To play spin wheel, just click the 'Play' button. After the spinning stopped, the winner will be displayed.
After the winner is displayed, the 'Remove Winner Name' button will appear so you can remove the winner. You can display back all the removed names in the current set of names by clicking the 'Reset Names' button.
To customize the names, just click on the 'Name Sets' button at the top. A pop-up box will appear for you to change the name. Click 'Save' button when you're done. By default, the spinwheel will display the most popular names of both male and female.
