Cheir = Chess + Heir
A new competitive game that adds the secret of the "Regent" to chess.
■ What is a Regent?
Before each game, you secretly choose one Knight, Bishop, or Rook as your "Regent." Your opponent can't see which one.
■ Two Ways to Win
1. Checkmate (as usual)
2. Capture your opponent's Regent!
On top of normal chess, you must hunt and protect Regents. "Could that piece be their Regent?" — that mind game is what makes Cheir unique.
