Gamblers are placing more and more bets on video slot machines than at Blackjack tables or horse race tracks in Illinois.

The lottery is still the state’s biggest source of wagering revenue but video terminals in casinos, bars, restaurants and stores are poised to challenge that top spot, according to a report by the Illinois Commission on Government Forecasting and Accountability, a bipartisan group that provides economic analysis for the state legislature.

Illinois’s tax collections from gaming climbed to a record of almost $2 billion in the year that ended June 30, according to data going back almost five decades. Video gaming currently represents about 41% of wagering revenue, while lottery makes up nearly 44%.
