Game and trifle (9)
I believe the answer is:
bagatelle
This clue is a double definition.
'game' is the first definition.
(I know that bagatelle is a type of table game)
'trifle' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for bagatelle that I've seen before include "Trifling matter" , "Trifle; pinball game" , "piece, one for piano" , "lovely trinket" , "shooting game" .)
