Hard work is followed by whisky and a game (9)
I believe the answer is:
hopscotch
'a game' is the definition.
(hopscotch is a kind of game)
'hard work is followed by whisky' is the wordplay.
'hard' becomes 'h'.
'work' becomes 'op' (abbreviation for opus).
'is followed by' means one lot of letters go next to another.
'whisky' becomes 'scotch' (Scotch is an example).
'h'+'op'+'scotch'='HOPSCOTCH'
'and' is the link.
(Other definitions for hopscotch that I've seen before include "Jumping game" , "Traditional children's game" , "child's play" , "Children's pavement game" , "childish amusement" .)
