Easter PIN
This app is a sort of brain teaser: there is 1 on 322 probability to get a right code, so you can try randomly or you can use some hidden suggestions all around the app. Youll soon understand... just maybe check the settings page, will you?
Totally, there are 32 correct codes and a combination of 10.000 possible codes. Good luck, agent.
P.S.: 7153.
