Anti-Grid is an abstract board game for two players in which each player has their own grid to move upon. These two grids are intertwined on the board, but do not share any paths. Moving, blocking, and capturing are all done without the players interacting directly. Captures are achieved by a flanking maneuver, and the path of an enemy piece can be blocked in a similar way. Intriguing patterns emerge in the pursuit of the objective: to eliminate or trap the opposing force so they no longer can achieve a win.
