Which character experiences the most significant change as a result of playing the Westing Game?

In my opinion, Angela experiences the most change. Over the course of the story, she learns how to stand up for herself, and unlike her initial attempt, which were self-destructive, she learns how to do so in a positive way.

In this short story by Ellen Raskin (the westing game). I think Turtle has had the most change in the westing game because, Turtle went inside of the westing house. Turtle was touched with a hand on her shoulder and she fell down the stairs. Turtle also got treated really badly through the whole book starting from pg. 1.
