My comment was about attracting new gamblers via promotional offers and bonuses, which I believe is more effective.
There will be more promotional stuff in the coming days/months. It's just the start. Flush.com is happy to serve their customer as per their interest. Stay tuned for the update.
The site still in development, many more features, upgrade is coming. Without being the best in features, promotion will not much effective. So, I think more promos will be there after they have every popular featured implemented.
