Gungi is a two-player strategy board game created by Yoshihiro Togashi and is featured in the in the popular manga
Hunter × Hunter.
It is played on a non-checkered gameboard with 81 squares arranged in a 9x9 grid. At the beginning of the game, players can choose how their pieces will be arranged on their side of the board.
Additionally, unlike its spiritual brethren, chess, shogi, and go, in Gungi pieces can be stacked on top of each other, adding a third dimension to the game leading to billions and billions of possibilities. As in chess and shogi, the goal is to trap the king.
There are 13 unique pieces with different ranges of mobility at different tiers.
Note: Blue means the piece can move into that square. Green symbolizes the ability of that piece to move in a continuous line along the path of that square.
