This is a progression toward attaining the goals we set out to achieve and gives us similar hours to other local casino properties,” said Mark Wong, Vice President and General Manager of Bally’s Chicago. “ Opening our doors 24/7 is an important step as we continue to increase our visitation. Bally’s had earlier stated that going 24/7 would help it get more traction from the longer working hours and, hence, higher revenues. Despite being ranked second in admissions among Illinois’ 15 casinos, it ranked fourth in revenue. The temporary casino at Medinah temple has been operating on a 20-hour daily schedule since opening in September this year. Bally's Chicago has received the green light from the Illinois Gaming Board to operate 24/7, providing gamblers with the opportunity to roll the dice at any hour of the day or night, effective December 27.
