Rainbow Riches Casino casino app: the essentials
Most casinos are named after a company or an idea; this one is named after a game. Rainbow Riches Casino takes its name and Irish-luck theme from Barcrest's long-running Rainbow Riches slots, and the iPhone app is listed as Rainbow Riches Casino & Slots, sold by Gamesys Limited. It needs iOS 16.0 or later on iPhone and iPadOS 16.0 or later on iPad, and the download is about 120 MB.
Behind the branding, the casino runs on Gamesys technology and under a Gamesys licence. As with any UK casino app, the app is simply a way into your online account: the website, the app and any other device you use share the same balance, limits and verification.
A casino named after a slot series
The original Rainbow Riches slot became one of the best-known titles in British bookmakers and online, and Barcrest built a whole series around it, including Rainbow Riches Megaways and Rainbow Riches Pick 'n' Mix. Barcrest is now part of Light & Wonder, which was called Scientific Games when the casino launched in December 2019 as a partnership between the franchise owner and Gamesys.
The App Store description reflects that heritage: it leads with Rainbow Riches titles, then lists other slots, classic casino games and live tables such as blackjack and roulette. The trademark line credits Barcrest Group Limited. You can read more about the studio on our Barcrest provider page.
Gamesys Operations and the wider group
The UK Gambling Commission register lists Gamesys Operations Limited, account 38905, as the licence holder, with the Rainbow Riches domains shown as white labels. A white label means the brand trades under another company's licence; here, Gamesys is responsible for accounts, payments, complaints and safer gambling.
Ownership has moved more than once. Gamesys was bought by Bally's Corporation, and since October 2025 the Gamesys business has been part of Intralot S.A., in which Bally's holds 58%. Gamesys Operations' head office is at Waterport Place, Gibraltar. Other Gamesys brands include Jackpotjoy and Bally Casino, both of which appear on the same licence.

Not mentioned in the listing
The developer's privacy label says identifiers and usage data may be used to track you, and lists financial information, location, contact details, user content, identifiers, usage data and diagnostics as linked to you. Location data is common in casino apps because operators must confirm you are playing from an allowed place. Our casino app privacy settings guide explains how to review these permissions.
Session Reminder and the Wheel O' Riches
Two features named in the listing deserve a closer look. The Session Reminder is a play-time tool that prompts you to take breaks, similar to the reality checks UK licensees must offer. Reminders interrupt play with a message showing how long you have been playing, which helps you notice time passing on a small screen where clocks are easy to ignore.
Open the account menu in the app and find the safer gambling area.
Look for the Session Reminder or reality check setting.
Choose an interval, for example every 30 minutes.
Save it, then add a deposit limit on the same screen if you haven't already.
The Wheel O' Riches is a weekly reward wheel available to members who opt in. Prize types and eligibility rules sit in the app's promotion terms, and any bonus with wagering is capped at 10x for offers made from 19 January 2026. Treat a prize wheel as an occasional extra rather than a reason to log in.
Playing Rainbow Riches slots on your phone
The classic Rainbow Riches game uses a simple five-reel layout that fits a portrait screen comfortably, while Megaways versions with more symbols per reel may be clearer in landscape. Bonus features open as full-screen picks or trails, so turning off notifications during play stops banners covering the buttons. Our guide to portrait vs landscape slots explains how layouts adapt.
UK rules apply to every spin: no autoplay, at least 2.5 seconds per spin, a £5 maximum stake for players aged 25 and over and £2 for 18 to 24-year-olds, and no bonus buy. RTP can differ between casinos because many slots ship in several versions, so open the game's help screen to see the figure in use. Slots carry a house edge, and over time players should expect to lose more than they win.
Installing the app and checking the seller
Search the App Store for Rainbow Riches Casino, then scroll the listing to Information. The seller should read Gamesys Limited and the rating 18+. On Android, look at the developer name in Google Play's About section; if no listing appears, the mobile site works in Chrome. The steps in how to download casino apps apply here too.
Free-to-play social casino apps sometimes feature well-known slot names without any real-money play. They are different products from a licensed casino app, so check the seller and description before downloading.
Gamesys Operations' regulatory record
On 10 January 2024 the Gambling Commission announced a £6,071,292 penalty against Gamesys Operations Limited, along with a required third-party audit of its anti-money laundering and safer gambling controls. The Commission said the company had failed to spot some customers at risk of harm, interacted with them too rarely, and did not carry out adequate checks on some large depositors. The failings occurred between November 2021 and July 2022.
The licence remains active, and the register is the place to confirm its current status.

Frequently asked questions
Who runs the Rainbow Riches Casino app?
Gamesys Operations Limited runs it under UK Gambling Commission account 38905, where the Rainbow Riches domains are listed as white labels. The iPhone app is sold by Gamesys Limited. Gamesys has been part of Intralot S.A. since October 2025, and Bally's Corporation holds 58% of Intralot. The Rainbow Riches name itself belongs to Barcrest, now part of Light & Wonder. Our Jackpotjoy app profile covers a sister Gamesys brand.
Is Rainbow Riches Casino safe to use?
It is licensed by the UK Gambling Commission through Gamesys Operations Limited, so it must verify players, protect funds and data and offer safer gambling tools. The licensee was fined £6,071,292 in January 2024 over safer gambling and anti-money laundering failings, which is part of its public record. Download only the official listing and check its seller. Our casino app safety guide explains what else to look for.
Is Rainbow Riches Casino made by the slot's developer?
Not exactly. The slot series comes from Barcrest, now part of Light & Wonder, which partnered with Gamesys to launch the casino in December 2019. Gamesys runs the casino, its accounts and its licence. The casino's lobby features Rainbow Riches titles alongside games from other studios. Read more about the original game on our Rainbow Riches slot page and the studio on the Barcrest page.
What iPhone do I need for the Rainbow Riches Casino app?
The UK App Store listing requires iOS 16.0 or later on iPhone and iPadOS 16.0 or later on iPad. Phones that can't install iOS 16 won't be able to download the current app, so check Settings, General, About. If your phone is too old, use the website in Safari instead. The app is about 120 MB, so make sure you have space. Our casino apps for older phones guide covers the options.
What is the Session Reminder in Rainbow Riches Casino?
Session Reminder is a play-time tool named in the App Store listing. It shows a message at intervals you choose, reminding you how long you have been playing and prompting a break. It works like the reality checks all UK licensees must offer. Set it from the safer gambling section of the account menu, ideally alongside a deposit limit. Our guide on how to use reality checks explains the setting step by step.
Can I play Rainbow Riches slots for free in the app?
Any demo play in a UK real-money casino requires age verification first, a rule in place since May 2019. Free-to-play social casino apps, which have no real-money play, are different products from a licensed casino app. Check the seller and description before downloading. Our page on casino app demo mode verification explains why demos are locked until checks are done.
Has Gamesys been fined by the Gambling Commission?
Yes. On 10 January 2024 the Commission announced a £6,071,292 penalty against Gamesys Operations Limited, the licensee behind Rainbow Riches Casino, Jackpotjoy and other sites. It also required an independent audit. The Commission found failures in identifying and contacting at-risk customers and in anti-money laundering checks between November 2021 and July 2022. Our UK casino app rules guide explains licensees' duties.
What is the Wheel O' Riches?
The Wheel O' Riches is a weekly reward wheel described on the App Store listing for members who opt in. Prizes and conditions are set out in the promotion terms in the app and can change. If a prize comes with wagering, the cap is 10x for offers made from 19 January 2026. Keep features like this in perspective: they don't change the house edge. Our casino app loyalty rewards page covers similar schemes.
