Shamrock Holmes Megaways Slot Setup and Controls

As mentioned earlier, the Shamrock Holmes Megaways slot has hundreds of thousands of ways to win. Besides this, it also looks unusual with 6 reels and a special row of symbols sitting upon them. While it may look unorthodox, it is very simple to play even if you’re a beginner to real-money slot sites.

All of the other elements such as the Spin and Autoplay buttons are at their usual spots. The game’s guide is built-in to allow new players to learn the mechanics. You can’t adjust the number of ways to win – they’re set accordingly depending on the symbols that land on the reels.

From a visual perspective, All41 has done great to fit the narrative. The reels are set in a wooden frame against a backdrop of a magical forest. All the symbols are designed nicely, ranging from a leprechaun, golden coins, and flowers to stylized card royals.

All of that is matched by appropriate audio that gives the slot a grounded, yet magical atmosphere.

Shamrock Holmes Megaways Slot Gameplay

To start the unique Holmesian action, you need to set your bets first. Your options go from 0.2 to 20 coins per spin – a pretty solid range for all types of players. Once satisfied, hit the Spin button or set the slot to Autoplay to start spinning. There’s a Quick Spin button too if you don’t want to wait for a full spin.

There are a total of three special features in the Shamrock Holmes Megaways slot game. Two of them apply to the base game. The first one is called Rolling Reels. This is a quite common feature for Megaways titles. Whenever you hit a win, winning symbols are cleared from the reels with new ones taking their place. The feature will stay active as long as there are new winning combinations.

The second feature is called Magic Forest respins. It can be triggered with three different combinations of symbols:

  • 3 Scatters and a pixie on the extra reel
  • 3 Scatters and a leprechaun on the extra reel
  • 3 Scatters, a leprechaun, and a pixie on the extra reel

As you can see, this feature involves the extra reel atop the main reels. The combinations of symbols can trigger the free respin only when they come in addition to three gold coins on the main reels. You’ll get a single respin, but with the guaranteed number of Megaways, leading to massive winning potential.

Shamrock Holmes Megaways Slot Free Spins

The Shamrock Holmes Megaways slot also comes with a Free Spins Round. It is triggered by at least 4 gold coins. You get 10 free spins to begin with, with another gold coin adding 2 more free spins to your tally.

This round begins with an active x2 multiplier. For each Rolling Reel, the multiplier rises by x1. Thanks to this, the Free Spins Round can be pretty lucrative, highlighting the slot’s major winning potential.
