You can never have too many Irish themed slots, and so it is with that spirit that All41 Studios partners with Microgaming to deliver the gaming giant’s first ever Megaways™ release. The trademark 6 reels and top reel return, this time taking on SG Digital’s Rainbow Riches Megaways™ slot in a bid to become the most played Megaways™ slot ever.

Set in an enchanted wood, the Shamrock Holmes of the slot’s title is a leprechaun detective on the hunt for clues. Clues for what exactly? That bit isn’t clear. But the fast-paced action, traditional Irish soundtrack and two bonus features that can see you win up to x28,000 your bet do enough to keep those kinds of questions to a minimum.

Pros & Cons

  • Rolling Reels can award consecutive wins per spin.
  • Maximum Megaways™ guaranteed on Magic Forest Re-Spin.
  • Unlimited incremental win multiplier during Free Spins
  • Only 10 initial free spins awarded.
  • Yet another Irish themed slot.
  • Wilds only appear on the extra reel.

How to Play

In Shamrock Holmes Megaways™ each reel can feature up to seven symbols, with wins awarded for matching symbols adjacently from left to right. Symbols in the extra reel on top of the main reels are added to form winning combinations, which include Wild symbols that substitute for all other symbols except Scatters. Not all Megaways™ slots feature the extra reel, opting instead to include the Megaways™ engine into six reels. To select your bet level press the coin stack beneath the gold spin button.

Once you have chosen your bet press spin, and to change game settings or check the pay table select the relevant icons next to the spin button. In Shamrock Holmes Megaways you must land four Gold Coin Scatters to trigger the bonus game, though you can trigger the Magic Forest Re-Spin by landing a combination of Scatters and symbols on the top reel.

Symbols

It is fitting that Shamrock Holmes, the leprechaun detective of the game’s title, takes his place as the game’s highest paying symbol. He awards x50 your stake for landing six adjacently from left to right, outclassing the Pixie, Shamrock and Flower that pay x5, x2.5 and x2 your respective stake for landing six of a kind. Other high volatility Megaways™ slots like Centurion Megaways™ also feature similar payout structures, with the real chances of big wins coming from the bonus rounds and Rolling Reels™ feature. Rather standard 9s through Aces make up the lower paying symbols that just about keep the game ticking over.

Bonuses

The Shamrock Holmes Megaways™ slot features two bonus games, one triggered by landing four Scatters and the other launched when a combination of Scatters and top reel symbols land together.
