may i ask what is promo code ?
This is the last piece of information about the codes:
Sorry that code was already used and It can be only used once, I'll share new a ones as son a I fix some vulnerabilities, a few hours back somebody did bets that were too big. The house has lost all its money 
Since the new codes haven't been released yet, it's easy to guess that something still is being improved on the website. A little patience..
