Drop chance

Drop chance is the official term used exclusively in Asphalt Xtreme as an equivalent to "drop rate". Drop chances are listed in tables that can be reached by tapping on a box in the shop and then on the purple box info icon next to the box name.

Terminology

There are two important differences to the term "drop rate":

• In Asphalt Xtreme, "drop" means that a random number of a specific card is granted. In other words, it denotes the mere fact that a card occurs, but not how many of it. For example, if a box grants 4 drops, then players will get 4 times a random number of a card type. The real number of cards received from 4 drops can vary from 4 to 40.
• Contrary to other Asphalt games, the use of the word "chance" implies that "drop chance" not only denotes the average frequency of a card in the long run (= its drop rate, an expected value), but also explicitly means the probability of getting it. This is possible because Asphalt Xtreme Boxes do not have guarantees for certain cards. If a box contained a guaranteed card, the probability of getting it would always be 100 %, whereas the expected value would be different because the card does not make up 100 % of the box content.

According to the official tables, the drop chances of limited-time boxes (like special offers and event boxes) are all the same. It is striking that in this case, the term "approximate drop rates" is used instead of "drop chances". It would have to be analyzed statistically if this means that these boxes do have differences and the figures are just averages.

Furthermore it would have to be examined if "drop chance" refers to the above-mentioned "drops" or to the total number of received cards.

The official drop chances are listed below.
