The object of this game is to connect all your pieces in a single group. Each turn, a player moves a piece horizontally, vertically, or diagonally. The number of spaces a piece can move is equal to the total number of pieces in that horizontal, vertical, or diagonal line. For example, in the first move of a game player 1 can move any piece in the top row down 2 cells, because there are 2 pieces in that vertical line. During a move, a piece can jump over friendly pieces but not enemy ones. A move can end on an enemy piece in which case the enemy piece is captured and removed from the game. Friendly pieces cannot be captured.
A player wins when all of her pieces in one connected group. Horizontal, vertical, and diagonal connections are valid. A single piece is considered to be a group, so if all but one of a player's pieces are captured, that player wins immediately.

Player 2 (blue) can move the highlighted piece diagonally left and down 3 squares, because there are 3 pieces in that diagonal line. It can jump over the friendly piece to land on the highlighted empty cell. (It could not make that move if the intervening piece was an enemy).

Player 1 (red) wins by moving the highlighted piece 2 cells down and connecting all the red pieces.
