Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
The kids love this game, as it's just like running their own pizza shop! The interactive nature of making the pizzas is so much fun. I love that the game requires the children to consider many real-world challenges to be successful (service, customer reviews, wages, rent etc)
