Slots Like Rainbow Riches Megaways: High Volatility Alternatives at 95.90% RTP

Rainbow Riches Megaways takes Barcrest’s most famous Irish-luck brand and bolts it onto a Megaways engine with a sixth horizontal reel, the free-spins multiplier climbs with no upper limit, which is where the big money lives. It runs 6 reels and up to 7 rows for 117,649 ways to win, returns 95.90%, plays at high volatility and tops out at 12,500x stake, and is available to play free or for real money at UK casinos.

Pros and Cons

Reviewed by Brian Taylor
Published: October 2018

Pros

• The free-spins multiplier has no ceiling, it ticks up with every cascade in the round and never resets, so a long chain of tumbling wins is what turns a modest bonus into the 12,500x top prize.
• The extra horizontal reel above the main grid is a genuine point of difference from stock Megaways games: a Rainbow Gem landing up there transforms every gem on the board into one matching colour, which can detonate a huge base-game hit out of nowhere.
• It carries the full Rainbow Riches identity, the jaunty Irish jig, the green fields and the pot of gold, so the brand familiarity from the pubs and arcades is intact for players who grew up with the original.
• The base game sustains a session well thanks to frequent cascade wins, so you are rarely sitting through dead spins waiting for the bonus the way you do on some stingier Megaways titles.

Cons

• The free spins are genuinely hard to trigger, you often need several hundred spins between bonuses, which is a long grind for the feature that holds nearly all the win potential.
• At 95.90% the RTP sits just below the 96% average, and chasing the marginally higher feature-buy figure is poor value over time.
• There is little here to separate it from the dozens of other Megaways slots beyond the brand, mechanically it arrived late and plays it safe.
• High volatility plus a tough bonus trigger means cold runs can be brutal; this is not a slot for a small, cautious bankroll.

How the Game Works

This is a six-reel Megaways game, which means the number of symbols on each reel changes every spin, anywhere from two to seven, so the ways to win flex between 324 and the full 117,649. Wins come from matching symbols on adjacent reels from the leftmost, with no fixed paylines. Every win triggers a cascade: the winning symbols vanish, new ones drop in, and the sequence keeps paying until no new win lands.

What sets this version apart is the fourth, horizontal reel sitting above the four central columns. The Rainbow Gem travels along it, and when a Super Gem lands there it converts all gem symbols on the grid to a single colour, the kind of board-wide transformation that can stack a serious win in the base game, which is rare for the series.

Symbols and Paytable

The paytable is led by coloured gem symbols, with the higher tiers paying best when a cascade or a Super Gem lines several up across the six reels. Below them sit the familiar card-royal symbols (A, K, Q, J) as the low-value fillers. The pot scatter is the key to the bonus, it does not pay directly but triggers the free spins that carry the real value.

Free Spins and the Unlimited Multiplier

Land four pot scatters across the main reels and you trigger 12 free spins, with any extra scatters on the same spin adding more. The headline draw is the win multiplier: it starts at 1x and climbs by one with every single cascade across the whole feature, and crucially it never resets. String together a run of tumbling wins and that multiplier can reach into the dozens, which is precisely how the 12,500x maximum is reached. Scatters landing on the horizontal reel during the feature are marked +1, +2 or +3 and bolt on that many extra spins, with no cap, so a hot bonus can run far longer than the 12 you started with.

The Rainbow Gem and Super Gem

Outside the bonus, the Super Gem is the feature that creates the surprise big wins. When it appears on the overhead reel it sweeps every gem on the board into one matching symbol, and because Megaways wins pay on adjacent reels, a single sweep can turn a quiet screen into a full-board win. It is infrequent, but it is the moment that lifts the base game above a simple wait-for-the-bonus grind.

Similar Slots Worth a Spin

If you enjoy Rainbow Riches Megaways, the closest slots like it stay inside the same Irish-luck family: the original Rainbow Riches for the classic board-game bonuses, Rainbow Cash Pots for a lighter pot-collection take, Rainbow Riches Reels Of Gold for a bigger-reel spin on the brand, and Rainbow Riches Pick n Mix for the version that lets you choose your own bonus.

Rainbow Riches
The 2009 original that started the whole franchise, a 5-reel, 20-line game built around three pick-bonus rounds (Road to Riches, Wishing Well and Pots of Gold) rather than cascades. Its lower volatility and frequent bonuses make it a far gentler ride than the Megaways edition, which is why series veterans often prefer it.

Rainbow Cash Pots
Inspired Gaming’s 2019 leprechaun game runs just 10 lines but pays back a higher 96.50%, with a pot-collection feature at its heart. It is a simpler, friendlier Irish slot than the Megaways title and a sensible pick if 117,649 ways feels like overkill.

Rainbow Riches Reels Of Gold
Barcrest’s 2016 entry uses an unusual variable-height reel set and 100 lines, with a colossal-symbol feature and a 96.00% RTP. It keeps the Irish theme but swaps cascades for big stacked symbols, giving a different rhythm to the Megaways version.

Rainbow Riches Pick ‘n’ Mix
Barcrest’s clever 2016 spin lets you hand-pick which Rainbow Riches bonus features you want active before you spin, on a 20-line, 96.00% RTP base. That player control is the opposite of the Megaways model’s random cascades, and it suits anyone who likes to shape their own session.

What Makes This Slot Tick

The whole appeal here is heritage. Rainbow Riches has been a fixture of UK pub and arcade cabinets since the original launched, and the Megaways edition leans hard on that recognition, the rolling green fields, the rainbow arcing over the pot of gold and the unmistakable Irish jig are lifted straight from the brand players already know.

Mechanically, though, the draw is the Megaways math, not the scenery. The cascading reels keep the base game ticking over and the overhead Super Gem reel is the one feature that feels distinct to this title. If you like games similar to Rainbow Riches Megaways for the leprechaun theme alone, Leprechaun-luck slots such as Lucky Lady’s Charm and Leprechaun Riches share the motif, but they do not share the unlimited-multiplier bonus that defines this one.

Our favourite Rainbow slots

Rainbow Riches Megaways sits among the Irish-luck and rainbow-themed slots, where pots of gold and leprechauns are the recurring motif. Other strong picks include Rainbow Cash Pots, Rainbow Riches Home Sweet Home, the original Rainbow Riches and Rainbow Riches Reels Of Gold.

More Barcrest Slots to Explore

Rainbow Riches is a Barcrest brand, and Barcrest is one of the most recognisable names in British gambling: it began making fruit machines for UK pubs and arcades back in 1968, was bought by IGT in 1998, and now sits within Light & Wonder (the company formerly known as Scientific Games before its 2022 rebrand). Its content reaches UK players through UK Gambling Commission-licensed operators.

That land-based pedigree is exactly why the Rainbow Riches series translates so well online, Barcrest has been refining this Irish-luck formula for decades. Rainbow Riches Megaways is its move to license the Megaways engine for the brand, and it sits alongside other Barcrest and Light & Wonder titles worth a look:

Frequently Asked Questions

What is the RTP and is it variable?

The standard return to player is 95.90%, just below the 96% average. A bonus-buy option nudges it slightly higher, but it is poor value over time, and some operators may run a different configuration, so check the paytable first.

What is the maximum win?

The most you can win is 12,500x your stake in a single spin or free-spins round, which works out at up to £250,000 at the £20 maximum bet. Reaching it depends on the unlimited multiplier climbing high during the bonus.

How do you trigger the free spins?

Land four pot scatter symbols across the main reels to start with 12 free spins. Extra scatters on the triggering spin add more, and during the round scatters on the horizontal reel are marked +1, +2 or +3 to extend it further, with no cap.

Why is the multiplier so important?

The free-spins multiplier rises by one with every cascade and never resets during the round, so a long chain of tumbling wins is the only realistic route to the 12,500x ceiling. The base game alone rarely produces life-changing sums.

Who is the developer?

It is a Barcrest game. Barcrest is a historic British studio founded in 1968, now part of Light & Wonder (formerly Scientific Games), and the originator of the long-running Rainbow Riches series.

What are the best slots like Rainbow Riches Megaways?

For games similar to Rainbow Riches Megaways, stay in the family with the original Rainbow Riches for pick-bonus play, or Rainbow Riches Pick n Mix to choose your own features. If it is the Megaways engine you are after, Montezuma Megaways is another Barcrest take on the same mechanic.

Is it worth playing if I liked the original Rainbow Riches?

It depends what you liked. If it was the cheerful theme and the pick bonuses, the original is gentler and pays them out more often. If you want bigger top-end potential and do not mind a harder bonus trigger, the Megaways version offers far more volatility and a much higher ceiling.

Our Verdict on Rainbow Riches Megaways

Rainbow Riches Megaways is for the player who loves the Irish-luck brand and wants the bigger, spikier potential the Megaways engine brings, the unlimited free-spins multiplier and the overhead Super Gem are real highlights. It is not for cautious or small-bankroll players: the bonus is hard to land, the volatility is high and the 95.90% RTP is unremarkable. If you like slots like Rainbow Riches Megaways but want a softer ride, the original Rainbow Riches or Rainbow Cash Pots are kinder; if you simply want a strong Megaways, plenty of rivals do it with more invention. Played sensibly it is a polished, familiar spin on a much-loved brand. 18+ only; please gamble responsibly.
