IF YOU ARE INVESTED AT THIS SITE, PLEASE DIVEST IMMEDIATELY.

Yeah sorry. Had a flaw in simulator... it is fixed now and can reproduce this issue.
Are you ready for your Walk of Shame?
Lol I couldn't help myself

It really does not matter what the house edge is. As long as it is positive then your bankroll will be bleed dry eventually. It can be .01% or 35%, it really doesn't matter. After enough rolls at the certain bet then you will lose. Now that it is public, I am sure that more people are going to be quick to try to exploit it, so don't be surprised when the number of rolls that people are doing is going substantially up all of a sudden but your site's earnings seems to be going down.
This unfortunately is true as well, if more number of users going for those higher payouts chasing +EV, the sooner your bankroll will dry. I wouldn't matter much if someone was doing it individually, but now collectively your bankroll is at risk. Its not a very time consuming fix, I am sure you can do it asap.
The fix being easy doesnt matter if the hurt be massive lol. joter doesnt get that.

simply changing the multiplier to be dependent on the win chance should be a nice and easy fix for this issue, currently the win chance is set by the multiplier which is set by the player, causing the rounding issue.
lol, i like how some people are taking advantage and using hufflepuff as their nick
now this i gotta see

I am not even sure that I would trust the site to pay out large wins that a +EV strategy would result in. The site is very new, has a tiny bankroll, and is acting very unprofessionally.
big point here; even if they decide to pay out, their decisions in handling this entire matter were questionable at best, announcing their site as the subject of this thread was probably the biggest mistake, this is a lose-lose situation for them now.
Yeah, and it's not only them at risk, but also investor's money.
Them being "confident" is totally going to bring a lot of people down.
Time to take a couple of last looks at the site lol.
great point, after this, their site is dead regardless of the outcome. inviting people to come and dump your bankroll and not even consulting with your investors? that's some special publicity right there.
How do you know we didn't notify our investors? Did you ask them? We have notified every single investor on site.
Not sure if you understand how our system works. But one thing is sure, investors have priority before players. And almost all of our funds are on cold wallets. So all will receive their funds if they want to withdraw it.
i don't know how your system is working and I guess, I better don't want to know it! But if such a bug is reported and you almost ignore it and coming up with lame excuses, I am wondering how honest you are.
My site is also only 4 month old, but whatever was reported - be it here on the forum - or via e-mail everything was taken care. So far we have paid 3.65 btc on bug reports. Not a lot but we are still the new kid on the block - but we take care.

Oh dude, ouch. Like I said, if dooglus says there is a problem, there is a problem.
Good luck fixing your site and repairing your reputation.

There was not 1 but 2 +EV issues on site. I hope for their own sake they will fix it soon. I was chatting with jotr on his site, he has fixed his simulator 
(finally!)

Im not sure that do you even understand whats +EV means? Basically you dont need to run a simulation or whatsoever because you just need a simple math for it. If you dont trust this math, I wonder how do you able to code this site on the first hand.
Also some advice for you, if someone like dooglus pointed that there is a flaw in your code then there is a flaw with it since he never claim anything without proper math or test
P.S : you havent answered my question, will you give substrata his bounty? He had posted his address if you are not aware of it yet
1 btc is not something i like to keep on a hot wallet i use for everyday transactions, ill be setting up a new address in the next few minutes and quoting it in the OP. disregard the other address.

wasn't a big deal...
It is indeed not something that will make the user to get rich overnight however the rounding issues are giving player an edge over 30 % and that is indeed a big deal .Also that considering your site has an investment feature than it means investor is getting -EV which serves as a bad reputation for your site.
Your action of being hostile towards someone who give you a heads up also disgraced dooglus' calculation about this issue also is a bad publicity for your site and now people will think twice about investing on your site. In other words you have dug your own grave and it will be just a matter of time before more people read this thread
P.S : are you going to give Substrata the bounty for finding this flaw of your site?
Hostile? We offered him bounty, but he was to greedy to take it. We are small site and don't have huge profit, so we can't afford to reward everyone that says he found a bug, and doesn't want to tell us about it if we don't pay....
I believe he is not that "greedy" merely doing some negotiation to increase the bug bounty , which is everyone will do considering 32 % house edge is a major flaw in your site and thats cause you to lose in long term if anyone finds out about this. Whats more is that you are losing your investor as well in this case because it is -Ev for them
For this 32% issue or whatever it is impossible to reproduce, so you are wrong at some point, not sure where.

Right now, as for the EV bug, the main issue here is how unprofessional the admin reacted.
Though, there seems to be another bug as stated by subSTRATA
And by the way, joter is not the owner of the site. IIRC Kewl owns the site.
And as for subSTRATA extorting it out of joter, I wouldn't really see it as extortion,
since strata never threatened the man in the first place lol

Ok I will quit this thread, and kewl will join soon. Bye.
Well, as by the looks of how you handle things, you sound like Kewl's bitch

I have checked almost all scenarios from that table and all have the same result. And I trust my simulator more than I trust your math
I realize you are justifiably proud of your site which looks very nice and no one likes to be threatened with "I have an exploit give me coins" of which I'm sure you get many. However, if dooglus says there is a problem, there is a problem.
Is it possible that dooglus was doing something with his bets, or seed, or other doogmagicTM that you are not putting into your simulation?
After all, you didn't detect the rounding bug until it was pointed out. Fortunately, the % bets needed to be made were such low probability that it was still a high variance outcome to exploit the player's EV advantage.
You've already graciously offered a 1 BTC reward maybe stick with that as things unfold.
Regardless good luck to you and your site and kudos again to substrata for finding the rounding error.
Only error that we had reproduce is rounding error. The other one is just error in your math. Over and out.

Look you idiot, tell me all parameters that he used and I will check.
But if you bet on payout 3968
And roll under 0.3
You don't make any profit at all in 100 million bets. But if I am missing a parameter that you didn't tell me then it's a different story.

What a moron. I did, along with the precise maths. What more do you want:
Taking the most extremely wrong one:
0.02% chance of 6613x
That's a 0.0002 chance of a profit of 6612, and a (1-0.0002) chance of a profit of -1
Or: 0.0002 * 6612 + (1-0.002)*-1 = 0.3244
...a players advantage of 32.44%
0.02% chance of 6613x
That's a 0.0002 chance of a profit of 6612, and a (1-0.0002) chance of a profit of -1
Or: 0.0002 * 6612 + (1-0.002)*-1 = 0.3244
...a players advantage of 32.44%
And BTW you are wrong
But as you are smart enough you can tell everyone on primedice to take a look. They are welcome!
