A Booster Pack (Japanese: ブースターパック Būsutā Pakku) is a pack of Yu-Gi-Oh! cards from one of the Booster Sets, the main sets from where new cards are released. Booster Packs can be bought at most game stores and at some general/department stores.
As of Breakers of Shadow, the ninth card is guaranteed to be at least a Super Rare, with a 1:6 chance of it being an Ultra Rare and a 1:12 chance of it being a Secret Rare. This also applies to side series sets such as High-Speed Riders and Wing Raiders. Previously, the chances of a single pack containing a Super Rare was 1:5, with Ultra Rare and Secret Rare chances being 1:12 and 1:23; in some older historical sets, the latter two chances were 1:24 and 1:31 instead.
