Shamrock Holmes Megaways Bonus Features

As a Megaways edition, Shamrock Holmes has all the expected elements of a slot in this category, but it also has a touch of magic in its respin bonus round. There are a couple of special symbols here that could help you win in 10,000, 32,400 or 117,649 different ways guaranteed. But it’s the free spins bonus round that holds the key to some of the game’s biggest wins.


A rainbow-coloured wild operates during both the base game and the free spins round, but it can only appear on the extra horizontal reel. It substitutes for all paying symbols except scatters and the two premium symbols that trigger the respin round.


A gold coin with a lucky clover embossed on it acts as the game’s scatter and triggers the free spins round when 4 or more of them spin into view.

Free Spins

Triggered with golden coin scatters, the free spins bonus round starts with 10 free spins and a 2x multiplier added to your wins. Every additional scatter adds 2 more free spins during this round, and every winning tumble increases the multiplier 1x. There’s no limit to how high the multiplier can increase here. Additionally, landing 3 and 4 scatters on the extra top reel during the round awards 3 and 4 free spins respectively.


The Magic Forest Re-spin feature adds an extra layer of thrills to this Megaways slot when triggered with the right symbol combination. It provides you with a free respin coupled with a high number of guaranteed Megaways.

For example, land 3 scatters on the regular grid, alongside both leprechaun and pixie symbols on the extra reel, and you’ll activate a respin with 117,649 guaranteed Megaways. If you land 3 scatters on the grid together with a leprechaun symbol on the extra reel, you’ll benefit from a respin with 32,400 guaranteed Megaways. Land 3 scatters and a pixie and you’ll enjoy a respin with 10,000 guaranteed Megaways.

Shamrock Holmes Megaways Jackpot

The game’s max payout might not be titled as a jackpot but at 28,000x your stake on a single spin, it certainly deserves that praise. Get those unlimited multipliers rolling, and the max win could be yours for the taking.

RTP and Volatility

The combination of medium-high volatility and a pretty high RTP of 96.44% could work to your advantage when trying to achieve big wins here. But arm yourself with patience and don’t expect them to be very frequent in this game.
