Can a Joker be used in a pair or a single?

No. A Joker may stand only inside a group of three or more identical tiles, which means a pung, a kong, a quint or a sextet. It can never sit in a single or in a pair, and it can never fill a place in NEWS, in a year such as 2026, or in a run of different numbers. If a line is built entirely from singles and pairs, no Joker touches it anywhere.

The rule, and the shape of it

Three identical tiles is where a Joker becomes legal, and everything above three stays legal. A pung takes a Joker, a kong takes a Joker, and a quint or a sextet not only takes one but requires it, because only four naturals of any tile exist and a quint needs five. A pair is two. Two is not three. That is the whole of it.

The confusion usually comes from the word pair itself, because a pair is two matching tiles and a pung is three matching tiles, and it feels as though the same logic ought to stretch across both. It does not. The line is drawn at three and it does not move.

Whole lines are closed to Jokers, not just single spots

A year is a string of different numbers. NEWS is four different winds. A consecutive run is a string of different numbers in order. None of those is a group of identical tiles, so none of them takes a Joker in any position, not even in the one place you happen to be missing a tile.

Follow that far enough and you reach the Singles and Pairs section, where every group on the line is a single or a pair. A hand of that shape cannot accept a Joker anywhere at all. It is jokerless by its own structure, which is part of why those lines pay what they pay. The doubling that rewards finishing an ordinary hand without Jokers does not apply there, because there was never a Joker to do without.

What the rule does to your play

It changes what a Joker is worth to you, hand by hand. If you are building a line with two kongs on it, a Joker in your rack is close to a free tile. If you are building a line of singles and pairs, that same Joker is dead weight and you are gathering fourteen real tiles by yourself.

It also changes what you can call. A discard may be claimed to complete a pung, a kong, a quint or a sextet, and never to complete a single or a pair, with one exception: the fourteenth tile, the one that wins. So a hand that needs a pair is a hand that waits on the wall, or on that one last discard, and no Joker is coming to rescue it.

The mistake this rule is guarding against

The costly version is laying a Joker down inside an exposure where it does not belong, because an exposure that is not a legal group of identical tiles is an incorrect exposure, and an incorrect exposure is one of the plainest reasons a hand gets called dead. Those tiles sit face up on your rack for the rest of the hand, so anybody at the table can check the shape against the card at their leisure.

Look before you lay. Count the tiles in the group you are about to expose, and if the answer is one or two, the Joker stays in your hand.
