I am at 86% withdrawal, and there is no more winnings even with thousands of spins. Obviously they are a scam site.
At the other hand I am wondering how they do it. I did try several things to 'cheat the cheater'- none of them worked. It is not the cookies that give them my ID- I deleted them during play, I modified them, I blocked them... It should be the script that tells the website- if balance>=??? win % =???. I deleted it, deleted all the external http addresses (it works until you refresh the page), and still in a non winning streak. As soon as I log in with low balance wallet- satoshies are coming... I am sure there should be a way to bypass the id recognition- because at the end it is just a way of communication between my browser and their server. I don't have the knowledge to do it- but some of the people here might figure out a way...
I don't understand what you were trying to accomplish by modifying stuff on your pc. This is a server-side driven game, they know all about your account, identified by your BTC address, it has the associated balance and they can drive the outcome of the spin by simple mathematical function on the balance. IN the most simple way they measure the distance betwenn 0.03 and you balance with asimple subtraction:
distance = 0.03 - balance
the smaller the distance, they make very small or null odds of winning, simple as that.
Anyways it is a scam. Few payouts were made with commercial purposes, I believe. In the last 1000 rolls I hit one minimum payout, which is like 1E-21 chance to happen, so I am done with this.
