Practise this lesson

A joker gives you more ways to finish a group. Once you know where it belongs, you'll know when it can help.

Jokers need three or more matching tiles

Here's the rule to keep handy: a joker can replace a tile only in a group of three or more identical tiles. The joker counts toward that total.

ExampleCan you use a joker?
Two 6 Dots and a joker as a pungYes: the group counts as three 6 Dots.
Three 2 Bams and a joker as a kongYes: the group counts as four 2 Bams.
One 4 Crak and a joker as a pairNo: a pair has only two tiles.
2, 3, 4 as a runNo: the numbers are different.
NEWS or the digits 2026No: these are separate tiles, not an identical group.

A year hand can still use jokers in its pungs or kongs. The restriction applies to the separate digits spelling the year.

Kong of 2 Bams2 Bam2 BamJoker2 Bam
The joker counts as the fourth 2 Bam.

Choose where your joker helps

A natural tile is the actual tile a joker replaces. You may use a joker in an exposure even when you hold the natural tile.

In this hand, your three natural 8 Craks can join the discarded fourth. Using them leaves your joker free to help with the 2 Bams.

A discarded joker cannot be taken

Once you discard a joker, nobody can call it, even for mahjong. Check that your hand no longer needs it before letting it go.

Discarded jokerJoker
Once discarded, a joker cannot be called, even for mahjong.

Remember

Jokers work in matching groups of 3 or more. Never in singles or pairs. Never take a discarded joker.
