A picker wheel, not a coupon wheel
Many “spin to win” wheels for websites are pop-ups that trade a discount code for an email address. This one asks for nothing: no form, no prizes, no stored addresses. It picks at random from the list on the screen, and nothing your visitors type ever leaves their browser.
Which size to pick
Small (360 pixels wide) fits a blog sidebar. Medium (480 pixels) suits most pages. Large (760 pixels) shows the list next to the wheel along with the full button bar, which works best on a page built around the game or on a projected screen. On phones, every size narrows to fit the screen.
A wheel that is already filled in
Ready-made wheels keep their list in their widget. Open the country wheel or the chore wheel, tap Widget at the bottom left and copy the code: your visitors have nothing to type.
