Game no good: yet medal results (4)
I believe the answer is:
gong
'yet medal results' is the definition.
I can't judge whether this defines the answer.
'game no good' is the wordplay.
'game' becomes 'go' (go is a board game).
'no good' becomes 'ng' (abbreviation).
'go'+'ng'='GONG'
(Other definitions for gong that I've seen before include "Medal (sl.)" , "Sound it, for dinner say" , "Medal; forty down" , "Source of summons" , "Beat this" .)
