Overview

Cities: Skylines – The Board Game is a cooperative city-building game where players work together to build a thriving city. Players complete milestones that represent periods of construction, managing resources like money, happiness, utilities, and employment. The quality of cooperative efforts is reflected in the happiness of residents. The game is played through scenarios of increasing complexity, with Scenario 4 containing all rules and elements.

Components

Setup

  1. Assemble game board pieces in the center of the table (varies by scenario).
  2. Place the administration board face up next to game boards; place 8 markers on “0” spaces.
  3. Deposit starting capital of 12 money tokens in the city treasury.
  4. Sort all zone and building tiles by color and type.
  5. Shuffle Stage I construction cards and deal based on player count: 4 players = 3 cards each, 3 players = 4 each, 2 players = 5 each, 1 player = 7 cards. Remaining cards form draw piles by stage.
  6. Place the happiness display (Skyline) next to the administration board with indicators on “0.”
  7. Youngest player gets the starting player token.
