Hit the jackpot and fled (4,3)
I believe the answer is:
took off
'hit the jackpot and fled' is the definition.
I can't tell whether this defines the answer.
'and fled' is the wordplay.
'and' becomes 'too'.
'fled' becomes 'koff' (I can't explain this - if you can you should give a lot more credence to this answer).
'too'+'koff'='TOOK OFF'
Can you help me to learn more?
(Other definitions for took off that I've seen before include "Became popular" , "became a success" , "Deducted" , "Imitated in an amusing way" , "as an impressionist?" .)
