Description from the designer:
Debate (formerly known as Discussion) is a 18 cards microgame in which you try to create a coherent speech using your resources at hand and your memory, and forcing your opponent to flip its ideas.
Debate is being played with an 18 cards deck with different symbols on them. It is very important to differentiate between the front and back of each card. The backs contain only two symbols, 9 corresponding to one player (red) and 9 for the other (green). The hand of each player is always held with the backs facing the opposite player. The cards are played next to others on the table showing their back sides and triggering some effects. You win by forming a group of connected cards of your color greater than your opponent’s.
