Shamrock Holmes is a huge deal for the industry, as the first Megaways slot machine to be released by Microgaming, following their deal with Big Time Gaming for this innovative mechanic. With great potential, exciting features and dynamic gameplay, the slot game promises to take us on a trip through Ireland’s fields.

A typical setup with 6 reels & up to 117,649 ways are available for this first release, though Microgaming may surprise us in the future. The game delivers a number of features that should prove interesting, including Rolling Reels, free spins and multipliers which can keep going up forever. Payouts are also well above average for this company’s titles, with wins of 28,000x promised at best, in a slot where RTP is excellent at the 96.44% we’ve seen mentioned.

Betting and Prizes

$0.20 is the starting point for the betting range in this one, and it will go as high as $20 if needed. As you can see, the game has 20 coins to use there, with $0.01 to $1 being the line bet/coin value.

Now, when it comes to payouts, it’s not a surprise that a Megaways slot machine would pay very well, and Shamrock Holmes doesn’t disappoint here. The top jackpot has the potential to reach an excellent value, of up to 28,000x the stake. Having multipliers which can go up infinitely certainly doesn’t hurt.

The downside with these games, is that they have to disappoint a lot of people, in order to be able to pay a few very well. The high volatility is compensated somewhat by the above average RTP, which is expected to be 96.44%.

Shamrock Holmes Slot Features

The Megaways system, which Microgaming is incorporating for the first time, relies on a randomly chosen number of symbols for each of the 6 reels available in this game. 2 to 7 symbols are shown, and the number is chosen at random. A horizontal reel is placed on top of the middle four columns, which is the only place where you will see wild symbols appear. If a round gets 7 symbols on all reels, then you are playing with the full 117,649 ways to win active.

Should a combo form, for which you need 3 or more symbols of the same type on consecutive reels, starting from the leftmost column, the Rolling Reels mechanic will trigger next. The winning positions get removed, others land to take those positions, and additional wins may come, along with more rolls.

A simple W symbol will serve as a wild, and you will only see it land on the horizontal reel.

Via Magic Forest Re-Spins, you can get rounds where there are a guaranteed number of Megaways active (10,000, 32,400 or 117,649). To trigger these, you need three scatter symbols in view, along with 1-2 other symbols (leprechaun and/or pixie) on the horizontal reel.

As for the really good feature, that would involve the free spins. 4+ scatters with the Gold Coin are needed, and in exchange you receive 10 to 14 free spins. You start with an initial multiplier of 2x for all wins, but it will increase in value by 1x whenever the Rolling Reels trigger, following a win. Best of all, they haven’t placed a limit on the multiplier value, so it can all add up quickly during the free spins, particularly since they can be retriggered.

Theme & Design

If we’re looking at the theme alone, it’s not a particularly interesting one, but the design does look very good, and I love the main symbols and the background image of this one. Rather than put us on the rolling hills of Ireland, we’re seeing a beautiful enchanted forest in the background. On the wooden reels, we find the W wilds, gold coin scatters, leprechauns, flowers, clovers, fairies and the Royals (9 to A).


Shamrock Holmes Megaways looks great, and for an initial release from Microgaming it’s not a bad pick to be going with. However, it should be noted that the game’s not going to include much that you haven’t seen before, as only those re-spins are somewhat different from what other Megaways titles include. Even so, those that tend to prefer Microgaming’s casinos will likely enjoy the opportunity to try out more high volatility slots.
