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, usually every three to four months. 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.
