Clobber Rules


Clobber is a two-player game where the last player to move wins—therefore, ties are impossible. You try to win by maximizing your opportunities to capture opposing pieces, while at the same time minimizing your opponent's opportunities to capture your pieces.


The standard Clobber board size is 10x10. Igfip™ supports a range of smaller and larger board sizes as well as rectangular boards and obstructed spaces.

Initial Clobber board position.


Each player starts with a number of pieces equal to half the spaces on the board. The pieces are arranged so as to fill the entire board, with each piece adjacent orthogonally to an opposing piece.


  1. Black moves first
  2. A piece may move to an orthogonally adjacent space that is occupied by an opposing piece. The opposing piece is replaced by the moving piece.
  3. The game ends when a player can no longer make a move on his turn. The last player to have moved wins.

Clobber Help


UnselectedSelected or MovedCaptured or ChangedMoved FromObstructions


Select a piece by clicking on it. Move a selected piece by clicking on the desired destination. If after selecting a piece, but before completing its turn, you decide to move a different piece, cancel the move by selecting another piece.

Alternatively, drag a piece from its existing position to its destination by placing the mouse cursor on top of the piece and holding the mouse button down while moving it. Cancel a move by dragging the piece back to its original location before releasing the mouse button.

Capturing Pieces

Capture an opponent's piece by clicking on it as the destination for the capturing piece's move.

Redraw Board

If you make an adjustment to your Web browser—such as changing your font size—while playing, the game pieces may no longer align correctly with the board. To restore proper alignment, select the Redraw command from the Clobber menu.
