Rainbow Riches is the most recognised slot franchise in UK gambling. Barcrest and its parent Light and Wonder have built an extensive family of variants — and Paddy Power Games carries one of the deepest collections in the UK market. The RTPs across these variants vary by more than 2 percentage points, and the pattern reveals a consistent logic.
Rainbow Riches Cluster Magic: 96.30%
Rainbow Riches Cluster Magic leads at 96.30%. This is the highest-RTP Rainbow Riches variant verified at Paddy Power. It uses a cluster-pays mechanic with high volatility — a newer design that rewards players with a better mathematical return.
Rainbow Riches Megaways: 96.00%
Rainbow Riches Megaways follows at 96.00%. The Megaways mechanic offers up to 117,649 ways to win with high volatility. At 96.00%, it matches industry standard for a Megaways conversion and sits well above the original.
The Original Rainbow Riches: 95.00%
The original Rainbow Riches sits at 95.00%. This is the classic Barcrest 20-payline game with three bonus features — Road to Riches, Wishing Well, and Pots of Gold. At 95.00% it is below the modern average but consistent with its vintage.
The 94.00% Floor: Reels of Gold, Pick'n'Mix, Fortune Favours
Three variants share the 94.00% floor at Paddy Power: Rainbow Riches Reels of Gold, Rainbow Riches Pick'n'Mix, and Rainbow Riches Fortune Favours. These are lower-volatility, feature-heavy games in the classic Barcrest style. The pattern is clear: games with more predictable, frequent payouts carry lower RTPs. Games with higher volatility and less predictable wins carry higher RTPs.
Rainbow Riches Locomotion at Betfair Bingo
Rainbow Riches Locomotion at Betfair Bingo also sits at 94.00%, consistent with the Flutter group's deployment of classic-style Barcrest variants.
How to Choose Between Variants
The heuristic for choosing between Rainbow Riches variants is simple: if you want the best mathematical return, play Cluster Magic or Megaways. If you prefer the classic feature gameplay, understand that you are paying a 1.3 to 2.3 percentage point premium for it. At £1 per spin over 1,000 spins, the difference between Cluster Magic at 96.30% and Pick'n'Mix at 94.00% is approximately £23 in expected losses.
The Broader Lesson
The Rainbow Riches family illustrates a broader principle in the UK slots market: sequel does not mean better, but Megaways or cluster conversion usually does — at least in RTP terms.
