Can I call a discard if all I have to go with it is Jokers?

Yes. The discard you call is the natural tile, and Jokers from your hand may fill every other place in the group. Two Jokers and a called Five Dot make a perfectly legal pung. The call only works for a pung, kong, quint or sextet, never for a single or a pair, and the group must fit a line on the current card.

The thrown tile is your natural

A great many players believe they need at least one real tile of their own before they may speak up for a discard. They do not. The League sets no minimum number of naturals in a pung, a kong, a quint or a sextet. The tile being thrown supplies the one natural the table needs to see, and your Jokers supply the rest.

So if a Five Dot lands in the center and you are holding two Jokers, call it. Lay the Five Dot and the two Jokers face up on top of your rack, discard, and play moves on to your right. With three Jokers you may make a kong the same way, and with four, a quint.

Only for a group of three or more

The call is for a pung, kong, quint or sextet of like tiles, and nothing else. A Joker may never stand in a single or a pair, so a lone natural and a lone Joker cannot become a pair on the rack, and a discard called for that purpose is an incorrect exposure. The one exception to calling for a pair is the fourteenth tile that completes Mahjong, and even then the pair must be two naturals.

The group must also fit a line on the current card. Three tiles that make a legal pung but belong to no hand you could play are an exposure that matches nothing, and a hand showing one can be called dead.

Why the card allows it

There are only four natural copies of any number, wind or dragon. That arithmetic is the reason a quint must include at least one Joker, and it is the reason the rules never ask you to supply naturals of your own. Flowers are the exception to the count, since eight of them exist, but the principle is the same.

An exposure with no natural in it at all is the one thing you cannot make, and the reason is simple: an exposure only happens when you call a discard, and a discarded Joker is dead and can never be called. The called tile is always the natural. In the hand you show at Mahjong, by contrast, a pung held behind the rack may be all Jokers.

Before you call, count the cost

Every Joker you lay face up is on offer to the whole table. Any player holding a natural Five Dot may, on their own turn, trade it into your exposure and walk away with your Joker. An exposure of one natural and two Jokers is two Jokers waiting for a taker.

Remember too that a call is a commitment. Once the called tile is racked, it stays with you, and once you discard, the shape of the exposure is fixed for the rest of the hand. Call with Jokers when the group truly belongs to the hand you are building, not simply because the rule permits it.
