I'm really digging your website, it was easy to get the hang of. The only thing is that games can sometimes take a while to play. You should try making custom single player bingo games. I'm thinking the kind like in the BigFishBingo app that you can play by yourself... I think it's called "speed bingo". You guys should add something like that to your site.
Wouldn't be the same since it would be one player, but I think you guys could make it into something really unique, as you have already taken regular bingo and found a way to make it work online with bitcoin.
Thanks for your compliment!
Single player games is definitely something we are looking into. It's just not as easy as multiplayer games because you would be playing against the house instead of other players.
Our short term goals are fixing bugs, improving the current experience and adding some new features. After that we will launch an ad campaign so hopefully more players will come so games will start sooner. But even then, singe player games could be really interesting.
