Real Queen

Alternately, the two opponents place a marble on a space of a 7x7 grid. As soon as a player has at least four of his own marbles in a consecutive row, he captures one (or more, in the case of longer rows) of his opponent's marble(s), but must take back at least two of his own with which he formed the winning row, thus suffering a positional disadvantage. An oversized marble called Queen may either be used to complete a Real Queen or because it is the last one remaining. If the Marble's Queen is part of a winning position, it allows players to earn an additional marble. If the opponent completes a row of four (Real) with at least one marble in the adjacent to the Queen, he has won immediately. If you have no more marbles in your supply, you can move the marbles on game board anywhere you like, but the Marble's Queen is only allowed to move to an adjacent square.
