Pans terrible game (4)
I believe the answer is:
snap
'game' is the definition.
(card game)
'pans terrible' is the wordplay.
'terrible' indicates anagramming the letters.
'pans' with letters rearranged gives 'SNAP'.
(Other definitions for snap that I've seen before include "Break suddenly and abruptly" , "Break sharply like dry twig" , "sometimes preceded by brandy" , "Snarl at - photograph" , "Crack; bite" .)
