Hard work followed by drink and game (9)
I believe the answer is:
Here is my best explanation:
'game' is the definition.
(hopscotch is a kind of game)
'hard work followed by drink' is the subsidiary indication.
'hard' becomes 'h'.
'work' becomes 'op' (common abbreviation for 'opus').
'followed by' means one lot of letters go next to another.
'drink' becomes 'scotch' (Scotch is an example**).
'and' is the link.
(Other definitions for hopscotch that I've seen before include "Children's game with squares on ground", "Jumping game", "Traditional children's game", "Playground game" and "Children's pavement game".)
