Newlywed collecting last of stuffing for game (6)
I believe the answer is:
bridge
'for game' is the definition.
(card game)
'newlywed collecting last of stuffing' is the wordplay.
'newlywed' becomes 'bride' (newlywed woman).
'collecting' indicates putting letters inside.
'last of' says to take the final letters.
The final letter of 'stuffing' is 'g'.
'bride' placed around 'g' is 'BRIDGE'.
(Other definitions for bridge that I've seen before include "Crossing point" , "indoor game" , "Where four hands are needed" , "''Like a ... over troubled water'' (Simon and Garfunkel)" , "Viaduct" .)
