Shamrock Holmes Megaways is an Irish-themed online slot developed by Microgaming in collaboration with All41Studios. The game features the popular Megaways mechanics, offering up to 117,649 ways to win on every spin. The slot was released in December 2020 and has quickly gained popularity among online slot enthusiasts.

The game is set against a backdrop of an enchanted forest and features symbols such as the standard A, K, Q, J, and 10 royals, as well as higher-paying symbols like a pipe, a horseshoe, a pint of Guinness, and of course, Shamrock Holmes himself. The game also features a wild symbol, which substitutes for all other symbols except the scatter.

One of the most exciting features of Shamrock Holmes Megaways is the Rolling Reels mechanic, which is active during both the base game and free spins. Whenever you land a winning combination, the symbols will explode and new symbols will fall into place, potentially creating even more wins.

The game also offers a Free Spins feature, which is triggered by landing four or more scatter symbols anywhere on the reels. Players can earn up to 20 free spins and can also earn additional free spins by landing more scatters during the feature.
