The difference between sweepstakes and contest lies primarily in the method of entry and the criteria for winning. Sweepstakes are games of chance where participants enter for a chance to win a prize, typically without any skill required. In contrast, contests require participants to demonstrate skill or creativity, with winners chosen based on their performance or submissions. Understanding the difference between sweepstakes and contest is essential for both organizers and participants, as it influences the rules, entry methods, and the overall experience of the competition.
