Overview

Jerusalem is an auction and area control Eurogame set in 12th-century Jerusalem during the Crusader period. Players compete to control the six key sectors of the city: the King, the Church, the Market, the Military, the Nobility, and the Tower of David. Control is gained by winning the favor of important city roles (such as the Constable) and placing Men and Barons into sectors. Revenue from controlled sectors provides resources to build towers, and the player who builds the highest tower wins.

Components

Setup

  1. Place the game board in the center showing the six sectors of Jerusalem.
  2. Each player takes their Men, Barons, Gold, and Tower pieces in their color.
  3. Set up initial role cards and sector configurations as specified.
  4. Determine first player.

Turn Structure

Each round consists of:

  1. Auction Phase: Players bid to gain the favor of important city roles. Winning a role grants special powers and placement advantages.
  2. Placement Phase: Players place Men and Barons into the six sectors of the city.
  3. Revenue Phase: Each sector provides revenue to the player who controls it (has the most forces there). Revenue comes in the form of Men, Gold, and Tower-Points.
  4. Building Phase: Players spend Tower-Points to add floors to their personal towers.
