Duplicitous is a light, simple, bluffing game of truth and deception for 2-players that plays in 5 minutes and uses only 9-cards. Each player is dealt 1 card and a common deck of 7 cards is setup. On a turn the start player draws a card and announces the card to be either a colour or number. Their opponent must determine if they are telling the truth or if they are lying. The winner collects the card face-up and the process repeats until all 7 cards are played - the player with the most cards at the end of the round is the winner. Duplicitous was designed for the The 2017 9-card Nanogame PnP Design Contest.
