but not by buying tickets, but by playing the options of yes or no on a jackpot winner. just noticed that 5dimes has this line out for jackpot winner:
Mega Millions Jackpot Winner
Fri 3/18
11 Mega Millions Jackpot Winner +175
12 No Jackpot Winner -210
seems like more chances than not there will be no jackpot winner. at 2 drawings a week there hasn't been a jackpot winner in the last 12 drawings. and before that winner it was 7 drawings in a row.
