There are two categories of streamlined "Excluded Gambling" activities for you to look at (and, yes, the name "excluded" is a little confusing...). These options have more limits than a permit or license but offer a simpler application process (or none) and no processing fee.
Important Note
The Gambling Control Board currently interprets Minnesota statute to allow an organization to participate in only one of these categories per calendar year. Carefully plan any fundraising activities that involve charitable gambling to avoid unintentionally limiting your options.
