If you've made purchases in the game or other applications before, the following reasons may explain why you can’t make a purchase:

1. Bad internet connection. We recommend using Wi-Fi or at least a 3G/4G connection.
2. Temporary problems with the application store. All in-game purchases are processed by the store where the game was downloaded from, so there is a chance the store is overloaded and unable to process your request. In that case, just wait several minutes and try again.

If you've never made purchases in the game or other applications, the problem may be one of the following:

1. Incorrect payment information. The easiest way to fix that is to cancel the payment method and start over.
2. Unsupported payment method. It may be that the payment method you want to use is not supported by the application store. The list of available payment methods can be found in the section of the Apple customer support websites.

If the problem still exists, please contact the application store customer support.
