Rainbow Riches is the original Irish-luck slot from Barcrest — the game that launched a series of 25-plus titles. This page sets out the plain facts: what it is, how it plays, its RTP, and how the bonus features work — without hype.

It is written to inform, not to promote. Nothing here recommends playing or depositing. Slots are games of chance built with a house edge, so over time they are designed to return less than is staked.

The Three Bonus Features
Road to Riches
Triggered by three or more leprechaun symbols. A spinner moves you along a trail of rising multipliers; you collect the value where you stop, and landing “Collect” ends the round. This is the feature that can climb toward the top prize.
Wishing Well
Triggered by three Wishing Well symbols. You pick one well to reveal a stake multiplier. It’s the simplest of the three and generally the lowest-paying.
Pots of Gold
A wheel points to one of three pots (bronze, silver or gold), each carrying a different multiplier. The gold pot holds the biggest single award and is the most likely route to the 500× ceiling. A gold-coin wild also substitutes in the base game.
Keep the ceiling in perspective
The maximum win is 500× your stake — small next to modern slots that reach thousands of times the bet. The RTP stays the same whatever your bet size or number of active lines, so betting more or “playing all lines” only changes how much you stake, not your long-run odds.

What It Is

Rainbow Riches is a video slot from Barcrest, now part of Light & Wonder. It first appeared as a land-based machine in 2006 and moved online around 2009, becoming a fixture of UK pubs and arcades before its digital versions spread worldwide. It runs on a 5-reel, 3-row grid with 20 paylines and a cheerful Irish-luck theme — a leprechaun mascot, pots of gold and rainbows.

A note on the series: Rainbow Riches now spans more than 25 games, including Megaways, Pick ‘n’ Mix, Drops of Gold and the Rainbow Riches Cash Cluster version. Their numbers and mechanics differ from title to title — this page covers the original classic, so check which one you’re playing.

How It Plays

Set your bet (from around $0.20 up to a high per-spin maximum) and spin; wins pay for matching symbols across the 20 lines from the left. The base game is straightforward — the real character comes from the three bonus features, each with its own trigger symbol, which makes a session feel like a series of small events rather than a build-up to one round.

RTP, Volatility and Max Win

The RTP is around 95%, which is slightly below the industry average of roughly 96%, though operator versions can differ — check the live figure on the game’s information panel. Our guide to RTP explained covers what that means in practice.

The volatility is medium, so you’ll see a mix of smaller wins without huge swings. The most important number to be realistic about is the maximum win: 500× your stake. That’s modest by modern standards — many newer slots reach thousands of times the bet — and it’s only reachable through the bonus features, most often the gold pot in Pots of Gold. This is a classic, gentle game rather than a big-win chaser, which is worth knowing before you play. Importantly, the RTP stays the same regardless of your bet size or how many lines you play, so betting more never improves your odds — it only increases what you stake.

Playing From New Zealand

You’ll find Rainbow Riches at online casinos that carry Light & Wonder / Barcrest titles and accept New Zealanders. Rather than naming specific sites, the important thing is to check the operator itself: the legal backdrop changed in 2026, when the Online Casino Gambling Act 2026 created New Zealand’s first licensing system for online casinos, run by the Department of Internal Affairs (DIA). From 1 December 2026, only DIA-licensed operators may lawfully offer online casino games to New Zealanders. Our overview of online casino licensing in New Zealand explains how that works, and you can browse more titles via our casino games section.

Practical Notes (Not a Strategy)

No strategy changes a slot’s odds — every spin is independent and random, and a bonus is never “due,” however long the wait. A few honest pointers specific to this game: the RTP is slightly below average, so it’s a touch more expensive over time than a 96%+ slot; the 500× ceiling is modest, so keep expectations grounded; playing all 20 lines doesn’t improve your odds — it just raises your stake; try the demo/free-play mode first; and set a firm time and money limit before you start. Our casino bonuses guide explains the wagering fine print.

Staying in Control: Responsible Play in Aotearoa

A friendly, familiar theme and frequent little bonus rounds can make it easy to keep spinning without noticing time or spend adding up. Treat any slot as paid entertainment only — never as a way to make money or recover losses. Regulated operators must provide control tools such as deposit limits, reality checks and self-exclusion. Our guide to self-exclusion tools explains how they work.
