If one of the questions in the wheel has already been picked and you don’t want it to get selected again, you can use the “Hide Slice” or “Remove Slice” options. If you use the “Hide Slice” button, you will be able to temporarily remove the question from the list. It will come back once the page is refreshed. On the other hand, by using the “Remove Slice” button, you will be able to remove the selected slice permanently from the wheel.
