# Which blind-box probability model fits? https://thedollscout.com/collecting/blind-box-rules Content updated: 2026-10-02 Use independent-draw math only when each box has the same chance and previous outcomes give no information about the next one. A printed rate needs a target First ask what the number describes: one named regular style, any secret, or one particular secret. These are different events. A combined secret rate cannot be reused as the chance of one secret when several exist. Record the exact series and packaging source beside the rate. A full case is a different purchase A stated non-repeating assortment links the boxes together. The HIRONO Mime listing describes such a whole set; SMISKI warns a secret may be absent from an assort box. Neither statement supports treating all case contents as independent. Follow the exact package terms. Equal styles are an assumption Our regular-style model allocates the non-secret probability equally. Tier labels such as those on MOLLY Series4 do not justify that assumption. Use a verified single-style percentage when regular styles differ, and leave an unknown value blank. What a result means With a hypothetical 5% chance per independent box, six boxes give 26.49% for at least one hit. The opposite outcome still has a 73.51% chance. Earlier misses do not change the next independent box. A 90% threshold remains uncertain and is not a spending recommendation.
