A double-dealing game (4)
I believe the answer is:
snap
This could be a double definition.
'a double-dealing' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'game' is the second definition.
(card game)
Can you help me to learn more?
(Other definitions for snap that I've seen before include "Still" , "Speak irritably; break" , "Quick photograph - impression" , "Informal photograph" , "Picture" .)
