My daughter used my card to purchase this game. It charges me every month and I can not figure out..

This is a community help site so we do not have any control over game payments.

Assuming the game was obtained from an app store. Google Play or iTunes App Store then you should be able to find any subscriptions or recurring payments by accessing your account on that store. There should be an app on your device for this. You should be able to cancel it there.

You might be able to get more specific advice from the game developer - Microfun Ltd.
