What is Moriarty Megaways™?

Moriarty Megaways™ slot is the most recent addition to iSoftBet’s exciting games catalogue. Launched on the 19th of May 2021 as part of the “Twisted Tale” series, it proposes a change of optics on the known story of detective Sherlock Holmes.

Unlike other game providers who have made the detective himself the main focus, most notably IGT in “Sherlock Holmes: The Hunt For Blackwood”, iSoftBet decided to flip the narrative and put the lens on professor Moriarty, instead.

Thus, Moriarty Megaways™ slot came to be, showcasing Big Time Gaming’s popular Megaways™ mechanic. It has tons of great features, bonus rounds and two modifiers in the base game – Watson’s Mystery Symbols and Sherlock Max Megaways.

Find all the reasons why you should put this one on your must-try list in our Moriarty Megaways™ review!

Moriarty Megaways™ Mobile Play

Because it is such a new launch and iSoftBet, like other innovative providers, understands the industry’s move towards mobile gambling, Moriarty Megaways™ was designed to play just as well on all devices.

The game’s elements shrink automatically to fit the size of your device, from the menu to the symbols. It plays just as smoothly on a smart-phone with Android or iOS with a landscape orientation or on tablets. All key elements, including the Megaways™ mechanic remain intact so you get the same experience.

Moriarty Megaways™ Top Features

The first aspect that caught our attention when trying out Moriarty Megaways™ is the atypical reel structure – the slot has 6 main reels, plus a horizontal one stretching on top of the 2nd to 5th columns and 2-7 rows.

Because it’s a Megaways™ slot, the number of symbols on each reel changes randomly every round. It starts at 324 and, if you’re lucky, it gets to a maximum of 117 649 in the base game and 352 947 during the free spins feature.

Cascading Wins

A hallmark of the best Megaways™ slots list, this feature couldn’t have been missing from Moriarty Megaways™, either, much to our excitement.

If you can get consecutive matching symbols and form winning combinations with them, the Cascading Reels mechanic gets triggered. Winning symbols will get removed, only to be replaced with new ones that can trigger even more payouts. The mechanic will continue until there are no more winning combinations formed.

You get awarded with a win for 2-6 matching symbols on adjacent reels, starting from left to right.

Free Spins

Free spins are triggered by at least 3 scatter symbols anywhere on the reels. You can unlock between 15-30 extra spins, as such:

The slot keeps the free spins round incredibly lucrative, as both the cascading reels and the increasing multiplier stay active. There is no limit to the value of the multiplier.

During the free spins feature, there are 3 sets of reels to pay attention to – the main one stays active by default, whereas the Holmes and Watson Reels need to be activated by finding at least 3 Holmes and Watson symbols, respectively.

Sherlock Max Megaways™

This is a randomly triggered feature that unlocks the slot’s maximum number of ways to win (117,649). The game offers various modifiers that can come into play during any spin in the base game, expanding the reels to their maximum size. During the Sherlock Max Megaways™ feature, cascading wins and increasing multipliers are also active. The multiplier starts at 1x.

Watson Mystery Symbols

Mystery symbols don’t miss from the best dark-themed, adrenaline-packed detective video slots, and we’re happy to report you can find them here, too.

The Watson Mystery symbols feature does exactly what its name suggests – adds mystery symbols randomly on the reel. You are guaranteed to get at least a winning spin and an increasing multiplier.

Buy the Bonus Feature

Also called the “Moriarty Bet”, this feature essentially gives you a paid ticket to the free spins round.

If you pay 150x your total stake, at least 3 scatters will land on your next spin. Moreover, as opposed to other slots we’ve analyzed on our website, the RTP score will increase, not decrease, from 95.98% to 96.46%, if you buy the bonus. This is a nice touch from iSoftBet and an incentive to make some room in your budget to try this option. At the time of writing, however, the bonus buy feature is not available in the UK.

Theme, Slot Design & User Experience

Moriarty Megaways™ showcases a few connecting themes within the same slot, such as crime & mystery, detective work, fiction and history. The latter is suggested by the Baker Street in the background of the reels, depicted with a Victorian Era feel and the warm, but slightly faded colours that create a Noir atmosphere, even during daylight.

The special symbols are crafted with visual excellence, from the grim outline of professor Moriarty himself, in tune with his role as the villain, to the secondary elements – his golden ring with a precious stone and the A to 9 royals.

The background is reminiscent of 19th century London down to the last detail, from the architecture of the buildings to the vintage street lights, sharing an accurate slice of history with the player.

Lastly, the haunting, eerie soundtrack further enhances the cinematic atmosphere and keeps the player immersed in the world of the anti-hero, Moriarty.

Moriarty Megaways™ RTP, Volatility and Win Potential

Moriarty Megaways™ has an RTP of 95.98%, which can be considered medium to slightly above industry average. The level of volatility is high, so we advise you to tread with caution and be patient for that big payout to occur.

If you play at the maximum bet level, you can win as much as 10 000x your stake or $200 000.

However, if you also unlock the detective symbols (Watson and Holmes), you can win up to 42,553x your stake.

Moriarty Megaways™ Stakes and Betting Range

The betting range for this title is more on the lower end, starting at $0.20, up to a maximum of $20 per spin. Although it fits most players needs, this range might not provide too much excitement to a high roller.

The player objective is very simple and straightforward – land matching symbols on adjacent reels to create winning combinations, starting from reel 1. You can use the ”+” and ”-” options to adjust your bets at any time. The slot also has the popular ”Autospin” feature that you can use if you want to let the game run on its own – you can trigger between 5-1000 automatic spins.

Moriarty Megaways™ – Pros & Cons

Should you or should you not play on the anti-hero’s side in Moriarty Megaways™? That is the question. And here’s our answer:



Moriarty Megaways™ Slot Verdict

Moriarty Megaways™ slot is a very original take on the murder mystery/detective genre. It draws inspiration from both Sir Arthur Conan Doyle’s novels and the cinematic adaptation of the iconic investigator’s adventures, the TV series, “Sherlock”.

Although this slot also includes the private detective, Sherlock Holmes and his trusted help, Doctor Watson, it manages to keep the player focused onto the villain they are trying to defeat, instead – professor Moriarty.

Turned star of the show in Moriarty Megaways™, the anti-hero rewards players with an authentic and highly profitable journey to 19th century London.
