Croupier to wander around island (6,4)
I believe the answer is:
puerto rico
'island' is the definition.
(Puerto Rico is an example)
'croupier to wander' is the wordplay.
'wander' indicates an anagram.
'croupier'+'to'='croupierto'
'croupierto' anagrammed gives 'PUERTO RICO'.
'around' acts as a link.
(Other definitions for puerto rico that I've seen before include "Caribbean island" , "Self-governing American commonwealth in the Caribbean" , "WI island associated with the US" , "Caribbean location" , "Well-filled country" .)
