あみだくじ/ amidakuji
あみだくじ（阿弥陀籤）とは、線のはしに当たりはずれなどを書いて隠し、各自が引き当てるくじのこと。現在は、平行線の間に横線を入れ、はしご状にすることが多い。数学的には横線が何本あっても、重複することはない。このことは数学的帰納法や背理法で証明できる。(ウィキペディア)
Ghost Leg (Chinese: 畫鬼腳), known in Japan as Amidakuji (阿弥陀籤^?, "Amida lottery", so named because the paper was folded into a fan shape resembling Amida's halo) or in Korea as Sadalitagi (사다리타기, literally "ladder climbing"), is a method of lottery designed to create random pairings between two sets of any number of things, as long as the number of elements in each set is the same. 
Part of the appeal for this game is that, unlike random chance games like rock, paper, scissors, amidakuji will always create a 1:1 correspondence, and can handle arbitrary numbers of pairings. It is guaranteed that two items at the top will never have the same corresponding item at the bottom, nor will any item on the bottom ever lack a corresponding item at the top. (wikipedia)
