Using the wheel as the prize list, not just the entrant list
Most drawing tools assume you're picking a winner from a list of people. A prize wheel flips that: the entries on the wheel are the prizes themselves (gift card, free coffee, extra ticket, 'try again') and a person spins to see what they get. It's a common setup for booth events, employee rewards, and party games.
Because Spinzelvo doesn't care what your entries represent — just that they're text labels on a wheel — it works equally well either way. List prizes with different quantities (duplicate a common prize to make it more likely, or list a rare grand prize just once) and spin per participant.
