Conn. Gen. Stat. § 42-296: Sweepstakes. Restrictions on advertisements.

No person may advertise a sweepstakes if there is any condition or restriction attached to the receipt of any prize a person wins in the sweepstakes, unless the condition or restriction to claim the prize is through any method which does not require any purchase, payment of a fee or any other consideration, such as (1) a telephone call in the participant's extended local calling area, (2) a telephone call to an 800 number, or (3) a visit to a retail establishment in the local marketing area which does not require the participant to attend a sales presentation. For purposes of this section, completing publicity or liability releases, eligibility affidavits or assuming liability for federal, state or local taxes, federal, state or local licenses or registration fees or other similar costs does not constitute a condition or restriction.
