Shamrock Holmes Megaways Slot

The Megaways slots have taken off, and software providers from all over are jumping to create titles featuring this exciting mechanic.

Industry leader, Microgaming, just joined in releasing their first Megaways slot in collaboration with All41Studios - Shamrock Holmes Megaways.

This thrilling slot game comes with a rather interesting theme, superb graphics and a range of features to keep you entertained with every spin. Of course, it features the Megaways mechanic which unlocks up to 117,649 ways to win.

Theme, Soundtrack and Symbols

Shamrock Holmes Megaways is one slot that can be played throughout the year for thrills and wins. The theme and design also make it perfect for a St. Patrick's Day celebration.

During the design process, Microgaming played on the infamous detective with the leprechaun look and gorgeous natural backdrop. Prepare to search for clues on where the big jackpot lies in a breathtaking, enchanted forest.

On the reels, regular card royals (9 to A) will serve as the low-value symbols. The high-value symbols are all theme-related items, including flowers, leprechauns, clovers and fairies. Special symbols include gold coin scatters and the W – Wild symbol.

The soundtrack is a soothing Irish tune that sets the moods for the duration of the gameplay.

Game Mechanics

Shamrock Holmes Megaways is 6 reels and up to 117,649 ways to win video slot powered by Microgaming. As always Microgaming brings something unique to the table by releasing the first Megaways title in their arsenal. It comes with a range of fun features to be enjoyed with a spectacular theme.

Each spin can be played from as little as €0.20 to a maximum of €20 per spin. You can play on any desktop, tablet or mobile device from anywhere at any time. There is a choice of playing each spin manually or using the auto spin option for up to 100 automated spins. You can also speed up gameplay with the quick spin option.

Shamrock Holmes Megaways is considered a highly volatile slot game with a return to player percentage of 96.44%. While playing, you can trigger maximum wins of up to 28,000x your bet.

Special Features

Shamrock Holmes Megaways boasts a wide range of fun features and winning opportunities starting with the Megaways mechanic. Microgaming truly has created a slot for all fans to enjoy.

The Wild

The wild of the slot is the W, but it will only appear on the extra reel found above the main reels. When it appears, it can substitute for all the symbols apart from the scatters and symbols that take part in the re-spin trigger.

Rolling Reels

Whenever you form a winning combination, the Rolling Reels feature will be activated. During this feature, all winning symbols are cleared from the reels and replaced with a new symbol. This will continue until no new wins can be formed. With Rolling Reels, you can get multiple wins in a row.

Magic Forest Re-Spin Feature

This feature can be triggered 3 ways, but with each, you need 3 gold shamrock coin scatters on the main reels. With the coin scatters you also need a pixie, leprechaun or both to trigger the feature.

The combination used to trigger the re-spin feature will determine the guaranteed Megaways unlocked for the free re-spin.

  • 3 scatters (with a leprechaun and pixie on the extra reel) gets you a re-spin with 117,649 guaranteed Megaways.
  • 3 scatters (with a leprechaun on the extra reel) gets you a re-spin with 32,400 guaranteed Megaways.
  • 3 scatters (with a pixie on the extra reel) gets you a re-spin with 10,000 guaranteed Megaways.

Free Spins

To unlock the free spins feature you need 4 or more gold shamrock coin scatters anywhere on the reels. This will award 10 free spins during which 2 more free spins are added for every extra scatter.

During the free spins, you will start with a 2x multiplier so every win will be doubled. With every Rolling Reel triggered, the multiplier will increase by 1x. Microgaming also incorporates the Unlimited Win Multiplier which means there is no limit to how high the multiplier can go.

If there are 3 scatters on the extra reel, you will receive 3 more free spins, and 4 will get you 4 more free spins. Again, there is no limit placed on free spins, so you can receive an unlimited number of free spins and win multipliers.
