Your app will be available under your chosen name, with your app icon, from your developer account on the App Store and Play Store. You decide if the app itself is available for free or if customers need to pay via in-app purchases to download it.
You decide how your customers access your content. Keep everything visible and accessible in the app, or opt to lock certain games or tours, restricting access to only those with an invitation code (code or QR codes) or in-app purchases.
