Every hand in tenpai involves some sort of wait pattern, or '''machi'''.  Various wait patterns are conveniently named to allow quick recognition of waiting tiles.  Likewise, players who recognize these patterns may also be able to select among them.

'''Jantou''' are the tile pairs to a mahjong hand.  Every hand, open or closed, requires at least one tile paired.  The pair must either be in the hand, or the hand must be waiting to complete the pair while in possession of four tile groups.  The latter forms the waiting pattern of [[tanki]] (pair wait).  In addition, certain pairings may generate [[fu]].  The tanki pattern generates fu, as well as with certain [[jihai|honor tiles]].

The last three examples are all open hands.  Both 4 and 5 may employ [[yakuhai]].  Example 4 definitely has a yaku, via the open call on the [[hatsu|green dragon]].  Example 5 could have a yaku, if the hand is seated west or the game is in the [[west round]].  The last example uses [[tanki|hadaka tanki]], by which four tile calls were used to achieve tenpai.  All that remains closed is a single tile, that needs to be matched with the exact same tile type.  However, example 6 does not have yaku as it stands.  It'll require [[haitei]], [[houtei]], [[rinshan]], or [[chankan]] to gain yaku.
