Parlour game had races, unfortunately (8)
I believe the answer is:
charades
'parlour game' is the definition.
'charades' can be an answer for 'game' (charades is a kind of game). I'm not certain of the 'parlour' bit.
'had races unfortunately' is the wordplay.
'unfortunately' indicates anagramming the letters.
'had'+'races'='hadraces'
'hadraces' with letters rearranged gives 'CHARADES'.
Can you help me to learn more?
(Other definitions for charades that I've seen before include "Game in which answers are acted out" , "Miming parlour game" , "Miming games" , "Games like this" , "Guessing game where words are acted out" .)
