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.
Amazing! Our son loves this and the pieces are solid wood. Quality is also good. Someone mentioned previously that the pictures would come off from the pieces but I think they have changed that since I can't imagine how they could even come off since they look almost like the picture would be printed on the wood. Would recommend and would buy again (when our son has lost enough pieces and we can't find them any more).
