Instead of asking this, why dont you take look on their site? I do not think that it will do bad to you. As far as I know you can see what games that they provide just by browse it through the site and everything will be there. So why dont you try it before asking some of this question again for the next time.
Anyway, how things going with bitdice lately? Why I only saw 35 people online?
Bitdice seems fine, you only need to see the bet ID and wager leaderboard for proof that there is always a lot of people playing online! I believe that number is not exactly representative of activity, whether at BD or at other sites. For example at BD it's always generally above 30, but I think so many lurkers don't even go to chat (the whale activity is proof!). And at other sites you see many more online but even their admins know it's actually just a lot of multis hoping to catch rain;)
It's bet ID following FIFO model where you reserve next bet ID after current bet is placed, minimum gap i see is at least 50 sometimes 100, so expecting that much users are actually playing. The online stat might be of those logged in their website via browser and connected to chat without counting those are betting with their API keys.
