Sundae is just a fancy way of saying ice cream scoops in a bowl. Click or tap on the ice cream balls to eat them. Once you begin the process of eating the ice cream, the timer starts to countdown. If you can't finish eating the ice cream before the time is up, you'll have to start over from the top and try eating the ice cream again. Since the ice cream is virtual, there's no need to worry about your stomach hurting from eating too much.
