Some game Antony had in mind? (5)
I believe the answer is:
meant
'had in mind?' is the definition.
(mean can mean to intend or have in mind)
'some game antony' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'MEANT' is hidden within 'game antony'.
(Other definitions for meant that I've seen before include "planned" , "Intentional" , "represented" , "Intended, had in mind" , "Implied" .)
