It’s worth noting that although the product is credited to Disney Lucas Films Ltd. (which, written that way, isn’t a real company), it was listed by P & E Enterprises and Amazon product descriptions are written by the seller. While it’s possible that the seller had some kind of insight into Finn’s backstory, and it wouldn’t be the first time that merchandise
has revealed details about
Star Wars characters, it’s equally possible that the seller got the information wrong or simply assumed that Finn was Lando Calrissian’s son because they share the same skin color. Jason Ward of
Making Star Wars says that he has seen the puzzle in real life, and it gives no indication that Finn is Lando’s son.
