Deep Sea Adventure is a board game released in 2014 for 2–6 players, 30 minutes per game, and ages 8 and up. It was designed by Jun Sasaki and Goro Sasaki and its main mechanics are Push Your Luck, Roll / Spin and Move, and Track Movement.
A group of poor explorers hoping to get rich quickly heads out to recover treasures from some undersea ruins. They're all rivals, but their budgets force them all to share a single rented submarine. In the rented submarine, they all have to share a single tank of air, as well. If they don't get back to the sub before they run out of air, they'll drop all their treasure. Now it's time to see who can bring home the greatest riches. Game Objective The game takes place over 3 rounds, and the player to gain the most points over the 3 rounds is the winner. In order to gain points, you must bring the most ruins chips back to the submarine. You can only return to the submarine once per round, and you cannot progress more after returning. You cannot return to the submarine without bringing any ruins chips. Turn Progression On their turns, players conduct steps 1-4 listed below. Players take turns, going clockwise around the board, and the round ends when all players have returned to the submarine, or if the air runs out at the beginning of someone's turn. 1) Declare if you will turn back or not. 2) Reduce air. 3) Roll the dice and advance your game piece. 4) Search. (When you have stopped moving, select one of A-C below) A) Do nothing. B) Pick up ruins chip. C) Place a ruins chip.
Deep Sea Adventure supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Deep Sea Adventure is 30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Deep Sea Adventure for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Deep Sea Adventure has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
