Very good Las Vegas game, but learner's missed out in spin (9)
I believe the answer is:
pirouette
'spin' is the definition.
(I know that pirouette is a type of spin)
'very good las vegas game but learner's missed out' is the wordplay.
I cannot quite understand how this works, but
'good' could be 'pi' (old-fashioned term for pious) and 'pi' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for pirouette that I've seen before include "Dancer's twirl" , "Whirl round on one's toes" , "bit of dancing" , "Tore up tie (anag) - spin" , "Twirl like a ballerina" .)
