Microgaming’s venture into the Megaways domain, initially patented by Big Time Gaming, marks a significant milestone with the release of Shamrock Holmes Megaways, developed in partnership with All41 Studios. This game represents Microgaming’s initial foray into the Megaways mechanism, showcasing a 6-reel format common in Megaways slots.
Set against an Irish backdrop, Shamrock Holmes Megaways balances the charm of Gaelic culture without being overly stereotypical. The game’s design and soundtrack immerse players in an Irish environment, though the exact narrative behind the protagonist, Shamrock Holmes, remains enigmatic. Playable across various devices, the game caters to a wide range of bettors, with stakes from 20 cents to $20 per spin. The math model underpinning Shamrock Holmes Megaways is robust, featuring a high win potential, medium to high volatility, and an RTP of 96.44%. The game also boasts a high hit frequency of 35.34%, reducing the occurrence of unproductive spins.
The game’s mechanics require aligning three or more matching symbols, with Shamrock Holmes himself being the most valuable, yielding 50 times the stake for six in a line. Other symbols include pixies, clovers, and flowers. The lower-value symbols are represented by 9-A royals with a wooden design. The rainbow ‘W’ serves as the wild symbol, appearing only on the extra reel and substituting for all symbols barring the scatter and respin trigger symbols.
The Megaways feature dynamically alters the symbol count per spin, offering varying win ways. All41 Studios leverages this with the Magic Forest Respins, triggered by specific combinations of scatters and symbols, promising guaranteed Megaways numbers:
Microgaming’s Rolling Reels feature, integral to the game, removes winning symbols and replaces them with new ones, continuing until no new wins occur. The free spins round, activated by landing at least 4 scatters, starts with 10 spins and an initial x2 win multiplier. Each winning combo during free spins increases the multiplier without limit, and additional scatters provide extra spins.
The entrance of both Microgaming and NetEnt, giants in slot development, into the Megaways arena indicates an intriguing phase of innovation and competition. While Red Tiger, a NetEnt partner, chose to revamp Gonzo’s Quest, All41 Studios adopted a more subdued approach with Shamrock Holmes Megaways. The gambling community eagerly anticipates future releases as these titans navigate the Megaways landscape.
