Definition
Like Numbers is the section of the card built around one number repeated across the suits, such as pungs or kongs of the same number in craks, bams and dots.
It is the first thing to count in a deal: three or four copies of one number across suits is a stronger signal than any run. Jokers help here because the sets are pungs and kongs.

See it on real tiles: the coach reads any hand and names its direction, free, at the free read. Members get the coach on call for their own games.
