The game is a slot machine for android(android studio)

We need to make a game(slot machine) in the android studio. It should not be a webview. The design of the game is not interested. You need the simplest functionality with the "SPIN" button. When the application is downloaded, it checks the country. All countries except one go to the game. If the desired country, then there is a download of the webview with my link tds At the request specify cost and terms at once. Thank you.
