"Game, ___, match!" (3)
I believe the answer is:
set
I believe this clue is a double definition.
'game' is the first definition.
(thesaurus)
'match' is the second definition.
(I know that match is a more specific form of set)
(Other definitions for set that I've seen before include "Place - become rigid - adjust - group of tennis games - fixed - clique - fall beneath the horizon" , "Mount (gem); scenery" , "Put down the group of games" , "Badger's burrow" , "Put down tennis games" .)
