Game spinster (3,4)
I believe the answer is:
old maid
I believe this clue is a double definition.
'game' is the first definition.
(I know that Old maid is a type of card game)
'spinster' is the second definition.
(synonyms)
(Other definitions for old maid that I've seen before include "never taken from the shelf?" , "Spinster - card game" , "Elderly single woman - card game" , "Pejorative term for elderly unmarried woman" , "Miss" .)
