As in many games, the ultimate goal of this one is to get as high of a score as possible. You will bring your score up by pairing foods. You will also notice that there is a yellow time meter, which is on the right side of the square with all the foods in it. The yellow in the time meter is slowly but constantly getting lower. Every time you get a pair of foods, you are rewarded both in your score, and a little bit of yellow is added back to your time meter. Concerning foods around the perimeter of the square, if there is any that match, you can pair them up even if they are not directly next to each other, as long as they are in the same row. In any other rows of the square, the foods must be directly next to each other either longitudinally or latitudinally. That is to say, they must be next to each other in either a vertical or horizontal straight line. If you try to match up foods diagonally, it will not work. It is up to you to pair up foods. When you've run out of foods to pair up, press the shuffle button above the foods square to get a new arrangement of foods, which will enable you to find new pairs.
