Rainbow Riches Slot Review
Rainbow Riches is the slot that put Barcrest on the map with UK players. Originally a land-based machine in pubs and arcades from 2006, it moved online in 2009 and has stayed in casino lobbies ever since. Barcrest is now part of Light and Wonder (previously SG Gaming), but the game itself has changed very little - five reels, 20 paylines, an Irish luck theme, and three separate bonus features that each work differently. That variety in the bonus round is what keeps people coming back to a game that, on paper, looks quite basic.
This review covers exactly how each bonus works, what the RTP means for your session, and how the original compares to the 20+ sequels the franchise has produced.
Rainbow Riches at a Glance
- Developer: Barcrest (Light and Wonder)
- Released: 2009 (online); 2006 (land-based)
- Reels / Rows: 5 x 3
- Paylines: 20 fixed
- RTP: 95.00%
- Volatility: Low to medium
- Max win: 500x stake
- Bet range: £0.20 - £400 per spin
- Hit frequency: 27.02% (roughly one win per 3.7 spins)
- Bonus features: Road to Riches, Wishing Well, Pots of Gold
The 95% RTP sits below the online average of around 96%, which is worth knowing before you sit down for a long session. It does not make the game unplayable, but it does mean the maths slightly favour the house more than most comparable slots. Low-to-medium volatility softens the impact - you will land wins fairly often, even if the amounts stay modest for long stretches.
Theme and Design
The Irish luck theme is thorough without being overdone. Shamrocks, leprechauns, wishing wells, pots of gold, and the rainbow itself fill the reels against a vivid green landscape backdrop. The visual style is cheerful and deliberately simple - no animated sequences between spins, no complex layering. The leprechaun character appears at key moments, particularly when a bonus triggers.
For a game that launched in 2009, the graphics have aged better than you might expect on mobile. The clean art style and flat icons read well at smaller screen sizes in a way that some more detailed contemporaries do not. The soundtrack is upbeat Irish folk, which can become repetitive across longer sessions but fits the theme.
The reels carry four scatter symbols - the leprechaun, the wishing well, and the pots of gold each trigger their own separate bonus. The gold coin acts as a wild, substituting for all standard paying symbols.
How Paylines Work
Rainbow Riches uses 20 fixed paylines across a 5x3 grid. You cannot adjust the number of active lines - all 20 pay on every spin. Wins form left to right from the first reel. The minimum bet per spin is £0.20, which covers all 20 lines at £0.01 per line. At the maximum end, £400 per spin makes this accessible at both low and high stakes.
The Three Bonus Features
Road to Riches
Road to Riches is the most talked-about of the three features and the one that appears most often in session play. It triggers when three or more leprechaun scatter symbols land anywhere on the reels.
When it fires, a wheel appears and you spin it. The wheel determines how many steps the leprechaun moves along a golden multiplier trail. The trail runs from 1x at the start up to 500x at the end. Your win is whatever multiplier the leprechaun lands on when the wheel shows "Collect". The wheel can show Continue - moving the leprechaun further along - or Collect, which ends the feature and pays the multiplier at the leprechaun's current position.
The tension comes from knowing you could collect a 5x multiplier or, with the right sequence of Continue spins, push all the way to 500x. Most sessions see a payout in the lower-middle range of the trail. Reaching the 500x end requires a specific run of Continue results, which is rare but not impossible.
Wishing Well
The Wishing Well feature triggers when three or more wishing well symbols land anywhere on the reels. You are then presented with the wishing wells and asked to pick one. Each well hides a multiplier. The win is your stake multiplied by whatever the chosen well reveals, ranging from 2x up to 500x.
It is a single pick-and-reveal mechanic - no continuation, no secondary choice. The simplicity makes it quick to resolve, but it lacks the drawn-out suspense of Road to Riches. Whether it pays a handful of times your stake or a significant amount is down to which well you pick.
Pots of Gold
Pots of Gold triggers when three pot symbols land simultaneously on reels 2, 3, and 4. The screen shows three pots - bronze, silver, and gold - spinning in a circle. When they stop, the pot facing an arrow determines your prize. Gold pots pay the highest values, bronze the lowest, with silver in the middle.
The spinning presentation is where the leprechaun animation comes in most prominently. This feature resolves quickly and has a clear ceiling - no trail to advance along, no picks to make. The entertainment sits in watching the pots slow down.
RTP and Volatility in Practice
The 95% RTP is the main criticism levelled at Rainbow Riches, and it is a fair one. In a market where most modern slots sit at 96-97%, a 95% return is a notable disadvantage over extended play. The gap between 95% and 96% may seem small, but across thousands of spins it represents a meaningful difference in expected return.
That said, Rainbow Riches Pick'n'Mix - one of the more recent variants in the franchise - offers a variable RTP between 94% and 98% depending on which bonus features the player selects, which is a more player-friendly approach if RTP matters to you.
Low-to-medium volatility keeps the session experience steady. Wins land roughly once every 3.7 spins on average, which means the balance does not drop sharply between bonus triggers. Most wins in the base game are small - typically between 2x and 10x your line stake - with the larger payouts concentrated in the bonus features. It is not a game that will deliver many big base-game hits, but it does keep the reels interesting between features.
Mobile Play
Rainbow Riches runs on HTML5 and works in any modern mobile browser. The 5x3 grid adapts well to portrait orientation on phones - the symbols are clear, the bonus presentations scale without cutting off, and the bet controls are accessible. Given the age of the game, it loads quickly compared to more visually complex modern titles. There is no dedicated app to download; any casino that offers it will load it directly in the browser.
The Rainbow Riches Franchise
The original game sparked one of the most expansive slot franchises in the UK market. Light and Wonder's Barcrest studio has produced more than 20 Rainbow Riches titles since 2009. Notable entries include:
- Rainbow Riches Megaways - uses Big Time Gaming's Megaways engine, 96% RTP, max win of 12,500x
- Rainbow Riches Pick'n'Mix - lets players choose which bonus features to activate, variable RTP up to 98%
- Rainbow Riches Free Spins - adds a traditional free spins round to the base format
- Rainbow Riches Drops of Gold - introduces a cluster-pays mechanic
- Rainbow Riches Leapin' Leprechauns - adds jumping wilds to the base game
- Rainbow Riches Road to Even More Riches - released August 2025, expanding the Road to Riches mechanic
If the 95% RTP of the original puts you off, the Megaways version and Pick'n'Mix are the two most straightforward upgrades. Both keep the Irish theme and recognisable bonus concepts while offering better returns and higher win potential.
Similar Games Worth Playing
If the Irish luck theme appeals, several related slots are worth considering:
- Lucky Leprechaun - Microgaming's take on the leprechaun theme, featuring a pick-me bonus and free spins
- Clover Rollover - NextGen title with a similar Irish aesthetic and a free spins round
- Leprechaun Goes to Hell - Play'n GO's darker twist on the theme with a high volatility profile
- High RTP slots - if the 95% RTP is a concern, this list covers slots consistently above 97%
Verdict
Rainbow Riches works because its three bonus features each feel different. Road to Riches gives you a trail with genuine tension as you decide whether you have pushed far enough. Wishing Well gives you a quick pick. Pots of Gold gives you a visual spin. Three distinct experiences within one base game is more interesting than most slots that launch a single free spins feature every time. The 95% RTP is a genuine drawback and worth knowing about, but it has not stopped the game from remaining in UK casino lobbies for over 15 years. If you want better maths with the same formula, the Megaways version is the sensible choice. If you want the original experience that started the franchise, the classic is still widely available.
