The homepage of a miniclip game called bad apple. It's got a guide, saying: "Click on an apple to bite into it. If you eat a good apple it will reveal the number of adjacent bad apples (including diagonally. For instance, if a good apple reveals the number 1, there is 1 bad apple adjacent to it. Try to eat only good apples. If you eat a bad apple, the game is over. Good Luck!"
