Break for a game of cards (4)
I believe the answer is:
snap
I believe this is a double definition.
'break' is the first definition.
(I know that snap is a type of break)
'game of cards' is the second definition.
(I've seen this before)
'for a' acts as a link.
(Other definitions for snap that I've seen before include "Photograph - card game" , "Sudden break" , "Bite at or utter angry words" , "Simple card game - gotcha!" , "Quick photograph - impression" .)
