Hit the jackpot with emoticon illustrating wealth (4,4,5)

'hit the jackpot' is the definition.
I know nothing about this answer so I can't tell whether this works.

'emoticon illustrating wealth' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'emoticon' is 'comeinto' which is within the answer.
'wealth' could be 'money' (money is a kind of wealth) and 'money' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'with' is the link.

Can you help me to learn more?
