Developed by All41 Studios on behalf of Microgaming, the Shamrock Holmes Megaways slot is a PC and mobile game that stars a leprechaun detective. It’s a 6/7 reel game where you have up to 117,649 ways to line up symbols for a win, and comes with the popular Rolling Reels mechanism that can lead to several wins in a row. You can trigger respins, and there’s a free games feature with an unlimited win multiplier. Prizes in this high volatility game can reach 28,000x your bet, or 560,000.00 if you have the maximum bet on the triggering spin.
A wood-effect grid of symbols floats in the air, surrounded by trees. This is the setting for the Shamrock Holmes Megaways slot machine, which you can visit on PCs, or on mobiles using the Android, iOS, and Windows operating systems at the best mobile casinos. Perhaps the first thing you will notice is that each reel has a different number of symbols on it, and that’s down to the Megaways system, used by All41 Studios under license from Big Time Gaming.
You could see as few as 2 or as many as 7 symbols on a reel at any time, and it gets easier to claim a win with more symbols creating more ways. Those symbols are largely made up of playing card icons, in a vaguely Celtic style, along with flowers, a pixie, clover, and Shamrock Holmes. He’s a cheerful guy in green tweed and a deerstalker hat, holding a magnifying glass.
Gold coins combined with the pixie, Shamrock, or both, trigger respins with a high number of Megaways guaranteed. Rolling Reels can give you win after win, and during a free games feature, a multiplier rises on each Roll in a series. It’s here that you are most likely to land a vast 28,000x your bet at one of the top slots sites.
Like many Megaways slots, the bet range is somewhat limited, with options from 0.20 to 20.00 per spin. You simply click the little stack of coins on the control panel to open up the various bet options, and once you pick a level, you’re ready to play.
The double arrow button activates automatic spins, and the 9 dots tab takes you to the Shamrock Holmes Megaways slot paytable. This reveals how much you win from matching symbols anywhere on adjacent reels from the left side. Shamrock Holmes pays the most, returning 50x your bet for a series of 6 across all reels.
It’s all very easy to manage, and works just as well across the desktop and mobile versions.
A golden ‘W’ can act as others if needed, but only appears on a horizontally-spinning reel above the middle 4 main reels. All symbols in a win will vanish and in a Rolling Reels system new ones drop down to fill the spaces, potentially creating a new win and triggering further rolls, with no limit to how many.
The gold coin with a clover is a scatter symbol, and if 3 land at the same time as the pixie, you get a Magic Forest Respin, with a guaranteed 10,000 ways to win across the reels. If the coins land at the same time as Shamrock Holmes, there’s 32,400 ways in the respin, and if both characters are on the triggering spin, the maximum 117,4649 Megaways are active for a free spin.
Four gold coins trigger 10 free games with an initial 2x multiplier on any win. During this round, the respins can still trigger, and any wins in a Rolling Reels series will activate a multiplier that rises by 1x in each. Once again, there’s no limit to how many Rolls you can trigger, so theoretically, no limit to how high the multiplier can climb.
Despite the theoretical unlimited multipliers, the maximum possible win is set at 28,000x your stake, or 560,000.00 at the 20.00 bet level. Shamrock Holmes Megaways is a high volatility game and there’s an average return to players percentage of 96.44%.
The Irish theme, exciting features, and potential to grab vast win multipliers are just some of the attractions of the Shamrock Holmes Megaways slots game. Rolling Reels are a good way to claim several wins in a row, and the respins with a guaranteed number of Megaways will usually be enough to create a decent win. In the free spins, with rising multipliers, the Rolling Reels become even more valuable.
