Overview

Borneo is a card game of spice trading in the 17th-century East Indies. Players are merchants belonging to multiple mercantile companies, competing to achieve the best positions within company hierarchies at the right time, when the profit from expeditions is divided. Cards serve triple duty: gaining control of companies at harbors, advancing in company rank, and as trade goods to fulfill shipment orders.

Components

Setup

  1. Place the board in the middle of the table.
  2. Sort the cards by the symbol on the back: Shipment cards and Harbor cards.
  3. Give each player three merchants with the same portrait and the matching summary card (four merchants in the 3-player variant).
  4. Shuffle the shipment card deck and deal three cards to each player.
  5. Prepare harbor cards based on player count — remove specific cards to maintain balance.
  6. Players then place merchants into company columns across three alternating rounds.
  7. Missions are sorted by value and displayed face up.
