Question regarding if app actions constitutes a violation

Hi everyone, I have a question for knowledgable app developers or apple experts. Lets say there is an app in Apple Store, for sake of discussion lets say its a Bingo app. As part if the app they allow in-app purchases for lets say "fake" bingo cards, zero value rewards.

However, when clicking the store to purchase those zero value rewards there is a pop-up that says "Want to play for real money" which then gives you the option to click it and then points to the app's website which allows you to then purchase sweepstakes coins which can be converted into monetary value. Is this authorized behavior by Apple from an app perspective? Are app developers allowed to push you outside the app for purchases etc?

For clarity, the in app purchases are only for fake bingo cards, zero redemption value. Only website out of app purchases allow sweepstake coins for redemption. Is the fact that the content available for purchase is different outside of the app indicative of the developer knowing that the sweepstakes portion is a violation of TOS for purchuse inside the in-app environment?
