What is a pure sequence?
A pure sequence is a group of consecutive cards from the same suit without using a joker to replace a missing card.
For example, 4, 5, and 6 of clubs form a pure sequence because the cards are consecutive and all belong to clubs.
Why it matters
A valid 13-card rummy declaration generally needs at least one pure sequence.
Without it, even a hand that looks organized can become an invalid declaration.
Beginner habit
Build and protect your pure sequence before using jokers on other groups.
Do not break a nearly complete pure sequence unless you have a stronger replacement plan.
Quick answers
Can a printed joker be part of a pure sequence?
A printed joker can be used as its natural card value, but it cannot replace another missing card in a pure sequence.
Should beginners make a pure sequence first?
Yes. It is usually the safest first priority because many valid declaration rules depend on it.
