Mathematical Comparison
Mathematics fundamentally determine long-term value and winning prospects.
RTP Analysis
Rainbow Riches: 95% RTP
Fishin’ Frenzy: 96.12% RTP
Winner: Fishin’ Frenzy
Fishin’ Frenzy’s 1.12% RTP advantage translates to approximately £1.12 better returns per £100 wagered long-term. Over extended play, this difference compounds significantly.
Whilst 1.12% seems modest, it represents 23% better value proposition (1.12% / 5% house edge = 22.4% improvement). For serious players, this mathematical edge proves meaningful.
Maximum Win Potential
Rainbow Riches: 500x stake
Fishin’ Frenzy: 5,000x stake
Winner: Fishin’ Frenzy (dramatically)
Fishin’ Frenzy offers 10x greater maximum win potential than Rainbow Riches. A £1 stake offers £500 maximum on Rainbow Riches versus £5,000 on Fishin’ Frenzy—a substantial difference for players seeking meaningful win potential.
Rainbow Riches’ modest 500x ceiling reflects its 2006 origins when slot maximum wins were generally conservative. Fishin’ Frenzy’s 5,000x aligns with modern player expectations around substantial win possibilities.
Volatility Profile
Rainbow Riches: Medium volatility
Fishin’ Frenzy: Medium volatility
Winner: Tie
Both games exhibit similar medium volatility creating balanced experiences with regular small wins punctuated by occasional substantial bonus features. Neither requires extreme bankroll depth nor produces frustrating extended losing streaks typical of high-volatility slots.
This similarity in variance makes direct comparison easier—players comfortable with one game’s swings will generally tolerate the other’s volatility equally well.
Hit Frequency
Rainbow Riches: Approximately 25-30% of spins win
Fishin’ Frenzy: Approximately 20-25% of spins win
Winner: Rainbow Riches (slightly)
Rainbow Riches pays slightly more frequently in base game, creating perception of “luckier” slot despite inferior mathematics overall. More regular small wins sustain bankrolls longer between bonus triggers.
Fishin’ Frenzy’s slightly lower hit frequency concentrates wins more in bonus features, where the game’s strength truly lies.
Feature Comparison
Bonus features create slots’ entertainment value beyond base game spinning.
Rainbow Riches Features
Road to Riches: Spin wheel advancing along path with multipliers up to 500x. Multiple spins build anticipation.
Wishing Well: Pick-me feature revealing instant cash prizes 2x-500x.
Pots of Gold: Spinning pots settle with arrow pointing to bronze/silver/gold multipliers.
Analysis: Three distinct bonus types prevent monotony. However, all are relatively simple pick-and-reveal or wheel-spin formats without complex mechanics. Entertainment comes from variety rather than individual feature depth.
Fishin’ Frenzy Features
Free Spins: Landing 3+ scatter fish triggers 10 free spins. During free spins, any fish symbols landing collect prize values displayed, with fisherman wilds doubling prizes they help collect.
Prize Collection Mechanic: Fish symbols show monetary values (2x-50x) during free spins. Fisherman wilds appearing on same screen collect all visible fish prizes, creating potential for substantial accumulated wins.
Analysis: Single feature type but with more strategic depth than Rainbow Riches’ simpler mechanics. The accumulation and collection system creates tension as fish symbols appear without fishermen, then explosive wins when fishermen finally land collecting everything.
Winner: Fishin’ Frenzy
Whilst Rainbow Riches offers three features versus Fishin’ Frenzy’s one, the fishing game’s feature proves more engaging through its accumulation mechanics. The anticipation of fish appearing followed by fisherman collection creates superior excitement compared to Rainbow Riches’ straightforward reveal/spin bonuses.
Thematic Appeal
Theme preferences prove highly subjective, though cultural context matters.
Rainbow Riches Theme
Aesthetic: Bright, colourful Irish countryside with leprechauns, rainbows, pots of gold, and Celtic imagery.
Cultural Resonance: Irish luck motifs enjoy strong associations with British gambling culture, where phrases like “luck of the Irish” permeate betting vernacular.
Audio: Jaunty Irish folk melodies creating instantly recognisable soundtrack.
Character: The cheerful leprechaun character provides friendly, approachable personality.
Appeal: Broad demographic reach from young adults to older players. Nostalgic associations for those remembering FOBTs’ golden era.
Fishin’ Frenzy Theme
Aesthetic: Nautical/seaside theme with fishing boats, fish, fishermen, and aquatic imagery. Simpler, cleaner visual design than Rainbow Riches’ busy aesthetic.
Cultural Resonance: British seaside and fishing traditions create nostalgic connections for players remembering childhood beach holidays or knowing fishermen.
Audio: Upbeat, bouncy soundtrack without specific cultural associations—more generic but non-irritating.
Character: The cheerful fisherman provides relatable everyman character rather than mythical figure.
Appeal: Similarly broad appeal though perhaps slightly more masculine-coded through fishing associations.
Winner: Subjective (tie)
Theme preference depends entirely on individual taste. Rainbow Riches’ leprechauns versus Fishin’ Frenzy’s fishing theme represent equally valid aesthetic choices with comparable cultural resonance in UK markets.
Graphics and Presentation
Visual quality affects enjoyment, particularly during extended sessions.
Rainbow Riches Visuals
Released in 2006, Rainbow Riches’ graphics reflect that era’s technology limitations. Cartoonish, 2D artwork appears dated compared to contemporary slots, though this contributes to retro charm for some players.
The colourful aesthetic remains appealing despite technical limitations, with clear symbol differentiation and pleasant colour palettes preventing visual fatigue.
Fishin’ Frenzy Visuals
Released in 2014, Fishin’ Frenzy benefits from eight years’ technological advancement over Rainbow Riches. Graphics appear sharper, cleaner, and more polished whilst maintaining accessible cartoon style rather than attempting photorealism.
The seaside theme allows bright blues and greens creating visually pleasant environment without overwhelming complexity.
Winner: Fishin’ Frenzy
Fishin’ Frenzy’s more modern graphics objectively surpass Rainbow Riches’ dated 2006 aesthetics, though Rainbow Riches’ retro presentation holds charm for nostalgic players.

Games prove worthless if players cannot access them easily.

Both games appear at virtually every UK-licensed online casino due to their legendary status and proven player demand. Ladbrokes, William Hill, Coral, 888, PartyCasino, and other major operators feature both prominently.
Land-based availability has declined following 2019 FOBT stake restrictions, though both games remain common in remaining machines.

The Pragmatic Approach
Play both! They’re different enough that playing one doesn’t preclude enjoying the other. Use Rainbow Riches when wanting familiar, simple entertainment with regular small wins. Switch to Fishin’ Frenzy when seeking better mathematics and more engaging features.
Many UK players maintain affection for both games, treating Rainbow Riches as comfortable classic whilst recognising Fishin’ Frenzy’s superior objective qualities.
Final Thoughts
Fishin’ Frenzy wins on mathematics, maximum win potential, and feature engagement—factors serious players prioritise. However, Rainbow Riches’ cultural significance, nostalgia factor, and feature variety create emotional value statistics cannot capture.
For purely entertainment purposes without regard for optimal mathematics, choose whichever theme resonates more. For players caring about RTP, maximum wins, and objective value, Fishin’ Frenzy proves demonstrably superior.
Both games achieved iconic status through quality, accessibility, and cultural timing rather than predatory design or excessive marketing. Neither represents optimal mathematical value compared to 98% RTP alternatives, but both offer honest, engaging entertainment within reasonable variance and house edge parameters.
You cannot go wrong with either choice—they’re both legends for legitimate reasons. But if forced to recommend one objectively, Fishin’ Frenzy’s superior mathematics and engaging features edge out Rainbow Riches’ nostalgic charm and feature variety.
