Slot Summary

Five reels rise through six rows in Rainbow Rush, Slotmill's Irish-folklore slot in which the height of a rainbow matters to the result. Its cheerful leprechaun setting accompanies a high-volatility design: expanding wilds bring both wider coverage and multipliers, putting the emphasis on what a rainbow reaches when it appears.

Features & Win Potential

Ordinary Rainbow Wilds extend downward from their landing position, converting covered spaces into wild symbols. Their multiplier increases as they grow, reaching as high as x6.

Golden Expanding Wilds extend in both directions instead of only downward. That distinction changes which positions they can cover, making the wild variant important alongside its landing location.

Free Spins Multiplier Scatter Symbol Wild Symbol Wild Multipliers 5 Reels Additional Free Spins Expanding Symbols RTP range Bonus Bet Random multiplier

Bonus & Free Spins

Golden Pots Free Spins increases the frequency of Rainbow Wilds. Super Free Spins replaces all Rainbow Wilds with the golden version, applying the bidirectional expansion rule throughout that feature.

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 (95.20%), with wins capped at its top multiplier (12,000×).

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.
