Overview

Archipelago is a semi-cooperative game of exploration and colonization set during the Age of Discovery. Players explore a modular archipelago, gather resources, build settlements, and manage native populations. Each player has a secret objective that determines victory, but all players share the risk of colony-wide rebellion. If the rebellion level gets too high, the game ends and a “sympathizer” player (if present) wins, while everyone else loses. The game blends Euro-style resource management with negotiation, hidden objectives, and variable game length.

Components

Setup

  1. Place the starting hex tiles as indicated. Set up the market board.
  2. Each player takes a player board, starting resources, and ships.
  3. Shuffle and deal secret objective cards (one per player).
  4. Prepare the evolution, trend, and character card decks.
  5. Set the rebellion track to its starting position.
  6. Determine first player.

Turn Structure

Each round:

  1. Balance of Power: Determine turn order.
  2. Action Phase: Players take turns performing actions (exploring, building, harvesting, trading, etc.).
  3. Crisis Phase: Reveal and resolve a crisis card. All players must collectively meet the crisis requirements or the rebellion track increases.
  4. Market Phase: Adjust market prices based on supply and demand.
  5. Check End Conditions: If an end-game trigger occurs, proceed to scoring.

Actions

On your turn, you can perform several actions:

Scoring / Victory Conditions

Game End Triggers (variable):

Scoring: Each player’s secret objective determines which accomplishments score them points. Common scoring criteria include: most resources, most territories, most buildings, most money, etc.

Rebellion Loss: If the rebellion track reaches its maximum at any point, the game ends immediately. If a “sympathizer” player exists, they win. All other players lose.
