Overview

Orient Express is a deduction mystery game set aboard the famous train traveling from Paris to Istanbul. Players are detectives investigating a crime by moving through the train carriages, interrogating passengers and staff, and searching compartments for clues. The game includes 10 different mystery plots that are played in sequence. The detective who correctly identifies the culprit(s) while using the fewest clues wins. Published by Jumbo.

Components

Setup

  1. Place the board in the center of the table.
  2. Each player selects a playing piece and places it on the connection between the two carriages.
  3. Each player takes 2 chips in their color.
  4. Place the train marker on the Paris section.
  5. Distribute note-paper sheets (1 per player).
  6. Select a mystery plot (play in order, starting with #1). Tear the cards along perforation without reading them.
  7. Place the 30 ordinary clue cards face down on their corresponding board sections (matching names).
  8. Set the 2 super clues and reconstruction aside face down.

Turn Structure

Players take turns in clockwise order:

  1. Roll the special die.
  2. Move your detective through train sections (up to the number rolled). Sections are separated by dotted lines.
  3. Optionally read one clue card from the section where your detective stops (interrogate a person or search a room).

Actions

Scoring / Victory Conditions

When a player believes they know the culprit(s):

  1. Write the solution on their note-paper (do not reveal).
  2. Count the number of face-up clue cards at that moment.
  3. Add 6 points if Super Clue I was used; add 10 more if Super Clue II was also used.
  4. Record the total on the note-paper.

Other players continue until they also find a solution or the train reaches Istanbul.

When the train arrives in Istanbul, read the reconstruction to reveal the answer. Among players with correct solutions, the one who used the fewest total clue points wins.
