With that, here are the fun bonus features you may come across when spinning the reels on this Irish slot game:

Magic Forest Respin

Want some extra excitement? Trigger the Magic Forest Respin by landing three scatters and specific symbols on the extra reel. It gives you a set number of Megaways, spicing up the base game with surprises. Here’s how it will look:

  • 3 scatters + the pixie symbol on the extra reel = 10,000 Megaways
  • 3 scatters + Shamrock Holmes on the extra reel = 32,400 Megaways
  • 3 scatters + Shamrock Holmes and the pixie on the extra reel = 117,649 Megaways

Rolling Reels

In the heart of the action, there’s the Microgaming Rolling Reels feature. In the Shamrock Holmes Megaways slot, it basically sweeps away the winning symbols on the reels and drops in some brand-new random ones. And get this: it’s not a one-time deal!

This Rolling Reels magic is available all throughout the game, and it keeps on going until no fresh wins pop up. It’s like a reel makeover, always giving you a shot at more wins.

Shamrock Holmes Megaways Free Spins

And now, the sweetest part of Shamrock Holmes—the free spins. This is where the action gets real! So, you gotta get at least 4 scatters anywhere on the reels, and that gets you 10 free spins to start with. But if you see more than 4 scatters, each extra one adds 2 more spins to the party.

Now, here’s the kicker—these free spins kick off with a x2 win multiplier. Every time you land a winning combo, that multiplier goes up by 1. No limits as it just keeps climbing. And if you’re lucky enough to get three scatters on the extra reel, you get an extra 3 free spins. Furthermore, if it’s four scatters, it adds 4 more spins to the mix.

Final Verdict

Shamrock Holmes Megaways is the real deal when it comes to slightly less volatile Megaways slots. With its forest charm, balanced medium volatility, and up to 117,649 winning ways, it’s a winner in our book. Plus, the graphics, music, and bonus features all come together for a seriously fun slot adventure.
