When you turn on "Remove Once Chosen" on the settings screen, the mode changes so that each chosen slice is removed.
For example, if you create a wheel with 4 slices (1, 2, 3, 4) and spin it, and 1 is chosen, then on the next spin "1 is removed once chosen", leaving a wheel with only the 3 slices 2, 3, and 4.
This way, you can enjoy a style of play where chosen slices drop out one after another.
It works well for win-and-out or lose-and-out games, so please give it a try.
