Cash
The easy one.
Get together some cash (30+, this makes the process faster)
Search for your exact amount of cash (if you have $300, search 300)
Play a level, gaining extra cash
Refine your search to the new exact amount of cash
Keep doing the above until you narrow it down to a few results, then change the values as you see fit.
Tickets
The harder one.
Open the game, and put your system clock forward one day
Claim your daily prize
If the prize is not a ticket, repeat step 1 and 2 (until you have 3 tickets or more)
Search for your exact amount of tickets (if you have 3, search 3)
Repeat steps 1, 2, and 3 to increase your ticket collection by 1
Refine your search to the new exact amount of tickets
Keep doing the above until you narrow it down to a few results, then change the values as you see fit.
Result
Hmm, which option...
