First, it helps to understand the difference between a sweepstakes, contest and lottery. In a sweepstakes, winners are chosen randomly from all participants. In a contest, the winners’ entries are usually judged and are based on a skill or criteria. In a lottery, winners are chosen at random, but in order to enter, the participant must pay. A payment is called a consideration. Only states can hold lotteries, so all private lotteries are illegal.
To avoid being classified as an illegal lottery in any state, your promotion can only have 2 of these 3 elements: prize, chance and consideration. Keep in mind, consideration can mean anything of value, including a fee or even a significant effort (i.e., time spent shooting/submitting a photo, etc.)
Besides federal considerations, every state has its own specifics laws regarding sweepstakes and contests.
Washington does not view entering sweepstakes via entry form, survey, phone, stamped self-addressed envelope or visiting a retail location as consideration.
Contests: are allowed as long as the sponsor awards the prize based on skill and not chance.
Sweepstakes: are allowed as long as the sponsor awards the prize based on chance.
