Game from oil era, it’s newly ordered (9)
I believe the answer is:
solitaire
'game' is the definition.
(I know that solitaire is a type of card game)
'oil era it's newly ordered' is the wordplay.
'newly ordered' indicates anagramming the letters (in a new order).
'oil'+'era'+'its'='oileraits'
'oileraits' is an anagram of 'SOLITAIRE'.
'from' is the link.
(Other definitions for solitaire that I've seen before include "Board game played by one person" , "Diamond; game for one" , "Patience game" , "recluse" , "Game for one person - single gem" .)
