Wind Creek Chicago Southland generated some big numbers during its first three weeks of operations in November, boosting statewide casino revenue to its best month of the year. The new south suburban casino, which opened Nov. 11 to large crowds, ranked fifth last month among the state’s 16 casinos with nearly $10.2 million in adjusted gross receipts, and drew more than 141,500 visitors, second only to perennial leader Rivers Casino Des Plaines. “We are thrilled by the enthusiastic response to our opening last month, and we are greeting new guests at the property daily,” Roger Kuehn, Wind Creek’s general manager, said in an emailed statement Monday.
