@novocode @sanmei: I am agree with you that the game shouldn't be end prematurely before all of the cells are converted to player's or opponent's cell. But the game will be a one man play if we let the player to keep moving (it's not a turn based game anymore). On my perspective, there should be a way to determinate lockings before it's happen (ie. when there's no way to convert a cell on the opponent's area) and play an animation to fast forward the play till it's end (as if the game is know that one side is win).
