A group of poor explorers looking to get rich, quickly heads out to recover treasures from some undersea ruins. They're all rivals, but budgets force them into a single rented submarine. They all have to share a single tank of air, as well. If they don't make it back to the sub before they run out of air, they'll drop all their treasures. Now it's time to see who can bring home the most riches.
The game is played over 3 rounds, and the player to earn the most points over the 3 rounds is the winner. In order to earn points, you must bring the majority ruins chips back to the submarine. You can only return to the submarine once per round, and you can't advance more after returning. You also can't return to the submarine without any ruins chips.
On their turns, players perform steps 1-4 listed below. Players take turns, clockwise around the board, and the round ends when all players have returned to the submarine, or if the air runs out at the start of someone's turn.
1) State if you will turn back or not.
2) Reduce air.
3) Roll dice and move your game piece.
