Cerebria - The Card Game is a turn-based card game, where players build their Mindsets, filling it up with Bliss and Gloom Emotions. Players fill their hand with Emotion cards from the Impulse, a dynamically changing pool of available Emotion cards. Whenever the Impulse is emptied of Emotions, a Revelation takes place; this is when 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.
Players can gain Fragments by invoking Emotions into their Mindset. However, these Fragments can be spent on the effect of the Emotions' Abilities, so it is up to the players to decide whether they hold on to their victory points or spend some of them to be more efficient. Emotion Ability effects can interact with other Mindsets, other players' hands and the Impulse; but they can be canceled by discarding Emotions of the matching type.
The game ends if one of the players manages to build a fully single-minded (collecting twelve or more of the same type of Fragment) or a balanced Identity (collecting seven or more of both Fragment types each).
