Rank Chess is a variant of International Chess played on a board of twelve ranks by six files, with 30 pieces on a side, including two Kings per player. The goal is to capture or mate both opposing Kings. When a player still has two Kings on the board, either of their Kings may be captured like any other piece. When a player has only one King remaining on the board, normal rules for mate apply.
Pawns promote on the twelfth rank.
