Worst Enemy is a (mostly) cooperative trick-taking card game with rotating hidden roles and one-vs-all mechanisms. It's designed for 2 to 4 players ages 12 and up, and lasts between 30 - 40 minutes.
The premise is that you all play as parts of a single mind, however, each round one of you will take the part of the Core Personality who shoulders the sole responsibility of scoring for the group. The other players take on the roles of negative personality traits each playing with a unique rule that confounds how the tricks play.
The game is a race against your bad tendencies as each round you lose advances a Worst Enemy token closer to the end of the score track. Can you work together to score enough tricks to reach the end, or will you prove that old adage once again, "Sometimes you are your own worst enemy"?
