Wonderful game is played (4)
I believe the answer is:
mega
'wonderful' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'game is played' is the wordplay.
'is played' is an anagram indicator (letters playing around).
'game' anagrammed gives 'MEGA'.
Can you help me to learn more?
(Other definitions for mega that I've seen before include "Informally great or large" , "Very large (prefix)" , "As brilliant" , "wicked" , "Fantastic!" .)
