At darts, best place for a score? (3)
I believe the answer is:
top
'a score?' is the definition.
The answer and definition can be both shapes as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'at darts best place for' is the wordplay.
I cannot really see how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
A single letter 'p' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for top that I've seen before include "Most successful" , "Summit or spinning toy" , "Pinnacle" , "Better" , "Spinner" .)
