Corps of Discovery Duo 2026

A stand-alone game for 2, based off the hit deduction game, Corps of Discovery, this game has 2 players working together to create a map by following specific logic rules.

Players know some communal logic rules, but also each have some hidden behind their screen. Can you communicate only through your card placement what your rules are to your partner, while trying to figure out their rules?

On your turn you play one of your cards onto an ever-expanding map. If you don't like where your partner played a card because it violates one of your logic rules, then you can pay the current penalty (which is discarding cards from your deck) to remove any card in play.

If either player has no more cards to play, then the game is over and you both lose.

If at least 1 of each of the 10 terrains is in play, then either player could play the fort card - in a location that adheres to its own logic rule. Then review to see if all the cards on the map follow all the logic rules in the game - and if they do - you win! It includes an Upgrade system as you progress from game to game, while also adding hazards that add new challenges each time you play.
