However, given the admin's handling of the bug bounty and other bug reports, I wouldn't put too much trust in him or his site now if it even comes back.
I sure hope he does -- with about an hours effort, I've found two more exploitable bugs. One of which is particularly nasty and hard to detect from the servers point of view. paradoxal420's might have found a third, but I'm really not sure how to abuse it (since it's not like you know the outcome before making the server reuse the same seed)
Because if I remember correctly this script uses a horrible checking method and the multiple rolls only get subtracted from your balance once because of the way the requests are processed. But it can get added multiple times. I didn't test it thoroughly, just for like 30 seconds lol. Just going on what I remember from an old version of this script. It might not be the case. Either way I would never deposit on this joke of a site.
Look at the highlighted lines in the screenshot - 3 successive bets with the same rolled number. While there is theoretically a 1 in 100000000 chance of that, it's more likely that this happened due to the site allowing additional rolls to be made before the next rolled number has been generated.
. As soon as it would have been escrowed it would have been mine.
