Slot Summary

Every win can clear space for another, turning a single stake into a continuing cascade before Rainbow Riches Megaways settles. Barcrest recasts its Irish leprechaun series through six variable reels and as many as 117649 ways, with Mystery Symbols and an expanding Free Spins Multiplier shifting attention from fixed-line bonuses to connected reactions. The 95.9% RTP and high volatility make those extended sequences the game's central source of tension.

How It Plays

Matching symbols pay on adjacent reels from left to right. Winning symbols are removed, new symbols arrive, and the sequence repeats while fresh combinations continue forming.

Variable reel heights determine the available ways on each spin. This makes the initial layout less important than how long its reactions persist after the first win.

Theme & Atmosphere

Irish folklore remains recognizable through the Leprechaun, Rainbow, Lucky horseshoe, pot of gold, and Gems imagery inherited from the wider Rainbow Riches line.

The familiar Mythology setting serves as continuity rather than the main novelty. The altered reel behavior gives the old symbols a faster, less traditional rhythm.

Features & Win Potential

Cascading and Avalanche behavior removes every winning group before replacement symbols arrive, allowing several payouts to develop from one paid spin.

Mystery Symbols can turn the displayed Gems into a shared symbol, while Additional Free Spins and the Free Spins Multiplier increase the value of a sustained bonus sequence.

Bonus & Free Spins

Four Scatter symbols trigger Free Spins. Extra Scatters on the triggering sequence can add more spins, and marked Scatters may award further spins during the feature.

The Free Spins Multiplier rises after successful cascades and does not reset between spins, giving later reactions more weight than comparable base-game wins.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (95.90%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
