My 5 year old son came to me and said Dad I was able to purchase this app. I told him there's no way with authentication feature turned on son you shouldn't be able to. I went hit the purchase button thinking it would ask for my pin & it ordered a $9.99 pack SUPRISE! We had a phone update & our authentication feature was some how switched off. The developers refunded us in full (When Google said No refunds) they're pros at what they do, I would recommend them to parents for games & Rad Customer(me)Service.
From the screenshots it looked odd, but it gives you something skillful to do during the typically boring part of train games. Give it a try.
