Wonderful game was played (4)
I believe the answer is:
mega
'played' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'wonderful game' is the wordplay.
'game' can be anagrammed to 'MEGA'.
Though, I'm unsure how this is indicated.
'was' acts as a link.
Can you help me to learn more?
(Other definitions for mega that I've seen before include "Fantastic!" , "Smashing" , "wicked" , "As brilliant" , "Great American" .)
