I prefer to play this with the variant or advanced scoring method that considers the weight/sizes of all the various shaped pieces - basically each piece has it's own point value equal to it's weight. Here's the formula: 1 Gram = 1 point.
Rules of play are the same but scoring is the player with the most grams or points wins. (See images #78940 and #78941. The pieces are easily discernible so just print out a copy of the two photos that show all the black & red shaped pieces and their assigned points or weight of each piece.) Most points by grams is the winner.
