This compiler rejected game's uses (7)

Ross

I believe the answer is:

employs

'uses' is the definition.
(I know this)

'this compiler rejected game's' is the wordplay.
'this compiler' becomes 'me' (the person who is writing these clues).
'rejected' says the letters should be written backwards.
'game's' becomes 'ploy's' (both can mean a trick).
'me' in reverse letter order is 'em'.
'em'+'ploys'='EMPLOYS'

(Another definition for employs that I've seen is " Uses or gives job to".)

I've seen this clue in The Telegraph.
