Now I'm gonna disclose a unbelievable fact with proof.  Fortunejack dice game is not provably fair at all. It’s just the trick is hard to notice.

I played there for months, and had 181 thousand rolls. At first, I found the game fishy, because when I bet very low, I win like 9 out of 10. But once I tried to increase or double my bet amount, the win chance seemed getting lower and lower notably. At last, I realized that keeping increasing the bet amount tends to trigger the lose streak more likely. The lose streak didn't happen 100% randomly.

Then I posted some articles online about this issue, the FJ support team reached to me and send me my lastest 2000 rolls, I ananysised the data, and get this chart:

The chart shows clearly that the higher you bet, the higher the chance you lose, instead a consistent chance for different bet amounts.
To put it another way, your bet amount will influence the roll outcome.

This is my bet history if you wanna check it yourself: https://1drv.ms/f/s!AnO-if4gpLl5jAaOZTQGWvXz2nr1
I’ll list some data here:
I played with payout 1.5-1.6, win chance is from 66% to 61.87% for the 2000 rolls. The actual average win chance for all 2000 rolls is 65.3%, which is fine and fair. But the win chance for each bet amount decreased while the bet amount was doubled:
Bet amount 0.001, win chance 65.5% (>65.3%)
Bet amount 0.002, win chance 66.8% (>65.3%),
—here is where the trick comes in—
Bet amount 0.004, win chance 65.0% (<65.3%),
Bet amount 0.008, win chance 63.4% (<65.3%),
Bet amount 0.032, win chance 64.3% (<65.3%),
Bet amount 0.064, win chance 55.6% (<65.3%).

See? The higher the bet, the lower the win chance!

Even one lose on a high bet may cost all you won on low bets. So a slightly decrease in win chance with increased bet amount can be a disaster for each player on the long run.

We can see clearly the trend from 2000 rolls. And the trend will be more clearer if Fortunejack team could provide all my history. Every player can ananysis your history like this, or send your data to me. I can defenitly prove Fortunejack dice game is fraud!

Being popular doesn’t mean being safe. The provably fair system can't explain this unfair fact. The outcome shows the truth!

Please, everyone, forward this to your friend and don’t waste your time and money on FortuneJack anymore. You’ll lose everything on FortuneJack dice SCAM.
