Question 1 of up to 1

Is the Joker filling a spot in a group of three or more identical tiles — a pung, kong, quint, or sextet?

Read every possible ruling for this situation

Joker ok

Yes — Jokers belong in groups of three or more

Standard rule
Yes. A Joker may take the place of any tile in a pung, kong, quint, or sextet — numbers, winds, dragons, or flowers — and a group may hold any number of Jokers, even all of them, while it is concealed in your hand. An exposure made from a discard needs that one natural tile and may otherwise be all Jokers. This is true in exposed and concealed hands alike.
Why
Groups of three or more identical tiles are exactly where the card allows Jokers; that is their whole job.
Common house rules
None that we know of. This one is played the same way at nearly every table.

If your table agreed on a house rule before the game, that rule wins.

No joker

No — never in a single or a pair

Standard rule
No. A Joker can never be a single tile or either tile of a pair. That includes the groups on the card that only look like a set but are really singles and pairs printed together — NEWS, a year such as 2026, and the like. Singles-and-pairs hands therefore use no Jokers at all. A Joker placed in a pair or a single makes the hand incorrect; if it is exposed or declared that way, another player may call the hand dead.
Why
Pairs and singles are meant to be the hard part of a hand; letting Jokers fill them would flatten the whole card.
Common house rules
Some social groups invent “super Jokers” or treat blank tiles as wild cards that can fill a pair. Those are table inventions, not the standard; everyone should know before the deal.

If your table agreed on a house rule before the game, that rule wins.
