Hi Livvy. Everything in the "Coins and More!" section of the store are In-App Purchases that you can buy to give your little family a boost. The Brokerage Account, Food Club, Health Plan and Lucky Rock will also remain through the generations.

Tap the item you wish to purchase. A conformation dialog will pop up confirming your purchase. Tap "Buy" to buy or "Cancel" to cancel. If you are not already signed into iTunes, you will be prompted for your Apple ID and password to complete the transaction. After your purchase has downloaded, completely close and re-open the app. The ads will be gone forever. I hope this helps.
