When you pick up the first "1" the sequence is waiting a "2".
If you roll another "1" or other than "2" the sequence stopped and restart with the next roll.
That's why every sequence that i writed doesn't win the jackpot.
And that's why the odds is not 1 every 10^6.
Yeah, you are absolutely right that all sequences that you have written will not win the jackpot.
I thought it was only your first 1-1-2-3-x-x that will not the jackpot but I was wrong...
Just got this sequence 1-2-1-2 http://prntscr.com/7dce0o and as you all can see, the 2nd "1-2" is not counted to win jackpot.
It is just a color issue. It is counted to win jackpot.
If is just a color issue the odds are 1 every 10^6... but probably is better if you fix it.
On Wheel, for example, is not a color issue. You don't win the jackpot when you pick up the sequence in a row but only when the green light are on...
