Cut four large hearts from strong paper. Divide players into two equal lines, which face each other from opposite sides of the room. Give two of the hearts to the first player in one line, the other two to the player at the opposite end of the other line. At a signal these players place their hearts on the floor, one at a time, and hop on them to the other line, whirl and return to their own line, passing on the hearts to the player next in line who repeats. The winning line is the one finishing first.
