Game of golf a rep arranged (8)
I believe the answer is:
leapfrog
'game' is the definition.
(I know that leapfrog is a type of child\\u0027s game)
'golf a rep arranged' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'golf'+'a'+'rep'='golfarep'
'golfarep' is an anagram of 'LEAPFROG'.
'of' is the link.
(Other definitions for leapfrog that I've seen before include "Child's game of jumping over competitors" , "Children's game of jumping over each other" , "Advance by jumping over the opposition" , "Overtake in position" , "Jump over" .)
