Slot Summary

One falling ball can release extra balls, send the game to a Bonus wheel, or add Free Spins before the current spin is finished. Rain Balls turns that pinball-like routing into the defining idea of Skywind Group's Irish slot, with a 96% RTP and high volatility behind the feature hunt. The base reels matter, but the real question is which pot the next ball reaches.

How It Plays

The reel game uses 15 paylines and can Pay Both Ways, so matching combinations may be evaluated from either edge rather than only from the left.

Falling balls add a second layer above that line game. Their destination determines whether the current spin gains extra balls, a Bonus wheel or Free Spins.

Theme & Atmosphere

Rain Balls connects its ball-drop machine to Irish and Lucky imagery, using a Leprechaun, Clover and Rainbow as signs of the available prize routes.

Nature appears through the rain-to-rainbow sequence rather than through landscape detail. The visual idea is simple: the storm releases balls, and each landing may uncover another outcome.

Features & Win Potential

Pay Both Ways broadens the 15-payline base evaluation, while Expanding Wilds can cover additional positions and substitute for regular symbols on qualifying results.

Spin The Wheel opens through the Bonus wheel pot. Its Multiplier outcomes include cash prizes and named bonus values, making the wheel a self-contained result rather than another reel spin.

Bonus & Free Spins

The Free Spins feature starts with 10 spins. Every additional qualifying ball adds two more, allowing the awarded total to increase before the round begins.

The Bonus wheel offers cash Multipliers plus Mini, Major and Grand outcomes. The Grand is listed at x500.00, matching the game's stated maximum win.

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 (96.00%), with wins capped at its top multiplier (500×).

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.
