Shamrock Holmes Megaways Slot (Microgaming)

Shamrock Holmes Megaways Slot (Microgaming)Shamrock Holmes comes in as the very first Megaways slot machine from the gaming giant, Microgaming. This follows their deal with the king of Megaways, Big Time Gaming.

In addition to its great potential, this title offers exciting features, plus very energetic gameplay.

You get to virtually tour the fields of Ireland, and below is the full review of Shamrock Holmes Megaways:

Game Set-Up

It has a typical set up that consists of 6 reels and as many as 117,649 ways to win.

The game’s features are quite interesting, and among them is free spins, Rolling Reels, and increasing multipliers.

Betting and Prizes

The slot’s lowest wagering amount is $0.20 per spin, while the highest amount that you are allowed per spin is $20.

For the top payouts, it’s an open secret that slots using the Megaways mechanism tend to offer very high payouts, and Shamrock Holmes is no exception. The highest payout here is 28,000x the stake.

The high payout is accompanied by high volatility, but Microgaming has provided a fair RTP of 96.44%.

Shamrock Holmes Slot Features

The Megaways mechanism randomly selects the number of symbols per reel. On the 6 reels, each may end up getting between 2 to 7 symbols.

The wilds (W) features will only appear on the horizontal reel located at the top of the middle four columns.

You can form a combo with at least 3 similar symbols appearing on consecutive reels. This should run from the left column, and if done properly, it will trigger the Rolling Reels mechanic.

This will then get rid of the winning symbols, and a new batch of symbols will come in to replace them. It’s a great mechanism that also creates an opportunity for additional wins.  

Scatters will assist you to gain access to the Magic Forest Re-Spins. At this stage, you are guaranteed up to 10,000, 32,400 or 117,649 active Megaways.

You need at least three scatter symbols in view, which work in combination with 1-2 additional symbols of the leprechaun and/or pixie.

With 4+ scatters (Gold Coin), you will get between 10 and 14 free spins. This is where the multiplier will come in, and they start at 2x and increase by 1x each time the Tolling Reels trigger.

Theme & Design

Shamrocks Holmes Megaways doesn’t offer a particularly exciting theme, however, the developer has done extremely well with the design, as well as in the main symbols.

The background does not have the rolling hills of Ireland, but rather, we see a beautiful enchanted forest.

The symbols present on the reels include the W wilds, flowers, fairies, gold coin scatters, flowers, leprechauns, clovers, plus the Royals.


Shamrock Holmes Megaways is a great slot from Microgaming, and I had lots of fun playing it.

However, nothing much is unique, as the slot uses an idea that we have seen before.

It’s a great slot to all level of players particularly if you love the Megaways concept. However, be wary of its high volatility.
