Section 2: The Deck
Why People Get This Wrong
People often assume that the standard pack in cribbage means it can be any 52-card deck they like, forgetting about the specific composition of the cards (like jokers or non-standard suits) which isn't mentioned in the rule. The confusion arises because the official verdict only specifies the rules for a standard pack without elaborating on what exactly constitutes a "standard pack" in cribbage.
Official Verdict
A standard pack of 52 playing cards is used; jokers are discarded (Rule 1.3.a).; The four suits are considered equal (Rule 1.3.b).; Card rank and value run K–Q–J–10 (each worth 10), then 9 through Ace worth their pip value down to 1 for the Ace (Rule 1.3.c).
