Good article, amazes me that no one did the maths: ... o-winners/
The brochure listed the odds of various correct guesses. Jerry saw that you had a 1-in-54 chance to pick three out of the six numbers in a drawing, winning $5, and a 1-in-1,500 chance to pick four numbers, winning $100. What he now realized, doing some mental arithmetic, was that a player who waited until the roll-down stood to win more than he lost, on average, as long as no player that week picked all six numbers. With the jackpot spilling over, each winning three-number combination would put $50 in the player’s pocket instead of $5, and the four-number winners would pay out $1,000 in prize money instead of $100, and all of a sudden, the odds were in your favor. If no one won the jackpot, Jerry realized, a $1 lottery ticket was worth more than $1 on a roll-down week—statistically speaking.

I'm amazed the numbers stacked up like that with it only working well if nobody won the rollover.

I remember similar stories circulating when the UK lottery first started, it was easier here because you could print those entry forms in advance with the right printer and the machines read 8 lines from each in a couple of seconds. I can't remember any of the details though so it's a bit of a non story. :roll:
