In parentheses on the card, it says “like pungs” – what does that mean?
It means that the pungs must be alike. They must be of the same number value AND the same suit. A pung of 1B is not “like” a pung of 1D for example. They may both be represented on the card by the number “1,” but they are only “like” one another if they are not just the same number but also the same color (suit).
