Lines And Values
A card line describes a complete hand and its point value. Your job is to identify which lines your tiles can realistically reach.
Groups
Lines are built from singles, pairs, pungs, kongs, quints, flowers, winds, dragons, and suit runs. Similar groups across multiple lines create flexible starts.
Open Or Concealed
Some hands allow exposed groups and some do not. If a hand is concealed, claiming a discard for exposure can make that line invalid.
