Strange Rule

In your turn, you make up a rule without disclosing it. You divide your cards into two groups according to your rule. Every other tries to guess your rule in mind from your grouping, and plays a card into either group. Players score if their played card satisfies the actual rule. The main player scores only if the rule is not too simple or difficult. —description from the back of the box (translated) 理性和感性並用的聚會遊戲《奇異法則》第一彈，將以《夢想方塊動物園》為主題，大量可爱的動物插畫一併奉上！ 發動你的想像力、觀察力和創意，用一條奇異的規則將手中的卡牌分為兩類！這條規則既要天馬行空、出人意料；又不能於亂無章法、無跡可依。用你的法則迷惑的對手，並參透別人的規則吧！ —description from the back of the box
