I believe the answer is:

bridge

I'm a little stuck... Click here to teach me more about this clue!

'game' is the definition.
(card game)

I cannot understand how the remainder of the clue works.

(Other definitions for bridge that I've seen before include "Game of cards" , "spanner" , "Join" , "Hard ridge on the nose" , "Bony upper part of nose; card game" .)

I've seen this clue in The Times.
