Sorry for the 3 Basho absence of this game. Not that you really mind, But the rules are very simple: you guess the hoshitori a sekitori gets if he wins on the days you say he wins, you get a win, if he loses on the days you say he loses you get a win, if he wins when you say he loses, you lose, if he loses when you say he wins, you lose
highest score (closest preditction) wins.
