Shoujiki Shogi is a segment of AKB48's variety show, AKBingo! In this segment, 2 members faceoff against each other, asking personal questions to each other while hooked up to a lie detector. The answerer is required to say "no" each time in responce to each question. Each time the lie detector spikes is a point for the one who asked the question. 3 points to win the match.
