In this turn-based detection game, two teams face off against each other: Jack the Ripper and the detectives. Jack has to get away with murder without being found out by the detectives, who in turn need to find out who he is. Unlike other detection games, you can't talk with the other players in Jack & Detectives, and you must figure out the truth based only on their actions. Players cannot get eliminated, so everyone gets to enjoy the game to its end. Furthermore, since a game only last ten minutes, you don't need to commit a lot of time just to play.
A serial killer lurking in the shadows. In order to win, he must make sure he isn't chosen during the voting phase.
Private detectives hired by the London police. In order to win, they must correctly vote Jack out during the voting phase.
A maniac whose allegiance lies with Jack the Ripper. He wins if Jack wins, even if he gets voted out himself.
At the start of each game, players are assigned a role at random. Then, everyone places their token on a London tile of their choosing.
Once they have done so, night will fall, and Jack the Ripper will commit his first murder. (In certain cases, there will be no murder during the first night)
The detectives located near the crime scene will become suspects. Who's on justice's side? Who's the murderer among us? After the second murder, the voting phase starts. Everyone has to vote for the person that they think is secretly Jack the Ripper. This is where the real battle of wits between the detectives and Jack starts.
You can play online against console and mobile users.
Win matches against worldwide challengers to earn rank points. Once you have enough rank points, your rank will go up.
Host a room to play against your friends! In room matches you can also customize the rules to your liking.
Lots of option to personalize your avatar, token, and animations.
Look back to the matches you've played in the past for useful insight.
Play against the computer to improve your skills.
