Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
The mini games are super fun and pretty addictive. The best part is that it's something my nephew can play as well. He's only three and loves feeding, playing games with and most of all he loves to teach the cat to talk. Overall tons of fun
