You'll basically have to know what your promotion will do and how that relates to the definitions, such as to a lottery. In my case I am looking at OCC regs. Your regulator should be similar, but not necessarily exactly the same in these areas.
State laws can vary, but the principal of compliance is the same.
12 U.S.C. Sec. 25a Participation by national banks in lotteries and related activities --
Prohibited activities
(2) The term “lottery” includes any arrangement whereby three or more persons (the “participants”) advance money or credit to another in exchange for the possibility or expectation that one or more but not all of the participants (the “winners”) will receive by reason of their advances more than the amounts they have advanced, the identity of the winners being determined by any means which includes--
(A) a random selection;
(B) a game, race, or contest; or
(C) any record or tabulation of the result of one or more events in which any participant has no interest except for its bearing upon the possibility that he may become a winner.
