No. That's PrimeDice, and it's provably fair, you can verify its fairness by following the "Provably Fair" guide.
then how come each time you bet big you lose ?
a random game should never have a patter
1. You're winning before you put on a big bet, which is just silly.
2. You're using incredibly high odds and betting straight after one or two losses, I've encountered up to 8 losses on 1.5x consecutively
3. You probably haven't diced before so you think these results are drastic when really they're hardly anything but this.
I've been on pd for over a year, and I can say right now that placing such random bets with no losses before is a newbie move. You lose once or twice on 1.2x before you go all in, not 1.5x....
Tip for the future also, I never bet 1.5x and if I do it's after I see 5+ under 30's in a row, I recommend you follow this tip to avoid future losses.
Is this called pre-rolling? I've heard of a lot of people trying that technique. It seems like it would work, have you tried it with success? Sometimes I do a bunch of rolls and let some really odd results happen, like two roll sin a row under 5, and then I guess it will be a higher number after those 2 rolls.
Rolls does not affect another roll, they are completely random. It doesn't work, even if it works, it would be just your luck, if it really does work all the time, PD would bankrupt already. Varience happens everywhere, you will definitely run into a bad streak at anytime of your run. You can win a few and lose a lot or win a lot and lose a little.
