Do NOT BUY. This app is really cute and looks clean and fantastic. My husband downloaded this on the kids tablet and paid $6.99 for more content. The purchase went through, they took the money but the content WILL NOT UNLOCK. I read reviews after the fact and found that every reviewer who paid to unlock more numbers had the SAME problem. I don't think the developer actually created the extra content and is stealing people's money. Sounds crazy, but if the shoe fits.
