Rainbow Riches Slot Review — 95% RTP, Three Bonus Rounds

What Rainbow Riches Is

Rainbow Riches is a five-reel, three-row slot from Barcrest, released in 2006 and still one of the most recognisable slot brands in the UK. It runs on twenty fixed paylines with a 95% RTP and medium-to-high volatility.

Its reputation does not rest on the base game, which is deliberately plain — leprechauns, pots of gold and card royals on a green Irish backdrop. What made it a fixture in UK bookmakers and later online is its three separate bonus rounds, each triggered differently and each paying differently. That structure was unusual in 2006 and is the reason the game outlived most of its contemporaries.

The Three Bonus Rounds

Road to Riches is the trail feature: land three or more leprechaun scatters and you spin a wheel to advance along a path of increasing multipliers, stopping when the wheel lands on "collect". The further you get, the larger the multiplier applied to your stake.

Wishing Well triggers on three well symbols. You pick one of the wells and it reveals a multiplier applied to your total bet — a single decision, resolved immediately, with no ladder to climb.

Pots of Gold is the third and most distinctive. Three pot symbols on the middle three reels start a rotating arrow above three pots — gold, silver and bronze — and whichever the arrow stops on determines the multiplier. It is pure chance with no player input, but it is the round most associated with the game.

Three separate features on one machine is the whole design. Compared with a modern slot built around a single free-spins mode with escalating multipliers, Rainbow Riches spreads its variance across three smaller, more frequent events.

How It Compares on RTP

At 95%, Rainbow Riches sits below the modern UK average of roughly 96%. That is typical of its generation — it was designed for a bookmaker cabinet where a lower return was standard, and the online release kept the specification. If payback is your first filter, our ranked list of the highest RTP slots shows what the same stake buys elsewhere, with Blood Suckers at 98% as the outlier.

As always, check the RTP shown in the game's own info panel at your casino before staking. Operators can licence different builds of the same title, and the figure on the page you are playing is the one that governs your session.

The Rainbow Riches Family

Barcrest and its parent Light & Wonder have extended Rainbow Riches into one of the largest slot families in the UK market. The variants share the branding and the leprechaun theme but are genuinely different machines, not reskins:

• Rainbow Riches Pick n Mix — lets you select which of the bonus features are active before you spin, trading one round off against another.
• Rainbow Riches Megaways — rebuilds the game on the Megaways engine, replacing the fixed twenty lines with a reel height that changes every spin.
• Rainbow Riches Free Spins — drops the trail features in favour of a conventional free-spins round.
• Rainbow Riches Cash Cluster — replaces paylines entirely with cluster pays, where wins come from adjacent groups rather than lines.
• Rainbow Riches Even More Pots of Gold — builds the whole machine around the Pots of Gold round rather than treating it as one feature of three.

Because these are separate games with separate specifications, do not assume the 95% figure above carries across the family — each variant publishes its own RTP, and several differ. Check each one in the casino's game info panel.

Playing Rainbow Riches in the UK

Rainbow Riches is a Barcrest title, and Barcrest's distribution among UK-facing casinos is narrower than Microgaming's or Playtech's. Fewer operators carry it, and those that do may stock only part of the family. If a specific variant is what you are after, check the casino's game library before you deposit.

Whichever operator you choose, confirm it holds a current UK Gambling Commission licence on the public register. That licence, not the game studio, is what governs how your funds are held and how disputes are resolved. 18+. T&Cs apply. BeGambleAware.org.
