There are some offers there for mobile game download and complete some levels. So I want to know after downloading these games we need to play with the keep mobile internet on? because we can play some games offline.
It depends on the tasks. You can get high rewards when a task is high the difficulty especially if it takes a day to complete a task. Most downloaded apps are online so it really needs the internet when used. I rarely find a downloadable app or game that the internet doesn't need, sometimes not really.
