Gameplay

In A Night of Mystery, your goal is to collect clues and help the detective find the culprit behind a murder among four temptresses hiding dangerous secrets. With a classic ‘who dun it’ plot and a free spins round to make Sherlock Holmes scratch his head, this slot will take you to the crime scene of a complicated case where many secrets have to be unraveled. On the reels, you will see the investigator, as well as the beautiful ladies who all seem dangerous enough to have committed the sinister deed. They are the highest paying symbols, while the standard Ace to 10 card symbols are the lower values. In the Clue Collection bonus game, you will also come across eight additional symbols, such as a lipstick, knife, whip, dynamite and more, all providing hints that could tie the ends of this crime.
