Remove as many marbles as
possible from the board. The only legal moves are horizontal
or vertical jumps of one marble over another to an empty hole
on the other side. The marble that is jumped is removed from
the board. To move, just drag a marble in some legal direction.
The game continues until no
more jumps are possible. Score is based on how many marbles are
left at the end of the game. The fewer marbles, the better the
score.
