About Sherlock Mystery Slot Game

The game is set, but who will play the game and solve the mystery?

If you are one to enjoy a good puzzle, then this game may be for you.

Taking after Sherlock Holmes, the most famous detective of all time, this 5 reel, 20 pay-line video slot game by Playtech Software, will have many a newbie and seasoned player alike captivated.

What is Sherlock without his nemesis, Moriarty? In this game, players will have to chase Moriarty alongside Sherlock for he passes as the game’s wild symbol. The game is littered with wilds, scatters, free spins, and more! Spin-on to find out what else you can get.

The slot includes aspects from the Sherlock franchise to step in as the symbols. Attention to detail is vital when solving a mystery.

The same can be said for the graphics and illustrations of this game. The key is in the details, such as the dusted fingerprints on the letter symbols.

The ever-present Watson can also be seen casually sipping tea on the reels whenever a win is made. Although not the most colourful in terms of theme, sticking only to browns and beiges, this cartoon version of the detective and his sidekick are very welcoming and encouraging.

As in the books, we do not precisely know how Moriarty looks like, so even in the game, he remains a mystery.

So, step into 221 Baker Street and let the games begin!
