Helps her putt in tight game (4,3,7)
I believe the answer is:
hunt the slipper
'game' is the definition.
(hunt the slipper is a parlour game)
'helps her putt in tight' is the wordplay.
'tight' is an anagram indicator (tight can mean drunk).
'helps'+'her'+'putt'+'in'='helpsherputtin'
'helpsherputtin' with letters rearranged gives 'HUNT-THE-SLIPPER'.
(Other definitions for hunt the slipper that I've seen before include "party game?" , "What Prince Charming had to do" .)
