From the announcement:
On July 24, 2017, Fluxx turns 21, and we are celebrating by publishing Drinking Fluxx! With rules that are always changing, Drinking Fluxx will keep you on your toes and shake up any adult party. You've never played a drinking game like this before! Drinking Fluxx will be published under our adult games imprint, Fully Baked Ideas, and will have a $25 MSRP, to help ensure that purchases are made by responsible adults. Drinking Fluxx will not be listed in the Looney Labs family games catalog.
Expect to see Drinking Fluxx on store shelves this July.
