Shamrock Holmes Megaways Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels + up to 117,649 ways to win

Stakes Range: 20p to £20 per spin

RTP: 96.44%

Max Win: 28,500 x bet per spin

The Shamrock Holmes Megaways slot has 6 reels and uses Big Time Gaming’s Megaways mechanic. With between 2 and 7 symbols appearing randomly on each reel, you can play with up to 117,649 ways to win (or Megaways).

The more symbols per reel, the more possible winning combinations. For more details on how the mechanic work, check out our Megaways online slots section. A winning formation is formed by landing 3 to 6 matching symbols on successive reels starting from reel 1. The only exception is Shamrock Holmes himself as you only need 2 on adjacent reels.

When it comes to stake levels, you can spin away from 20p to £20 per spin. Just click on the coins icon on the right hand side of the game to adjust your bet level. There’s an Autoplay function where up to 100 autospins can be chosen. You can play with or without the sound effects and using a Quick Spin mode for faster spin speed.

The Shamrock Holmes Megaways RTP is 96.44% which is over the 96% slot average. This means you will win back £96.44 on average for every £100 you play or wager. Highly volatile, you won’t have to wait long for a winning combination as it comes with a 35.34% hit frequency rate. This means over a third of spins will result in a winner.

When it comes to payouts, the max win is 28,500 x your total bet per spin. Bigger wins will come from the unlimited win multiplier which is in play during the free spins.

Shamrock Holmes Megaways slot base game

The Shamrock Holmes Megaways slot has an Irish luck theme. Set in an enchanted forest, it’s all about the Shamrock Holmes character which combines a lucky leprechaun with the infamous Sherlock Holmes. The soundtrack is calming and peaceful until you press the spin button. The traditional Irish jig gathers pace as you play.

With the symbols appearing on wooden slats, they include Gaelic style A, K, Q, J, 10 and 9 royals. The higher value symbols include Spring Gentian flowers, Shamrock flowers, pixies with cauldrons full of gold coins and Shamrock Holmes. The Shamrock Holmes character is the most rewarding symbol giving you 1, 2, 10, 25 or 50 x your total stake for 2, 3, 4, 5 or 6 in combination.

There is also a W wild symbol which can only appear on the extra reel (above the main reel area). As you can expect, it substitutes for all symbols except the Gold Shamrock Coin Scatter and symbols participating in a re-spin trigger.

Shamrock Holmes Megaways Mobile

shamrock-holmes-megaways-mobile-slot

As with all Games Global (formerly Microgaming) slots these days, Shamrock Holmes Megaways can be played on desktop, mobile and tablet devices as standard. The high definition graphics and animations work well on smartphone screens too. This includes iOS, Android and Windows operating systems.

Shamrock Holmes Megaways Bonus Features

The Shamrock Holmes Megaways slot comes with 3 bonus features in total. You have Rolling Reels for continuous wins, free re-spins with a certain number of guaranteed Megaways and free spins with an unlimited, increasing win multiplier.

Rolling Reels feature

When you get any winning combination, the Rolling Reels feature will be activated. Winning symbols are cleared from the reels and replaced with new symbols. This continues until no more new wins are formed. It can lead to multiple consecutive wins per spin.

Magic Forest Re-Spin feature

There’s a Magic Forest Re-Spin feature which can be triggered in 3 different ways. For all variants, you need 3 gold shamrock coin scatters on the main reels. Then you ned to pixie, leprechaun or pixies plus leprechaun.

Only applying in the base game, this will give you a free re-spin with a certain number of guaranteed Megaways:

Trigger Condition Reward
3 scatters + leprechaun + pixie on extra reel Re-spin with 117,649 guaranteed Megaways
3 scatters + leprechaun on extra reel Re-spin with 32,400 guaranteed Megaways
3 scatters + pixie on extra reel Re-spin with 10,000 guaranteed Megaways

Free Spins feature

shamrock-holmes-megaways-slot-free-spins-feature

Look out for the gold shamrock coins as this is the scatter. 4 gold shamrock coin scatters appearing anywhere on the reels will trigger the Free Spins feature with 10 free spins awarded. Each extra scatter adds 2 more free spins to that tally (i.e. activate with 6 scatters to get 14 free spins).

Beginning with a 2x multiplier, all wins are doubled. Each Rolling Reel trigger increases the multiplier by 1. Like the Unlimited Win Multiplier feature found in many Megaways slots, each win effectively increases the multiplier, with no limits.

Finally, 3 scatters appearing on the extra reel will give you 3 more free spins. 4 scatters will give you 4 more free spins. There’s no limit to how many free spins you can play with.

Originality








The Shamrock Holmes Megaways slot is the first Megaways venture between All41Studios and Games Global. They’ve chosen a popular theme and used popular bonus features to constitute the gameplay. There’s nothing innovative or unique about the gameplay but it does come together rather nice.

Whilst we’ve seen Rolling Reels (Cascading Wins/Reactions), re-spins and free spins with increasing multipliers many times before, the upbeat soundtrack and theme will melt the hearts of most Megaways aficionados. The key to big wins is to build up the multiplier in the Free Spins feature, which has no limits.

With 28,500 x bet max wins, it puts Shamrock Holmes Megaways amongst the highest paying Irish luck themed slots. The UK’s most popular slot, Rainbow Riches, offers you 500 x bet max wins in comparison. Even Rainbow Riches Megaways only comes with 12,500 x bet top payouts.

In summary, Games Global has done a good job with Shamrock Holmes Megaways and I’m sure they will add other features found in popular Games Global slots to future releases.

As far as Megaways slots go, there are better games out there such as Max Megaways and/or Rasputin Megaways (both by Big Time Gaming).

Pros
  • 28,500 x bet max wins
  • High 96.44% RTP rate
  • Microgaming's 1st Megaways slot
Cons
  • Could do with more bonus features
