No big game? (5)
I believe the answer is:
bingo
'no big game?' is the definition.
'bingo' can be an answer for 'game?' (I've seen this before). I'm not certain of the 'no big' bit.
'no big game?' is the wordplay.
'game?' indicates an anagram (solving anagrams is a game).
'no'+'big'='nobig'
'nobig' with letters rearranged gives 'BINGO'.
Can you help me to learn more?
(Other definitions for bingo that I've seen before include "Game of chance" , "House!" , "Game in which "two little ducks" might be called" , "game requiring little ability" , "Number game" .)
