Overview

Arkham Express is a cooperative print-and-play dice game for 1-4 players set in the Lovecraftian Arkham Horror universe. Players work together to gather clues, kill monsters, close gates, and ultimately defeat Cthulhu. Each player controls a character with a unique special ability. The game distills the Arkham Horror experience into a quick, dice-driven format.

Components

Setup

  1. Place the game board in the center.
  2. Each player selects a character and takes the matching pawn and character sheet.
  3. Place starting gates and monsters on the board as indicated.
  4. Place player pawns at their starting locations.

Turn Structure

On your turn:

  1. Roll all 5 dice.
  2. Lock Monster dice: Any dice showing the Monster symbol are locked and cannot be re-rolled.
  3. Re-roll: You may re-roll any unlocked dice up to 3 additional times (4 total rolls).
  4. Resolve dice: Use the symbols rolled to perform actions.
  5. Check for gate opening: If 3 or more Monster symbols are showing after any roll, a new gate opens and a monster appears.

Actions

Movement (Movement symbols): Move your pawn to an adjacent location on the board. Each movement symbol moves you one space.
