Indiana Online Gambling Laws

[jeep83]

I have been playing cash competitions on gsn.com/World Winner. Lately I have been hearing a lot about states having laws restricting gambling. I have not played any card games but there are games such as Diner Dash, Big Money, and Paint Buckets, among others that I have played. This, of course, involves paying an entry fee and then if won, receiving a monetary prize. The site prevents me from playing card games because it says they are not permitted in my location. I have been playing the other games I mentioned though. I am located and playing in Indiana. Is playing these cash competitions considered illegal in Indiana? If so, what should I do now?
