What Is the Shamrock Holmes Megaways™ RTP?

RTP is short for ‘Return to Player’, and is basically a calculation of the expected win rate given as a percentage.

The Shamrock Holmes Megaways™ RTP is 96.44%, which is reasonably average and not unusual for a Megaways™ slot game. However, the game itself is highly volatile – with a hit frequency of 35.34% – so you shouldn’t have to wait too long to nail a winning combination.

About the Software Provider

As mentioned previously, Shamrock Holmes Megaways™ was created by Microgaming, one of the biggest software providers in the industry and arguably the first. They are also famed for their Mega Moolah series of progressive jackpot games that have paid out millions of dollars to a few lucky winners.

The Shamrock Holmes Megaways™ Features

Now that you hopefully have a fuller picture of what to expect playing Shamrock Holmes Megaways™, we’ve provided an in-depth guide to all the exciting features and bonus games you’ll find in this slot game.

Rolling Reels


(Source: Microgaming)

This game wouldn’t feature in our Megaways™ slot list without rolling reels, which are activated by any winning combination. The winning symbols are removed from the reels and then replaced by new symbols – the latter can form a winning combination and continue the rolling reels. There is no limit to this feature and can result in big consecutive wins on a single spin.

Magic Forest Re-Spin


(Source: Microgaming)

There are 3 different ways a player can trigger the Shamrock Holmes Megaways™ Magic Forest re-spin. All variations require the Scatter symbol which is a Gold Shamrock – it’s almost like a prize for almost nailing a free spins feature.

This feature only applies during the base game and provides a free re-spin with guaranteed Megaways™. The 3 triggers are:

  • 3 scatters + Leprechaun symbol + Pixie symbol – Free re-spin with 117,649 Megaways™
  • 3 scatters + Leprechaun symbol – Free re-pin with 32,400 Megaways™
  • 3 scatters + Pixie symbol – Free re-spin with 10,000 Megaways™

Shamrock Holmes Megaways™ Free Spins

Land 4 Gold Shamrock Scatter symbols to trigger the free spins feature. You’ll be rewarded with 10 free spins, with each subsequent Scatter adding another 2 free spins to the current tally. As an added bonus, if you happen to hit 6 scatters instead of 4, you’ll be rewarded with 14 initial free spins!

The free spins begin as a 2x multiplier, which means all wins are doubled. However, each rolling reels trigger during the free spins will increase the multiplier by 1. We also confirmed that this is an Unlimited Win Multiplier – much like other Megaways™ slots, there are no limits to the multiplier.

There are no limits to how many free spins you could end up with. 3 Scatters during the free spins will net the player 3 more spins, and 4 Scatters reward the player with another 4 spins too.

The Shamrock Holmes Megaways™ – The Experience

As you probably guessed from its name, the Shamrock Holmes Megaways™ slot is an Irish luck-themed take on the British detective, Sherlock Holmes. It is a theme as old as slot machines themselves, but the leprechaun Shamrock Holmes is a delight. The visuals and animations are quite exceptional, and the gameplay is buttery smooth.

The soundtrack is wonderfully peaceful and serves as the perfect calm before the storm of winning – the longer you play and win, the faster the Irish jig plays! Naturally, it comes as no surprise that a major developer like Microgaming wouldn’t skimp out on the user experience. No matter your device, the Shamrock Holmes Megaways™ slot looks and plays perfectly.

Shamrock Holmes Megaways™ Symbols

You’ll be greeted with some wonderfully fun-looking Irish-themed symbols when playing this game.

While the Ace to Royals are a delightful to look at, they are the lowest-paying symbols of the Shamrock Holmes Megaways™ slot.

The next level of symbols consists of the Pixies symbol, Spring Gentian Flowers, Shamrock Clovers, and the Leprechaun symbol – Shamrock Holmes himself. Shamrock Holmes is the most rewarding of these symbols, offering 1, 2, 10, 25, or 50x your stake depending on which part of the combination it lands.

The Wild symbol in the Shamrock Holmes Megaways™ slot is a W. It only appears above the main reel area and substitutes all other symbols except for the Scatters and re-spin trigger symbols.
