The difference between sweepstakes and giveaway lies primarily in the method of entry and the selection of winners. Sweepstakes typically require participants to enter by providing personal information or completing specific tasks, with winners chosen randomly from all entries. In contrast, a giveaway often involves simpler participation, such as following social media accounts or sharing posts, with winners selected based on criteria like creativity or engagement. Understanding the difference between sweepstakes and giveaway can help participants choose the right opportunities to maximize their chances of winning.
