How these odds are calculated

The calculator uses the stated secret ratio for each series. Individual boxes and virtual simulator pulls are treated as independent draws. Sealed cases are treated as independent cases with no more than one secret in each case, where a secret replaces a regular design. Simulator results are random examples, not predictions. All results are mathematical estimates, not guarantees, and real stock distribution may vary. Cutiemalta is an independent retailer; product names and trademarks belong to their respective owners.
