It seems you were right. It is apparently a scam alright! And big one!
I won 4.5 BTC there and issued withdrawn of 4.5 plus my deposit 1 BTC, totally 5.5 BTC. That is about 4K $ now! I've got email that the Bitcoins will be sent on next business day. When there were not sent I wrote them email.
They did not respond. But by mistake one of them sent me email apparently addressed to another man behind it. It says that he shoud decline my request because I "have a bonus". I wrote them again, but they never responded to me.
I am not sure what are they trying to pull off, but I did not use their bonus which they are giving automatically as you send deposit and you cannot say you don't want it and you don't request it, they just automatically add it as you deposit Bitcoins. But I was always betting only with my deposit and I always stayed positive only with my deposit.
It is total scam!
The site is hosted in Netherlands, but it seems people behind it are from Israel. Do someone know to which authorities in Israel and Netherlands should I report this scam? Thanks.
Topic: Bitcoin casino stole mine 2 BTC from me. Beware! (Read 1327 times)
Important update - they contacted me on Monday and sent me all my 2.01 BTC. It was after almost six days and they are saying that they had "technical issue" with new version.
I am not convinced that it's true and it can be possible that they sent them after I created pressure here. But nevertheless Bitcoins are here in my case.
Otherwise the casino is technically nice, but they need to be watched closely.

OK, definitely scam. The person operating Bitoomba - https://bitcointalksearch.org/user/bitoomba-casino-133326 - was logged in here today and did not respond at all. It is now 5.5 days since they took mine Bitcoins...
Beware!
Yup. Beware. Do not gamble, or you WILL lose. :)Well if that was not meant as a joke, it was not funny... :) Scamming casino which already have upper hand by rules of game just simply stealing users money is one of worst type of scammer.
Beware!

I want to warn users against Bitcoin casino Bitoomba, which stole mine 2 BTC from me.
I sent 1.01 BTC on my account there on Sunday October 20th 21:07 GMT. On Tuesday October 22nd I played there and won 1 BTC extra, so I had 2.01 BTC on account there. I issued withdrawal of all 2.01 BTC to my Bitcoin address. Withdrawal is technically automatic and instantaneous there, as they advertise and also as I noticed first time I used it couple of days before. But this time it was different, the Bitcoins never arrived on my address and there is 0 on my Bitoomba account too. I right away contacted their support and until now I sent them multiple emails. It is 4 days now and no one replied.
Together with other smaller indications there is little doubt that it is scammy service or at least they tried to pull scam on me.
Beware!
