This will be a pretty long post about my experience with Cryptoplayer.net
I first found out about them on Bitcointalk when I did not yet have an account here. I decided to get registered today in order to write this.
I hope you will take me seriously even though this is obviously my first post!
I opened an account at Cryptoplayer.net a couple of weeks ago. In the beginning I played with lower bets than I usually do so I could try the website before betting bigger amounts. Everything felt good and I got some wins and some losses. Even though I eventually ended up losing my initial deposit everything felt good so I started to deposit more.
Now I began placing higher bets. I don't remember exactly how much I was betting, but I do know it was at least 5 mBTC on each dice roll. I went for a 20x multiplier. I placed bet after bet, but I kept losing. Since the multiplier was pretty high, I did not think it was that strange to have a long losing streak. But after playing at least 300 dice rolls at 20x, I had still not managed to get a single win.
I started to believe that something was not right. After the 300 roll losing streak I switched to 10x multiplier instead. I played 31 rolls with at least 5 mBTC bet size and lost every time.
Now I started to seriously think that something must be wrong. In order to prove myself wrong I decided to go for 2x multiplier instead. Once again I was betting at least 5 mBTC. I played 15 dice rolls and lost every time.
After this I decided to record a video of some more dice rolls. Right after this insane losing streak I made 20 spins more at 2x multiplier and 5 mBTC bet size. I lost all of those rolls too. I also tried some bets with a lower amount, 1 mBTC, and when I did that I both won and lost an equal amount of times. I have a video of these 20 losing rolls.
The total result of my rolls was that when betting lower, around 1 mBTC, nothing was strange and I both won and lost. But when betting at least 5 mBTC these are the results I got:
At least 300 rolls at 20x : not a single win
31 rolls at 10x : not a single win
35 rolls at 2x : not a single win
And everything happened in a row. I have calculated the probability for this result (including the house edge of 1 %).
The probabilty for such a losing streak is a shockingly low (approximately) 4*10^(-19).
Let's say that we can simulate the same dice rolls one million times every second. Then with this probability we can expect to see the same losing streak once every 80 000 years. That probability is so low that I must believe that something is wrong.
I have sent a couple of emails to Cryptoplayer.net asking if there is something wrong with the results that makes it impossible to win while betting over a certain amount. I don't know if my email was the reason, but just a day or two afterwards the entire website was down for updates. It lasted more than a week and it is now back online again. I have not played again after the update.
Even though I don't actually want to accuse Cryptoplayer.net of deliberitely altering the results, the fact remains that my losing streak is so unlikely that it can be considered impossible. Because of this I consider it to be much more likely that something is wrong with Cryptoplayer.net .
Until they can show what happened and fix the problem I think everyone should avoid playing there.
