Reddit – Dive into anything
Many popular mobile games make you pay a fee or wait a certain time in in order to continue playing. Examples include Batman Arkham Origins, Candy Crush Saga and Jelly Splash.
You can remove these annoying artificial waiting times / payments by simply changing the time setting on your device. Once your stamina or whatever is depleted, change your phones date one day ahead and get your stamina back for free. You can then change the time back to normal, but your stamina will still be there. Enjoy.
