Mr Jack Pocket

Discover the pocket version of Mr Jack, the favorite investigative game of fine strategists! As in the set version, a player plays the detective who tries to unmask Jack the Ripper while his opponent plays the role of the fugitive criminal. The difference lies in the game mechanics.
The infernal chase is now played on a tray of 3 squares by 3, each square representing both a London street and one of the nine suspects. Around the tray are the pawns Holmes, Watson and police dog.
In each round, the first player (the inspector or Jack, in turn) throws 4 action pawns that will move the investigator pawns, redirect tiles or draw a "suspicious" card. A suspect is visible if the investigator sees him in the line of streets in front of him. Suspects hidden by buildings are invisible. At the end of each round, the player who plays Jack must tell whether the guilty character is visible or not. If he is invisible, Jack wins an hourglass.
If he gathers 6 hourglasses, Jack wins the game (knowing that he can get hourglasses by remaining invisible and drawing "suspicious" cards). The inspector wins if there is only one suspect left in play at the end of a round.
