Break game (4)
I believe the answer is:
snap
This clue is a double definition.
'break' is the first definition.
(I know that snap is a type of break)
'game' is the second definition.
(card game)
(Other definitions for snap that I've seen before include "Family helper" , "Picture" , "Unpremeditated - bite" , "Crack - shot" , "Spell of cold weather and card game" .)
