International Award-winning Save The Turtle explains to children aged 4-9 how harmful plastic is for sea turtles, (as they mistake it for food and die) through its multi-maze puzzles game (24 different quizzes). In each quiz, they have to save the turtle from the harmful plastic (visualized as a bottle and plastic bag) and take it to a safe place. Doing more and more quizzes strengthens the idea in their minds that plastic is harmful.
