Slot Summary

A guaranteed number of winning ways changes the stakes of a respin in Shamrock Holmes Megaways. All For One Studios combines that interruption to the changing reel field with a leprechaun detective whose name echoes Sherlock Holmes. The Irish fantasy treatment stays playful, while the distinction between ordinary spins, special respins and multiplier-bearing free spins defines the pacing.

How It Plays

Regular combinations run across adjacent reels from the left, without requiring symbols to share a row. The extra horizontal reel contributes symbols above the middle of the main field.

Rolling Reels removes winning combinations after payment and lets other symbols shift into the empty spaces. Further combinations repeat that process without requiring another paid spin to begin.

Theme & Atmosphere

The title character combines a leprechaun with detective styling, drawing on the name and identity of Sherlock Holmes. That crossover gives the Irish setting a recognizable comic lead.

A magical forest surrounds the case, with pixies, clovers and flowers reinforcing the fantasy atmosphere. These references keep the detective premise within folklore rather than presenting a realistic criminal investigation.

Bonus & Free Spins

Four scatters trigger 10 free spins, with additional triggering scatters adding more spins. Winning cascades increase the bonus multiplier, which carries through losing spins. Further scatter appearances during the feature can extend the remaining allowance.

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 (96.44%), with wins capped at its top multiplier (28,000×).

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.
