As you slowly drag the slider variable, the sprite says false, except for the one occasion (when it’s true). The wizGirl has found the mystery number! In this project, the variable 'which number?' and other variables were made local to wizGirl and wizBoy ('for this sprite only'). This makes it possible to run two or more separate puzzles simultaneously. See low to 20: https://scratch.mit.edu/projects/675421530
