Attorney General Mike DeWine sent letters Wednesday informing the facilities of a newly signed law that establishes the registration requirements.

The law also extends the state's current moratorium on the opening of new sweepstakes gambling operations until June 2014. At the storefront operations, patrons buy cards for phone and internet time with chances to play computer games that operate like slot machines with cash prizes.

DeWine is giving cafe operators until June 27 to submit the new affidavits. 

Last month, DeWine staged raids of facilities in Cuyahoga County, resulting in indictments against 11 people and eight companies. He argues they are fronts for illegal gambling and other crime.

State lawmakers also passed a bill that would effectively ban the cafes, which Gov. Kasich is expected to sign.
