Overview

Caribbean is a pirate-themed bidding and movement game set in the 18th century Caribbean. Six neutral pirate ships patrol the seas, and players bid barrels of rum to bribe these pirates into acting on their behalf. Ships capture treasure chests from port cities or steal them from other ships, then deliver them to players’ safe havens for doubloons. No ship belongs to any player — control is won each round through bidding. The player with the most doubloons at game end wins.

Components

Setup

  1. Each player takes a card holder and a set of 7 bribing cards in their color. Place the card holder so ship names are visible.
  2. Shuffle the 16 treasure chests face down. Place 6 randomly face up on the ports indicated on them.
  3. Place the remaining 10 treasure chests face down in piles of 2 on the five special spaces in the upper right corner of the board (treasure chest supply).
  4. Place coins next to the board as a bank.
  5. Place the 6 pirate ships randomly on the starting spaces marked with ship symbols. These symbols have no further importance during play.
  6. Each player has 3 safe havens marked in their color on the board.

Turn Structure

Each round has two phases:

Phase 1 — Bidding:

Phase 2 — Ship Movement (alphabetical order): Ships are resolved one at a time in order: Arriba → Bravo → Caribic → Diabolo → Evita → Fuego.

For each ship:

  1. All players reveal their bid for that ship.
  2. The highest bidder moves the ship up to a number of sea spaces equal to the barrels shown on their bid card.
  3. Each thief card played by opponents subtracts 1 space from movement.
  4. The winning bidder may take actions (capture, steal, swap, deliver) before, during, or after moving the ship.

Actions
