Loop back for a game (4)
I believe the answer is:
pool
'game' is the definition.
(I know that pool is a type of table game)
'loop back' is the wordplay.
'back' shows that the letters should be reversed in order.
'loop' in reverse letter order is 'POOL'.
'for a' acts as a link.
(Other definitions for pool that I've seen before include "Put in common fund; (pub) game" , "stakes" , "Small body of still water" , "Mere - game" , "Ball game - piece of water" .)
