But, how the jackpot winner is being chosen from the list of anonymous bets ? Could someone please explain ?
If the Lucky Number is 101 your bet will always win no matter what you selected, and if your bet stake is at least 0.01 BTC, 1 LTC, 1 DASH or 10,000 DOGE and is not part of a losing Toto ~ Parlay slip, it will also be eligible for the 10 BTC Jackpot.
The chance to roll 101 is approx. once out of 1 million rolls.

This changes the house edge if you bet with the minimum required to get the jackpot.
Assuming you get the jackpot every million bets:
For 0.01 BTC:
(0.01*1,000,000) = 10,000 BTC Wagered
0.99% = 99 BTC expected house winnings. 10 BTC won in jackpot.
0.89% effective house edge (99-10/10,000)
For 10k doge = 0.0035 BTC:
(0.0035*1,000,000) = 3,500 BTC Wagered
0.99% = 34.65 BTC expected house winnings. 10 BTC won in jackpot
0.7% effective house edge (34.65-10/3500)
For 1 DASH = 0.013 BTC:
(0.013*1,000,000) = 13,000 BTC Wagered
0.99% = 128.7 expected house winnings. 10 BTC won in jackpot
0.91% effective house edge(128.7-10/13,000)
For 1 LTC = 0.015:
(0.015*1,000,000) = 15,000 BTC wagered
0.99% = 148.5 expected house winnings, 10 BTC won in jackpot
0.92% effective house edge (148.5-10/15,000)
What does this mean?Attempting to win the jackpot slightly reduces the house edge, with the most significant effect seen on dogecoin.
The formula ((1 million * house edge * min bet size) - jackpot size)/(1 million * min bet size) yields the effective house edge
Assuming the rules stay the same,
((1,000,000 * 0.99/100 * min bet) - 10))/(1,000,000 * min bet)
This becomes 0 at around min bet = 0.001 and further on becomes EV+
If doge drops below 10 satoshis, or litecoin or DASH drops under 0.001 BTC, this jackpot will end up causing DirectDice to be EV+
