What is the game calld that Leo and Stargirl play at the mall?

The
answer to this question can be found in chapter 21. This chapter explains the "game"
thatplays and teaches to Leo. They play three rounds of it during this chapter; however, readers
and Leo are not told that the game has an official name. If I had to name it or guess what
Stargirl might call the game, I would call it the "Empathy Card Game." The chapter
begins with Stargirl telling Leo where she gets her information about people and what they might
need to make them feel better. She reads the "filler" sections of the newspaper. She
eavesdrops on conversations at places like the hair salon, and she reads bulletins boards around
town. Stargirl then asks Leo if he wants to play "a card game." Leo immediately knows
that she isn't talking about a game with an actual deck of cards. He agrees to play, and
Stargirl explains the game to him.

She poked me. Hey,
want to play a card game?

I had a feeling she wasnt talking about
poker.

Sure, I said.

She said she invented it. All you
need is your eyes and one other
person. I pick somebody on the street, the mall, a
store, wherever, and
I follow them. Say its a her. I follow her for fifteen minutes,
not a
minute more. I time myself. The game is, after fifteen minutes
of
watching her, I have to guess what kind of card she needs.

Leo likes the idea of the game, and he agrees to play it, but he is
confused about how to get the cards to the person if they don't know the address. Stargirl
explains that the person is never sent an actual card for that reason, and that is why it is
only a game.

But how can you get it to her? I said.
You dont know where she
lives.

True. Thats as far as it goes.
Thats why its just a game. Its just for
fun. She snuggled into me. She whispered in my
ear, Lets play.
