drawings of lottery numbers, a longtime staple of Illinois television, moved last week from over-the-air and cable broadcast to online. The move affects players with Pick 3, Pick 4, Lotto with Extra Shot, and Lucky Day Lotto tickets. The last electromechanical drawing was held on Wednesday, September 30, and the transition was effective on Thursday, October 1.
Traditional lottery drawings use an electromechanical system that utilizes a physical drum stuffed with balls bearing lucky numbers. The Illinois State Lottery’s move to an all-electronic draw includes moving to a computer software system, called a Random Number Generator, which generates random numbers by harvesting them from a mathematical algorithm. Many financial institutions use similar algorithms to encode the secure material they send over digital wires. State lotteries throughout the United States are moving from electromechanical lucky-number drawings to digital draw systems.
