The game is still alive but I do not think it is good to try it. The representative of the site is gone already IMO as he is inactive for more than a month. If you only want to try, you can use the free btc that you can get by signing up or use the faucet.
Go for another active and trusted website only if you plan to make deposit. It does not worth the risk to spend your money on a new site with inactive representative.
