Top darts score? (6)
I believe the answer is:
twenty
This clue could be a double definition.
'top darts' is the first definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'score?' is the second definition.
('twenty' can be a synonym of 'score')
Can you help me to learn more?
(Other definitions for twenty that I've seen before include "No longer a teenager" , "Figure" , "Score, XX" , "made by Q on a light blue square" , "Number" .)
