I don't think so... is 10^8 'cause you must match only 1,2,3,4,5,6,7,8 to win the jackpot
But... if you roll for two times a "1" you must re-start... so probably the odds is from 10^8 to 10^9
My bad, I thought you need to roll 1-9 (not 1-8).
FJ should consider reducing it to "1-6", otherwise it's not very likely anyone will hit that in the next few years.
