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.)
In California, you can't award alcohol as the only prize. Booze can be part of a prize package, however. The state also has other restrictions related to alcohol: you can't force entrants to buy alcoholic beverages as part of entry or force them to visit a liquor store, bar or licensed retailer as part of their entry or to get entry forms. Forms must be available elsewhere as well.
Contests: are allowed as long as they do not charge a consideration. If the contest includes an element of consideration the sponsor must award the contest prize based on skill and not chance and follow all Prize Promotion Laws prize disclosures.
Sweepstakes: are allowed as long as participants do not pay consideration and the sponsor follows all Prize Promotion Laws prize disclosures.
