Lost me cash in terrible contraptions (12)

I believe the answer is:

slotmachines

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

'contraptions' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'lost me cash in terrible' is the wordplay.
'terrible' indicates anagramming the letters.
'lost'+'me'+'cash'+'in'='lostmecashin'
'lostmecashin' anagrammed gives 'SLOTMACHINES'.

Can you help me to learn more?

I've seen this clue in The Irish Independent.
