Go across for game (6)
I believe the answer is:
bridge
This clue is a double definition.
'go across' is the first definition.
(bridge can mean to go across)
'for game' is the second definition.
(card game)
(Other definitions for bridge that I've seen before include "Overpass" , "Card game for four players" , "Hard ridge on the nose" , "spanner" , "Span, connecting structure" .)
