Deep Sea Adventure

2-6 players 30-30 min 6.9 Board Game Geek Rating

Rival treasure hunters share a rented submarine and limited air supply while exploring underwater ruins. Players move by rolling dice, collecting treasure chips from the seabed. Each round, you must return to the submarine before the shared air runs out, or lose all treasures. After three rounds, whoever collected the most treasure points wins.

Get Ready

Setup the game with these step-by-step instructions before diving into your turn.

Position the submarine

Place the Submarine board in a location clearly visible to all players

Set the air marker

Place the air marker above "25" on the submarine board

Prepare treasure chips

Flip the underwater treasure chips face-down to hide their values, separate them by Level, and shuffle each level well

Arrange the treasure line

Align the Treasure Chips in order by Level from low to high, connecting them to the submarine board in a single line (any arrangement forming one line is acceptable)

Select diver pieces

Each player takes one sea diver piece according to their preference and places it flat on the submarine board with the pointed belly facing downward

Determine first player

The player who was in the ocean or went swimming most recently takes the first turn

On Your Turn

What you can do during your turn.

Step 2: Declare direction

Decide whether to turn back or continue diving deeper

Step 3: Swim (roll dice and move)

Roll both dice and move your diver piece in the direction it faces along the line of underwater chips

Step 4: Treasure hunting (pick up or drop treasure)

Winning

How to claim victory.

Game structure

The game takes place over 3 rounds (3 deep dives), with each dive starting with a full air tank and all divers in the submarine

Scoring treasures

Players who returned to the submarine reveal their Treasure Markers and discover their values; keep these markers to score at the end of the game

Failed return penalty

Players who did not return to the submarine before the dive ended leave their treasure at the sea bottom; in turn order starting from the diver closest to the submarine, players place their Treasure Markers (in any order they choose) next to the last marker in the underwater treasure line

Round cleanup

Remove all blank Underwater Treasure Markers from the line and connect the remaining markers to close any gaps

Next round first player

The last player to return to the submarine takes the first turn of the next dive

Final scoring

At the end of the third dive, after cleanup, players sum their points (values of all Treasure Markers brought back to the submarine)

Determine winner

The player with the most points wins

Tiebreaker

If tied, the player with the most high-level treasure markers wins; if still tied, the game ends in a draw
