How to restore balls?

In order to restore a ball you need to choose it in your Arsenal, then tap the Setup button, and after that tap the Restore button. You can see the cost of the restoration above this button.
If you purchase the Gold Card your balls will be prevented from wear and tear for as long as the Card is activated.

You can not restore only the first "Noname" ball. Its parameters are low and it doesn't wear down. If you have a problem with another ball please submit a request and provide us with more information.
