My son is learning to play poker. I don't mind him learning to bet, but every app I've looked at in the App Store has in-game purchase options for chips and other items that I'm not really interested in. Some of these get expensive, too, like $99 for 10,000 chips!! I just want a simple app that will let him play something like 5-card stud without in-app purchases being flashed on screen every 5 seconds. I don't mind paying for the app itself, but this is for a kid - not for an adult looking to rake up virtual (or real) cash. Any suggestions??
