Slot Summary

An Irish treasure hunt without fixed payline patterns is the niche Rainbow Ray occupies in Endorphina's catalog. The slot follows a rainbow toward a hidden leprechaun village, pairing that familiar pot-of-gold story with wins determined by symbol counts. Repeated tumbles turn the search into a sequence of changing results before the round settles.

How It Plays

Ordinary symbols count wherever they land, with the longest qualifying combination paid for each kind. Winning symbols then disappear, opening space for replacements and another possible payout within the same round.

During free games, Magic Clovers clear ordinary symbols from their row and column after regular payouts. Multiplier and Bonus symbols survive that clearance, while the emptied positions allow further tumbles.

Bonus & Free Spins

Four or more Bonus leprechauns award ten free games. Multipliers ranging from 2x to 100x can land during the feature, but they wait until the winning cascade ends before being added together and applied to its winnings.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (96.12%), 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.
