With the deadline for entering the Circa Million and Circa Survivor football games approaching on Saturday, the operator is looking at an overlay of $3.5 million. The Detroit Lions kick off the 2023 NFL season on Thursday, when they travel to Kansas City to play the defending Super Bowl champion Chiefs. Because Sunday has a nearly full schedule of NFL play, the Saturday deadline for entering the Circa competitions has been extended. Circa Sports, in addition to Nevada, offers mobile sports betting in Colorado, Iowa, Illinois, and, eventually, Kentucky.
