The council voted 6-1 earlier this week to put a hold on issuing licenses until mid-March.
This comes as aldermen plan to discuss regulations of gaming facilities, such as the distance between two locations.
DeKalb Mayor John Rey says a third license was approved just before the halt.
“And I think it made sense for us to deal with those that were already applied, but to offer a moratorium until city council has an opportunity to think through the ongoing guidelines for video gaming establishments in the community," Rey said.
DeKalb currently has around 75 gambling machines.
Illinois lawmakers approved the Video Gaming Act in 2009.
