Hard work followed by drink and game (9)
I believe the answer is:
hopscotch
'game' is the definition.
(hopscotch is a kind of game)
'hard work followed by drink' is the wordplay.
'hard' becomes 'h'.
'work' becomes 'op' (abbreviation for opus).
'followed by' means one lot of letters go next to another.
'drink' becomes 'scotch' (Scotch is an example**).
'h'+'op'+'scotch'='HOPSCOTCH'
'and' is the link.
(Other definitions for hopscotch that I've seen before include "Children's pavement game" , "Playground game" , "Traditional children's game" , "kids jump about in it" , "Children's game with squares on ground" .)
