Random collection

A random container is a generic term to describe containers that grant random items in the Asphalt games. First implemented as Pro Kit Boxes in the Winter Update of Asphalt 8, they mark the introduction of gambling elements to the games.

Their names vary from Card Pack in Asphalt 9, Box in Asphalt Xtreme to various subtype names like Package, Bundle or Special Offer&mdash;but they all have in common that they are random processes where a number of items can be drawn from a container.

In terms of probability theory, random containers are variations of the classic urn model: An urn contains x white and y black balls, well-mixed together. One ball is drawn randomly from the urn and its color observed; it is then placed back in the urn (or not), and the selection process is repeated.
