There arent much other requirements,only others are that we need to deposit so we can win the jackpot
with faucet we cant get a cent even
You're missing an important one: both the betid and the time need to be prime. That's about a 1 in 440 chance if the site is fair, and worse if they decide to cheat. So it's a 1-in-4.4 million chance of hitting the jackpot per bet.
But if you bet 1 satoshi each time, the prize is 0.2 BTC (20 million satoshi) and so it's very +EV for you - in in 4.4 million chance of hitting 20 million times payout... Mr. DaDice Staff is apparently working on a addressing this concern for me.
Let me tell you, its called "JACKPOT" and spelled "
J -
A -
C -
K -
P -
O -
T". The rewards are huge, that is why its called Jackpot, I don't think you understand the term so let me help you out with the first thing you will find on google:
a large cash prize in a game or lottery, especially one that accumulates until it is won.
Also I am certain you don't understand concept of "marketing" that well... Da Dice paid like 1.15 and 0.1 for 200 million rolls event. This event had total 100 million rolls since the last event, there for if I take your example. 1.25 * pow(10,8) = 125000000; 125000000/100000000 = 1.25 satoshis per roll!!!. Now throw in total know amount Da Dice has paid on signature campaign (I read 36 or 38 BTC figure if I am not wrong), divide that by total rolls made so far, (220m?) and just wonder how much Da Dice is spending PER ROLL. In fact this is all an illusion and irrelevant calculations. That including the jackpot money is part of their marketing campaign and efforts.
The
dumbest point of your calculation is that you assume each and every roll being a 1 satoshi bet. The most commited faucet player on Da Dice are known to roll 12500 satoshis per roll.
Now for jackpot calculations, they are pretty simple as well. Chances of hitting 99.99 is in area of 0.01%
in some cases I got maximum of 0.011% probability. Da Dice daily average rolls are about 5 million. So I will take this figure, from 5m rolls per day there should be between 500 to 600 rolls with 99.99 everyday. Bet ID is the first prime number requirement which is currently over 200m. Even in this range there is a huge number of primes, I check randomly and found 5,234,886 primes only in range of 150m to 250m = 5.2%. From 1900m to 2000m I found about 4.2% of primes. Number of primes is certainly too much that is definitely why Da Dice has placed 2 primes rules. Now lets assume 5% being the chance of bet ID being prime, 0.05*0.01=0.0005%. About timestamps primes,, difficulty for me to test that was a little higher, I ran a few tests and was able to calculate 1000 in a single go. I found results vary from 3.2% to 5.1%. But collective average result that I got was 4%
0.04*0.0005=0.00002% probability. Now: 0.00002/100*5000000 = 1
That means probability of hitting Jackpot with both primes rule and having a 99.99 is 1 per day on average of 5 million rolls per day. (Here my and your calculations do not collide as its all mathematical probabilities, it could hit on very next second).
Now any user with some technical knowledge and ability to write a simple bot script in PHP, JAVA, C, ASP to use Da Dice API for rolling, stopping at 99.99 and checking primes and IDs will never pass such a stupid remarks "if the site is fair". Only thing that is not fair here is you
