Had a meal at end of game (3)
I believe the answer is:
ate
'had a meal' is the definition.
'at end of game' is the wordplay.
'end of' suggests the final letters.
The last letter of 'game' is 'e'.
'at'+'e'='ATE'
(Other definitions for ate that I've seen before include "mischief-maker" , "upset > Greek goddess" , "Consumed food" , "Bolted" , "Munched" .)
