We have already built several bitcoin gambling games, including with an invest feature. We can build custom games such as black jack, dice, coinflip, wheel's and more. Unlike the other bidders, we actually know how to work with bitcoind (daemon), and bitcoin in general. The others probably have no clue what it is. In addition, our team is native english speakers, meaning there won't be any mistakes due to language barriers. Feel free to message us on skype: acoinllc if you have any questions.
Hope to hear from you soon!
