Prepare several heart-shaped bingo cards from posterboard or construction paper. Write "I Love You" on them in large letters. Put the candy hearts in a bowl. Players take turns choosing a candy heart from the bowl and reading the words on it. If there is a letter on the candy heart that matches a letter on the card which has not been used already or covered up, they can take a piece and put it over that letter. Then it's the next players turn and so on. The first one to cover all the letters in "I LOVE YOU" wins.
