Playing at Vegas and getting benefits (10)
I believe the answer is:
'benefits' is the definition.
(I've seen this before)
'playing at vegas and' is the wordplay.
'playing' is an anagram indicator.
'atvegasand' is an anagram of 'ADVANTAGES'.
'getting' acts as a link.
(Other definitions for advantages that I've seen before include "Gave a stand (anag.)" , "profits" , "Benefits" .)
