Overview

Goa is a strategy game where players take on the role of Portuguese spice merchants in 16th-century India. Each player expands their business by building ships, harvesting spices, collecting taxes, mounting expeditions, and founding colonies. The game is divided into two phases (A and B), each containing 4 rounds. Each round features an auction for tiles followed by individual player actions. The player with the most victory points at the end wins.

Components

Setup

  1. Place the board centrally. Shuffle 29 A-tiles, remove 4 (max 2 Plantations), and arrange remaining 25 face-up in a 5x5 grid.
  2. Place spice sacks, ducats, ships, colonists, extra action cards, and colony tiles on their board spaces.
  3. Shuffle expedition cards face-down on the board.
  4. Each player takes personal board, development board, and auction tokens in their color.
  5. Players use tokens equal to player count + 1 (5 with 4 players, 4 with 3, 3 with 2).
  6. Each player places 1 progress marker in the first box of each development column (5 total).
  7. Each player starts with 4 ships and 2 colonists.
  8. Determine first player by revealing expedition cards (first elephant revealed). First player gets flag and 5 ducats; others get 10 ducats.

Turn Structure

Each round follows two stages:

Stage 1: Auction

  1. Flag placement: First player places flag on the board and their #1 auction token on it.
  2. Token chain: Players take turns placing tokens on tiles adjacent (orthogonally or diagonally) to the previously placed token, forming a chain.
  3. Bidding: Starting from the highest-numbered token, the tile owner (token placer) auctions their tile. Other players bid with ducats (ascending). If no one bids, the owner gets the tile for free.
  4. Flag tile: The first player auctions their flag tile. The winner becomes first player next round and gets the flag.

Stage 2: Actions

Starting with the first player and going clockwise, each player takes exactly 3 actions per round.

Actions

Players choose 3 actions from the following (each action taken once, plus possible extra action cards):

1. Harvest Spices

Collect spices based on your Harvest development level. Higher levels = more/better spices.

2. Build Ships

Gain ship cards based on your Ship-building development level.

3. Collect Taxes

Gain ducats based on your Tax development level.

4. Mount Expedition

Draw expedition cards based on your Expedition development level. Spend expedition cards to found colonies.

5. Found Colony

Pay required ships and colonists to claim a colony tile, which provides VP and ongoing benefits.

6. Develop

Advance one space on any track of your development board by paying the required cost (ducats, spices, ships, or colonists depending on the track and level).

Extra Actions

Extra action cards (gained from tiles) grant additional actions beyond the standard 3.

Development Board Tracks

Five tracks with 5 levels each:

Each advancement costs resources that increase with level.
