Fire controller for game (5)
I believe the answer is:
poker
'game' is the definition.
(poker is a kind of game)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for poker that I've seen before include "Fire-iron" , "One of many irons in the fire" , "Fire-raiser" , "Rod liable to become heated" , "Pushy person" .)
