Part of nose required for game (6)
I believe the answer is:
bridge
This clue is a double definition.
'part of nose' is the first definition.
('bridge' is part of 'nose')
'for game' is the second definition.
(card game)
'required' acts as a link.
(Other definitions for bridge that I've seen before include "may involve suspension" , "Span of popular card game" , "Overpass" , "Card game; structure" , "Join" .)
