The union game (3)
I believe the answer is:
tie
I believe this is a double definition.
'the union' is the first definition.
(thesaurus)
'game' is the second definition.
(I've seen this before)
(Other definitions for tie that I've seen before include "Draw for neckware" , "Draw - connection" , "Knot; link" , "Bond; neckwear" , "Secure (with string)" .)
