I am developing an arcade style, ios for iphone, app in which one app will contain a number of casual games and you pick the game you wish to play via a menu. I recently read about an app which had upwards of a few hundred apps in one app. In 2014 the app developers of this app announced that their app was removed by Apple due to Apple no longer supporting "apps within an app". I see other arcade style apps that contain many games in one app. I need to understand the Apple policy on what is acceptable regarding many games in one app and when the policy is in violation. I would appreciate any policy information on this topic so that I can avoid any problems and be in compliance with an arcade style app.
Policy on "apps within an app"
Are you sure the removed app didn't violate 10.4 in the review guidelines?

Just know that Apple tends to define and wield app store black box 'policy' on the fly, so there isn't much to be learned here in the forums that will promise your app will/won't be accepted/rejected.
