YWF (Yoi-ko, Warui-ko, Futsu-no-ko) is a strategy board game for two players. One plays as "Yoi-ko", which means "Good boy", and another plays as "Warui-ko", which means "Bad boy", and they try to become the majority on the board. In addition to "Yoi-ko" and "Warui-ko", however, there are unstable "Futsu-no-ko", which means "Common boy", too...

YWF is a game similar to Reversi (or Othello), but its piece status has "neutral" in addition to "black" and "white". The difference is very small, but it makes the game more complex, puzzling, and interesting.
