This is my own version of a fortune wheel minigame. The gems you can see on the screenshot below will rotate as expected after you hit the OK button. Later on it will show you your prize. After you collect it, it will show up on the window on the right hand side of the screen as an icon. You may collect more prizes the more attempts you get.
Just remember I didn't provide the gems you see below. Use your own icons if possible, you just need 10 of them.
