Slot Details

Shamrock Holmes Megaways is a cascading video slot with six dynamic reels, featuring 2 to 7 rows to create 324 to 117,649 ways to win. Pays are awarded for two to six matching symbols landing on adjacent reels from left to right only. You can journey to the Emerald Isle on desktop, mobile and tablet from 0.20 to 20 credits per spin. The game has medium volatility with an RTP of 96.44%.

Loading the game will take you to an enchanted forest on the green isle for a reel quest to find the fabled pot of gold. For once, we do not get the lush realm and rainbow that usually dominate on Irish-themed slot although the main soundtrack is still a traditional tune while Shamrock Holmes and clovers populate the reels.

The pay symbols start at the low end with card royals from 9 through to A, awarding 1x to 1.5x your bet for a single six of a kind. They are followed by purple flowers, green shamrocks, magical pixies and Shamrock Holmes himself. Hit six across the reels to win 2x to 50x your stake. The wild symbol appears in the horizontal reel and performs the usual substitutions duties. Golden shamrock coins act as the scatter, landing on the main reels in the base game and in the top reel during the free spins.

Shamrock Holmes Megaways Slot Features

Late to the party just like a VIP guest would do, Microgaming has finally joined the Megaways community. Playing it safe, they opted for the usual solid gameplay with cascading symbols and a free spins round with the well-known progressive multiplier. There is one extra included in the base game, so let’s don our best Sherlock costume and find out what exactly that is.

As usual, at the core of the gameplay is the Megaways engine under licence from Big Time Gaming where the number of ways from 324 to the maximum is randomly determined for every spin. Each round starts with 2 to 7 symbols dropping onto reels one and six as well as 2 to 6 symbols onto the four middle reels. Additionally, the game has a horizontal extra reel at the top of the game window with four positions, extending from reel two to five, where more symbols appear on every spin.

Scoring any win will trigger the reactive win feature which Microgaming calls Rolling Reels where all symbols from the winning combo will magically disappear to make room for new symbols to drop into place, potentially starting a chain of wins within the same spin sequence. The process is repeated as long as a new winning combination occurs after a cascade.

Teaser spins are one of the most frustrating moments when playing a slot as we just missed a feature trigger or a symbol for a win. Microgaming has turned that around and created a feature out of it that could potentially lead to a mega win. The Magic Forest Respin is free and will activate every time you hit only three scatters in a spin and simultaneously one or both character symbols appear on the horizontal reel. Here’s what you can look forward to:

  • Three Scatters and Pixie symbol: Respin with minimum 10,000 Megaways
  • Three Scatter and Shamrock Holmes symbol: Respin with minimum 32,400 Megaways
  • Three Scatters and Shamrock Holmes + Pixie symbols: Respin with full 117,649 Megaways.

Still, better than a teaser spin is always to actually trigger the bonus feature. On this occasion, you will need to have minimum four coin scatters in view by the time a spin sequence concludes. The game will award 10 Free Spins with every further scatter on the reels adding +2 free spins to the tally. The main kicker for the bonus round is the Unlimited Win Multiplier. It will start at x2 (not a typo) and increase by x1 after every winning reaction, no limits. Landing three or four scatters in the horizontal reel will retrigger +3 and +4 free spins respectively, again, no limits.

Final Verdict

Many of its fans will be justified to ask what took Microgaming so long to release their first Megaways slot. The game engine has proven immensely popular in the player community, propelling it to unmatched success in iGaming. Well, maybe not totally unmatched as we had a similar frenzy years earlier when Microgaming themselves introduced the 243-ways game concept.

As excepted, they played it safe, very safe for that matter as most other licensees have done with their debut. The Magic Forest Respin is a nice touch in the base game while the rest is solid Megaways gameplay with a win potential to match. We are already looking forward to what else they will be cooking up in their slot kitchen.
