Sweepstakes, Contests or instant winner games

Yes. It is a problem. You must cut off entry on the date/time published in the official rules. This is one of the reasons it's essential to monitor entry level during the promotion. If you discover entry is low, or only coming from part of the country, there's a lot you can do to stimulate entry during the promotion. But you are not allowed to extend the entry deadline in order to get more entries.

The rules for a promotion are like a contract between you and your audience. As such they not only spell out critical information about your promotion, they provide you with protection and limit your liability. At DJA we always review rules , even for promotions that are repeated from earlier in the year. Sweepstakes laws or the enforcement of those laws are constantly changing, and these changes may require changes to the rules, or even the way the promotion runs or who it's open to. Additionally, if your prize structure or the way you communicate the promotion changes, this may significantly affect your rules, even if your audience remains the same. So the short answer is yes...Have someone review your rules..but be sure they are experts in the area of Sweepstakes.
