Overview

Key Largo is a simultaneous-action-selection game set in the Florida Keys in 1899. Players run treasure-hunting companies, hiring divers and buying equipment to search shipwrecks for gold and artifacts before Hurricane Katty arrives. Each day (round), all players secretly choose what to do – dive for treasure, sell at market, buy equipment, recruit divers, or take tourists dolphin-watching – then reveal simultaneously. The richest player when the hurricane hits wins.

Components

Setup

  1. Place the game board in the center of the table.
  2. Each player takes a boat, starting money, and starting divers.
  3. Shuffle the treasure deck and place it near the wreck locations.
  4. Set up the equipment shop, market, and tavern areas.
  5. Determine the hurricane track (10-day countdown).

Turn Structure

The game lasts 10 days. Each day has two action phases (morning and afternoon):

  1. Secret Selection: All players simultaneously choose a location/action for the phase by selecting a card face-down.
  2. Reveal: All players reveal their chosen locations simultaneously.
  3. Resolve: Actions are resolved at each location. When multiple players choose the same location, interactions and competition occur.

Each day consists of two such phases, giving players 20 total action selections over the game.
