Territopple

Territopple is a game in which at least two players compete for control of the game board. The board can be from a variety of sizes and geometries. Players take turns placing pieces onto the tiles that compose these boards. Players may only place pieces on tiles that they own or that are owned by no one. When a tile has more pieces than it has neighbors, it topples, giving one of its pieces to each of its neighbors and claiming them for the player who caused the topple, this is the only way to capture tiles belonging to other players. Players win when their team owns the entire board.
