Game by the fireside (5)
I believe the answer is:
poker
'game' is the definition.
(I know that poker is a type of card)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for poker that I've seen before include "Epitome of stiffness" , "declared to be stiff" , "Popular gambling game with much bluffing" , "Ashes stirred by this" , "Fire-raiser" .)
