Theme & Payouts

The setting for this online slot game takes you to the middle of an enchanted woods. That’s where Shamrock Holmes does all his detective work, and he appears on the reels as a symbol with his magnifying glass, too. Prior to any characters and other thematic symbols appearing though, you’ll get to see basic playing card additions from 9 through to A on the six reels.

Next in line is a delicate forest flower as a symbol, before a shamrock can be seen as another. There’s also the addition of a bad fairy, who is trying to steal all the pots of gold in the forest. Yet, it is Shamrock Holmes himself that works as the highest paying standard symbol within the reels of the game. And speaking of high wins, when you spin the reels of the slot, you stand the chance of winning up to 28,000x your stake at a maximum.

While it’s true that there aren’t any other slots that have merged two very different themes together in this way, the Irish theme can be found in various other releases. So, why not try Leprechaun’s Magic Megaways™ from Max Win Gaming? Or as an alternative to that one, there’s Luck o’ the Irish Megaways™, which is a Blueprint Gaming release.


RTP & Volatility 

If you take the decision to play Shamrock Holmes Megaways™, then you’ll be accessing a slot with a high volatility level. This means that you should be prepared to receive higher payouts, but on a less frequent basis. However, at the same time, it does come with an RTP rate of 96.44% included, so this sits nicely above the general average. Therefore, if you are opting to play this game, you can get some great gameplay out of it.

How To Play Shamrock Holmes Megaways™

All41 Studios has made this slot very inviting and approachable, meaning that both experienced and new players can access it with ease. Six reels are in play, with an extra row sitting atop the central four reels. All the buttons that you need can be seen down the right-hand side of the screen, with the bet customisation button being at the bottom of these. Using that, you can select a wager of between €0.20 and €20 per spin.

A wild symbol will also come into play when you spin the reels, but keep in mind that this can only show up on the extra row at the top. When it does though, it will substitute for all other symbols, except for scatters and symbols participating in a re-spin trigger.

Rolling reels are something that feature throughout the game too, and they come into play whenever you form a win. The symbols included in a win will disappear from the reels and then new ones fall into their spaces. Forming additional wins will see this process occur again, and rolling reels can essentially award multiple consecutive wins per spin.

Special Features

Shamrock Holmes Megaways™ also incorporates a couple of special features for you to potentially experience during gameplay. There is a scatter symbol in action, for example. It’s the golden coin with the shamrock on it that operates as this one. Four of them showing up anywhere will activate the game’s 10 free spins round. Every additional scatter beyond those four will add another two free spins on to your total.

Free spins starts out with a win multiplier of 2x in play, and this applies itself to your wins. Each time the rolling reels feature comes into play, the multiplier increases by one. This has no maximum cap that it can reach.

There’s also something known as the Magic Forest Re-Spin in this slot. This occurs whenever three scatter symbols show up as well as Shamrock Holmes and the fairy on the extra reel. The reels go through a re-spin with a guaranteed 117,649 ways to win being in effect for it.


Expert Verdict

Although Shamrock Holmes delivers a nice theme with good gameplay and graphics, the slot offers very little in the shape of new dynamics when it comes to Megaways™. This is however a first outing for Microgaming and All41 Studios, so as their catalogue of games progresses, we hope to see a little more of their own identity stamped upon the the Megaways™ niche.
