Kavi Builds a Forest Quiz

Kavi wanted to make a quiz about the forest for friends to play. First Kavi set a score to 0. Then Kavi asked a question: "How many legs does a spider have?" The player tapped an answer. Now Kavi used a choice — a bit of selection: IF the answer is correct, add 1 to the score · ELSE keep the score the same. Kavi asked a few more questions, each one checked the same way. At the end Kavi showed the final score. "A quiz is just a loop of questions," Kavi hooted, "where a choice decides whether the score goes up!"
