Shamrock Holmes symbols and payouts

Shamrock Holmes comes with six reels and up to 117,649 ways to win (Megaways). Just like in any megaways slot, the number of symbols on each reel changes with every spin, so that the ways to win will vary each and every time.

There’s an additional “bonus” reel that runs across the top of reels 2, 3, 4 and 5. This means that these reels can have up to 8 symbols, whereas reels 1 and 6 can have up to 7 symbols.

Shamrock Holmes Megaways slot depicts an Irish mystical theme with a twist, merging the classic lucky leprechaun with the famous detective Sherlock Holmes. The background is a magic forest where you might expect to find fairies, leprechauns, and mysterious treasures.

Some of the basic symbols in the slot are the Gaelic style letters A, K, Q, J, and the numbers 9 and 10. The higher paying symbols include Shamrock himself, blue flowers, the clover and a fairy with a cauldron of coins. 


Detective Shamrock Holmes is the highest paying symbol in the game, offering 50 times your stake for six of a kind. This is followed by the pixie, clover, and blue flower worth five to two times the bet respectively.

The pixie and its pot of gold pays out 5x, while the four-leaved clover pays 2.5x your stake if you land 6. 

Unfortunately, payouts are low if you land anything less than 5 or 6 symbols of a kind. With regard to the lower-paying card symbols, you’ll almost never get a payout that’s higher than your initial stake.

Shamrock Holmes min/max bets

The minimum bet you can make is CAD0.2, while the maximum is CAD20. This is a reasonable range that caters to both casual and ambitious gamblers alike. 

Shamrock Holmes Megaways Slot RTP, volatility & hit frequency

The Shamrock Holmes RTP comes in at 96.44%, which is above the average. The volatility of the game is rated medium to high. The hit frequency stands at 35.34%, which is again considered to be higher than average. This means out of every three spins, at least one should result in a win.

With some luck on your side, you can win up to 28,000 times your initial bet during the free spins round. This can be achieved thanks to the unlimited win multipliers, but it won’t be an easy feat!

Shamrock Holmes features

The main features in Shamrock Holmes are the free spins, magic forest re-spins and rolling reels. The game also features wild symbols, and an interesting free spins round with an unlimited multiplier! Let’s take a brief look at each feature down below.

Wilds, Respins and other base game features

The W is the wild symbol, which should be easy to remember. Wild symbols substitute for other symbols to create a winning combination. In this game, the wilds only appear in the top bonus reel. The scatter symbol is depicted with clover-engraved gold coins.

Rolling Reels

Rolling reels are an exciting feature that can result in multiple wins from a single spin. All the winning combinations are cleared from the reels and replaced with new symbols. As you keep winning, it’s possible for the reels to keep rolling and netting big payouts. 

Magic Forest Re-Spins

There are three different ways magic forest re-spins can be triggered during the base game.

  • If you land three scatters, with a leprechaun and fairy on the bonus reel will trigger a re-spin with 117,649 guaranteed megaways. 
  • Three scatters with a leprechaun on the bonus reel will trigger a re-spin with 32,400 guaranteed ways to win.
  • Finally, if you get three scatters with a fairy on the bonus reel, it will trigger a re-spin with 10,000 guaranteed megaways. 

Shamrock Holmes Megaways Free Spins

To trigger the free spins round, you need to get four scatters (gold coins) on the reels. Four gold coins on their own will give you ten free spins. Each additional gold coin that appears will add two more free spins to the total.

All free spins start with a 2x bonus multiplier. Each time you trigger a rolling reel on your free spin, the multiplier increases by one, and this can go on indefinitely.

Graphics & Sound

As we’d expect from a recent slot, the crisp graphics are engaging and help to convey the theme well. When you trigger a rolling reel, the winning symbols will light up and then vanish into a cloud of magic, only to be replaced with new symbols. The whimsy forest background adds to the visual appeal and sets the location.

When you’re not spinning, you will hear quiet and soothing background music. As soon as the reels begin rolling, a lively Irish jig will start to play. Overall the graphics are done well, and it’s nice to see those additional details in the backdrop. Everything comes together for an immersive experience.

Other slots to play if you like Shamrock Holmes Slot

If you like the Irish theme, there are certainly many other similar slots you can play. Charms and Clovers also has a similar forest setting and features several of the same symbols. Other popular and recent slots featuring the megaways system include Pragmatic Play’s The Dog House Megaways and Curse of the Werewolf Megaways.

Shamrock Holmes Megaways Slot – Conclusion

Shamrock Holmes proved to be fun to play and delivers an enjoyable experience. Though some of the mechanics (such as the rolling reels) aren’t a groundbreaking feature, the game combines its features in an interesting way that does justice to the theme.

Too often, we see other Irish-themed slots with generic backgrounds with little thought put into the design. Luckily enough, Shamrock Holmes isn’t one of them. If you’re looking for something new to try and you love the megaways game engine, then you can’t go wrong with Shamrock Holmes Megaways.
