The Game of Flying Obelisks

The Game of Flying Obelisks is played on a 9x9 board with two raised 3x3 "hills." Each player has a set of 17 pieces of 8 different types, and there are also 5 neutral obelisks. On a turn a player moves a piece according to its specific movement rules. Moving to a space occupied by an enemy piece captures it. Moving to a space occupied by a friendly piece creates a stack; a stack can have up to three pieces (with some restrictions) and can move as any of the pieces in it. By moving pieces to the opposite rank a player may recover lost pieces or acquire obelisks. Obelisks allow stacks they are with to teleport from one hill to the other. (Movement onto and on hills is fairly restricted.) The object of the game is to capture the opposing globe (which moves like a Chess king) or to occupy both hilltops (the center squares of the hills) and have no enemy pieces on the hills. Note: this was claimed to be a reconstruction of an ancient board game, but that was an April Fool's joke.
