Solo felt like it was just a film about the cold war (although it was good) because of all the betrayals and double crossings and who’s with who. I also still don’t really understand what the significance of the chained dice because at first ,because it was hanging in the millennium falcon, i thought it meant that maybe he won the falcon with them but he had the dice before that and sabacc doesn’t involve dice (it already stated he one it through sabacc before the film). We don’t have much info about his family or the space gypsies that took him in so it could have been a gift or something.
Just a good luck charm I believe. Where it came from doesn’t seem to matter as much as what it means to him.
