Instructions
            
            
            To play this game click on blocks in groups of 2 or more of the same color.
            Larger groups are worth many more points than smaller ones (n2-n).
            
            Once there are no more moves the game is over.  A total score is computed by
            taking the game score minus a score penalty (10 x number left).
