Cerebria, the Card Game focuses on occasions when the landscape of your mind interacts with the world and other people. In this turn based card game the players build their Mindsets, filling it up with Bliss or Gloom Emotions. The outside world is represented by the Impulse, a dynamically changing pool of available Emotion cards. Whenever the Impulse is emptied of Emotions, each player’s Mindset is scored, granting Bliss or Gloom Identity Fragments. The goal of the game is to collect enough Fragments to fully develop the Identity.

The deck consists of 96 Emotion cards. Each Emotion can be played either into the Mindset or for its effect. Emotion effects can interact with other Mindsets, other players’ hands, the Impulse, or even other Emotion effects by cancelling them.

The game ends if one of the players manages to build a fully single-minded (Collecting 8 or more of one type of Fragment) or a balanced personality (Collecting 5 or more of both Fragment types).
