Rainbow Riches slots are Barcrest's Irish-luck series, launched in 2006 and now owned by Light & Wonder, and they remain some of the most familiar slot names in Britain. This guide compares the three Rainbow Riches games in our checked data, explains why their RTPs can change with your stake, and shows what each costs to play.
Three Rainbow Riches games are in our checked data: the original, Pick 'n' Mix (2016) and Megaways (2019).
The original has a 95.00% RTP, medium volatility and a 500x cap; the Megaways version raises those to 96%, high and 12,500x.
Pick 'n' Mix's RTP runs from about 94% to 96% depending on stake, so check the help screen at the stake you use.
A 2-point RTP gap is worth about £2 per £100 staked on average.
The luck theme is decoration: no leprechaun, pot of gold or rainbow changes the odds.

What the Rainbow Riches slots are
Rainbow Riches is a series of Irish-themed slots from Barcrest, a slot maker with roots in the Manchester area. The first Rainbow Riches arrived in 2006, and the name has since spread across online casinos in several formats. Barcrest itself is now part of Light & Wonder, which bought it in 2011 when the group was still called Scientific Games and which lists Rainbow Riches as its best-known UK slot.
The look is consistent: leprechauns, rainbows, pots of gold and green hills. The maths is not. The three games in our data run from a medium-volatility 20-line game to a high-volatility Megaways title, with top prizes 25 times apart. Our Irish slots page covers other luck-of-the-Irish games, and the full theme list is on our slot themes hub.
6 reels (2–7 symbols) plus a top row, 324 to 117,649 ways
12,500x
The two 20-line games are the classic Rainbow Riches experience: steady, medium volatility and modest caps. The Megaways game is a different animal under the same costume, with bigger swings and a much larger ceiling.
Barcrest and Rainbow Riches: a short timeline
Rainbow Riches makes more sense once you know where Barcrest came from. The company started out making machines for British venues long before online slots existed, as the Barcrest manufacturer record (opens in a new tab) at the International Arcade Museum shows.

That machine heritage shows in the series' feel: simple reels, clear bonus features and, on some titles, RTPs that change with the stake. Our history of slot machines traces how those machines led to online slots.
The original Rainbow Riches slot
Barcrest's first Rainbow Riches uses five reels, three rows and 20 paylines, with a 95.00% RTP, medium volatility and a 500x maximum win. Its appeal has always been its three bonus features, known as Road to Riches, Wishing Well and Pots of Gold, each started by its own symbols. Our bonus rounds guide explains how pick-and-trail features like these work.
A 500x cap is small by modern standards. At 20p a spin, the most the game can pay on one spin is £100, and at £1 it is £500. In return, medium volatility means more frequent smaller wins than the high-cap games on our site, so a budget usually lasts longer. A 95.00% RTP means a 5% house edge: on average, 5p of every £1 staked.
Rainbow Riches Pick 'n' Mix and stake-linked RTP
Rainbow Riches Pick 'n' Mix (2016) keeps the 5x3, 20-line frame and medium volatility, but its RTP isn't a single number. Our checked data gives it as about 94% to 96%, varying with stake. That is a Barcrest habit: the return can differ depending on how much you bet per spin.
500 spins at 20p is exactly £100 staked, so the last two columns match. Across the Pick 'n' Mix range, the difference is about £2 per £100 on average.
Rainbow Riches Megaways: the high-volatility version
Rainbow Riches Megaways (2019) moves the series onto six reels that each show between two and seven symbols, plus a top row. The number of ways changes every spin, from 324 up to 117,649; the top figure is six reels of seven symbols, or 7 x 7 x 7 x 7 x 7 x 7. It has a flat 96% RTP, high volatility and a 12,500x cap.

The higher RTP makes the Megaways game cheaper on average than the original (4p per £1 staked instead of 5p), but the high volatility means rougher sessions. Players who like the classic's steady rhythm may find the Megaways version swingy; those after a bigger ceiling get one, at the cost of longer dry spells.
How to choose a Rainbow Riches game
Decide how much you're happy to spend in the session before opening a game.
If you want steady play and frequent small wins, start with the original or Pick 'n' Mix; if you accept bigger swings for a larger cap, consider the Megaways version.
Open the help screen and read the RTP at the stake you plan to use, especially on Pick 'n' Mix.
Pick a stake that gives you at least 100 spins from your budget.
Set a deposit limit and a reality check, and stop when the budget is gone.
For a comparison outside the series, Lucky Leprechaun from Games Global is another medium-volatility Irish game with 20 paylines, a 96.33% RTP and a 5,000x cap.
Rainbow Riches myths about luck
A series built on four-leaf clovers and pots of gold invites superstition. The maths doesn't care:
Advantages
Fact: each spin's result comes from a random number generator and is independent of the last.
Fact: the RTP is fixed by the game version and, on some Barcrest games, the stake.
Fact: a bonus feature that hasn't appeared for a while is no more likely on the next spin.
Drawbacks
Myth: a game that has just paid a bonus is 'cold' for a while.
Myth: playing at a lucky time or on a lucky day changes the odds.
Myth: chasing a feature with bigger stakes makes it come sooner.
Online Rainbow Riches games follow the Gambling Commission's online slots stake limit guidance (opens in a new tab): £5 per spin at most for players aged 25 and over, and £2 for those aged 18 to 24. They also follow the slot design rules: no autoplay, no turbo or slam-stop, at least 2.5 seconds per spin, and no celebrating returns that don't beat the stake. Our game design rules page sets out each rule with its date.

Frequently asked questions
Who makes Rainbow Riches?
Rainbow Riches is made by Barcrest, a slot maker with roots in the Manchester area that is now owned by Light & Wonder. Light & Wonder bought Barcrest in 2011 under its former name, Scientific Games, and renamed itself in 2022. The series began in 2006. Our Barcrest page covers the studio's history and other games.
What is the RTP of Rainbow Riches?
The original Rainbow Riches has a published RTP of 95.00%, which means a 5% house edge, or 5p of every £1 staked on average over the long run. Rainbow Riches Megaways is 96%, and Pick 'n' Mix runs from about 94% to 96% depending on stake. Always check the help screen for the version you're playing. Our guide to RTP explains what the figure means.
What is the max win on Rainbow Riches?
The original Rainbow Riches has a 500x maximum win, so £100 at 20p a spin or £500 at £1. Rainbow Riches Megaways has a much larger 12,500x cap, worth £2,500 at 20p. The Pick 'n' Mix cap isn't in our checked data, so look at the game's help screen. Our page on what a slot's max win means puts these figures in context.
Why does Rainbow Riches Pick 'n' Mix have different RTPs?
Rainbow Riches Pick 'n' Mix has an RTP of about 94% to 96% that varies with stake, a setup used on several Barcrest games. The game looks the same whichever stake you choose, so the help screen is the only way to see the return at your bet size. The gap is worth about £2 per £100 staked on average. Read our page on whether bigger stakes improve slot RTP for more.
Is Rainbow Riches high volatility?
The original Rainbow Riches and Pick 'n' Mix are rated medium volatility, so wins tend to come more often but smaller. Rainbow Riches Megaways is rated high, with longer dry spells and a far bigger 12,500x cap. If you want a budget to last, the medium games are usually the better fit. Our volatility guide explains how volatility affects a session.
Is Rainbow Riches the same as the pub fruit machine?
No. Online Rainbow Riches games are remote slots licensed separately from the machines found in pubs and arcades, and the rules, stakes and returns differ between the two. Online slots follow the Gambling Commission's remote technical standards, including the £5 and £2 stake limits. Our pages on slots and fruit machines and why online RTPs are higher than in pubs explain the differences.
How many ways to win does Rainbow Riches Megaways have?
Rainbow Riches Megaways has between 324 and 117,649 ways to win, changing every spin. Its six reels each show between two and seven symbols, plus a top row, and the maximum of 117,649 is seven symbols on all six reels multiplied together. Ways pay on adjacent reels from the left rather than on fixed lines. Our Megaways guide explains how the count is worked out.
Does playing Rainbow Riches at certain times improve the odds?
No. Online slots use a random number generator, and every spin is independent, so the time, the day or what happened on the last spin makes no difference. The RTP is set by the game version and, on Pick 'n' Mix, the stake. Our answer to whether slots pay out more at certain times explains why no timing trick works.
