In Fianco, which is Italian for "side" or "flank", you want to be the first player to move one of your pieces to the opponent's back line.
On a turn, you move or jump with one of your pieces either forward (whether orthogonally or diagonally) or sideways; backwards movement is prohibited. You must take an opponent's piece, if possible, but only one at a turn. Control over the sidelines is important since pieces there cannot be jumped as easily.
