In this game, players battle each other by showing one number card out of three open cards in their hands. The higher the number card is, the higher points you will get, but it becomes easier for your opponent to read your card, and harder for you to win. The lower the number card is, the easier you will win, but the lower points you will get. It is important to judge when to attack and when to defend. This is a psychological game, where the decisive factors are reading, bargaining, and intuition. —description from the designer
