There are multiple ways to cheat in money on Case Clicker.
Option 1:
Go onto Case Clicker.
Make sure you have upgrades such as "Money per second" and "Offline Generating Time".
Upgrade these as much as possible for bigger amounts of money.
Go off of Case Clicker.
Go to your device's settings.
Turn the time forward depending on your "Offline Generation Time"
Go back onto case clicker.
It will welcome you back :)
Option 2:
Once you have good enough items, and trades unlocked (I believe it costs $750) on 2 different devices with different game-centers...
Go to Settings
Game Center (Make sure you are logged in)
Cloud Saves
And tap on Save Game.
Wait 8 hours (you can not turn the time forward on your device for this.)
Trade all of the items you would like to duplicate in (from your main account).
Look at how much money that it is worth.
Go onto a calculator and divide that number by 3, and then multiply it by 2.
That is the price that you must pay on your secondary account (not your main account)
Keeping repeating the trading process until you have transferred lots of money from your main account to your secondary account.
Then go to Settings
Game Center (Once again, make sure you are logged in)
Cloud Saves
Load Game
This will load back all of the items that you traded to your second account.
You can trade them back to your main account or keep them on your secondary account.
You can sell the items for money, especially if you are trading Dragon Lores, etc.
WARNING:
ANY ITEMS IN YOUR MAIN ACCOUNT THAT CAME FROM YOUR SECONDARY ACCOUNT WILL BE DELETED UPON LOADING THE CLOUD SAVE!!!
BE WARNED!!!
I hope this helps! :D
