A game outcry (5)
I believe the answer is:
bingo
This might be a double definition.
'a game' is the first definition.
(bingo is a game)
'outcry' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for bingo that I've seen before include "House!" , "I've completed my card!" , "Game of chance" , "Game in which "two little ducks" might be called" , "Housey-housey" .)
