Airport City - Offline but can't be hacked?

[ambrosiany]

I've tried changing the coin and cash values and it never works. Has someone used GG to do this successfully? Please let me know, thank you so much for the help.

I've tried too. No success. It also has protection against lucky patcher, many attempts I got banned.

hmm..i think

i did hacked this game a  very very long time ago..

most are hackable but only in offline mode.

once you go online with hacked values..you will get ban.

as far as i can remember.(or its someone else i know)

there is a topic of this from a very long time ago in here but seem cant find anymore.
