People be aware that Bitcoin casino Bitoomba is cheating. I've noticed over this weekend that they changing outcome of their roulette when they need to.

Their roulette is technically provably fair and they are publishing complete results from previous day. But they are cheating in such naive way that they simply change outcome of roulette game when needed and later in published results from previous day they show different outcome, which is correct one but was not used.

For example on Sunday February 2nd around 3:20 am GMT in game number 365526 there were two bets from players, 0.1 BTC on 1 to 18 and 0.075 BTC on 25 to 36. The correct outcome was supposed to be 25, which means winning 0.225 BTC for second bet. But they changed the outcome to 21 and took 0.175 BTC from players...

No doubt this is criminal fraud and I think it is needed to be reported. Do someone know where are they based and to whom should it be reported?

how do ya know the outcome was meant to be 25 tho ??

As I mentioned as part of their provable fair scheme (which is OK) they are publishing list of outcomes of games from previous day. And there is 25. I guess they were hoping nobody will really check outcomes of games they cheated in.

Ok, so if you are doing such detective work comparing past results with what they publish later, then just count up if house edge goes close to 2.7%..
if there is enough games, you should be able to count total winings devided by total losses and you should get close to 0.097 if roulette is fair.. if not, you get lower number.. probably much lower.. so what did you find out?

This is proved cheating in concrete game, that statistics is not needed at all. And it is not single event, I have couple other examples.

And they cheated again!

On Thursday February 6th in game number 371591 there was bet 0.01 BTC on black, on odd and some other bets on specific numbers. The correct outcome calculated beforehand was 8 so bet on black should have won 0.02 BTC. Instead they changed the outcome to 34 so no bet was winning anything...

Seriously, if they post their logs and they don't match the payouts, this is obviously fraud, you don't need to do any statistical analysis.

Someone who gives a crap about a random bitcoin gambling site should probably look into it.  Good thing these things are not regulated or a man might have to get off his ass.

Well and now they removed provable fair roulette and replaced it with non-transparent version where they can cheat.

I think it is pretty obvious what these people are!
