Board game roundly omitting content that's graphic (4)
I believe the answer is:
gory
'that's graphic' is the definition.
(thesaurus)
'board game roundly omitting content' is the wordplay.
I cannot quite understand how this works, but
'board' could be 'go' (go board is a kind of board) and 'go' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gory that I've seen before include "Violent; bloody" , "Horrific" , "Maybe gruesome" , "Bloodstained" , "Grisly" .)
