Female condemned rich uni mates, they're often in casinos (5,8)
I believe the answer is:
fruit machines
'often in casinos' is the definition.
I know nothing about this answer so I can't judge whether this works.
'female condemned rich uni mates' is the wordplay.
'female' becomes 'f' (abbreviation).
'condemned' indicates anagramming the letters.
'rich'+'uni'+'mates'='richunimates'
'richunimates' is an anagram of 'ruitmachines'.
'f'+'ruitmachines'='FRUIT MACHINES'
'they're' acts as a link.
Can you help me to learn more?
(Another definition for fruit machines that I've seen is " One-armed bandits".)
