Check the hashes on the provably fair. They don't match up. Operator of bitkong was talking to me about it, then when I confronted with the fact the hashes don't match up, nothing.
This site is very questionable.
My investigation continues and I will post evidence in this thread when I have completed my analysis.
But I mean, all you have to do is play on bitkong for about 5 minutes to realize it's a complete scam.
50/50 bet losing 100 times in a row is enough for me.
But then you check the hashes and they don't match up.
The client seed is predictable too. It's using math.random in javascript. All it needs is one result from math.random and it can predict the rest.
But it doesn't matter about predicting, because the hashes don't match up.
So they just send whatever the hell they want and hope no one is checking I guess.
Try it yourself. The site is cheating everyone.
After reading your bad trust comment I don't think I should answer and waste my time, but second time you need to use SHA256 with binary input and not string.
http://www.fileformat.info/tool/hash.htm (not our resource), first time first textbox then with result second textbox.
If we can predict client seed with possible value of 1-1,024 or 1-59,049 it means you can predict server seed with same possibility.
We do not have any result from math.random, just final client seed after you click start button, and you are free to enter client seed manually and do not trust us and your browser at all.
