Satisfactory in each game (5)
I believe the answer is:
poker
'game' is the definition.
(I know that poker is a type of card game)
'satisfactory in each' is the wordplay.
'satisfactory' becomes 'ok' (similar in meaning).
'in' indicates putting letters inside.
'each' becomes 'per' ('per' can mean for each).
'ok' inserted within 'per' is 'POKER'.
(Other definitions for poker that I've seen before include "Fire prodder; game" , "See 1" , "Epitome of stiffness" , "Fire prod; game" , "Stiff rod; card game" .)
