I think roulet and poker is the key to success to this project because all we know that poker is the most popular casino game online or even in actual. And all we know that roulet is the most easy game that every one who can have ability to play. So I think bitroller have a very good future in this industry.
The main key of success is not what game they are offering but how they manage the site. No matter how many games they have or how popular game they are providing then it will be nothing if they are unable to manage it in proper way. Just take a look at the fact that they did not start it well by using non secured website and the one I reported previously. Also look at the fact that OP is not replying in this thread so far, it is not a good sign already. Professional owner should spend more time to communicate with potential users where he/she announced the project.
