I have recently signed up on Betcoin.ag. I have got a free 10mBTC bonus as a newbie member. I had to roll slots 500 times using the free bonus in order to release it. I did not released the bonus because I run out of Bitcoin but it was fun to test all the different slots. Therefore, I would like to know if there are further gambling site which are offering such bonues for new members.
You can try LuckyBTcCasino, you can find link in my signature. They offer very nice first deposit bonus for new member, they also have second deposit bonus ( if you make something with first then hit it hard with second is my moto ).
I already suggested some casinos, but LuckyBTcCasino started to work again, new site, very nice games. I think you can try your luck there.
If you ask me Caribbean poker is great, I didn't see such Caribbean on other places, and of course slots, many many slots. I wish you good luck, i hope you will listen my advice.
