Game ending in draw? (7)
I believe the answer is:
lottery
'game ending in draw?' is the definition.
(a lottery is a prize draw)
'in draw?' is the wordplay.
I cannot really understand how this works, but
'draw?' could be 'lot' (synonyms) and 'lot' is located in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for lottery that I've seen before include "The random drawing of numbers from a drum" , "Chance draw" , "Risky operation" , "Chance competition" , "Game in which prizes are awarded by chance" .)
