There we have the simplest way to play the Sherlock of London slot. Next, let’s find out what the game looks like.

Design and symbols

Sherlock of London has a more steam-punk vibe than other slots that draw from the capers of the world’s most famous detective. The low-value card symbols look mechanical, while Victorian era London lies coated in a spooky mist.

The famous compatriots of Sherlock Holmes make up the higher-value symbols, and these are designed to look cartoonish and friendly. Fans of Sir Arthur Conan Doyle’s work will recognise Irene Adler, Dr Watson, Inspector Lestrade, Moriarty and Sherlock himself. Land five of the symbols representing 221b Baker Street to land the max pay out in the main game of 40x your stake.

The developer behind Sherlock of London is called Rabcat, and they have created other slots with a darker, fictional theme, such as:

Sherlock of London Bonus Spins and Special Features

The Sherlock Holmes symbol in Sherlock of London is the game’s wild symbol, and he appears a lot in the extra features. In fact, he makes three appearances in the following bonus features:

  • Bonus Spins: Land the Sherlock wild on the 1st and 2nd reel simultaneously to win two bonus spins. All wilds will become sticky for the bonus spins. Land more scatters during this round to further your bonus spin count.
  • Connecting Wilds: if a player lands one or more wilds on a spin, the wilds will connect via a pathway, turning any symbols in between into more wilds. This trail can stretch from the very 1st reel to the 5th, transforming all four symbols in its way.
  • Double Win: land two wild symbols on adjacent reels, and all wins on the next spin will be doubled.

The duo of Holmes and Watson come together to create the Sherlock of London scatter. Land this three or more times to receive ten bonus spins. The Dr Watson symbol will become the scatter for the bonus spins, and you can even trigger the connecting wilds and double wins features in this round.

Is this slot worth playing?

The overall design and gameplay in Sherlock of London are fantastic, but there are still some things to keep in mind.

For example, Sherlock of London is a low-stakes slot game. The betting range only allows for a max bet of £25 for a spin, and the max jackpot is only £1,000. There are twenty-five fixed bet ways, as well, which removes one element for new players.

The variance is medium, which can leave players waiting a while for a winning pay line to form. However, the RTP rate is 96.03%, just above the average for slots in 2021. This number suggests that the casino will only have a house edge of 4.97%. Discover more information about the Sherlock of London slot from the table below.
