Moriarty Megaways Features

There are a variety of features in Moriarty Megaways, but it all begins with the cascading win feature. Ultimately, this means that after you create a winning combination, the winning symbols are removed from the reels and new symbols drop down to replace them.

As the name suggests, this slot comes with the Megaways mechanic which expands the reels to up to 117,649 ways to win during the base game. Each winning cascade actually has an increasing multiplier that grows with each win and resets to x1 after there are no more wins (this is known as Sherlock's Max Megaways).

Watson has mystery symbols that can be randomly triggered on any spin which basically transforms into the same paying symbol it lands next to. There is even a multiplier that starts at x1 and increases with every cascade.

Free Spins

Like most online slots, you can trigger the free spins round of this slot by landing 3 or more scatter symbols on the reels. Naturally, the more scatters you land, then the more free spins you are actually given. Landing 3, 4, 5 or 6 scatters will award 15, 20, 25 or 30 free spins respectively.

Amazingly, the free spins round actually comes with 3 different sets of reels. The main reel is active throughout, but you need to collect 3 Holmes or Watson symbols to open up the Holes and Watson reels. On the Watson reels, you can land newspaper symbols that transform into any symbol except wilds, scatters, Sherlock and Watson.

After unlocking these reels, you get 1 free spin on these reels with the potential to land cascades - but the reels lock after there are no more wins. There is an increasing multiplier that grows with each win (and this includes all 3 of the reels). With all 3 reels active, you can go up to 352,947 ways to win with the 3 different Megaways.

There is an option to buy free spins by paying 150x your stake which increases the RTP, but this isn't available in the UK.

Moriarty Megaways Review

Everyone across the world knows that Moriarty is famously Sherlock Holmes' archenemy and main rival throughout the Arthur Conan Doyle book series. They are two sides of the same coin but remain at odds with each other - which is what makes them so engaging as characters. iSoftBet decided to developer a slot based all around these characters to add to their Twisted Tales series.

Moriarty Megaways plays on 6-reels with 117,649 ways to win with the Megaways mechanic that can actually increase to 352,947 ways to win during the free spins round. There is a mixture of modifiers with features to help you gain wins reaching up to 37,500x your stake.


Set amongst the Victorian streets of London (presumably Baker Street), Moriarty Megaways definitely encompasses a steampunk feeling with cobblestones and Victorian architecture. The sky is dark with particles of dust flying around the screen to really show the grittiness of Victorian England.

As for the symbols on the reels, they are various items relating to the characters such as chess pieces and pocket watches. There's even incredible attention to detail with certain Moriarty wins by dissolved by spiderwebs as Sherlock famously called Moriarty a spider in nature. All of the symbols are beautifully designed and look of a higher quality with so much detailing that you can't help but marvel at them during spins.

The music features cellos, violins and pianos to create a dramatic score that you'd expect to hear in a slot like this. Thankfully, it's not too overwhelming and fits in perfectly - so you can enjoy it without having to worry about where the sound button is. As you spin, you'll hear comments from Sherlock and Moriarty with remarks which add an extra level to this slot.


Despite having the Megaways mechanic, the gameplay still remains quite easy to understand. There are only 6-reels with an extra row above reels 2 to 4 as well as two different sets of reels during free spins which improve the ways to win to 352,947.

Like most iSoftBet slots, you can expect to find the spin button, autospin and bet level just to the right of the reels with additional settings to the left of the screen.

Win Potential

Moriarty Megaways has a good RTP of 96% and a high volatility level. As for the maximum payout, you can expect to see wins reaching up to 37,500x your stake through the free spins round with the ways to win increased to 352,947.

Our Verdict

Not only does this slot look phenomenal, but the gameplay is just as impressive with the Megaways and free spins mechanic. All of the tiny details in the design and audio just make Moriarty Megaways a slot that you can't help but love.

In terms of win potential, you can expect wins of up to 37,500x your stake but be aware of the high volatility. It's simply elementary, that you try out this slot and see if you enjoyed it as much as we did.
