Please note that this option becomes available starting with level 10.

How do I activate the subscription?

It is quite simple! Just tap on the energy bar at the top and then tap on this icon:

You can also access the same section in the bank if you tap on the "+" sign to the right of the energy bar:

In the window that opens, you will see the subscription details and the pricing options (weekly, monthly, yearly subscription). Depending on the option that you choose, you will be charged for the subscription automatically at the end of the subscription period (once a week, once a month, or once a year).

Choose the subscription plan that you prefer and tap "Start now".
