Crossword Genius

Female condemned rich uni mates, they're often in casinos (5,8)

I believe the answer is:

fruit machines

I'm a little stuck... Click here to teach me more about this clue!

'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".)

I've seen this clue in The Telegraph.
