Our intrepid adventurers have sailed on a journey, finding the hidden cave of a mythic monster. There are so many strange things there! The Captain allows the crew to search through the place and bring back to him what they have found, but by bluffing the Captain, they will try to keep the best part of the loot for themselves...
In Oh Captain!, an asymmetric game of changing roles, an adventurer must offer the loot cards they draw to the Captain, telling the Captain something about what the cards contain but not necessarily speaking truthfully. Indeed, some cursed objects can't be spoken of at all by the adventurers.
The Captain, who is safe from being attacked by objects, decides whether the crew member can keep the loot or not, and if the Captain turns down the offer, the crew member can decide to use an object against another adventurer. The latter player can overcome this by calling out a lie, winning or losing a coin based on who is right. The role of the Captain can be claimed by any adventurer who is richer than the Captain, and in the end the richest adventurer wins the game.
