How to play Sherlock of London

As with the vast majority of modern video slots, Sherlock of London has a clean, user-friendly interface which is standard across all devices: mobiles, tablets and desktops.

The game has 25 fixed paylines. Therefore, all you need to set before spinning is how much you want to bet each round. This ranges from £/€0.25 up to £/€50.00. Joining Sherlock on the reels are his able companion Dr Watson, 221b Baker Street sign, Inspector Lestrade, Irene Adler and Moriarty. There are also several low-valued symbols represented by decorative numbers and letters.

Sherlock Holmes is the Wild. He is also the joint highest-value symbol alongside the Baker Street sign. When you land five of those of on a payline, you get 1,000x your line bet. There is also a special symbol of Holmes and Watson together that triggers the exciting free spins bonus round.

Wilds: the key to big Sherlock of London wins

Wilds are commonplace with most slots but Sherlock of London really pushes the boat out and uses them to full effect. These are the features using Wilds:

  • Connecting Wilds - if more than one Wild appears on the reels and they are not next to one another, the Wilds will be connected with all symbols on the path also turning Wild. This can lead to some stellar wins, particularly if the Connecting Wilds are on the 1st and 5th reels
  • Double Win Wild - when exactly two Wilds land on the reels and they are side-by-side, they will merge to form the Double Win feature. At this point, all winning combinations from the spin will have a 2x multiplier
  • Bonus Spins Wild - if only one Wild lands on either the 1st or 2nd reel, one or two respins will be activated. The Wild is locked in place during these respins. If on the first respin, you get a Connecting Wild or Double Win Wild, you do not receive the second respin

Free spins bonus Round

Land three or more Holmes & Watson scatter symbols in the base game and you unlocked the bonus feature which starts off as 10 Free Spins. These can be retriggered multiple times during the round if you land three scatters again.

Both the Connecting Wilds and the Double Win Wild feature are present with the free spins. However, the Bonus Spin Wild is replaced by an Expanding Wild feature which covers the whole reel.

If that’s not enough, the Dr Watson symbol becomes an Extra Wild throughout the feature. All this Wild action results in some magnificent bonus wins, especially when you consider these symbols pay up to 1,000x your line bet.

Rabcat really is one of the hottest names in the industry at the moment because the quality of its games is absolutely top drawer. Sherlock of London is guaranteed to entertain everyone. Whether you were previously a fan of London’s greatest super sleuth or not.

This slot has an RTP value of 96.03% which is competitive but not outstanding.

It is a medium variance slot, so it spits out enough small wins to avoid your bankroll being wiped-out too quickly. Castle Builder II is another amazing slot by Rabcat. We recommend trying both of these titles if you haven’t done so yet.
