A card she played in party game (8)
I believe the answer is:
charades
'party game' is the definition.
(I've seen this before)
'a card she played' is the wordplay.
'played' is an anagram indicator.
'a'+'card'+'she'='acardshe'
'acardshe' anagrammed gives 'CHARADES'.
'in' is the link.
(Other definitions for charades that I've seen before include "Game in which answers are acted out" , "Guessing game where words are acted out" , "Party guessing game" , "Miming parlour game" , "Miming games" .)
