Our prize wheel is open from the time the doors open until 15 minutes prior to the live auction.
We usually have at least 2 people running the both, 1 to take the money and supervise the spinning and the other to help give out prizes to the winners. When the wheel lands on a category we have a list typed of all prizes in that category which the winner can choose from, we simply cross out the prize that is chosen. Of course some items have to be individually placed on the wheel such as cash prizes or special prizes. For example some of our categories are Dinner Out, Live Shows, Home Bake Goods, Pick a Camp, Sporting Events, Auto Maintenance, Dinner and a Show, School Spirit Items, Etc. We have found it easier to group our prizes into categories so we are not constantly changing the flags. Usually people will spend $20 at a time and then move aside to let the next person spin. We always have a line at the prize wheel.
We place flags that say thank you for supporting our school on every other space, then fill the rest of the spaces with prize flags. We have a used a prize wheel at our dinner/auction for the past 3 years.
