Test runs aren't unusual for the Kentucky Lottery--they're done at least ten times a day.
Lottery officials said they have various procedures in place to keep everything constant, and it has stayed the same...until Monday's Pick 4 midday drawing.
"In the third chamber there were two of the same ball and in the fourth chamber it was missing a ball...so it changed the odds of the game. And we had to make sure the odds of the game remained the same," said Communications Specialist Sara Westerman, of the Kentucky Lottery.
Westerman said human error caused a ball from the fourth chamber to bounce into the third, so the company remained true to its values: honesty and integrity.
"We made the decision that an additional drawing should be done," she said.
Two drawings, which meant two payouts. The first paid 38 people around $11,000; the second set paid out around $8,000 to 18 winners.
When workers came back the next day, it was business as usual: randomly decide the order the ball cases will be dropped in, two separate companies use two different keys to take the cases out, check and drop the balls into the chambers, re-count, turn on the air to let them fly, then five practice runs (barring unusual number results).
All this before doing the real thing, to guarantee even chances for everyone.
"That's how it has to be done, otherwise no one would play the lottery," said Westerman.
