Here’s what else you can expect…

Theme, Graphics & Soundtrack

Explore the streets of Victorian-era London at nightfall and join legendary detective Sherlock Holmes as he solves crimes and tracks down notorious villains. The reels are set against a Victorian building and illuminated by the warm glow of a street light, which creates a slightly eerie atmosphere.

The game’s main soundtrack is both mysterious and intriguing, which clearly suits the overall theme perfectly. The sound of horses and carriages trundling down cobble-stoned streets can also be heard, which further helps to set the scene. The reels make a whooshing sound when they are in motion and an additional soundtrack plays as each reel clicks into place, which heightens the anticipation even more.

As you will come to expect from Mobilots free play slots, the quality of the animations is excellent and every element functions seamlessly to deliver a first-class playing experience.

Detective 221B Bonus Features

Moving Wild

The magnifying glass Wild symbol can substitute for all other symbols on the paytable, aside from the bonus game and free spins symbols. This symbol can therefore help the most fortunate players to land additional winning combinations.

When the moving Wild symbol appears, it will move from right to left across the reels on every spin until it reaches the first reel.

If your session is completed before the moving wild reaches the first reel, it will remain visible during your next session until it completes its journey.

Bonus Game

When three or more gun bonus symbols appear on the reels, players will unlock the bonus game. This bonus game provides instant win prizes, which may boost your overall balance considerably if luck is on your side.

Free Spins

The violin symbol can unlock the game’s free spins round.

5 x violin = 20 free spins
4 x violin = 10 free spins
3 x violin = 5 free spins

If you are someone who enjoys slot games with a free spins round, then you’ll find plenty of options when searching the Slots Temple catalogue by feature. It’s also possible to search by theme, which means that it shouldn’t be long before you come across a new slot that piques your interest.
