% of the estate. Counted against the other estates this site has measured from the same export: Betable 6 of 12, Jupiter Gaming 3 of 11, Skill On Net 2 of 60. The Inactive list is not a tail of test domains; it includes complete brands registered twice, once on .co.uk and once on .com — Infinity Casino, Magma Casino, Casino Volcano, Wild Medusa, Tiger Spin, Casino 500 — alongside Chit Chat Bingo, PlayUK, Mayfair Casino, Plush Casino and Panda Bingo. The register publishes status but never the date it changed, so no closure date is claimed for any of them.

The operator names its own network in writing, and the two places it does so disagree. Clause 14.3.1 of the shared terms limits promotions to "one per person, per household, per residential address, per IP address, per device, per payment method, per phone number and per email address, per Site in our Network" — one claim at each of the twelve. The small print on Alfobet's own Halloween free-spins promotion says the opposite: "Can be redeemed once only across Grace Media network". Both were read on 31 October 2026. Nothing here decides which the operator enforces.

The terms are one document wearing twelve badges. Rendered on four brands and compared line by line, 683 of 695 lines are identical. The document is headed "Grace Media Terms and Conditions" rather than the casino's name, and clause 1.1 reads "you enter a binding agreement with Grace Media". The twelve differing lines are a cookie banner, footer link order, two sportsbook-only rows, and the one sentence that names the brand. Two of the four brands compared run the operator's older front end and two run the new one, so both generations serve the same agreement.

Three software suppliers are named across twelve footers. Nine brands say the software is "powered by Grace Media (Gibraltar) Limited" under the same account number the casino itself runs on, which the register supports — a Gambling Software activity has been active on 57869 since 14 May 2024. Chelsea Palace and Red Spins instead name "Markor Technology, licensed and regulated by the UK Gambling Commission (Ref #41645)"; account 41645 is Markor Technology UK Limited and has zero domains registered against it, which is what a pure supplier licence looks like. Fortune Mobile Casino names both in one document — software "powered by Grace Media (Gibraltar) Limited", fairness "monitored in-house by Markor (Gibraltar) Limited experts" — a third version of the supplier's name, and not the one on the register.

oreels.com appears on four UK Gambling Commission accounts at once: White Label on Betable Limited (23328), and Inactive on ProgressPlay Limited (39335), Grace Media (Gibraltar) Limited (57869) and Jupiter Gaming Limited (67098). It is the most-relicensed domain found anywhere in this project. Seven other Grace Media domains also sit on a second licensee's account, including cosmicspins.com, which this site's Betable review lists among that operator's retired domains — it is live here. A white-label brand that changes operator keeps its name, its URL and its marketing and changes its entire sister network, and the register is the only public record of it. No dates are published, so none are claimed.

The shared terms are unusually explicit about an inactive account and unusually long on the clock. An account is inactive after 12 months with no login or gambling activity, at which point the operator undertakes to make contact with instructions for regaining access and states that it charges no inactivity fee. At 24 months the account is closed and "any positive balance will be returned to the last used payment method where possible and lawful to do so", with funds held for later claim if payment cannot be completed. The same document sets no maximum withdrawal per day, week or month; several operators reviewed on this site publish one.

The approved alternative dispute resolution provider is eCOGRA, named in the shared terms with the referral threshold: a complaint unresolved after 8 weeks, or a final response the player is dissatisfied with, can be taken there free of charge. That is the same ADR the Skill On Net estate uses and a different one from Jupiter Gaming, which uses IBAS — worth knowing because a player with accounts on more than one network does not get one adjudicator.

The six brands on the new platform ship the same catalogue, measured rather than compared by eye. Each is a Next.js application that serves its whole lobby in the page payload; decoding that payload yields every game's id, name, provider and type. All six return 1,268 games from three studios — Pragmatic Play 583, Relax Gaming 441, Bragg 244 — and the set difference between any two of them is zero. Three studios for an entire catalogue is narrow: the Jupiter Gaming lobby reviewed on this site carries nine.

All six new-platform brands load their game artwork from one private CloudFront distribution, dfck1euf2k3xu.cloudfront.net, between 4,496 and 4,502 times per homepage. The same six reference gracecasinos.com, a domain that does not appear anywhere on the UKGC register and which redirects to Hot Streak Casino's lobby. Support runs on per-brand Zendesk tenants whose names give the operator away by habit: hotstreakslots.zendesk.com, bettabetuk.zendesk.com, cosmicspins.zendesk.com, alfobet.zendesk.com.

Two of the thirteen live domains are not serving a casino. royalvalleycasino.com, which the register lists as Active, serves only a holding page. casino.redspins.com serves the same page while www.redspins.com stays up and keeps advertising. The wording is identical on both, including its missing word: "Sorry, {brand} is currently unavailable and is moving a new software provider. If you have any remaining balance, or have any other questions related to this move, please reach out to our customer service team." It names no date, no incoming provider, and no outcome for a balance nobody claims.

Four of the twelve brands — Betta Bet, Cosmic Spins, Mango Spins and Rollbit — refuse a browser from outside the United Kingdom, with the message "Access Denied. This site is only accessible in the United Kingdom. Your detected country code: GE. Contact us at customers@thegracemedia.com if you are seeing this in error." Seven others served their full UK build to the same connection in the same session, and Hot Streak served its homepage but blocked its promotions page. Two of the blocked four run the identical platform to two of the unblocked, so the setting is per brand rather than per platform. thegracemedia.com does not appear on the UKGC register.

Unlike every other platform estate reviewed on this site, this one does not run a single welcome offer. Five new-platform brands offer 50 free spins on Big Bass Football Bonanza for a £20 deposit and £20 wager; Alfobet offers 100 free spins on Big Bass Bonanza for the same qualifier, with a £100 redemption cap. Jackpot Mobile Casino offers 20 free spins on Gates of Olympus for £10. Chelsea Palace and Red Spins offer between 100 and 300 bonus spins at 30x wagering with a 4x conversion cap. Fortune Mobile Casino, Fruity Wins and Vegas Wins offer 50 free spins for £20. Three games, two minimum deposits, and spin counts from 20 to 300.

Four brands advertise one offer in the page title and a different one on the page. Jackpot Mobile Casino's title says "Upto £500 Bonus", its body says £500 across three deposits, its FAQ says "£150 plus an extra 150 free spins", and its promotions page gives 20 free spins capped at £50 — while printing the qualifier twice, once as "wager £10" and once as "wager £20", and valuing a spin at £0.20 under a banner that says 10p. Chelsea Palace's title says "Upto £200 Welcome Bonus"; its homepage banner offers a £20 slot bonus for £10, its slots page a 200% match to £50 at 40x, and its promotions banner 300 bonus spins at 30x under a "Deposit £50+" headline whose own small print says £10. Red Spins leads three of its pages with 25 spins for £5 on a game it spells "Big Bash Splash", promises "300 Bonus Spins" in its meta description and "$500" to "international players" in its promotions body. Fruity Wins' title promises 100 spins on Big Bass Splash, its page gives 50 on Big Bass Football Bonanza, and its slots page advertises a package of up to £850 that appears nowhere else. Fortune Mobile Casino's title and page agree.

Every old-platform footer prints two Gibraltar licence numbers in one sentence: RGL No.125 for the operator and RGL No.118 for the software, alongside UKGC account 57869. Fruity Wins prints all three in a single paragraph. A reader checking "the licence number" on these sites has three to choose from and no guidance on which governs their account.

mangospins.com is one of four domains the UKGC register lists with status Active on account 57869, against nine carrying White Label. The brand's own feature data sets casino to true and sportsbook to null, making it casino-only, and its theme data sets a brand primary colour of #0E2438, a secondary of #FEC202 and a navigation background of #5A2080 — the only brand in the estate whose navigation colour appears nowhere else in its palette. Its lobby payload decodes to the same 1,268 games as five sister brands, with a set difference of zero.

Rendered from a non-UK connection on 31 October 2026, mangospins.com returns a full-page block reading "Access Denied. This site is only accessible in the United Kingdom. Your detected country code: GE. Contact us at customers@thegracemedia.com if you are seeing this in error." Betta Bet, Cosmic Spins and Rollbit return the same message. Seven sister brands, including two on the identical platform, served their full UK build to the same connection in the same session. The shared terms name the United Kingdom as the Permitted Jurisdiction and state that geolocation checks require "verification without a VPN".
