There is no thread on bitcointalk for their company. So the chances of them being a scam free bitcoin site is much greater. At least you didn't deposit anything, eh? Otherwise it would have been brutal.
If they deleted your account, then that's just more the proof for them being a scam site.
BTW, compare the two sites: coins.bingo and totaldice.com.
Look at the similarities... Almost 100%. Even the games are the same. Now, I am not sure whether totaldice is the operated by the same person, but the totaldice.com forum handle has not been online since September last year. A bit weird if you ask me.
