Shamrock Holmes is the game’s protagonist. He looks like a cross between Sherlock Holmes and a lucky leprechaun, and he is definitely a cheeky bloke. Alongside him on the reels are a wild W, a gold coin scatter, a cloverleaf, some pixies, and some lovely flowers.

The value of the lower paying card symbols (ranks 9–K) is lower.

Features of the Shamrock Holmes Megaways Slot

There are three main bonus bonuses to enjoy while spinning the reels. The revolving wheels, expanding multipliers, and enchanted respin features.

Gameplay elements such as wilds, respin rounds, and more

There’s a unique spot on the reels for the wild W symbol. It can be used as a substitute for any other icon besides the scatter to complete a winning combination.


The ‘W’ on a square block is the wild icon. It can only be displayed in the screen’s topmost, unused row. When this happens, the wild sign can stand in for any other symbol to complete additional winning combinations.

Spins in the Enchanted Woods

In the bonus game, you can get an endless number of respin triggers. If you obtain a pixie, Holmes, and a scatter all in a row on the same spin, you’ll get a respin. Additionally, it can activate mega ways of up to 177,649, 32,400, or 10,000.

Bonus Spins on Shamrock Holmes’s Megaways Game

Four gold coin scatters anywhere on the screen will launch ten cost-free rounds.

The multiplier begins at 2x on the first free spin and grows by 1x for each subsequent win. Three additional free games are awarded for achieving three more scatters in the first reel.

This is where you can win the incredible 28,000x jackpot, thanks to the feature’s infinite multiplier and re-triggerable free spins.

Visuals and Music

Microgaming really outdid itself with the high-definition visuals and 3D animations. Each icon is bright, bold, and easy to read.

Up until you start spinning the reels, the music is soothing and endearing. The tension builds as you watch the screen in anticipation of the bonus features.
