Game of golf, par broken round course's last (8)
I believe the answer is:
leapfrog
'game' is the definition.
(leapfrog is a kind of game)
'golf par broken round course's last' is the wordplay.
'broken' is an anagram indicator.
'round' means one lot of letters goes inside another.
'last' indicates one should take the final letters.
The last letter of 'course' is 'e'.
'golf'+'par'='golfpar'
'golfpar' with letters rearranged gives 'lapfrog'.
'lapfrog' placed around 'e' is 'LEAPFROG'.
'of' is the link.
(Other definitions for leapfrog that I've seen before include "Advance by jumps" , "bound over" , "Game in which players vault over each other" , "Overtake in position" , "Children's game of jumping over each other" .)
