Suppliers of pork and game (10)
I believe the answer is:
backgammon
'game' is the definition.
(backgammon is a kind of game)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for backgammon that I've seen before include "Dice and counter game" , "Players' race to clear tables" , "Board game played with dice" , "sedentary activity" , "Dicey business" .)
