The object of the game is to create "super sandwich" comprised of ingredients that will provide the RDA (Recommended Dietary Allowance) of protein, calcium, iron, vitamin A, vitamin B-complex and vitamin C while not exceeding the RDA of calories. Players purchase foods and record the content of each nutrient found in these foods. The first player to accumulate the RDA of each nutrient while remaining within the allowable calorie intake makes a "super sandwich" and wins the game.
